How Many Books Are In the New Testament?

The New Testament comprises about one-third of the Bible. While it’s a continuation of the story that started in the Old Testament, it reveals the era of the New Covenant that Jesus of Nazareth inaugurated through his death and resurrection. The New Testament contains books belonging to genres like biography, epistles or letters, historical accounts, and apocalyptic literature.

The New Testament contains 27 books. First, there are four Gospels, which read like biographies of Jesus Christ. Acts is next and tells of the history of the early church. Then, there are 21 letters, 13 of which the Apostle Paul wrote. Lastly, there is one book of apocalyptic literature, Revelation.

Why Are There 27 New Testament Books?

Bible scholar Bill Arnold writes, “The twenty-seven New Testament writings are the ones that earned the recognition of early Christians as having been inspired by God and given to the church ‘for teaching, for reproof, for correction, and for training in righteousness’ (2 Tm 3:16, NRSV).” [1]
