6 The same conclusion will follow, although they affirm that the production of Æons sprang from Logos, as branches from a tree, since Logos has his generation from their Father. For all [the Æons] are formed of the same substance with the Father, differing from one another only in size, and not in nature, and filling up the greatness of the Father, even as the fingers complete the hand. If therefore He exists in passion and ignorance, so must also those Æons who have been generated by Him. But if it is impious to ascribe ignorance and passion to the Father of all, how can they describe an Æon produced by Him as being passible; and while they ascribe the same impiety to the very wisdom (Sophia) of God, how can they still call themselves religious men?
