13 They affirm that many of his disciples were not aware of the descent of Christ into him; but that, when Christ did descend on Jesus, he then began to work miracles, and heal, and announce the unknown Father, and openly to confess himself the son of the first man. The powers and the father of Jesus were angry at these proceedings, and laboured to destroy him; and when he was being led away for this purpose, they say that Christ himself, along with Sophia, departed from him into the state of an incorruptible Æon, while Jesus was crucified. Christ, however, was not forgetful of his Jesus, but sent down a certain energy into him from above, which raised him up again in the body, which they call both animal and spiritual; for he sent the mundane parts back again into the world. When his disciples saw that he had risen, they did not recognise him— no, not even Jesus himself, by whom he rose again from the dead. And they assert that this very great error prevailed among his disciples, that they imagined he had risen in a mundane body, not knowing that “flesh and blood do not attain to the kingdom of God.”
