<P> Before the fifth century, the Christian writings that were then under discussion for inclusion in the canon but had not yet been accepted were classified in a group known as the ancient antilegomenae . These were all candidates for the New Testament and included several books which were eventually accepted, such as: The Epistle to the Hebrews, 2 Peter, 3 John and the Revelation of John (Apocalypse). None of those accepted books can be considered Apocryphal now, since all Christendom accepts them as canonical . Of the uncanonized ones, the Early Church considered some heretical but viewed others quite well . Some Christians, in an extension of the meaning, might also consider the non-heretical books to be "apocryphal" along the manner of Martin Luther: not canon, but useful to read . This category includes books such as the Epistle of Barnabas, the Didache, and The Shepherd of Hermas which are sometimes referred to as the Apostolic Fathers . The Gnostic tradition was a prolific source of apocryphal gospels . While these writings borrowed the characteristic poetic features of apocalyptic literature from Judaism, Gnostic sects largely insisted on allegorical interpretations based on a secret apostolic tradition . With them, these apocryphal books were highly esteemed . A well - known Gnostic apocryphal book is the Gospel of Thomas, the only complete text of which was found in the Egyptian town of Nag Hammadi in 1945 . The Gospel of Judas, a Gnostic gospel, also received much media attention when it was reconstructed in 2006 . </P> <P> Roman Catholics and Orthodox Christians as well as Protestants generally agree on the canon of the New Testament, see Development of the New Testament canon . The Ethiopian Orthodox have in the past also included I & II Clement and Shepherd of Hermas in their New Testament canon . </P> <P> The List of Sixty, dating to around the 7th century, lists the sixty books of the Bible . The unknown author also lists several apocryphal books that are not included amongst the sixty .
