The number of New Testament parts of the Bible is relatively consistent, and Catholicism, Orthodox Christianity and Protestantism all recognize 27 volumes.

The canon bibliography of the New Testament was officially confirmed at the Carthage Conference held in 397 AD. It was originally lost, and the earliest transcript fragments found now were copied in the 2nd century AD. After the text of the New Testament was basically finalized in the 4th century, manuscripts from Egypt, Alexandria and Syria became popular. At present, the earliest preserved Greek Bible manuscripts are from the 4th century to the 5th century, among which the most famous are the Sinai manuscript, Vatican manuscript and Alexander manuscript.
