How many books are there in the entire Bible?

Answer 1

66: 39 in the Old Testament, 27 in the New Testament for the Protestant Bible.

There are 73 books in Holy Christian Scripture (Bible) in the Catholic and Orthodox churches. The Gutenberg Bible, printed over time between 1452 and 1453 contains all 73 books of Holy Christian Scripture. During the Protestant movement, various Protestant denominations removed 7 books from The Bible, which are called deuterocanonical or apocrypha. Some allege that the Council of Trent "added" the 7 books. This claim is considered false by the Catholic church. The Council of Trent occurred in 1545, almost 100 years after the printing of the Gutenberg Bible. The Council of Trent reaffirmed the authenticity ("canonicity") of the 7 books removed by sects of the Protestant movement.
