Proceeds to treat of the arguments put forward by the heretics, not from Scripture, but from their own reason. Those are refuted, who think the substance of the Father and of the Son to be not the same, because everything predicated of God is, in their opinion, predicated of Him according to substance; and therefore it follows, that to beget and to be begotten, or to be begotten and unbegotten, being diverse, are diverse substances; whereas it is here demonstrated that not everything predicated of God is predicated according to substance, in such manner as He is called good and great according to substance, or anything else that is predicated of Him in respect to Himself; but that some things are also predicated of Him relatively, i.e. not in respect to Himself, but to something not Himself, as He is called Father in respect to the Son, and Lord in respect to the creature that serveth Him; in which case, if anything thus predicated relatively, i.e. in respect to something not Himself, is even predicated as happening in time, as e.g. "Lord, thou hast become our refuge," yet nothing happens to God so as to work a change in Him, but He Himself remains absolutely unchangeable in His own nature or essence.

Chap. 1.—What the author entreats from God, what from the reader. In God nothing is to be thought corporeal or changeable.

1. Beginning, as I now do henceforward, to speak of subjects which cannot altogether be spoken as they are thought, either by any man, or, at any rate, not by myself; although even our very thought, when we think of God the Trinity, falls (as we feel) very far short of Him of whom we think, nor comprehends Him as He is; but He is seen, as it is written, even by those who are so great as was the Apostle Paul, "through a glass and in an enigma:"1 first, I pray to our Lord God Himself, of whom we ought always to think, and of whom we are not able to think worthily, in praise of whom blessing is at all times to be rendered, and whom no speech is sufficient to declare, that He will grant me both help for understanding and explaining that which I design, and pardon if in anything I offend. For I bear in mind, not only my desire, but also my infirmity. I ask also of my readers to pardon me, where they may perceive me to have had the desire rather than the power to speak, what they either understand better themselves, or fail to understand through the obscurity of my language, just as I myself pardon them what they cannot understand through their own dullness.

2. And we shall mutually pardon one another the more easily, if we know, or at any rate firmly believe and hold, that whatever is said of a nature, unchangeable, invisible and having life absolutely and sufficient to itself, must not be measured after the custom of things visible, and changeable, and mortal, or not self-sufficient. But although we labor, and yet fail, to grasp and know even those things which are within the scope of our corporeal senses, or what we are ourselves in the tuner man; yet it is with no shamelessness that faithful piety burns after those divine and unspeakable things which are above: piety, I say, not inflated by the arrogance of its own power, but inflamed by the grace of its Creator and Saviour Himself. For with what understanding can man apprehend God, who does not yet apprehend that very understanding itself of his own, by which he desires to apprehend Him? And if he does already apprehend this, let him carefully consider that there is nothing in his own nature better than it; and let him see whether he can there see any outlines of forms, or brightness of colors, or greatness of space, or distance of parts, or extension of size, or any movements through intervals of place, or any such thing at all. Certainly we find nothing of all this in that, than which we find nothing better in our own nature, that is, in our own intellect, by which we apprehend wisdom according to our capacity. What, therefore, we do not find in that which is our own best, we ought not to seek in Him who is far better than that best of ours; that so we may understand God, if we are able, and as much as we are able, as good without quality, great without quantity, a creator though He lack nothing, ruling but from no position, sustaining all things without "having" them, in His wholeness everywhere, yet without place, eternal without time, making things that are changeable, without change of Himself, and without passion. Whoso thus thinks of God, although he cannot yet find out in all ways what He is, yet piously takes heed, as much as he is able, to think nothing of Him that He is not.

Chap. 2.—God the only unchangeable essence.

3. He is, however, without doubt, a substance, or, if it be better so to call it, an essence, which the Greeks call ousi'a. For as wisdom is so called from the being wise, and knowledge from knowing; so from being comes that which we call essence. And who is there that is, more than He who said to His servant Moses, "I am that I am;" and, "Thus shall thou say unto the children of Israel, He who is hath sent me unto you?" But other things that are called essences or substances admit of accidents, whereby a change, whether great or small, is produced in them. But there can be no accident of this kind in respect to God; and therefore He who is God is the only unchangeable substance or essence, to whom certainly BEING itself, whence comes the name of essence, most especially and most truly belongs. For that which is changed does not retain its own being; and that which can be changed, although it be not actually changed, is able not to be that which it had been; and hence that which not only is not changed, but also cannot at all be changed, alone falls most truly, without difficulty or hesitation, under the category of BEING.

Chap. 3.—The argument of the Arians is refuted, which is drawn from the words begotten and unbegotten.

4. Wherefore,—to being now to answer the adversaries of our faith, respecting those things also, which are neither said as they are thought, nor thought as they really are:—among the many things which the Arians are wont to dispute against the Catholic faith, they seem chiefly to set forth this, as their most crafty device, namely, that whatsoever is said or understood of God, is said not according to accident, but according to substance: and therefore, to be unbegotten belongs to the Father according to substance, and to be begotten belongs to the Son according to substance; but to be unbegotten and to be begotten are different; therefore the substance of the Father and that of the Son are different. To whom we reply, If whatever is spoken of God is spoken according to substance, then that which is said, "I and the Father are one," is spoken according to substance. Therefore there is one substance of the Father and the Son. Or if this is not said according to substance, then something is said of God not according to substance, and therefore we are no longer compelled to understand unbegotten and begotten according to substance. it is also said of the Son, "He thought it not robbery to be equal with God." We ask, equal according to what? For if He is not said to be equal according to substance, then they admit that something may be said of God not according to substance. Let them admit, then, that unbegotten and begotten are not spoken according to substance. And if they do not admit this, on the ground that they will have all things to be spoken of God according to substance, then the Son is equal to the Father according to substance.

Chap. 4.—The accidental always implies some change in the thing.

5. That which is accidental commonly implies that it can be lost by some change of the thing to which it is an accident. For although some accidents are said to be inseparable, which in Greek are called achw'rista, as the color black is to the feather of a raven; yet the feather loses that color, not indeed so long as it is a feather, but because the feather is not always. Wherefore the matter itself is changeable; and whenever that animal or that feather ceases to be, and the whole of that body is changed and turned into earth, it loses certainly that color also. Although the kind of accident which is called separable may likewise be lost, not by separation, but by change; as, for instance, blackness is called a separable accident to the hair of men, because hair continuing to be hair can grow white; yet, if carefully considered, it is sufficiently apparent, that it is not as if anything departed by separation away from the head when it grows white, as though blackness departed thence and went somewhere and whiteness came in its place, but that the quality of color there is turned and changed. Therefore there is nothing accidental in God, because there is nothing changeable or that may be lost. But if you choose to call that also accidental, which, although it may not be lost, yet can be decreased or increased,—as, for instance, the life of the soul: for as long as it is a soul, so long it lives, and because the soul is always, it always lives; but because it lives more when it is wise, and less when it is foolish, here, too, some change comes to pass, not such that life is absent, as wisdom is absent to the foolish, but such that it is less;— nothing of this kind, either, happens to God, because He remains altogether unchangeable.

Chap. 5.—Nothing is spoken of God according to accident, but according to substance or according to relation.

6. Wherefore nothing in Him is said in respect to accident, since nothing is accidental to Him, and yet all that is said is not said according to substance. For in created and changeable things, that which is not said according to substance, must, by necessary alternative, be said according to accident. For all things are accidents to them, which can be either lost or diminished, whether magnitudes or qualities; and so also is that which is said in relation to something, as friendships, relationships, services, likenesses, equalities, and anything else of the kind; so also positions and conditions, places and times, acts and passions. But in God nothing is said to be according to accident, because in Him nothing is changeable; and yet everything that is said, is not said, according to substance. For it is said in relation to something, as the Father in relation to the Son and the Son in relation to the Father, which is not accident; because both the one is always Father, and the other is always Son: yet not "always," meaning from the time when the Son was born [natus], so that the Father ceases not to be the Father because the Son never ceases to be the Son, but because the Son was always born, and never began to be the Son. But if He had begun to be at any time, or were at any time to cease to be, the Son, then He would be called Son according to accident. But if the Father, in that He is called the Father, were so called in relation to Himself, not to the Son; and the Son, in that He is called the Son, were so called in relation to Himself, not to the Father; then both the one would be called Father, and the other Son, according to substance. But because the Father is not called the Father except in that He has a Son, and the Son is not called Son except in that He has a Father, these things are not said according to substance; because each of them is not so called in relation to Himself, but the terms are used reciprocally and in relation each to the other; nor yet according to accident, because both the being called the Father, and the being called the Son, is eternal and unchangeable to them. Wherefore, although to be the Father and to be the Son is different, yet their substance is not different; because they are so called, not according to substance, but according to relation, which relation, however, is not accident, because it is not changeable.

Chap. 6.—Reply is made to the cavils of the heretics in respect to the same words begotten and unbegotten.

7. But if they think they can answer this reasoning thus,—that the Father indeed is so called in relation to the Son, and the Son in relation to the Father, but that they are said to be unbegotten and begotten in relation to themselves, not in relation each to the other; for that it is not the same thing to call Him unbegotten as it is to call Him the Father, because there would be nothing to hinder our calling Him unbegotten even if He had not begotten the Son; and if any one beget a son, he is not therefore himself unbegotten, for men, who are begotten by other men, themselves also beget others; and therefore they say the Father is called Father in relation to the Son, and the Son is called Son in relation to the Father, but unbegotten is said in relation to Himself, and begotten in relation to Himself; and therefore, if whatever is said in relation to oneself is said according to substance, while to be unbegotten and to be begotten are different, then the substance is different:—if this is what they say, then they do not understand that they do indeed say something that requires more careful discussion in respect to the term unbegotten, because neither is any one therefore a father because unbegotten, nor therefore unbegotten because he is a father, and on that account he is supposed to be called unbegotten, not in relation to anything else, but in respect to himself; but, on the other hand, with a wonderful blindness, they do not perceive that no one can be said to be begotten except in relation to something. For he is therefore a son because begotten; and because a son, therefore certainly begotten. And as is the relation of son to father, so is the relation of the begotten to the begetter; and as is the relation of father to son, so is the relation of the begetter to the begotten. And therefore any one is understood to be a begetter under one notion, but understood to be unbegotten under another. For though both are said of God the Father, yet the former is said in relation to the begotten, that is to the Son, which, indeed, they do not deny; but that He is called unbegotten, they declare to be said in respect to Himself. They say then, If anything is said to be a father in respect to itself, which cannot be said to be a son in respect to itself, and whatever is said in respect to self is said according to substance; and He is said to be unbegotten in respect to Himself, which the Son cannot be said to be; therefore He is said to be unbegotten according to substance; and because the Son cannot be so said to be, therefore He is not of the same substance. This subtlety is to be answered by compelling them to say themselves according to what it is that the Son is equal to the Father; whether according to that which is said in relation to Himself, or according to that which is said in relation to the Father. For it is not according to that which is said in relation to the Father, since in relation to the Father He is said to be Son, and the Father is not Son, but Father. Since Father and Son are not so called in relation to each other in the same way as friends and neighbors are; for a friend is so called relatively to his friend, and if they love each other equally, then the same friendship is in both; and a neighbor is so called relatively to a neighbor, and because they are equally neighbors to each other (for each is neighbor to the other, in the same degree as the other is neighbor to him), there is the same neighborhood in both. But because the Son is not so called relatively to the Son, but to the Father. it is not according to that which is said in relation to the Father that the Son is equal to the Father; and it remains that He is equal according to that which is said in relation to Himself. But whatever is said in relation to self is said according to substance: it remains therefore that He is equal according to substance; therefore the substance of both is the same. But when the Father is said to be unbegotten, it is not said what He is, but what He is not; and when a relative term is denied, it is not denied according to substance, since the relative itself is not affirmed according to substance.

