Against the Fundamental Epistle of Manichaeus

My prayer to the one true, almighty God, of whom, and through whom, and in whom are all things, has been, and is now, that in opposing and refuting the heresy of you Manichæans, as you may after all be heretics more from thoughtlessness than from malice, He would give me a mind calm and composed, and aiming at your recovery rather than at your discomfiture.
