Protévangile de Jacques
Many non-canonical gospels were also written, all later than the four canonical gospels, and like them advocating the particular theological views of their various authors. Important examples include the Gospel of Thomas, the Gospel of Peter, the Gospel of Judas, the Gospel of Mary, infancy gospels such as the Gospel of James (the first to introduce the perpetual virginity of Mary), and gospel harmonies such as the Diatessaron.