Chap. 7.—The addition of a negative does not change the predicament.

8. This is to be made clear by examples. And first we must notice, that by the word begotten is signified the same thing as is signified by the word son. For therefore a son, because begotten, and because a son, therefore certainly begotten. By the word unbegotten, therefore, it is declared that he is not son. But begotten and unbegotten are both of them terms suitably employed; whereas in Latin we can use the word "filius," but the custom of the language does not allow us to speak of "infilius." It makes no difference, however, in the meaning if he is called "non filius;" just as it is precisely the same thing if he is called "non genitus," instead of "ingenitus." For so the terms of both neighbor and friend are used relatively, yet we cannot speak of "invicinus" as we can of "inimicus." Wherefore, in speaking of this thing or that, we must not consider what the usage of our own language either allows or does not allow, but what clearly appears to be the meaning of the things themselves. Let us not therefore any longer call it unbegotten, although it can be so called in Latin; but instead of this let us call it not begotten, which means the same. Is this then anything else than saying that he is not a son? Now the prefixing of that negative particle does not make that to be said according to substance, which, without it, is said relatively; but that only is denied, which, without it, was affirmed, as in the other predicaments. When we say he is a man, we denote substance. He therefore who says he is not a man, enunciates no other kind of predicament, but only denies that. As therefore I affirm according to substance in saying he is a man, so I deny according to substance in saying he is not a man. And when the question is asked how large he is? and I say he is quadrupedal, that is, four feet in measure, I affirm according to quantity, and he who says he is not quadrupedal, denies according to quantity. I say he is white, I affirm according to quality; if I say he is not white, I deny according to quality. I say he is near, I affirm according to relation; if I say he is not near, I deny according to relation. I affirm according to position, when I say he lies down; I deny according to position, when I say he does not lie down. I speak according to condition/when I say he is armed; I deny according to condition, when I say he is not armed; and it comes to the same thing as if I should say he is unarmed. I affirm according to time, when I say he is of yesterday; I deny according to time, when I say he is not of yesterday. And when I say he is at Rome, I affirm according to place; and I deny according to place, when I say he is not at Rome. I affirm according to the predicament of action, when I say he smites; but if I say he does not smite, I deny according to action, so as to declare that he does not so act. And when I say he is smitten, I affirm according to the predicament of passion; and I deny according to the same, when I say he is not smitten. And, in a word, there is no kind of predicament according to which we may please to affirm anything, without being proved to deny according to the same predicament, if we prefix the negative particle. And since this is so, if I were to affirm according to substance, in saying son, I should deny according to substance, in saying not son. But because I affirm relatively when I say he is a son, for I refer to the father therefore I deny relatively if I say he is not a son, for I refer the same negation to the father, in that I wish to declare that he has not a parent. But if to be called son is precisely equivalent to the being called begotten (as we said before), then to be called not begotten is precisely equivalent to the being called not son. But we deny relatively when we say he is not son, therefore we deny relatively when we say he is not begotten. Further, what is unbegotten, unless not begotten? We do not escape, therefore, from the relative predicament, when he is called unbegotten. For as begotten is not said in relation to self, but in that he is of a begetter; so when one is called unbegotten, he is not so called in relation to himself, but it is declared that he is not of a begetter. Both meanings, however, turn upon the same predicament, which is called that of relation. But that which is asserted relatively does not denote substance, and accordingly, although begotten and unbegotten are diverse, they do not denote a different substance; because, as son is referred to father, and not son to not father, so it follows inevitably that begotten must be referred to begetter, and not-begotten to not-begetter.

Chap. 8.—Whatever is spoken of God according to substance, as spoken of each person severally, and together of the Trinity itself. One essence in God, and three, in Greek, hypostases, in Latin, persons.

9. Wherefore let us hold this above all, that whatsoever is said of that most eminent and divine loftiness in respect to itself, is said in respect to substance, but that which is said in relation to anything, is not said in respect to substance, but relatively; and that the effect of the same substance in Father and Son and Holy Spirit is, that whatsoever is said of each in respect to themselves, is to be taken of them, not in the plural in sum, but in the singular. For as the Father is God, and the Son is God, and the Holy Spirit is God, which no one doubts to be said in respect to substance, yet we do not say that the very Supreme Trinity itself is three Gods, but one God. So the Father is great, the Son great, and the Holy Spirit great; yet not three greats, but one great. For it is not written of the Father alone, as they perversely suppose, but of the Father and the Son and the Holy Spirit, "Thou art great: Thou art God alone." And the Father is good, the Son good, and the Holy Spirit good; yet not three goods, but one good, of whom it is said, "None is good, save one, that is, God." For the Lord Jesus, lest He should be understood as man only by him who said, "Good Master," as addressing a man, does not therefore say, There is none good, save the Father alone; but, "None is good, save one, that is, God." For the Father by Himself is declared by the name of Father; but by the name of God, both Himself and the Son and the Holy Spirit., because the Trinity is one God. But position, and condition, and places, and times, are not said to be in God properly, but metaphorically and through similitudes. For He is both said to dwell between the cherubims, which is spoken in respect to position; and to be covered with the deep as with a garment, which is said in respect to condition; and "Thy years shall have no end," which is said in respect of time; and, "If I ascend up into heaven, Thou art there," which is said in respect to place. And as respects action (or making), perhaps it may be said most truly of God alone, for God alone makes and Himself is not made. Nor is He liable to passions as far as belongs to that substance whereby He is God. So the Father is omnipotent, the Son omnipotent, and the Holy Spirit is omnipotent; yet not three omnipotents, but one omnipotent: "For of Him are all things, and through Him are all things, and in Him are all things; to whom be glory." Whatever, therefore, is spoken of God in respect to Himself, is both spoken singly of each person, that is, of the Father, and the Son, and the Holy Spirit; and together of the Trinity itself, not plurally but in the singular. For inasmuch as to God it is not one thing to be, and another thing to be great, but to Him it is the same thing to be, as it is to be great; therefore, as we do not say three essences, so we do not say three greatnesses, but one essence and one greatness. I say essence, which in Greek is called ousi'a, and which we call more usually substance.

10. They indeed use also the word hypostasis; but they intend to put a difference, I know not what, between ousi'a and hypostasis: so that most of ourselves who treat these things in the Greek language, are accustomed to say, mi'an ousi'an trei^s uposta'seis or in Latin, one essence, three substances?

Chap. 9.—The three persons not properly so called [in a human sense].

But because with us the usage has already obtained, that by essence we understand the same thing which is understood by substance; we do not dare to say one essence, three substances, but one essence or substance and three persons: as many writers in Latin, who treat of these things, and are of authority, have said, in that they could not find any other more suitable way by which to enunciate in words that which they understood without words. For, in truth, as the Father is not the Son, and the Son is not the Father, and that Holy Spirit who is also called the gift of God is neither the Father nor the Son, certainly they are three. And so it is said plurally, "I and my Father are one." For He has not said, "is one," as the Sabellians say; but, "are one." Yet, when the question is asked, What three? human language labors altogether under great poverty of speech. The answer, however, is given, three "persons," not that it might be [completely] spoken, but that it might not be left [wholly] unspoken.

Chap. 10.—Those things which belong absolutely to God as an essence, are spoken of the Trinity in the singular, not in the plural.

11. As, therefore, we do not say three essences, so we do not say three greatnesses, or three who are great. For in things which are great by partaking of greatness, to which it is one thing to be, and another to be great, as a great house, and a great mountain, and a great mind; in these things, I say, greatness is one thing, and that which is great because of greatness is another, and a great house, certainly, is not absolute greatness itself. But that is absolute greatness by which not only a great house is great, and any great mountain is great, but also by which every other thing whatsoever is great, which is called great; so that greatness itself is one thing, and those things are another which are called great from it. And this greatness certainly is primarily great, and in a much more excellent way than those things which are great by partaking of it. But since God is not great with that greatness which is not Himself, so that God, in being great, is, as it were, partaker of that greatness;— otherwise that will be a greatness greater than God, whereas there is nothing greater than God; therefore, He is great with that greatness by which He Himself is that same greatness. And, therefore, as we do not say three essences, so neither do we say three greatnesses; for it is the same thing to God to be, and to be great. For the same reason neither do we say three greats, but one who is great; since God is not great by partaking of greatness, but He is great by Himself being great, because He Himself is His own greatness. Let the same be said also of the goodness, and of the eternity, and of the omnipotence of God, and, in short, of all the predicaments which can be predicated of God, as He is spoken of in respect to Himself, not metaphorically and by similitude, but properly, if indeed anything can be spoken of Him properly, by the mouth of man.

