The Didache (Teaching/The Lord's Teaching Through the Twelve Apostles to the Nations)
Composed in the late 1st century or early 2nd century, the Didache was a work of great authority in the early Church, one read in the liturgy although it would ultimately be counted among the Scriptures. It is noted for its discourse on the way of death and the way of life.
Didache, Chap. IX, 1-5, Thanksgiving (Eucharist). Now concerning the Thanksgiving (Eucharist), thus give thanks. First, concerning the cup: We thank thee, our Father, for the holy vine of David Thy servant, which Thou madest known to us through Jesus Thy Servant; to Thee be the glory for ever. And concerning the broken bread: We thank Thee, our Father, for the life and knowledge which Thou madest known to us through Jesus Thy Servant; to Thee be the glory for ever. Even as this broken bread was scattered over the hills, and was gathered together and became one, so let Thy Church be gathered together from the ends of the earth into Thy kingdom; for Thine is the glory and the power through Jesus Christ for ever. But let no one eat or drink of your Thanksgiving (Eucharist), but they who have been baptized into the name of the Lord; for concerning this also the Lord hath said, Give not that which is holy to the dogs.
Chap. XIV, 1-3. But every Lord’s day do ye gather yourselves together, and break bread, and give thanksgiving after having confessed your transgressions, that your sacrifice may be pure. But let no one that is at variance with his fellow come together with you, until they be reconciled, that your sacrifice may not be profaned. For this is that which was spoken by the Lord: In every place and time offer to me a pure sacrifice; for I am a great King, saith the Lord, and my name is wonderful among the nations.
St. Ignatius of Antioch (c.50-c.110 A.D.)
Bishop of Antioch in Syria, St. Ignatius, along with St. Polycarp, were disciples of St. John at Smyrna, and thus considered to bridge the era of the Apostles and the era of the Fathers of the Church. Arrested and taken to Rome for judgment during the persecution of the Emperor Trajan, in imitation of his spiritual father John, he wrote 7 letters to the churches, which together cover the challenges of the Churches in his day.
To the Romans, Ch. 7. Do not speak of Jesus Christ, and yet prefer this world to Him . . . I have no delight in corruptible food, nor in the pleasures of this life. I desire the bread of God, the heavenly bread, the bread of life, which is the flesh of Jesus Christ, the Son of God, who became afterwards of the seed of David and Abraham; and I desire the drink, namely His blood, which is incorruptible love and eternal life.
To the Philadelphians Ch. 4. I have confidence of you in the Lord, that ye will be of no other mind. Wherefore I write boldly to your love, which is worthy of God, and exhort you to have but one faith, and one [kind of] preaching, and one Eucharist. For there is one flesh of the Lord Jesus Christ; and His blood which was shed for us is one; one loaf also is broken to all [the communicants], and one cup is distributed among them all: there is but one altar for the whole Church, and one bishop, with the presbytery and deacons, my fellow-servants. Since, also, there is but one unbegotten Being, God, even the Father; and one only-begotten Son, God, the Word and man; and one Comforter, the Spirit of truth; and also one preaching, and one faith, and one baptism; and one Church which the holy apostles established from one end of the earth to the other by the blood of Christ, and by their own sweat and toil . . . .
To the Smyrnaeans Ch. 7. They (the Gnostics) abstain from the Eucharist and from prayer, because they confess not the Eucharist to be the flesh of our Savior Jesus Christ, which suffered for our sins, and which the Father, of His goodness, raised up again. Those, therefore, who speak against this gift of God, incur death in the midst of their disputes. But it were better for them to treat it with respect, that they also might rise again.
St. Justin the Martyr (c. 100 - 165 A.D.)
St. Justin was born in the Holy Land, likely in Flavia Neopolis, today Nablus, a city north of Jerusalem. Converting at about 30 years of age he preached in Asia Minor and in Rome. He is most noted for his apologias, defenses of the faith, written to the Emperor Antoninus Pius, considered one of the better, more just, emperors, and to a Jew named Trypho. Together with St. Irenaeus’ Against Heresies, they give a window on the faith and its theological explanation in the mid to late 2nd century.
First Apology, Ch. LXVI. And this food is called among us Εὐχαριστία [the Eucharist], of which no one is allowed to partake but the man who believes that the things which we teach are true, and who has been washed with the washing that is for the remission of sins, and unto regeneration, and who is so living as Christ has enjoined. For not as common bread and common drink do we receive these; but in like manner as Jesus Christ our Saviour, having been made flesh by the Word of God, had both flesh and blood for our salvation, so likewise have we been taught that the food which is blessed by the prayer of His word, and from which our blood and flesh by transmutation are nourished, is the flesh and blood of that Jesus who was made flesh. For the apostles, in the memoirs composed by them, which are called Gospels, have thus delivered unto us what was enjoined upon them; that Jesus took bread, and when He had given thanks, said, “This do ye in remembrance of Me, this is My body;” and that, after the same manner, having taken the cup and given thanks, He said, “This is My blood;” and gave it to them alone. Which the wicked devils have imitated in the mysteries of Mithras, commanding the same thing to be done. For, that bread and a cup of water are placed with certain incantations in the mystic rites of one who is being initiated, you either know or can learn.
