6 On this account, Ialdabaoth, becoming uplifted in spirit, boasted himself over all those things that were below him, and exclaimed, “I am father, and God, and above me there is no one.” But his mother, hearing him speak thus, cried out against him, “Do not lie, Ialdabaoth: for the father of all, the first Anthropos (man), is above you; and so is Anthropos the son of Anthropos.” Then, as all were disturbed by this new voice, and by the unexpected proclamation, and as they were inquiring whence the noise proceeded, in order to lead them away and attract them to himself, they affirm that Ialdabaoth exclaimed, “Come, let us make man after our image.” The six powers, on hearing this, and their mother furnishing them with the idea of a man (in order that by means of him she might empty them of their original power), jointly formed a man of immense size, both in regard to breadth and length.
But as he could merely writhe along the ground, they carried him to their father; Sophia so labouring in this matter, that she might empty him (Ialdabaoth) of the light with which he had been sprinkled, so that he might no longer, though still powerful, be able to lift up himself against the powers above. They declare, then, that by breathing into man the spirit of life, he was secretly emptied of his power; that hence man became a possessor of nous (intelligence) and enthymesis (thought); and they affirm that these are the faculties which partake in salvation. He [they further assert] at once gave thanks to the first Anthropos (man), forsaking those who had created him.