Chap. 11.—What is said relatively in the Trinity,

12. But whereas, in the same Trinity, some things severally are specially predicated, these are in no way said in reference to themselves in themselves, but either in mutual reference, or in respect to the creature; and, therefore, it is manifest that such things are spoken relatively, not in the way of substance. For the Trinity is called one God, great, good, eternal, omnipotent; and the same God Himself may be called His own deity, His own magnitude, His own goodness, His own, eternity, His own omnipotence: but the Trinity cannot in the same way be called the Father, except perhaps metaphorically, in respect to the creature, on account of the adoption of sons. For that which is written, "Hear, O Israel: the Lord our God is one Lord," ought certainly not to be understood as if the Son were excepted, or the Holy Spirit were excepted; which one Lord our God we rightly call also our Father, as regenerating us by His grace. Neither can the Trinity in any wise be called the Son, but it can be called, in its entirety, the Holy Spirit, according to that which is written, "God is a Spirit;" because both the Father is a spirit and the Son is a spirit, and the Father is holy and the Son is holy. Therefore, since the Father, the Son and the Holy Spirit are one God, and certainly God is holy, and God is a spirit, the Trinity can be called also the Holy Spirit. But yet that Holy Spirit, who is not the Trinity, but is understood as in the Trinity, is spoken of in His proper name of the Holy Spirit relatively, since He is referred both to the Father and to the Son, because the Holy Spirit is the Spirit both of the Father and of the Son. But the relation is not itself apparent in that name, but it is apparent when He is called the gift of God; for He is the gift of the Father and of the Son, because "He proceeds from the Father," as the Lord says; and because that which the apostle says, "Now, if any man have not the Spirit of Christ, he is none of His," he says certainly of the Holy Spirit Himself. When we say, therefore, the gift of the giver, and the giver of the gift, we speak in both cases relatively in reciprocal reference. Therefore the Holy Spirit is a certain unutterable communion of the Father and the Son; and on that account, perhaps, He is so called, because the same name is suitable to both the Father and the Son. For He Himself is called specially that which they are called in common; because both the Father is a spirit and the Son a spirit, both the Father is holy and the Son holy. In order, therefore, that the communion of both may be signified from a name which is suitable to both, the Holy Spirit is called the gift of both. And this Trinity is one God, alone, good, great, eternal, omnipotent; itself its own unity, deity, greatness, goodness, eternity, omnipotence.

Chap. 12.—In relative things that are reciprocal, names are sometimes wanting.

13. Neither ought it to influence us—since we have said that the Holy Spirit is so called relatively, not the Trinity itself, but He who is in the Trinity—that the designation of Him to whom He is referred, does not seem to answer in turn to His designation. For we cannot, as we say the servant of a master, and the master of a servant, the son of a father and the father of a son, so also say here—because these things are said relatively. For we speak of the Holy Spirit of the Father; but, on the other hand, we do not speak of the Father of the Holy Spirit, test the Holy Spirit should be understood to be His Son. So also we speak of the Holy Spirit of the Son; but we do not speak of the Son of the Holy Spirit, lest the Holy Spirit be understood to be His Father. For it is the case in many relatives, that no designation is to be found by which those things which bear relation to each other may [in name] mutually correspond to each other. For what is more clearly spoken relatively than the word earnest? Since it is referred to that of which it is an earnest, and an earnest is always an earnest of something. Can we then, as we say, the earnest of the Father and of the Son, say in turn, the Father of the earnest or the Son of the earnest? But, on the other hand, when we say the gift of the Father and of the Son, we cannot indeed say the Father of the gift, or the Son of the gift; but that these may correspond mutually to each other, we say the gift of the giver and the giver of the gift; because here a word in use may be found, there it cannot.

Chap. 13.—How the word beginning (principium) is spoken relatively in the Trinity.

14. The Father is called so, therefore, relatively, and He is also relatively said to be the Beginning, and whatever else there may be of the kind; but He is called the Father in relation to the Son, the Beginning in relation to all things, which are from Him. So the Son is relatively so called; He is called also relatively the Word and the Image. And in all these appellations He is referred to the Father, but the Father is called by none of them. And the Son is also called the Beginning; for when it was said to Him, "Who art Thou?" He replied, "Even the Beginning, who also speak to you." But is He, pray, the Beginning of the Father? For He intended to show Himself to be the Creator when He said that He was the Beginning, as the Father also is the beginning of the creature in that all things are from Him. For creator, too, is spoken relatively to creature, as master to servant. And so when we say, both that the Father is the Beginning, and that the Son is the Beginning, we do not speak of two beginnings of the creature; since both the Father and the Son together is one beginning in respect to the creature, as one Creator, as one God. But if whatever remains within itself and produces or Works anything is a beginning to that thing which it produces or works; then we cannot deny that the Holy Spirit also is rightly called the Beginning, since we do not separate Him from the appellation of Creator: and it is written of Him that He works; and assuredly, in working, He remains within Himself; for He Himself is not changed and turned into any of the things which He works. And see what it is that He works: "But the manifestation of the Spirit," he says, "is given to every man to profit withal. For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit; to another faith by the same Spirit; to another the gifts of healing by the same Spirit; to another the working of miracles; to another prophecy; to another the discerning of spirits; to another divers kinds of tongues; to another the interpretation of tongues: but all these worketh that one and the self-same Spirit, dividing to every man severally as He will;" certainly as God—for who can work such great things but God?—but "it is the same God which worketh all in all." For if we are asked point by point concerning the Holy Spirit, we answer most truly that He is God; and with the Father and the Son together He is one God. Therefore, God is spoken of as one Beginning in respect to the creature, not as two or three beginnings.

Chap. 14.—The Father and the Son the only beginning (principium) of the Holy Spirit.

15. But in their mutual relation to one another in the Trinity itself, if the begetter is a beginning in relation to that which he begets, the Father is a beginning in relation to the Son, because the begets Him; but whether the Father is also a beginning in relation to the Holy Spirit, since it is said, "He proceeds from the Father," is no small question. Because, if it is so, He will not only be a beginning to that thing which He begets or makes, but also to that which He gives. And here, too, that question comes to light, as it can, which is wont to trouble many, Why the Holy Spirit is not also a son, since He, too, comes forth from the Father, as it is read in the Gospel? For the Spirit came forth, not as born, but as given; and so He is not called a son, because He was neither born, as the Only-begotten, nor made, so that by the grace of God He might be born into adoption, as we are. For that which is born of the Father, is referred to the Father only when called Son, and so the Son is the Son of the Father, and not also our Son; but that which is given is referred both to Him who gave, and to those to whom He gave; and so the Holy Spirit is not only the Spirit of the Father and of the Son who gave Him, but He is also called ours, who have received Him: as "The salvation of the Lord," who gives salvation, is said also to be our salvation, who have received it. Therefore, the Spirit is both the Spirit of God who gave Him, and ours who have received Him. Not, indeed, that spirit of ours by which we are, because that is the spirit of a man which is in him; but this Spirit is ours in another mode, viz. that in which we also say, "Give us this day our bread." Although certainly we have received that spirit also, which is called the spirit of a man. "For what hast thou," he says, "which thou didst not receive?" But that is one thing, which we have received that we might be; another, that which we have received that we might be holy. Whence it is also written of John, that he "came in the spirit and power of Elias;" and by the spirit of Elias is meant the Holy Spirit, whom Elias received. And the same thing is to be understood of Moses, when the Lord says to him, "And I will take of thy spirit, and will put it upon them;" that is, I will give to them of the Holy Spirit, which I have already given to thee. If, therefore, that also which is given has him for a beginning by whom it is given, since it has received from no other source that which proceeds from him; it must be admitted that the Father and the Son are a Beginning of the Holy Spirit, not two Beginnings; but as the Father and Son are one God, and one Creator, and one Lord relatively to the creature, so are they one Beginning relatively to the Holy Spirit. But the Father, the Son, and the Holy Spirit is one Beginning in respect to the creature, as also one Creator and one God.

Chap. 15.—Whether the Holy Spirit was a gift before as well as after He was given.

16. But it is asked further, whether, as the Son, by being born, has not only this, that He is the Son, but that He is absolutely; and so also the Holy Spirit, by being given, has not only this, that He is given, but that He is absolutely—whether therefore He was, before He was given, but was not yet a gift; or whether, for the very reason that God was about to give Him, He was already a gift also before He was given. But if He does not proceed unless when He is given, and assuredly could not proceed before there was one to whom He might be given; how, in that case, was He [absolutely] in His very substance, if He is not unless because He is given? just as the Son, by being born, not only has this, that He is a Son, which is said relatively, but His very substance absolutely, so that He is. Does the Holy Spirit proceed always, and proceed not in time, but from eternity, but because He so proceeded that He was capable of being given, was already a gift even before there was one to whom He might be given? For there is a difference in meaning between a gift and a thing that has been given. For a gift may exist even before it is given; but it cannot be called a thing that has been given unless it has been given.

Chap. 16.—What is said of God in time, is said relatively, not accidentally.

17. Nor let it trouble us that the Holy Spirit, although He is co- eternal with the Father and the Son, yet is called something which exists in time; as, for instance, this very thing which we have called Him, a thing that has been given. For the Spirit is a gift eternally, but a thing that has been given in time. For if a lord also is not so called unless when he begins to have a slave, that appellation likewise is relative and in time to God; for the creature is not from all eternity, of which He is the Lord. How then shall we make it good that relative terms themselves are not accidental, since nothing happens accidentally to God in time, because He is incapable of change, as we have argued in the beginning of this discussion? Behold! to be the Lord, is not eternal to God; otherwise we should be compelled to say that the creature also is from eternity, since He would not be a lord from all eternity unless the creature also was a servant from all eternity. But as he cannot be a slave who has not a lord, neither can he be a lord who has not a slave. And if there be any one who says that God, indeed, is alone eternal, and that times are not eternal on account of their variety and changeableness, but that times nevertheless did not begin to be in time (for there was no time before times began, and therefore it did not happen to God in time that He should be Lord, since He was Lord of the very times themselves, which assuredly did not begin in time): what will he reply respecting man, who was made in time, and of whom assuredly He was not the Lord before he was of whom He was to be Lord? Certainly to be the Lord of man happened to God in time. And that all dispute may seem to be taken away, certainly to be your Lord, or mine, who have only lately begun to be, happened to God in time. Or if this, too, seems uncertain on account of the obscure question respecting the soul, what is to be said of His being the Lord of the people of Israel? since, although the nature of the soul already existed, which that people had (a matter into which we do not now inquire), yet that people existed not as yet, and the time is apparent when it began to exist. Lastly, that He should be Lord of this or that tree, or of this or that corn crop, which only lately began to be, happened in time; since, although the matter itself already existed, yet it is on, thing to be Lord of the matter (materiae), another to be Lord of the already created nature (naturae). For man, too, is lord of the wood at one time, and at another he is lord of the chest, although fabricated of that same wood; which he certainly was not at the time when he was already the lord of the wood. How then shall we make it good that nothing is said of God according to accident, except because nothing happens to His nature by which He may be changed, so that those things are relative accidents which happen in, connection with some change of the things of which they are spoken. As a friend is so called relatively: for he does not begin to be one, unless when he has begun to love; therefore some change of will takes place, in order that he may be called a friend. And money, when it is called a price, is spoken of relatively, and yet it was not changed when it began to be a price; nor, again, when it is called a pledge, or any other thing of the kind. If, therefore, money can so often be spoken of relatively with no change of itself, so that neither when it begins, nor when it ceases to be so spoken of, does any change take place in that nature or form of it, whereby it is money; how much more easily ought we to admit, concerning that unchangeable substance of God, that something may be so predicated relatively in respect to the creature, that although it begin to be so predicated in time, yet nothing shall be understood to have happened to the substance itself of God, but only to that creature in respect to which it is predicated? "Lord," it is said, "Thou hast been made our refuge." God, therefore, is said to be our refuge relatively, for He is referred to us, and He then becomes our refuge when we flee to Him; pray does anything come to pass then in His nature, which, before we fled to Him, was not? In us therefore some change does take place; for we were worse before we fled to Him, and we become better by fleeing to Him: but in Him there is no change. So also He begins to be our Father, when we are regenerated through His grace, since He gave us power to become the sons of God. Our substance therefore is changed for the better, when we become His sons; and He at the same time begins to be our Father, but without any change of His own substance. Therefore that which begins to be spoken of God in time, and which was not spoken of Him before, is manifestly spoken of Him relatively; yet not according to any accident of God, so that anything should have happened to Him, but clearly according to some accident of that, in respect to which God begins to be called something relatively. When a righteous man begins to be a friend of God, he himself is changed; but far be it from us to say, that God loves any one in time with as it were a new love, which was not in Him before, with whom things gone by have not passed away and things future have been already done. Therefore He loved all His saints before the foundation of the world, as He predestinated them; but when they are converted and find them; then they are said to begin to be loved by Him, that what is said may be said in that way in which it can be comprehended by human affections. So also, when He is said to be wroth with the unrighteous, and gentle with the good, they are changed, not He: just as the light is troublesome to weak eyes, pleasant to those that are strong; namely, by their change, not its own.

