The Gospel of Judas was condemned by Irenaeus in his anti-Gnostic work "Adversus Haereses" (Against Heresies), written in about 180. Despite this, The Gospel of Judas differs from other non-Nicene Gospels in several ways. Far from arguing that the physical body is a prison which needs to be escaped from, the Gospel of Judas portrays Jesus as able to leave his body at will and take on other forms, appearing to be a child. In the text, Jesus is shown leaving his body, journeying to the imperishable realm and returning to his body. Unlike other non-Nicene Gospels, the Gospel of Judas is Sethian in orientation in that Adam's son Seth is seen as a spiritual ancestor. As in other Sethian documents, Jesus is equated with Seth: "The first is Seth, who is called Christ".
