Answer 2

The combination of the Old Testament and the New Testament to form the Christian Bible took place during the early centuries of the Christian church. The process of canonization was gradual and complex, with various councils and discussions held to determine which texts would be included in the final version of The Bible. By the fourth century, the Christian Bible had largely taken the form it has today, with the Old Testament and New Testament books being recognized as sacred scripture for Christians.
