Cyril of Jerusalem on the Canon - From his Catechetical Lectures, iv. 33-37, about A.D. 350.
33. Now these the divinely-inspired Scriptures of both the Old and the New Testament teach us. For the God of the two Testaments is One, Who in the Old Testament foretold the Christ Who appeared in the New; Who by the Law and the Prophets led us to Christ's school. For before faith came, we were kept in ward under the law, and, the law hath been our tutor to bring us unto Christ. 1 And if ever thou hear any of the heretics speaking evil of the Law or the Prophets, answer in the sound of the Saviour's voice, saying, Jesus came not to destroy the Law, but to fulfil it. 2 Learn also diligently, and from the Church, what are the books of the Old Testament, and what those of the New. And, pray, read none of the apocryphal writings: 3 for why dost thou, who knowest not those which are acknowledged among all, trouble thyself in vain about those which are disputed? Read the Divine Scriptures, the twenty-two books of the Old Testament, these that have been translated by the Seventy-two Interpreters. 4
Council of Laodicea (about A.D. 363).
It is proper to recognize as many books as these: of the Old Testament, 1. the Genesis of the world; 2. the Exodus from Egypt; 3. Leviticus; 4. Numbers; 5. Deuteronomy; 6. Joshua the son of Nun; 7. Judges and Ruth; 8. Esther; 9. First and Second Kings [i.e. First and Second Samuel]; 10. Third and Fourth Kings [i.e. First and Second Kings]; 11. First and Second Chronicles; 12. First and Second Ezra [i.e. Ezra and Nehemiah]; 13. the book of one hundred and fifty Psalms; 14. the Proverbs of Solomon; 15. Ecclesiastes; 16. Song of Songs; 17. Job; 18. the Twelve [minor] Prophets; 19. Isaiah; 20. Jeremiah and Baruch, Lamentations and the Epistle [of Jeremiah]; 21. Ezekiel; 22. Daniel.
AD 400 - Jerome translates the Bible from Hebrew and Greek into Latin (called the "Vulgate"). He knows that the Jews have only 39 books, and he wants to limit the OT to these; the 7 he would leave out (Tobit, Judith, 1 Maccabees, 2 Maccabees, Wisdom of Solomon, Sirach [or "Ecclesiasticus"], and Baruch--he calls "apocrypha," that is, "hidden books." But Pope Damasus wants all 46 traditionally-used books included in the OT, so the Vulgate has 46.
So your hard facts fall short, here is evidence in two places of the use of a smaller bible - based upon the Jewish canon from Jamiah in the 1st/early 2d century.
Cyril was a Catholic Bishop, who by himself, had no authority to set the canon.
The Council of Laodicea did not include Revelation in the NT canon and included the Book of Baruch in the OT canon. No 66 book Bible here, but i do give you credit for giving authority to a Council of Catholic Bishops!
Jerome’s Vulgate was not a 66 book Bible, but again i give you credit for trying to cite a Catholic as authoritative.
again, my facts stand unrefuted, there was not a 66 book Bible before the 16th century.
just read Cyril in total and he also did not include Revelation in the NT list of books.
again, no 66 books.
35. Of these read the two and twenty books, but have nothing to do with the apocryphal writings. Study earnestly these only which we read openly in the Church. Far wiser and more pious than thyself were the Apostles, and the bishops of old time, the presidents of the Church who handed down these books. Being therefore a child of the Church, trench[6] thou not upon its statutes. And of the Old Testament, as we have said, study the two and twenty books, which, if thou art desirous of learning, strive to remember by name, as I recite them. For of the Law the books of Moses are the first five, Genesis, Exodus, Leviticus, Numbers, Deuteronomy. And next, Joshua the son of Nave[7], and the book of Judges, including Ruth, counted as seventh. And of the other historical books, the first and second books of the Kings[8] 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[9]; then Ezekiel, and the Book of Daniel, the twenty-second of the Old Testament.

uh oh, Cyril included Baruch in the canon, the same as the Council of Laodicea.
