The paternity of one of those New Testament Letters known as "catholic," since they are not addressed to a specific local Church but intended for a far wider circle, has been attributed to Jude Thaddaeus. Actually, it is addressed "to those who are called, beloved in God the Father and kept for Jesus Christ" (v. 1).
A major concern of this writing is to put Christians on guard against those who make a pretext of God's grace to excuse their own licentiousness and corrupt their brethren with unacceptable teachings, introducing division within the Church "in their dreamings" (v. 8).
This is how Jude defines their doctrine and particular ideas. He even compares them to fallen angels and, mincing no words, says that "they walk in the way of Cain" (v. 11).
Furthermore, he brands them mercilessly as "waterless clouds, carried along by winds; fruitless trees in late autumn, twice dead, uprooted; wild waves of the sea, casting up the foam of their own shame; wandering stars for whom the nether gloom of darkness has been reserved for ever" (vv. 12-13).
Today, perhaps, we are no longer accustomed to using language that is so polemic, yet that tells us something important. In the midst of all the temptations that exist, with all the currents of modern life, we must preserve our faith's identity. Of course, the way of indulgence and dialogue, on which the Second Vatican Counsel happily set out, should certainly be followed firmly and consistently.
But this path of dialogue, while so necessary, must not make us forget our duty to rethink and to highlight just as forcefully the main and indispensable aspects of our Christian identity. Moreover, it is essential to keep clearly in mind that our identity requires strength, clarity, and courage in light of the contradictions of the world in which we live.
Thus, the text of the Letter continues: "But you, beloved" - he is speaking to all of us -, "build yourselves up on your most holy faith; pray in the Holy Spirit; keep yourselves in the love of God; wait for the mercy of our Lord Jesus Christ unto eternal life. And convince some, who doubt..." (vv. 20-22).
The Letter ends with these most beautiful words: "To him who is able to keep you from falling and to present you without blemish before the presence of his glory with rejoicing, to the only God, our Saviour through Jesus Christ our Lord, be glory, majesty, dominion and authority, before all time and now and for ever. Amen" (vv. 24-25).
It is easy to see that the author of these lines lived to the full his own faith, to which realities as great as moral integrity and joy, trust and lastly praise belong, since it is all motivated solely by the goodness of our one God and the mercy of our Lord Jesus Christ.