BOOK VI.

The question is proposed, how the apostle calls Christ "the power of God, and the wisdom of God." And an argument is raised, whether the Father is not wisdom Himself, but only the Father of wisdom; or whether wisdom begat wisdom. But the answer to this is deferred for a little, while the unity and equality of the Father, and of the Son, and of the Holy Ghost, are proved; and that we ought to believe in a Trinity, not in a threefold (triplicem) God. Lastly, that saying of Hilary is explained, eternity in the Father, appearance in the Image, use in the Gift.

Chap. 1.—The Son, according to the apostle, is the power and wisdom of the Father. Hence the reasoning of the Catholics against the earlier Arians. A difficulty is raised, whether the Father is not wisdom Himself, but only the Father of wisdom.

1. Some think themselves hindered from admitting the equality of the Father, Son, and Holy Spirit, because it is written, "Christ, the power of God, and the wisdom of God;" in that, on this ground, there does not appear to be equality; because the Father is not Himself power and wisdom, but the begetter of power and wisdom. And, in truth, the question is usually asked with no common earnestness, in what way God can be called the Father of power and wisdom. For the apostle says, "Christ the power of God, and the wisdom of God." And hence some on our side have reasoned in this way against the Arians, at least against those who at first set themselves up against the Catholic faith. For Arius himself is reported to have said, that if He is a Son, then He was born; if He was born, there was a time when the Son was not: not understanding that even to be born is, to God, from all eternity; so that the Son is co-eternal with the Father, as the brightness which is produced and is spread around by fire is co-eval with it, and would be co-eternal, if fire were eternal. And therefore some of the later Arians have abandoned that opinion, and have confessed that the Son of God did not begin to be in time. But among the arguments which those on our side used to hold against them who said that there was a time when the Son was not, some were wont to introduce such an argument as this: If the Son of God is the power and wisdom of God, and God was never without power and wisdom, then the Son is co-eternal with God the Father; but the apostle says, "Christ the power of God, and the wisdom of God;" and a man must be senseless to say that God at any time had not power or wisdom; therefore there was no time when the Son was not.

2. Now this argument compels us to say that God the Father is not wise, except by having the wisdom which He begat, not by the Father in Himself being wisdom itself. Further, if it be so, just as the Son also Himself is called God of God, Light of Light, we must consider whether He can be called wisdom of wisdom, if God the Father is not wisdom itself, but only the begetter of wisdom. And if we hold this, why is He not the begetter also of His own greatness, and of His own goodness, and of His own eternity, and of His own omnipotence; so that He is not Himself His own greatness, and His own goodness, and His own eternity, and His own omnipotence; but is great with that greatness which He begat, and good with that goodness, and eternal with that eternity, and omnipotent with that omnipotence, which was born of Him; just as He Himself is not His own wisdom, but is wise with that wisdom which was born of Him? For we need not be afraid of being compelled to say that there are many sons of God, over and above the adoption of the creature, co-eternal with the Father, if He be the begetter of His own greatness, and goodness, and eternity, and omnipotence. Because it is easy to reply to this cavil, that it does not at all follow, because many things are named, that He should be the Father of many co-eternal sons; just as it does not follow that He is the Father of two sons, because Christ is said to be the power of God, and the wisdom of God. For that certainly is the power which is the wisdom, and that is the wisdom which is the power; and in like manner, therefore, of the rest also; so that that is the greatness which is the power, or any other of those things which either have been mentioned above, or may hereafter be mentioned.

Chap. 2 .—What is said of the Father and Son together, and what not.

3. But if nothing is spoken of the Father as such, except that which is spoken of Him in relation to the Son, that is, that He is His father, or begetter, or beginning; and if also the begetter is by consequence a beginning to that which he begets of himself; but whatever else is spoken of Him is so spoken as with the Son, or rather in the Son; whether that He is great with that greatness which He begat, or just with that justice which He begat, or good with that goodness which He begat, or powerful with that force or power which He begat, or wise with that wisdom which He begat: yet the Father is not said to be greatness itself, but the begetter of greatness; but the Son, as He is called the Son as such, is not so called with the Father but in relation to the Father, so is not great in and by himself, but with the Father, of whom He is the greatness; and so also is called wise with the Father, of whom He Himself is the wisdom; just as the Father is called wise with the Son, because He is wise with that wisdom which He begat; therefore the one is not called without the other, whatever they are called in respect to themselves; that is, whatever they are called that manifests their essential nature, both are so called together;—if these things are so, then the Father is not God without the Son, nor the Son God without the Father, but both together are God. And that which is said, "In the beginning was the Word," means that the Word was in the Father, Or if "In the beginning" is intended to mean, Before all things; then in that which follows, "And the Word was with God," the Son alone is understood to be the Word, not the Father and Son together, as though both were one Word (for He is the Word in the same way as He is the Image, but the Father and Son are not both together the Image, but the Son alone is the Image of the Father: just as He is also the Son of the Father, for both together are not the Son). But in that which is added, "And the Word was with God," there is much reason to understand thus: "The Word," which is the Son alone, "was with God," which is not the Father alone, but God the Father and the Son together. But what wonder is there, if this can be said in the case of some twofold things widely different from each other? For what are so different as soul and body? Yet we can say the soul was with a man, that is, in a man; although the soul is not the body, and man is both soul and body together. So that what follows in the Scripture, "And the Word was God," may be understood thus: The Word, which is not the Father, was God together with the Father. Are we then to say thus, that the Father is the begetter of His own greatness, that is, the begetter of His own power, or the begetter of His own wisdom; and that the Son is greatness, and power, and wisdom; but that the great, omnipotent, and wise God, is both together? How then God of God, Light of Light? For not both together are God of God, but only the Son is of God, that is to say, of the Father; nor are both together Light of Light, but the Son only is of Light, that is, of the Father. Unless, perhaps, it was in order to intimate and inculcate briefly that the Son is co-eternal with the Father, that it is said, God of God, and Light of Light, or anything else of the like kind: as if to say, This which is not the Son without the Father, of this which is not the Father without the Son; that is, this Light which is not Light without the Father, of that Light, viz. the Father, which is not Light without the Son; so that, when it is said, God which is not the Son without the Father, and of God which is not the Father without the Son, it may be perfectly understood that the Begetter did not precede that which He begot. And if this be so, then this alone cannot be said of them, namely, this or that of this or that, which they are not both together. Just as the Word cannot be said to be of the Word, because both are not the Word together, but only the Son; nor image of image, since they are not both together the image; nor Son of Son, since both together are not the Son, according to that which is said, "I and my Father are one." For "we are one" means, what He is, that am I also; according to essence, not according to relation.

Chap. 3.—That the unity of the essence of the Father and the Son is to be gathered from the words, "we are one." The Son is equal to the Father both in wisdom and in all other things.

4. And I know not whether the words, "They are one," are ever found in Scripture as spoken of things of which the nature is different. But if there are more things than one of the same nature, and they differ in sentiment, they are not one, and that so far as they differ in sentiment. For if the disciples were already one by the fact of being men, He would not say, "That they may be one, as we are one," when commending them to the Father. But because Paul and Apollos were both alike men, and also of like sentiments, "He that planteth," he says, "and he that watereth are one." When, therefore, anything is so called one, that it is not added in what it is one, and yet more things than one are called one, then the same essence and nature is signified, not differing nor disagreeing. But when it is added in what it is one, it may be meant that something is made one out of things more than one, though they are different in nature. As soul and body are assuredly not one; for, what are so different? unless there be added, or understood in what they are one, that is, one man, or one animal [person]. Thence the apostle says, "He who is joined to a harlot, is one body;" he does not say, they are one or he is one; but he has added "body," as though it were one body composed by being joined together of two different bodies, masculine and feminine. And, "He that is joined unto the Lord," he says," is one spirit:" he did not say, he that is joined unto the Lord is one, or they are one; but he added, "spirit" For the spirit of man and the Spirit of God are different in nature; but by being joined they become one spirit of two different spirits, so that the Spirit of God is blessed and perfect without the human spirit, but the spirit of man cannot be blessed without God. Nor is it without cause, I think, that when the Lord said so much in the Gospel according to John, and so often, of unity itself, whether of His own with the Father, or of ours interchangeably with ourselves; He has nowhere said, that we are also one with Himself, but, "that they may be one as we also are one." Therefore the Father and the Son are one, undoubtedly according to unity of substance; and there is one God, and one great, and one wise, as we have argued.