Dialogue with Trypho. “And the offering of fine flour, sirs,” I said, “which was prescribed to be presented on behalf of those purified from leprosy, was a type of the bread of the Eucharist, the celebration of which our Lord Jesus Christ prescribed, in remembrance of the suffering which He endured on behalf of those who are purified in soul from all iniquity, in order that we may at the same time thank God for having created the world, with all things therein, for the sake of man, and for delivering us from the evil in which we were, and for utterly overthrowing principalities and powers by Him who suffered according to His will.
Hence God speaks by the mouth of Malachi, one of the twelve [prophets], as I said before, about the sacrifices at that time presented by you: ‘I have no pleasure in you, saith the Lord; and I will not accept your sacrifices at your hands: for, from the rising of the sun unto the going down of the same, My name has been glorified among the Gentiles, and in every place incense is offered to My name, and a pure offering: for My name is great among the Gentiles, saith the Lord: but ye profane it.’ [So] He then speaks of those Gentiles, namely us, who in every place offer sacrifices to Him, i.e., the bread of the Eucharist, and also the cup of the Eucharist, affirming both that we glorify His name . . .
St. Clement of Alexandria, Instructor, 1.6 (c. 150 - 216 A.D.)
(On the Lord addressing us as children). The Word is all to the child, both father and mother and tutor and nurse. “Eat ye my flesh,” He says, “and drink my blood.” Such is the suitable food which the Lord ministers, and He offers His flesh and pours forth His blood, and nothing is wanting for the children’s growth. O amazing mystery! We are enjoined to cast off the old and carnal corruption, as also the old nutriment, receiving in exchange another new regimen, that of Christ, receiving Him if we can, to hide Him within; and that, enshrining the Saviour in our souls, we may correct the affections of our flesh.
St. Cyprian of Carthage, (c. 200 - 258 A.D.)
Treatise IV, On the Lord’s Prayer, 18. [W]e ask and say, “Give us this day our daily bread.” And this may be understood both spiritually and literally, because either way of understanding it is rich in divine usefulness to our salvation. For Christ is the bread of life; and this bread does not belong to all men, but it is ours. And according as we say, “Our Father,” because He is the Father of those who understand and believe; so also we call it “our bread,” because Christ is the bread of those who are in union with His body. And we ask that this bread should be given to us daily, that we who are in Christ, and daily5 receive the Eucharist for the food of salvation, may not, by the interposition of some heinous sin, by being prevented, as withheld and not communicating, from partaking of the heavenly bread, be separated from Christ’s body, as He Himself predicts, and warns, “I am the bread of life which came down from heaven.
Letters 62, To Caecilius, On the Sacrament of the Cup of the Lord, 4. Also in the priest Melchizedek we see prefigured the sacrament of the sacrifice of the Lord, according to what divine Scripture testifies, and says, “And Melchizedek, king of Salem, brought forth bread and wine.” Now he was a priest of the most high God, and blessed Abraham. And that Melchizedek bore a type of Christ, the Holy Spirit declares in the Psalms, saying from the person of the Father to the Son: “Before the morning star I begat Thee; Thou art a priest forever, after the order of Melchizedek;” which order is assuredly this coming from that sacrifice and thence descending; that Melchizedek was a priest of the most high God; that he offered wine and bread; that he blessed Abraham. For who is more a priest of the most high God than our Lord Jesus Christ, who offered a sacrifice to God the Father, and offered that very same thing which Melchizedek had offered, that is, bread and wine, to wit, His body and blood?
Ibid., 14. For if in the sacrifice which Christ offered none is to be followed but Christ, assuredly it behooves us to obey and do that which Christ did, and what He commanded to be done, since He Himself says in the Gospel, “If ye do whatsoever I command you, henceforth I call you not servants, but friends.” . . . Moreover, in another place He establishes it, saying, “Whosoever shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven.” But if we may not break even the least of the Lord’s commandments, how much rather is it forbidden to infringe such important ones, so great, so pertaining to the very sacrament of our Lord’s passion and our own redemption, or to change it by human tradition into anything else than what was divinely appointed! For if Jesus Christ, our Lord and God, is Himself the chief priest of God the Father, and has first offered Himself a sacrifice to the Father, and has commanded this to be done in commemoration of Himself, certainly that priest truly discharges the office of Christ, who imitates that which Christ did; and he then offers a true and full sacrifice in the Church to God the Father, when he proceeds to offer it according to what he sees Christ Himself to have offered.
