Athanasius (NT Canon/AD 367)

“Since, however, we have spoken of the heretics as dead but of ourselves as possessors of the divine writings unto salvation, and since I am afraid that -- as Paul has written to the Corinthians [2 Cor. 11:3] -- some guileless persons may be led astray from their purity and holiness by the craftiness of certain men and begin thereafter to pay attention to other books, the so-called apocryphal writings, being deceived by their possession of the same names as the genuine books, I therefore exhort you to patience when, out of regard to the Church's need and benefit, I mention in my letter matters with which you are acquainted. It being my intention to mention these matters, I shall, for the commendation of my venture, follow the example of the evangelist Luke and say [cf. Luke 1:1-4]: Since some have taken in hand to set in order for themselves the so-called apocrypha and to mingle them with the God-inspired scripture, concerning which we have attained to a sure persuasion, according to what the original eye-witness and ministers of the word have delivered unto our fathers, I also, having been urged by true brethren and having investigated the matter from the beginning, have decided to set forth in order the writings that have been put in the canon, that have been handed down and confirmed as divine, in order that every one who has been led astray may condemn his seducers, and that every one who has remained stainless may rejoice, being again reminded of that.”

“Continuing, I must without hesitation mention the scriptures of the New Testament; they are the following: the four Gospels according to Matthew, Mark, Luke, and John, after them the Acts of the Apostles and the seven so called catholic epistles of the apostles -- namely, one of James, two of Peter, then three of John and after these one of Jude. In addition there are fourteen epistles of the apostle Paul written in the following order: the first to the Romans, then two to the Corinthians and then after these the one to the Galatians, following it the one to the Ephesians, thereafter the one to the Philippians and the one to the Colossians and two to the Thessalonians and the epistle to the Hebrews and then immediately two to Timothy , one to Titus and lastly the one to Philemon. Yet further the Revelation of John These are the springs of salvation, in order that he who is thirsty may fully refresh himself with the words contained in them. In them alone is the doctrine of piety proclaimed. Let no one add anything to them or take anything away from them... But for the sake of greater accuracy I add, being constrained to write, that there are also other books besides these, which have not indeed been put in the canon, but have been appointed by the Fathers as reading-matter for those who have just come forward and which to be instructed in the doctrine of piety: the Wisdom of Solomon, the Wisdom of Sirach, Esther, Judith, Tobias, the so-called Teaching [Didache] of the Apostles, and the Shepherd. And although, beloved, the former are in the canon and the latter serve as reading matter, yet mention is nowhere made of the apocrypha; rather they are a fabrication of the heretics, who write them down when it pleases them and generously assign to them an early date of composition in order that they may be able to draw upon them as supposedly ancient writings and have in them occasion to deceive the guileless.”