5. Whence then is the Father greater? For if greater, He is greater by greatness; but whereas the Son is His greatness, neither assuredly is the Son greater than He who begat Him, nor is the Father greater than that greatness, whereby He is great; therefore they are equal. For whence is He equal, if not in that which He is, to whom it is not one thing to be, and another to be great? Or if the Father is greater in eternity, the Son is not equal in anything whatsoever. For whence equal? If you say in greatness, that greatness is not equal which is less eternal, and so of all things else. Or is He perhaps equal in power, but not equal in wisdom? But how is that power which is less wise, equal? Or is He equal in wisdom, but not equal in power? But how is that wisdom equal which is less powerful? It remains, therefore, that if He is not equal in anything, He is not equal in all. But Scripture proclaims, that "He thought it not robbery to be equal with God." Therefore any adversary of the truth whatever, provided he feels bound by apostolical authority, must needs confess that the Son is equal with God in each one thing whatsoever. Let him choose that which he will; from it he will be shown, that He is equal in all things which are said of His substance.

Chap. 4.—The same argument continued.

6. For in like manner the virtues which are in the human mind, although each has its own several and different meaning, yet are in no way mutually separable; so that, for instance, whosoever were equal in courage, are equal also in prudence, and temperance, and justice. For if you say that such and such men are equal in courage, but that one of them is greater in prudence, it follows that the courage of the other is less prudent, and so neither are they equal in courage, since the courage of the former is more prudent. And so you will find it to be the case with the other virtues, if you consider them one by one. For the question is not of the strength of the body, but of the courage of the mind. How much more therefore is this the case in that unchangeable and eternal substance, which is incomparably more simple than the human mind is? Since, in the human mind, to be is not the same as to be strong, or prudent, or just, or temperate; for a mind can exist, and yet have none of these virtues. But in God to be is the same as to be strong, or to be just, or to be wise, or whatever is said of that simple multiplicity, or multifold simplicity, whereby to signify His substance. Wherefore, whether we say God of God in such way that this name belongs to each, yet not so that both together are two Gods, but one God; for they are in such way united with each other, as according to the apostle's testimony may take place even in diverse and differing substances; for both the Lord alone is a Spirit, and the spirit of a man alone is assuredly a spirit; yet, if it cleave to the Lord, "it is one spirit:" how much more there, where there is an absolutely inseparable and eternal union, so that He may not seem absurdly to be called as it were the Son of both, when He is called the Son of God, if that which is called God is only said of both together. Or perhaps it is, that whatever is said of God so as to indicate His substance, is not said except of both together, nay of the Trinity itself together? Whether therefore it be this or that (which needs a closer inquiry), it is enough for the present to see from what has been said, that the Son is in no respect equal with the Father, if He is found to be unequal in anything which has to do with signifying His substance, as we have already shown. But the apostle has said that He is equal. Therefore the Son is equal with the Father in all things, and is of one and the same substance.

Chap. 5.—The Holy Spirit also is equal to the Father and the Son in all things.

7. Wherefore also the Holy Spirit consists in the same unity of substance, and in the same equality. For whether He is the unity of both, or the holiness, or the love, or therefore the unity because the love, and therefore the love because the holiness, it is manifest that He is not one of the two, through whom the two are joined, through whom the Begotten is loved by the Begetter, and loves Him that begat Him, and through whom, not by participation, but by their own essence, neither by the gift of any superior, but by their own, they are "keeping the unity of the Spirit in the bond of peace;" which we are commanded to imitate by grace, both towards God and towards ourselves. "On which two commandments hang all the law and the prophets." So those three are God, one, alone, great, wise, holy, blessed. But we are blessed from Him, and through Him, and in Him; because we ourselves are one by His gift, and one spirit with Him, because our soul cleaves to Him so as to follow Him. And it is good for us to cleave to God, since He will destroy every man who is estranged from Him. Therefore the Ho!y Spirit, whatever it is, is something common both to the Father and Son. But that communion itself is consubstantial and co- eternal; and if it may fitly be called friendship, let it be so called; but it is more aptly called love. And this is also a substance, since God is a substance, and "God is love," as it is written. But as He is a substance together with the Father and the Son, so that substance is together with them great, and together with them good, and together with them holy, and whatsoever else is said in reference to substance; since it is not one thing to God to be, and another to be great or to be good. and the rest, as we have shown above. For if love is less great therein [i.e. in God] than wisdom, then wisdom is loved in less degree than according to what it is; love is therefore equal, in order that wisdom may be loved according to its being; but wisdom is equal with the Father, as we have proved-above; therefore also the Holy Spirit is equal; and if equal, equal in all things, off account of the absolute simplicity which is in that substance. And therefore they are not more than three: One who loves Him who is from Himself, and One who loves Him from whom He is, and Love itself. And if this last is nothing, how is "God love"? If it is not substance, how is God substance?

Chap. 6.—How God is a substance both simple and manifold.

8. But if it is asked how that substance is both simple and manifold: consider, first, why the creature is manifold, but in no way really simple. And first, all that is body is composed ,certainly of parts; so that therein one part is greater, another less, and the whole is greater than any part whatever or how great soever. For the heaven and the earth are parts of the Whole bulk of the world; and the earth alone, and the heaven alone, is composed of innumerable parts; and its third part is less than the remainder, and the half of it is less than the whole; and the whole body of the world, which is usually called by its two parts, viz. the heaven and the earth, is certainly greater than the heaven alone or the earth alone. And in each several body, size is one thing, color another shape another; for the same color and the same shape may remain with diminished size; and the same shape and the same size may remain with the color changed; and the same shape not remaining, yet the thing may be just as great, and of the same color. And whatever other things are predicated together of body can be changed either all together, or the larger part of them without the rest. And hence the nature of body is conclusively proved to be manifold, and in no respect simple. The spiritual creature also, that is, the soul, is indeed the more simple of the two if compared with the body; but if we omit the comparison with the body, it is manifold, and itself also not simple. For it is on this account more simple than the body, because it is not diffused in bulk through extension of place, but in each body, it is both whole in the whole, and whole in each several part of it; and, therefore, when anything takes place in any small particle whatever of the body, such as the soul can feel, although it does not take place in the whole body, yet the whole soul feels it, since the whole soul is not unconscious of it. But, nevertheless, since in the soul also it is one thing to be skillful, another to be indolent, another to be intelligent, another to be of retentive memory; since cupidity is one thing, fear another, joy another, sadness another; and since things innumerable, and in innumerable ways, are to be found in the nature of the soul, some without others, and some more, some less; it is manifest that its nature is not simple, but manifold. For nothing simple is changeable, but every creature is changeable.

Chap. 7.—God is a Trinity, but not triple.

But God is truly called in manifold ways, great, good, wise, blessed, true, and whatsoever other thing seems to be said of Him not unworthily: but His greatness is the same as His wisdom; for He is not great by bulk, but by power; and His goodness is the same as His wisdom and greatness, and His truth the same as all those things; and in Him it is not one thing to be blessed, and another to be great, or wise, or true, or good, or in a word to be Himself.

9. Neither, since He is a Trinity, is He therefore to be thought triple (triplex) otherwise the Father alone, or the Son alone, will be less than the Father and Son together. Although, indeed, it is hard to see how we can say, either the Father alone, or the Son alone; since both the Father is with the Son, and the Son with the Father, always and inseparably: not that both are the Father, or both are the Son; but because they are always one in relation to the other, and neither the one nor the other alone. But because we call even the Trinity itself God alone, although He is always with holy spirits and souls, but say that He only is God, because they are not also God with Him; so we call the Father the Father alone, not because He is separate from the Son, but because they are not both together the Father.

Chap. 8.—No addition can be made to the nature of God.

Since, therefore, the Father alone, or the Son alone, or the Holy Spirit alone, is as great as is the Father and the Son and the Holy Spirit together, in no manner is He to be called threefold. Forasmuch as bodies increase by union of themselves. For although he who cleaves to his wife is one body; yet it is a greater body than if it were that of the husband alone, or of the wife alone. But in spiritual things, when the less adheres to the greater, as the creature to the Creators the former becomes greater than it was, not the latter. For in those things which are not great by bulk, to be greater is to be better. And the spirit of any creature becomes better, when it cleaves to the Creator, than if it did not so cleave; and therefore also greater because better. "He," then, that is joined unto the Lord is one spirit:" but yet the Lord does not therefore become greater, although he who is joined to the Lord does so. In God Himself, therefore when the equal Son, or the Holy Spirit equal to the Father and the Son, is joined to the equal Father, God does not become greater than each of them severally; because that perfectness cannot increase. But whether t be the Father, or the Son, or the Holy Spirit He is perfect, and God the Father the Son and the Holy Spirit is perfect; and therefore He is a Trinity rather than triple.

Chap. 9.—Whether one or the three persons together are called the only God.

10. And since we are showing how we can say the Father alone, because there is no Father in the Godhead except Himself, we must consider also the opinion which holds that the only true God is not the Father alone, but the leather and the Son and the Holy Spirit. For if any one should ask whether the Father alone is God, how can it be replied that He is not, unless perhaps we were to say that the Father indeed is God, but that He is not God alone, but that the Father, Son, and Holy Spirit are God alone? But then what shall we do with that testimony of the Lord? For He was speaking to the Father, and had named the Father as Him to whom He was speaking, when He says, "And this is life eternal, that they may know Thee the one true God." And this the Arians indeed usually take, as if the Son were not true God. Passing them by, however, we must see whether, when it is said to the Father, "That they may know Thee the one true God," we are forced to understand it as if He wished to intimate that the Father alone is the true God; lest we should not understand any to be God, except the three together, the Father, Son, and Holy Spirit. Are we therefore, from the testimony of the Lord, both to call the Father the one true God, and the Son the one true God, and the Holy Spirit the one true God, and the Father, the Son, and the Holy Spirit together, that is, the Trinity itself together, not three true Gods but one true God? Or because He added, "And Jesus Christ whom Thou hast sent," are we to supply "the one true God;" so that the order of the words is this, "That they may know Thee, and Jesus Christ whom Thou hast sent, the one true God?" Why then did He omit to mention the Holy Spirit? Is it because it follows, that whenever we name One who cleaves to One by a harmony so great that through this harmony both are one, this harmony itself must be understood, although it is not mentioned? For in that place, too, the apostle seems as it were to pass over the Holy Spirit; and yet there, too, He is understood, where he says, "All are yours, and ye are Christ's, and Christ is God's." And again, "The head of the woman is the man, the head of the man is Christ, and the head of Christ is God." But again, if God is only all three together, how can God be the head of Christ, that is, the Trinity the head of Christ, since Christ is in the Trinity in order that it may be the Trinity? Is that which is the Father with the Son, the head of that which is the Son alone? For the Father with the Son is God, but the Son alone is Christ: especially since it is the Word already made flesh that speaks; and according to this His humiliation also, the Father is greater than He, as He says, "for my Father is greater than I;" so that the very being of God, which is one to Him with the Father, is itself the head of the man who is mediator, which He is alone. For if we rightly call the mind the chief thing of man, that is, as it were the head of the human substance, although the man himself together with the mind is man; why is not the Word with the Father, which together is God, much more suitably and much more the head of Christ, although Christ as man cannot be understood except with the Word which was made flesh? But this, as we have already said, we shall consider somewhat more carefully hereafter. At present the equality and one and the same substance of the Trinity has been demonstrated as briefly as possible, that in whatever way that other question be determined, the more rigorous discussion of which we have deferred, nothing may hinder us from confessing the absolute equality of the Father, Son, and Holy Spirit.

