1. The following are the transactions which they narrate as having occurred outside of the Pleroma: The enthymesis of that Sophia who dwells above, which they also term Achamoth, being removed from the Pleroma, together with her passion, they relate to have, as a matter of course, become violently excited in those places of darkness and vacuity [to which she had been banished]. For she was excluded from light and the Pleroma, and was without form or figure, like an untimely birth, because she had received nothing [from a male parent]. But the Christ dwelling on high took pity upon her; and having extended himself through and beyond Stauros, he imparted a figure to her, but merely as respected substance, and not so as to convey intelligence. Having effected this, he withdrew his influence, and returned, leaving Achamoth to herself, in order that she, becoming sensible of her suffering as being severed from the Pleroma, might be influenced by the desire of better things, while she possessed in the meantime a kind of odour of immortality left in her by Christ and the Holy Spirit.

By the celestial crucifixion of Christ, the world was created by the mere matter without form.
