The larger point, that the Bible is really a library, I think anyone familiar with it would agree with regardless of how many "books" they say the library contains.
I’m a member at this site: https://www.christianforums.com/threads/the-bible-73-or-66-books.8006170/
And I like this from the thread I linked:
“But of course we are not talking about Catholic books or even books written by NT Christians in the first century - we are talking about Jewish books... we are talking about the Hebrew Bible and whether the content of it which we have in 39 books... should have been 39 or 50. The Jews say 39 and that was the Bible that Christ had - the one that was kept in the Temple in Jerusalem.
“As Josephus points out the Jews had not changed their Bible in over 300 years. IT is not the Bible of Christ’s day to add 11 books to the Hebrew Bible.
“They ‘knew’ about the 11 books - but they did not add them to the scriptures. The canonized set that had been fixed for over 3 centuries.”
The larger point, that the Bible is really a library, I think anyone familiar with it would agree with regardless of how many “books” they say the library contains.
i.e. the stuff in red is much more critical than III John.