Chap. X.—Of the attributes assigned by Hilary to each person. The Trinity is represented in things that are made.

11. A certain writer, when he would briefly intimate the special attributes of each of the persons in the Trinity, tells us that "Eternity is in the Father, form in the Image, use in the Gift." And since he was a man of no mean authority in handling the Scriptures, and in the assertion of the faith, for it is Hilary who put this in his book (On the Trinity, ii.); I have searched into the hidden meaning of these words as far as I can, that is, of the Father, and the Image, and the Gift, of eternity, and of form, and of use. And I do not think that he intended more by the word eternity, than that the Father has not a father from whom He is; but the Son is from the Father, so as to be, and so as to be co-eternal with Him. For if an image perfectly fills the measure of that of which it is the image, then the image is made equal to that of which it is the image, not the latter to its own image. And in respect to this image he has named form, I believe on account of the quality of beauty, where there is at once such great fitness, and prime equality, and prime likeness, differing in nothing, and unequal in no respect, and in no part unlike, but answering exactly to Him whose image it is: where there is prime and absolute life, to whom it is not one thing to live, and another to be, but the same thing to be and to live; and prime and absolute intellect, to whom it is not one thing to live, another to understand, but to understand is to live, and is to be, and all things are one: as though a perfect Word (John i. 1), to which nothing is wanting, and a certain skill of the omnipotent and wise God, full of all living, unchangeable sciences, and all one in it, as itself is one from one, with whom it is one. Therein God knew all things which He made by it; and therefore, while times pass away and succeed, nothing passes away or succeeds to the knowledge of God. For things which are created are not therefore known by God, because they have been made; and not rather have been therefore made, even although changeable, because they are known unchangeably by Him. Therefore that unspeakable conjunction of the Father and His image is not without fruition, without love, without joy. Therefore that love, delight, felicity, or blessedness, if indeed it can be worthily expressed by any human word, is called by him, in short, Use; and is the Holy Spirit in the Trinity, not begotten, but the sweetness of the begetter and of the begotten, filling all creatures according to their capacity with abundant bountifulness and copiousness, that they may keep their proper order and rest satisfied in their proper place.

12. Therefore all these things which are made by divine skill, show in themselves a certain unity, and form, and order; for each of them is both some one thing, as are the several natures of bodies and dispositions of souls; and is fashioned in some form, as are the figures or qualities of bodies, and the various learning or skill of souls; and seeks or preserves a certain order, as are the several weights or combinations of bodies and the loves or delights of souls. When therefore we regard the Creator, who is understood by the things that are made we must needs understand the Trinity of whom there appear traces in the creature, as is fitting. For in that Trinity is the supreme source of all things, and the most perfect beauty, and the most blessed delight. Those three, therefore, both seem to be mutually determined to each other, and are in themselves infinite. But here in corporeal things, one thing alone is not as much as three together, and two are something more than one; but in that highest Trinity one is as much as the three together, nor are two anything more than one. And They are infinite in themselves. So both each are in each, and all in each, and each in all, and all in all, and all are one. Let him who sees this, whether in part, or "through a glass and in an enigma," rejoice in knowing God; and let him honor Him as God, and give thanks; but let him who does not see it, strive to see it through piety, not to cavil at it through blindness. Since God is one, but yet is a Trinity. Neither are we to take the words, "of whom, and through whom, and to whom are all things," as used indiscriminately [i.e., to denote a unity without distinctions]; nor yet to denote many gods, for "to Him, be glory for ever and ever. Amen."

BOOK VII.

The question is explained, which had been deferred in the previous book, viz. that God the Father, who begat the Son, His power and wisdom, is not only the Father of power and wisdom, but also Himself power and wisdom; and similarly the Holy Spirit: yet that there are not three powers or three wisdoms, but one power and one wisdom, as there is one God and one essence. Inquiry is then made, why the Latins say one essence, three persons, in God; but the Greeks, one essence, three substances or hypostases: and both modes of expression are shown to arise from the necessities of speech, that we might have an answer to give when asked, what three, while truly confessing that there are three, viz. the Father, and the Son, and the Holy Spirit.

Chap. 1.—Augustine returns to the question, whether each person of the Trinity by Itself is wisdom. With what difficulty, or in what way, the proposed question is to be solved.

1. Let us now inquire more carefully, so far as God grants, into that which a little before we deferred; whether each person also in the Trinity can also by Himself and not with the other two be called God, or great, or wise, or true, or omnipotent, or just, or anything else that can be said of God, not relatively, but absolutely; or whether these things cannot be said except when the Trinity is understood. For the question is raised,—because it is written, "Christ the power of God, and the wisdom of God,"— whether He is so the Father of His own wisdom and His own power, as that He is wise with that wisdom which He begat, and powerful with that power which He begat; and whether, since He is always powerful and wise, He always begat power and wisdom. For if it be so, then, as we have said, why is He not also the Father of His own greatness by which He is great, and of His own goodness by which He is good, and of His own justice by which He is just, and whatever else there is? Or if all these things are understood, although under more names than one, to be in the same wisdom and power, so that that is greatness which is power, that is goodness which is wisdom, and that again is wisdom which is power, as we have already argued; then let us remember, that when I mention any one of these, I am to be taken as if I mentioned all. It is asked, then, whether the Father also by Himself is wise, and is Himself His own wisdom itself; or whether He is wise in the same way as He speaks. For He speaks by the Word which He begat, not by the word which is uttered, and sounds, and passes away, but by the Word which was with God, and the Word was God, and all things were made by Him: by the Word which is equal to Himself, by whom He always and unchangeably utters Himself. For He is not Himself the Word, as He is not the Son nor the image. But in speaking (putting aside those words of God in time which are produced in the creature, for they sound and pass away,—-in speaking then) by that co-eternal Word, He is not understood singly, but with that Word itself, without whom certainly He does not speak. Is He then in such way wise as He is one who speaks, so as to be in such way wisdom, as He is the Word, and so that to be the Word is to be wisdom, that is, also to be power, so that power and wisdom and the Word may be the same, and be so called relatively as the Son and the image: and that the Father is not singly powerful or wise, but together with the power and wisdom itself which He begat (genuit); just as He is not singly one who speaks, but by that Word and together with that Word which He begat; and in like way great by that and together with that greatness, which He begat? And if He is not great by one thing, and God by another, but great by that whereby He is God, because it is not one thing to Him to be great and another to be God; it follows that neither is He God singly, but by that and together with that deity (deitas) which He begat; so that the Son is the deity of the Father, as He is the wisdom and power of the Father, and as He is the Word and image of the Father. And because it is not one thing to Him to be, another to be God, the Son is also the essence of the Father, as He is His Word and image. And hence also—except that He is the Father [the Unbegotten]—the Father is not anything unless because He has the Son; so that not only that which is meant by Father (which it is manifest He is not called relatively to Himself but to the Son, and therefore is the Father because He has the Son), but that which He is in respect to His own substance is so called, because He begat His own essence. For as He is great, only with that greatness which He begat, so also He is, only with that essence which He begat; because it is not one thing to Him to be, and another to be great. Is He therefore the Father of His own essence, in the same way as He is the Father of His own greatness, as He is the Father of His own power and wisdom? since His greatness is the same as His power, and His essence the same as His greatness.

