There are 2 major divisions of the Bible...the Hebrew Scriptures and what Christians refer to as the New Testament. The Bible was written over a 1,500+ year span by more than 40 different authors from all parts of life so to speak ie: Moses was a political leader trained at the universities of Egyptavid was a Shepherd,musician & King:Joshua was a military general:Nehemiah was a palace official to a pagan kinganiel was a pm:Luke was a Physician & historian:Paul was a rabbi etc..those are just a few. The Bible was also written in different places ie:The desert,a dungeon,a palace,a prison etc....There are 3 languages:Hebrew,Greek and a few short sections in Aramic which was "the common language" of Jesus' time. The Bible was written on 3 different continents at different times..The Bible is much more than a historical record..not saying parts are not history..they are but other parts of the Bible are poetry,proverbs,personal correspondence (yes its true),memoirs,law,prophecy,biography,autobiography ,parables & allegory..so I understand about people saying its mans word but i don't agree..considering that the Old Testament supports the Hebrew Scriptures as we know them today..they were collected & recognized long before Constantine possibly as early as the 4th century b.c. and for certain no later than 150 b.c. Malachi was written around 450 to 430 b.c. and Chronicles was written no later than 400 b.c. my point being that the books of the Old Testament were collected and translated into Greek NOT by the Vatican..not by Constantine & not even early Christians but more than a hundred years before Jesus' birth by a consensus of generations of Jewish rabbis and scholars..so in my view of the word definitive..that would be it.
