In another post you stated that there is a lot of evidence that by AD 70 the canon was complete. The complication is that there is a difference between being written and being recognized as scripture. The Church decided what books were in the Bible and what ones were left out. The Bible itself has no list of books that belong in the Bible so I would ask you your own question. Show me proof from the Bible what books belong in the Bible.
There is internal evidence within the Bible that verifies the cannon. Pastor Cascione's research in the Greek and Hebrew manuscripts shows a unifying pattern underlying the entire Bible that is not found in the extra-Biblical writings. See his book,
In Search of the Biblical Order -- Patterns in the Text Affirming Divine Authorship from Revelation to Genesis
I will review the rest of your message later.
Besides the above proof, this interesting book makes the case for internal proof:
The Canon of Scripture: A Presuppositional Study
"In this book, Dr. Kayser proves the canonicity of each of the 66 books of the Bible using the Bible itself. He defends and demonstrates the Protestant doctrine that “only God can identify His word,” and did so through the very prophets who gave us the Scriptures. The Bible’s self-referential statements are sufficient to completely settle the question of canonicity. There can be no higher authority by which Scripture is judged than itself, or the Scripture would cease to be the highest authority."Further, see footnote 78 from Dr. Kayser:
78 Leon Morris summarizes the overwhelming historical evidence when he says,
The church never attempted to create or confer canonicity. The decrees of the councils dealing with the matter, never run in the form: ‘This Council decrees that henceforth such and such books are to be canonical.’ The decrees rather run in the form: ‘This Council declares that these are the books which have always been held to be canonical.’ The Synod always contents itself with saying which books are already accepted as canonical. It often speaks of the accepted books as those which have been ‘handed down.’ It never attempts to confer canonicity on a book which lacked it, nor to remove from the list a book which was agreed to have had it… Canonicity is something in the book itself, something that God has given it, not a flavored status the church confers upon it. The church made no attempt to do more than to recognize canonicity and it could do no more. (Leon Morris, “The Canon of the New Testament,” Encyclopedia of Christianity, volume 2, edited by G.G. Cohen, Marshallton, Delaware: The National Foundation for Christian Education, 1968, pp. 337-338, as quoted by Dr. Robert Fugate in his doctoral thesis: The Bible: God’s Words to You (unpublished doctoral thesis at Whitefield Theological Seminary, 2008))
