I personally have no idea how or why certain books, chapters, verses etc. were selected for the New Testament. I trust that those who did, knew what they were doing.
I also do not know which translation is best. My Grandfather attended Southern Baptist Seminary in Louisville back in the early 1900s. He was an absolute genius.
I remember his telling me one time that the King James Version of the Bible was an excellent translation.
Never liked Book of John—Makes Jesus all God—very unlike other Gospels. I also like much of the Book of Thomas—that was not included. The Hymm of the Shepard —also not included is good—as well as the Coptic Book of Enoch (used by Jude). The Bible has many elements—its a library of books—inspired by God but organized by man.
Now I will comment, as the first and second threads on this have been commented on in full.
If there was no inspiration from God in compiling the scriptures (i.e. placing the 39 Old Testament and 27 New Testament books together and binding them in one book) and there is only inspired scripture - but, again, no inspiration in/for compilation - then did those councils and groups of men ascend to the level of the Absolute and Absolute Being and then become incapable of committing error when compiling them?
If so, A.) how then do we account for the earliest Greek manuscripts (Codex Sinaiticus, Alexandrinus, and Vaticanus) each being different from the other (even when barring pages that were lost) and being different from each other in the realm of books that are there? And how do we account for B.) the Clermont List and the Muratorian Fragment being different from each other?
I ask this because the scriptures didn’t place themselves into a bound Codex, List, etcetera, and God did not send down a compilation of 39 OT and 27 NT bound books and say “Here are your inspired scriptures to read.”
