New Testament apocrypha
Various books that were never canonized by any church, but are known to have existed in antiquity, are similar to the New Testament and often claim apostolic authorship, are known as the New Testament apocrypha. Some of these writings have been cited as scripture by early Christians, but since the fifth century a widespread consensus has emerged limiting the New Testament to the 27 books of the modern canon. Thus Roman Catholic, Eastern Orthodox and Protestant churches generally do not view these New Testament apocrypha as part of the Bible.
