The Bible?

That is a great question. A few months back the History Channel had a great show about this very question.

From information I received from that source and other books I have read, a group of men were assembled and assigned the task of putting the books of the bible together.

There were great discussion as to which books would comprise the bible and which would not. Like anything else the committee selected the books after great deliberation and much discussion.

There was a great controversy over the books that were left out of the bible, apparently more so, than the books that finally comprised the bible.

There is, and I can't remember now, a large volume of books that were considered to become apart of the bible at some library in one of the middle western countries.

I hope this has been of some use to you, good luck.

"FIGHT ON"

The earliest Christians were not a separate religion, but a sect of the Jewish faith. Jesus himself quotes quite a bit from the Jewish scriptures, and claimed he came not to overthrow the old law, but to complete it. Nobody chose to stick the testaments together, but rather the Christian believes that the New Testament is an extension of the Jewish scripture.

first of all, Jews didn't wrote the Old Testament

Jews didn't write the Old Testament nor do they refer to it as such. It is the Torah and it was given at Sinai. Christians much to the disdain of Paul stuck them together.

It was the people from the Church's that decided what went into the the Bible.
