Who is it precisely who determined that these books oughtn't be included in the Bible? ;-) That reminds me of kids who post here, asking for help on term papers.
Or my kids who ask simple questions.
Answer is "Look it up."
Thing about this question, it takes a little digging to go past secondary sources; or at least compare what authority and reference is cited for a claim.
I did the work, and the canon of Holy Scripture was not a project of the Apostles.
There may be an eager beaver who will post links, but my opinion is that folks need to learn how to learn.
And "Bibles," complete collections of the Scriptures were rare in antiquity. Since it is an anthology of many different books, probably most Christians never saw the complete works. Not until the 13th Century were Larin Bibles compressed into the size of a book that could be carried around. They were hand-written on very thin parchment. Franciscans and Dominicans carried it around in their pockets and preached from them.