2. This discussion has arisen from that which is written, that "Christ is the power of God, and the wisdom of God." Wherefore our discourse is compressed into these narrow limits, while we desire to speak things unspeakable; that either we must say that Christ is not the power of God and the wisdom of God, and so shamelessly and impiously resist the apostle; or we must acknowledge that Christ is indeed the power of God and the wisdom of God, but that His Father is not the Father of His own power and wisdom, which is not less impious; for so neither will He be the Father of Christ, because Christ is the power of God and the wisdom of God; or that the Father is not powerful with His own power, or wise with His own wisdom: and who shall dare to say this? Or yet, again, that we must understand, that in the Father it is one thing to be, another thing to be wise, so that He is not by that by which He is wise: a thing usually understood of the soul, which is at some times unwise, at others wise; as being by nature changeable, and not absolutely and perfectly simple. Or, again, that the Father is not anything in respect to His own substance; and that not only that He is the Father, but that He is, is said relatively to the Son. How then can the Son be of the same essence as the Father, seeing that the Father, in respect to Himself, is neither His own essence, nor is at all in respect to Himself, but even His essence is in relation to the Son? But, on the contrary, much more is He of one and [the same essence, since the Father and Son are one and the same essence; seeing that the Father has His being itself not in respect to Himself, but to the Son, which essence He begat, and by which essence He is whatever He is. Therefore neither [person] is in respect to Himself alone; and both exist relatively the one to the other. Or is the Father alone not called Father of himself, but whatever He is called, is called relatively to the Son, but the Son is predicated of in reference to Himself? And if it be so, what is predicated of Him in reference to Himself? Is it His essence itself? But the Son is the essence of the Father, as He is the power and wisdom of the Father, as He is the Word of the Father, and the image of the Father. Or if the Son is called essence in reference to Himself, but the Father is not essence, but the begetter of the essence, and is not in respect to Himself, but is by that very essence which He begat; as He is great by that greatness which He begat: therefore the Son is also called greatness in respect to Himself; therefore He is also [called, in like manner, power, and wisdom, and word, and image. But what can be more absurd than that He should be called image in respect to Himself? Or if image and word are not the very same with power and wisdom, but the former are spoken relatively, and the latter in respect to self, not to another; then we get to this, that the Father is not wise with that wisdom which He begat, because He Himself cannot be spoken relatively to it, and it cannot be spoken relatively to Him. For all things which are said relatively are said reciprocally; therefore it remains that even in essence the Son is spoken of relatively to the Father. But from this is educed a most unexpected sense: that essence itself is not essence, or at least that, when it is called essence, not essence but something relative is intimated. As when we speak of a master, essence is not intimated, but a relative which has reference to a slave; but when we speak of a man, or any such thing which is said in respect to self not to something else, then essence is intimated. Therefore when a man is called a master, man himself is essence, but he is called master relatively; for he is called man in respect to himself, but master in respect to his slave. But in regard to the point from which we started, if essence itself is spoken relatively, essence itself is not essence. Add further, that all essence which is spoken of relatively, is also something, although the relation be, taken away; as e.g. in the case of a man who is a master, and a man who is a slave, and a horse that is a beast of burden, and money that is a pledge, the man, and the horse, and the money are spoken in respect to themselves, and are substances or essences; but master, and slave, and beast of burden, and pledge, are spoken relatively to something. But if there were not a man, that is, some substance, there would be none who could be called relatively a master; and if there were no horse having a certain essence, there would be nothing that could be called relatively a beast of burden; so if money were not some kind of substance, it could not be called relatively a pledge. Wherefore, if the Father also is not something in respect to Himself then there is no one at all that can be spoken of relatively to something. For it is not as it is with color. The color of a thing is referred to the thing colored, and color is not spoken at all in reference to substance, but is always of something that is colored; but that thing of which it is the color, even if it is referred to color in respect to its being colored, is yet, in respect to its being a body, spoken of in respect to substance. But in no way may we think, in like manner, that the Father cannot be called anything in respect to His own substance, but that whatever He is called, He is called in relation to the Son; while the same Son is spoken of both in respect to His own substance and in relation to the Father, when He is called great greatness, and powerful power, plainly in respect to Himself, and the greatness and power of the great and powerful Father, by which the Father is great and powerful. It is not so; but both are substance, and both are one substance. And as it is absurd to say that whiteness is not white, so is it absurd to say that wisdom is not wise; and as whiteness is called white in respect to itself, so also wisdom is called wise in respect to itself. But the whiteness of a body is not an essence, since the body itself is the essence, and that is a quality of it; and hence also a body is said from that quality to be white, to which body to be is not the same thing as to be white. For the form in it is one thing, and the color another; and both are not in themselves, but in a certain bulk, which bulk is neither form nor color, but is formed and colored. True wisdom is both wise, and wise in itself. And since in the case of every soul that becomes wise by partaking of wisdom, if it again becomes foolish, yet wisdom in itself remains; nor when that soul was changed into folly is the wisdom likewise so changed; therefore wisdom is not in him who becomes wise by it, in the same manner as whiteness is in the body which is by it made white. For when the body has been changed into another color, that whiteness will not remain, but will altogether cease to be. But if the Father who begat wisdom is also made wise by it, and to be is not to Him the same as to be wise, then the Son is His quality, not His offspring; and there will no longer be absolute simplicity in the Godhead. But far be it from being so, since in truth in the Godhead is absolutely simple essence, and therefore to be is there the same as to be wise. But if to be is there the same as to be wise, then the Father is not wise by that wisdom which He begat; otherwise He did not beget it, but it begat Him. For what else do we say when we say, that to Him to be is the same as to be wise, unless that He is by that whereby He is wise? Wherefore, that which is the cause to Him of being wise, is itself also the cause to Him that He is; and accordingly, if the wisdom which He begat is the cause to Him of being wise, it is also the cause to Him that He is; and this cannot be the case, except either by begetting or by creating Him. But no one ever said in any sense that wisdom is either the begetter or the creator of the Father; for what could be more senseless? Therefore both the Father Himself is wisdom, and the Son is in such way called the wisdom of the Father, as He is called the light of the Father; that is, that in the same manner as light from light, and yet both one light, so we are to understand wisdom of wisdom, and yet both one wisdom; and therefore also one essence, since, in God, to be, is the same as to be wise. For what to be wise is to wisdom, and to be able is to power, and to be eternal is to eternity, and to be just to justice, and to be great to greatness, that being itself is to essence. And since in the Divine simplicity, to be wise is nothing else than to be, therefore wisdom there is the same as essence.

Chap. 2.—The Father and the Son are together one wisdom, as one essence, although not together one Word.

3. Therefore the Father and the Son together are one essence, and one greatness, and one truth, and one wisdom. But the Father and Son both together are not one Word, because both together are not one Son. For as the Son is referred to the Father, and is not so called in respect to Himself, so also the Word is referred to him whose Word it is, when it is called the Word. Since He is the Son in that He is the Word, and He is the Word in that He is the Son. Inasmuch, therefore, as the Father and the Son together are certainly not one Son, it follows that the Father and the Son together are not the one Word of both. And therefore He is not the Word in that He is wisdom; since He is not called the Word in respect to Himself, but only relatively to Him whose Word He is, as He is called the Son in relation to the Father; but He is wisdom by that whereby He is essence. And therefore, because one essence. one wisdom. But since the Word is also wisdom, yet is not thereby the Word because He is wisdom for He is understood to be the Word relatively, but wisdom essentially: let us understand, that when He is called the Word, it is meant, wisdom that is born, so as to be both the Son and the Image; and that when these two words are used, namely wisdom (is) born, in one of the two, namely barn, both Word, and Image, and Son, are understood, and in all these names essence is not expressed, since they are spoken relatively; but in the other word, namely wisdom, since it is spoken also in respect to substance, for wisdom is wise in itself, essence also is expressed, and that being of His which is to be wise. Whence the Father and Son together are one wisdom, because one essence, and singly wisdom of wisdom, as essence of essence. And hence they are not therefore not one essence, because the Father is not the Son, and the Son is not the Father, or because the Father is un-begotten, but the Son is begotten: since by these names only their relative attributes are expressed. But both together are one wisdom and one essence; in which to be, is the same as to be wise. And both together are not the Word or the Son, since to be is not the same as to be the Word or the Son, as we have already sufficiently shown that these terms are spoken relatively.

Chap. 3.—Why the Son chiefly is intimated in the Scriptures by the name of wisdom, while both the Father and the Holy Spirit are wisdom. That the Holy Spirit, together with the Father and the Son, is one wisdom.

4. Why, then, is scarcely anything ever said in the Scriptures of wisdom, unless to show that it is begotten or created of God?—begotten in the case of that Wisdom by which all things are made; but created or made, as in men, when they are converted to that Wisdom which is not created anti made but begotten, and are so enlightened; for in these men themselves there comes to be something which may be called their wisdom: even as the Scriptures foretell or narrate, that "the Word was made flesh, and dwelt among us;" for in this way Christ was made wisdom, because He was made man. Is it on this account that Wisdom Goes not speak m these books, nor is anything spoken of it, except to declare that it is born of God, or made by Him (although the Father is Himself wisdom), namely, because wisdom ought to be commended and imitated by us, by the imitation of which we are fashioned [rightly]? For the Father speaks it, that it may be His Word: yet not as a word producing a sound proceeds from the mouth, or is thought before it is pronounced. For this word is completed in certain spaces of time, but that is eternal, and speaks to us by enlightening us, what ought to be spoken to men, both of itself and of the Father. And therefore He says, "No man knoweth the Son, but the Father; neither knoweth any man the Father. save the Son, and he to whomsoever the Son will reveal Him:" since the Father reveals by the Son, that is, by His Word. For if that word which we utter, and which is temporal and transitory, declares both itself, and that of which we speak, how much more the Word of God, by which all things are made? For this Word so declares the Father as He is the Father; because both itself so is, and is that which is the Father, in so far as it is wisdom and essence. For in so far as it is the Word. it is not what the Father is: because the Word is not the Father, and Word is spoken relatively, as is also Son, which assuredly is not the Father. And therefore Christ is the power and wisdom of God, because He Himself, being also power and wisdom, is from the Father, who is power and wisdom; as He is light of the Father, who is light, and the fountain of life with God the Father, who is Himself assuredly the fountain of life. For "with Thee," He says, "is the fountain of life, and in Thy light shall we see light."' Because, "as the Father hath life in Himself, so hath He given to the Son to have life in Himself:" and, "He was the true Light, which lighteth every man that cometh into the world:" and this light, "the Word," was "with God;" but "the Word also was God;" and "God is light, and in Him is no darkness at all:" but a light that is not corporeal, but spiritual; yet not in such way spiritual, that it was wrought by illumination, as it was said to the apostles, "Ye are the light of the world," but "the light which lighteth every man," that very supreme wisdom itself who is God, of whom we now treat. The Son therefore is Wisdom of wisdom, namely the Father, as He is Light of light, and God of God; so that both the Father singly is light, and the Son singly is light; and the Father singly is God, and the Son singly is God: therefore the Father also singly is wisdom, and the Son singly is wisdom. And as both together are one light and one God, so both are one wisdom. But the Son is "by God made unto us wisdom, and righteousness, and sanctification;" because we turn ourselves to Him in time, that is, from some particular time, that we may remain with Him for ever. And He Himself from a certain time was "the Word made flesh, and dwelt among us."

5. On this account, then, when anything concerning wisdom is declared or narrated in the Scriptures, whether as itself speaking, or where anything is spoken of it, the Son chiefly is intimated to us. And by the example of Him who is the image, let us also not depart from Gods since we also are the Image of God: not indeed that which is equal to Him, since we are made so by the Father through the Son, and not born of the Father, as that is. And we are so, because we are enlightened with light; but that is so, because it is the light that enlightens; and which, therefore, being without pattern, is to us a pattern. For He does not imitate any one going before Him, in respect to the Father, from whom He is never separable at all, since He is the very same substance with Him from whom He is. But we by striving imitate Him who abides, and follow Him who stands still, and walking in Him, reach out towards Him; because He is made for us a way in time by His humiliation, which is to us an eternal abiding-place by His divinity. For since to pure intellectual spirits, who have not fallen through pride, He gives an example in the form of God and as equal with God and as God; so, in order that He might also give Himself as an example of returning to fallen man who on account of the uncleanness of sins and the punishment of mortality cannot see God, "He emptied Himself;" not by changing His own divinity, but by assuming our changeableness: and "taking upon Him the form of a servant" He came to us into this world," who "was in this world," because "the world was made by Him;" that He might be an example upwards to those who see God, an example downwards to those who admire man, an example to the sound to persevere, an example to the sick to be made whole, an example to those who are to die that they may not fear, an example to the dead that they may rise again, "that in all things He might have the pre-eminence." So that, because man ought not to follow any except God to blessedness, and yet cannot perceive God; by following God made man, he might follow at once Him whom he could perceive, and whom he ought to follow. Let us then love Him and cleave to Him, by charity spread abroad in our hearts, through the Holy Spirit which is given unto us. It is not therefore to be wondered at, if, on account of the example which the Image, which is equal to the Father, gives to us, in order that we may be refashioned after the image of God, Scripture, when it speaks of wisdom, speaks of the Son, whom we follow by living wisely; although the Father also is wisdom, as He is both light and God.

