2. But since we have made mention of heretics as dead, but of ourselves as possessing the Divine Scriptures for salvation; and since I fear lest, as Paul wrote to the Corinthians, some few of the simple should be beguiled from their simplicity and purity, by the subtilty of certain men, and should henceforth read other books—those called apocryphal—led astray by the similarity of their names with the true books; I beseech you to bear patiently, if I also write, by way of remembrance, of matters with which you are acquainted, influenced by the need and advantage of the Church.
3. In proceeding to make mention of these things, I shall adopt, to commend my undertaking, the pattern of Luke the evangelist, saying on my own account, Forasmuch as some have taken in hand to reduce into order for themselves the books termed Apocryphal, and to mix them up with the divinely inspired Scripture, concerning which we have been fully persuaded, as they who from the beginning were eye-witnesses and ministers of the Word, delivered to the Fathers; it seemed good to me also, having been urged thereto by true brethren, and having learned from the beginning, to set before you the books included in the Canon, and handed down, and accredited as divine; to the end that anyone who has fallen into error may condemn those who have led them astray; and that he who has continued steadfast in purity may again rejoice, having these things brought to his remembrance.
4. There are, then, of the Old Testament, twenty-two books in number; for, as I have heard, it is handed down that this is the number of the letters among the Hebrews; their respective order and names being as follows. The first is Genesis, then Exodus, next Leviticus, after that Numbers, and then Deuteronomy. Following these there is Joshua the son of Nun, then Judges, then Ruth. And again, after these four books of Kings, the first and second 1being reckoned as one book, and so likewise the third and fourth 2 as one book. And again, the first and second of the Chronicles are reckoned as one book. Again Ezra, the first and second 3 are similarly one book. After these there is the book of Psalms, then the Proverbs, next Ecclesiastes, and the Song of Songs. Job follows, then the Prophets, the Twelve [minor prophets] being reckoned as one book. Then Isaiah, one book, then Jeremiah with Baruch, Lamentations and the Epistle, one book; afterwards Ezekiel and Daniel, each one book. Thus far constitutes the Old Testament.
5. Again, it is not tedious to speak of the books of the New Testament. These are: the four Gospels, according to Matthew, Mark, Luke, and John. After these, The Acts of the Apostles, and the seven epistles called Catholic: of James, one; of Peter, two, of John, three; after these, one of Jude. In addition, there are fourteen epistles of Paul the apostle, written in this order: the first, to the Romans; then, two to the Corinthians; after these, to the Galatians; next, to the Ephesians, then, to the Philippians; then, to the Colossians; after these, two of the Thessalonians; and that to the Hebrews; and again, two to Timothy; one to Titus; and lastly, that to Philemon. And besides, the Revelation of John.
6. These are the fountains of salvation, that he who thirsts may be satisfied with the living words they contain. In these alone the teaching of godliness is proclaimed. Let no one add to these; let nothing be taken away from them. For concerning these the Lord put to shame the Sadducees, and said, Ye do err, not knowing the Scriptures. And he reproved the Jews, saying, Search the Scriptures, for these are they that testify of me.
7. But for the sake of greater exactness I add this also, writing under obligation, as it were. There are other books besides these, indeed not received as canonical but having been appointed by our fathers to be read to those just approaching and wishing to be instructed in the word of godliness: Wisdom of Solomon, Wisdom of Sirach, Esther, Judith, Tobit, and that which is called the Teaching of the Apostles, and the Shepherd. But the former, my brethren, are included in the Canon, the latter being merely read; nor is there any place a mention of secret writings. But such are the invention of heretics, who indeed write them whenever they wish, bestowing upon them their approval, and assigning to them a date, that so, using them as if they were ancient writings, they find a means by which to lead astray the simple-minded.
