New Testament apocrypha and produce new translations. The texts of the Nag Hammadi library are often considered separately but the current edition of Schneemelcher also contains eleven Nag Hammadi texts. Books that are known objectively not to have existed in antiquity are usually not considered part of the New Testament Apocrypha. Among these are the Libellus de Nativitate Sanctae Mariae (also called the "Nativity of Mary") and the Latin Infancy gospel. The latter two did not exist in antiquity, and they seem to be based on the earlier Infancy gospels. Four gospels came to be accepted as part of the New Testament canon.

Many Evangelical Christian groups (which have their origin in c. 1730 England) do not accept the theory that the Christian Bible was not known until various local and Ecumenical Councils, which they deem to be "Roman-dominated", made their official declarations. These groups believe that the New Testament supports that Paul (2 Timothy 4:11–13), Peter (2 Peter 3:15–16), and ultimately John (Revelation 22:18–19) finalized the canon of the New Testament. Some note that Peter, John, and Paul wrote 20 (or 21) of the 27-books of the NT and personally knew all the other NT
