For of the Law the books of Moses are the first five, Genesis, Exodus, Leviticus, Numbers, Deuteronomy. And next, Joshua the son of Nave , and the book of Judges, including Ruth, counted as seventh. And of the other historical books, the first and second books of the Kings are among the Hebrews one book; also the third and fourth one book. And in like manner, the first and second of Chronicles are with them one book; and the first and second of Esdras are counted one. Esther is the twelfth book; and these are the Historical writings. But those which are written in verses are five, Job, and the book of Psalms, and Proverbs, and Ecclesiastes, and the Song of Songs, which is the seventeenth book. And after these come the five Prophetic books: of the Twelve Prophets one book, of Isaiah one, of Jeremiah one, including Baruch and Lamentations and the Epistle [the epistle of Jeremiah is now included in the Catholic Bible in Baruch but I think the Orthodox Churches have it as a separate book]; then Ezekiel, and the Book of Daniel, the twenty-second of the Old Testament.
Then of the New Testament there are the four Gospels only, for the rest have false titles and are mischievous. The Manichæans also wrote a Gospel according to Thomas, which being tinctured with the fragrance of the evangelic title corrupts the souls of the simple sort. Receive also the Acts of the Twelve Apostles; and in addition to these the seven Catholic Epistles of James, Peter, John, and Jude; and as a seal upon them all, and the last work of the disciples, the fourteen Epistles of Paul. But let all the rest be put aside in a secondary rank. [26 books, Revelation not included]
via CHURCH FATHERS: Catechetical Lecture 4 (Cyril of Jerusalem).
St. Cyril lived in the 300s and wrote these catechetical lectures around 350 AD. He includes the deuterocanonical book Baruch in his OT canon but not the other deuteros and omits the NT book of Revelation from his canon.
What is fascinating about his canon is that it demonstrates that even as late as the mid-300s, the canon was not definitively settled: There were conflicting canons being proposed and used and not until later in this century would the full canon as we know it today be agreed upon within Christ’s Church and approved by the Pope.
