New Testament document, in addition to some other sources, to write their individual gospel accounts. These three gospels are called the Synoptic gospels because they include many of the same stories, often in the same sequence, and sometimes exactly the same wording. Scholars agree that the Gospel of John was written last, by using a different tradition and body of testimony. In addition, most scholars agree that the author of Luke wrote the Acts of the Apostles. Scholars hold that these books constituted two halves of a single work, Luke-Acts. Strictly speaking, each gospel and the book of Acts is arguably anonymous.
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.
