A "Gospel of Judas" is mentioned by Irenaeus (Adv. Haer., i.31), Epiphanius (Haer., xxxviii.1), Theodoret, etc., as current in the Gnostic sect of the Cainites, to whom Judas was a hero. It must have been in existence in the 2nd century, but no quotation is given from it (see Baring-Gould, Lost and Hostile Gospels,III , chapter v).