6. The Holy Spirit also, whether we are to call Him that absolute love which joins together Father and Son, and joins us also from beneath, that so that is not unfitly said which is written, "God is love;" how is He not also Himself wisdom, since He is light, because "God is light"? or whether after any other way the essence of the Holy Spirit is to be singly and properly named; then, too, since He is God, He is certainly light; and since He is light, He is certainly wisdom. But that the Holy Spirit is God, Scripture proclaims by the apostle, who says, "Know ye not that ye are the temple of God ?" and immediately subjoins, "And the Spirit of God dwelleth in you;" for God dwelleth in His own temple. For the Spirit of God does not dwell in the temple of God as a servant, since he says more plainly in another place, "Know ye not that your body is the temple of the Holy Ghost which is in you, and which ye have of God, and ye are not your own? For ye are bought with a great price: therefore glorify God in your body." But what is wisdom, except spiritual and unchangeable light? For yonder sun also is light, but it is corporeal; and the spiritual creature also is light, but it is not unchangeable. Therefore the Father is light, the Son is light, and the Holy Spirit is light; but together not three lights, but one light. And so the Father is wisdom, the Son is wisdom, and the Holy Spirit is wisdom, and together not three wisdoms, but one wisdom: and because in the Trinity to be is the same as to be wise, the Father, Son, and Holy Spirit, are one essence. Neither in the Trinity is it one thing to be and another to be God; therefore the Father, Son, and Holy Spirit, are one God.

Chap. 4.—How it was brought about that the Greeks speak of three hypostases, the Latins of three persons. Scripture nowhere speaks of three persons in one God.

7. For the sake, then, of speaking of things that cannot be uttered, that we may be able in some way to utter what we are able in no way to utter fully, our Greek friends have spoken of one essence, three substances; but the Latins of one essence or substance, three persons; because, as we have already said, essence usually means nothing else than substance in our language, that is, in Latin. And provided that what is said is understood only in a mystery, such a way of speaking was sufficient, in order that there might be something to say when it was asked what the three are, which the true faith pronounces to be three, when it both declares that the Father is not the Son, and that the Holy Spirit, which is the gift of God, is neither the Father nor the Son. When, then, it is asked what the three are, or who the three are, we betake ourselves to the finding out of some special or general name under which we may embrace these three; and no such name occurs to the mind, because the super- eminence of the Godhead surpasses the power of customary speech. For God is more truly thought than He is altered, and exists more truly than He is thought. For when we say that Jacob was not the same as Abraham, but that Isaac was neither Abraham nor Jacob, certainly we confess that they are three, Abraham, Isaac, and Jacob. But when it is asked what three, we reply three men, calling them in the plural by a specific name; but if we were to say three animals, then by a generic name; for man, as the ancients have defined him, is a rational, mortal animal: or again, as our Scriptures usually speak, three souls, since it is fitting to denominate the whole from the better part, that is, to denominate both body and soul, which is the whole man, from the soul; for so it is said that seventy-five souls went down into Egypt with Jacob, instead of saying so many men. Again, when we say that your horse is not mine, and that a third belonging to some one else is neither mine nor yours, then we confess that there are three; and if any one ask what three, we answer three horses by a specific name, but three animals by a generic one. And yet again, when we say that an ox is not a horse, but that a dog is neither an ox nor a horse, we speak of a three; and if any one questions us what three, we do not speak now by a specific name of three horses, or three oxen, or three dogs, because the three are not contained under the same species, but by a generic name, three animals; or if under a higher genus, three substances, or three creatures, or three natures. But whatsoever things are expressed in the plural number specifically by one name, can also be expressed genetically by one name. But all things which are generically called by one name cannot also be called specifically by one name. For three horses, which is a specific name, we also call three animals; but, a horse, and an ox, and a dog, we call only three animals or substances, which are generic names, or anything else that can be spoken generically concerning them; but we cannot speak of them as three horses, or oxen, or dogs, which are specific names; for we express those things by one name, although in the plural number, which have that in common that is signified by the name. For Abraham, and Isaac, and Jacob, have in common that which is man; therefore they are called three men: a horse also, and an ox, and a dog, have in common that which is animal; therefore they are called three animals. So three several laurels we also call three trees; but a laurel, and a myrtle, and an olive, we call only three trees, or three substances, or three natures: and so three stones we call also three bodies; but stone, and wood, and iron, we call only three bodies, or by any other higher generic name by which they can be called. Of the Father, therefore, the Son, and the Holy Spirit, seeing that they are three, let us ask what three they are, and what they have in common. For the being the Father is not common to them, so that they should be interchangeably fathers to one another: as friends, since they are so called relatively to each other, can be called three friends, because they are so mutually to each other. But this is not the case in the Trinity, since the Father only is there father; and not Father of two, but of the Son only. Neither are they three Sons, since the Father there is not the Son, nor is the Holy Spirit. Neither three Holy Spirits, because the Holy Spirit also, in that proper meaning by which He is also called the gift of God, is neither the Father nor the Son. What three therefore? For if three persons, then that which is meant by person is common to them; therefore this name is either specific or generic to them, according to the manner of speaking. But where there is no difference of nature, there things that are several in number are so expressed generically, that they can also be expressed specifically. For the difference of nature causes, that a laurel, and a myrtle, and an olive, or a horse, and an ox, and a dog, are not called by the specific name, the former of three laurels, or the latter of three oxen, but by the generic name, the former of three trees, and the latter of three animals. But here, where there is no difference of essence, it is necessary that these three should have a specific name, which yet is not to be found. For person is a generic name, insomuch that man also can be so called, although there is so great a difference between man and God.

8. Further, in regard to that very generic (generalis) word, if on this account we say three persons, because that which person means is common to them (otherwise they can in no way be so called, just as they are not called three sons, because that which son means is not common to them); why do we not also say three Gods? For certainly, since the Father is a person, and the Son a person, and the Holy Spirit a person, therefore there are three persons: since then the Father is God, and the Son God, and the Holy Spirit God, why not three Gods? Or else, since on account of their ineffable union these three are together one God, why not also one person; so that we could not say: three persons, although we call each a person singly, just as we cannot say three Gods, although we call each singly God, whether the Father, or the Son, or the Holy Spirit? Is it because Scripture does not say three Gods? But neither do we find that Scripture anywhere mentions three persons. Or is it because Scripture does not call these three, either three persons or one person (for we read of the person of the Lord, but not of the Lord as a person), that therefore it was lawful through the mere necessity of speaking and reasoning to say three persons, not because Scripture says it, but because Scripture does not contradict it: whereas, if we were to say three Gods, Scripture would contradict it, which says, "Hear, O Israel; the Lord thy God is one God?" Why then is it not also lawful to say three essences; which, in like manner, as Scripture does not say, so neither does it contradict? For if essence is a specific (specialis) name common to three, why are They not to be called three essences, as Abraham, Isaac, and Jacob are called three men, because man is the specific name common to all men? But if essence is not a specific name, but a generic one, since man, and cattle, and tree, and constellation, and angel, are called essences; why are not these called three essences, as three horses are called three animals, and three laurels are called three trees, and three stones three bodies? Or if they are not called three essences, but one essence, on account of the unity of the Trinity, why is it not the case, that on account of the same unity of the Trinity they are not to be called three substances or three persons, but one substance and one person? For as the name of essence is common to them, so that each singly is called essence, so the name of either substance or person is common to them. For that which must be understood of persons according to our usage, this is to be understood of substances according to the Greek usage; for they say three substances, one essence, in the same way as we say three persons, one essence or substance.

9. What therefore remains, except that we confess that these terms sprang from the necessity of speaking, when copious reasoning was required against the devices or errors of the heretics? For when human weakness endeavored to utter in speech to the senses of man what it grasps in the secret places of the mind in proportion to its comprehension respecting the Lord God its creator, whether by devout faith, or by any discernment whatsoever; it feared to say three essences, lest any difference should be understood to exist in that absolute equality. Again, it could not say that there were not three somewhats (tria quaedam), for it was because Sabellius said this that he fell into heresy. For it must be devoutly believed, as most certainly known from the Scriptures, and must be grasped by the mental eye with undoubting perception, that there is both Father, and Son, and Holy Spirit; and that the Son is not the same with the Father, nor the Holy Spirit the same with the Father or the Son. It sought then what three it should call them, and answered substances or persons; by which names it did not intend diversity to be meant, but singleness to be denied: that not only unity might be understood therein from the being called one essence, but also Trinity from the being called three substances or persons. For if it is the same thing with God to be (esse) as to subsist (subsistere), they were not to be called three substances, in such sense as they are not called three essences; just as, because it is the same thing with God to be as to be wise, as we do not say three essences, so neither three wisdoms. For so, because it is the same thing to Him to be God as to be, it is not right to say three essences, as it is not right to say three Gods. But if it is one thing to God to be, another to subsist, as it is one thing to God to be, another to be the Father or the Lord (for that which He is, is spoken in respect to Himself, but He is called Father in relation to the Son, and Lord in relation to the creature which serves Him); therefore He subsists relatively, as He besets relatively, and bears rule relatively: so then substance will be no longer substance, because it will be relative. For as from being, He is called essence, so from subsisting, we speak of substance. But it is absurd that substance should be spoken relatively, for everything subsists in respect to itself; how much more God?

Chap. 5.—In God, substance is spoken improperly, essence properly.

10. If, however, it is fitting that God should be said to subsist—(For this word is rightly applied to those things, in which as subjects those things are, which are said to be in a subject, as color or shape in body. For body subsists, and so is substance; but those things are in the body, which subsists and is their subject, and they are not substances, but are in a substance: and so, if either that color or that shape ceases to be, it does not deprive the body of being a body, because it is not of the being of body, that it should retain this or that shape or color; therefore neither changeable nor simple things are properly called substances.)—If, I say, God subsists so that He can be properly called a substance, then there is something in Him as it were in a subject, and He is not simple, i.e. such that to Him to be is the same as is anything else that is said concerning Him in respect to Himself; as, for instance, great, omnipotent, good, and whatever of this kind is not unfitly said of God. But it is an impiety to say that God subsists, and is a subject in relation to His own goodness, and that this goodness is not a substance or rather essence, and that God Himself is not His own goodness, but that it is in Him as in a subject. And hence it is clear that God is improperly called substance, in order that He may be understood to be, by the more usual name essence, which He is truly and properly called; so that perhaps it is right that God alone should be called essence. For He is truly alone, because He is unchangeable; and declared this to be His own name to His servant Moses, when He says, "I a
