Many of the early gospels and books about Jesus and the apostles were written by Gnostics and conflicted with the teachings of what has become known as the proto-Catholic-orthodox branch of Christianity. When Catholic-orthodox Christianity succeeded in eliminating Gnosticism, the gnostic books were destroyed. Other early books were of doubtful provenance and were eliminated from consideration on that ground. Books that were omitted were not in common use by the majority of Christians down through Christian history, had not been accepted as being authored by an apostle or close associate, or contained material considered heretical or at variance with the apostolic witness (such as numerology or referring to a phoenix as an existing creature).
