Nicene and Post-Nicene Fathers, Vol. IV:
Writings in Connection with the Manichæan Controversy.: Chapter 45

Chapter 45.—Certain Unspeakable Turpitudes Believed, Not Without Reason, Concerning the Manichæans Themselves.

But they say, that through their own Elect that same commingled part and nature of God is purged, by eating and drinking forsooth, (because they say that it is held fettered in all foods); that when they are taken up by the Elect for the nourishment of the body in eating and drinking, it is loosed, sealed, and liberated through their sanctity.  Nor do the wretches pay heed to the fact that this is believed about them not without good reason, and they deny it in vain, so long as they do not anathematize the books of Manichæus and cease to be Manichæans.  For if, as they say, a part of God is fettered in all seeds, and is purged by eating on the part of the Elect; who may not properly believe, that they do what they read in the Thesaurus was done among the powers of heaven and the princes of darkness; since indeed they say that their flesh is also from the race of darkness, and since they do not hesitate to believe and to affirm that the vital substance fettered in them is a part of God?  Which assuredly if it is to be loosed, and purged by eating, as their lamentable error compels them to acknowledge; who does not see, who does not shudder at the greatness and the unspeakableness of what follows?
