A number of books are not considered to be part of the Bible by Protestant Christians, but are by other denominations - these books are referred to as [[Apocrypha|apocryphal literature]].
====Formation of the Bible / [[Biblical Canon]]====
Though the Early Church used the Old Testament, the apostles did not otherwise leave a defined set of new scriptures; instead the New Testament developed over time. By the fourth century the books included by today's Protestants in the [[Bible]] were roughly agreed upon.
