2 Then, again, as to their assertion that the passion of the twelfth Æon was proved through the conduct of Judas, how is it possible that Judas can be compared [with this Æon] as being an emblem of her— he who was expelled from the number of the twelve, and never restored to his place? For that Æon, whose type they declare Judas to be, after being separated from her Enthymesis, was restored or recalled [to her former position]; but Judas was deprived [of his office], and cast out, while Matthias was ordained in his place, according to what is written, “And his bishopric let another take.” They ought therefore to maintain that the twelfth Æon was cast out of the Pleroma, and that another was produced, or sent forth to fill her place; if, that is to say, she is pointed at in Judas. Moreover, they tell us that it was the Æon herself who suffered, but Judas was the betrayer, [and not the sufferer.] Even they themselves acknowledge that it was the suffering Christ, and not Judas, who came to [the endurance of] passion. How, then, could Judas, the betrayer of Him who had to suffer for our salvation, be the type and image of that Æon who suffered?
