Acts or Disputation Against Fortunatus the Manichaean

The next day, a notary having again been summoned, the discussion was conducted as follows:

Fortunatus said: I say that God Almighty brings forth from Himself nothing evil, and that the things that are His remain incorrupt, having sprung and being born from an inviolable source; but other contrary things which have their being in this world, do not flow from God nor have appeared in this world with God as their author; that is to say, they do not derive their origin from God. These things therefore we have received in the belief that evil things are foreign to God.

20. Augustine said: And our faith is this, that God is not the progenitor of evil things, neither has He made any evil nature. But since both of us agree that God is incorruptible and incontaminable, it is the part of the prudent and faithful to consider, which faith is purer and worthier of the majesty of God; that in which it is asserted that either the power of God, or some part of God, or the Word of God, can be changed, violated, corrupted, fettered; or that in which it is said that Almighty God and His entire nature and substance can never be corrupted in any part, but that evils have their being by the voluntary sin of the soul, to which God gave free will. Which free will if God had not given, there could be no just penal judgment, nor merit of righteous conduct, nor divine instruction to repent of sins, nor the forgiveness of sins itself which God has bestowed upon us through our Lord Jesus Christ. Because he who sins not voluntarily, sins not at all. This I suppose to be open and perspicuous to all. Wherefore it ought not to trouble us if according to our deserts we suffer some inconveniences in the things God has made. For as He is good, that He should constitute all things; so He is just, that He may not spare sins, which sins, as I have said, unless free will were in us, would not be sins. For if any one, so to speak, should be bound by some one in his other members, and with his hand something false should be written without his own will, I ask whether if this were laid open before a judge, he could condemn this one for the crime of falsehood. Wherefore, if it is manifest that there is no sin where there is not free exercise of will, I wish to hear what evil the soul which you call either part, or power, or word, or something else, of God, has done, that it should be punished by God, or repent of sin, or merit forgiveness, since it has in no way sinned?

Fortunatus said: I proposed concerning substances, that God is to be regarded as creator only of good things, but as the avenger of evil things, for the reason that evil things are not of Him. Therefore for good reason I think this, and that God avenges evil things because they are not of Himself. But if they were from Him, either He would give them license to sin, as you say that God has given free will, He would be already found a participator in my fault, because He would be the author of my fault; or ignorant what I should be, he left me whom he did not constitute worthy of Himself. This therefore is proposed by me, and what I ask now is, whether God instituted evil or not? And whether He Himself instituted the end of evils. For it appears from these things, and the evangelical faith teaches, that the things which we have said were made by God Himself as God the Creator, as having been created and begotten by Him, are to be esteemed incorruptible. These things I also proposed which belong to our belief, and which can be confirmed by you in that profession of ours, without prejudice to the authority of the Christian faith. And because I can in no way show that I rightly believe, unless I should confirm that belief by the authority of the Scriptures, this is therefore what I have insinuated, what I have said. Either if evil things have appeared in the world with God as their author, deign to say so yourself; or if it is right to believe that evil things are not of God, this also the contemplation of those present ought to honor and receive. I have spoken about substances, not about sin that dwells in us. For if what we think to make faults had no origin, we should not be compelled to come to sin or to fault. For because we sinned unwillingly, and are compelled by a substance contrary and hostile to ourselves, therefore we follow the knowledge of things. By which knowledge the soul admonished and restored to pristine memory, recognizes the source from which it derives its existence, in what evil it dwells, by what good works emending again that in which unwillingly it sinned, it may be able through the emendation of its faults, for the sake of good works, to secure for itself the merit of reconciliation with God, our Saviour being the author of it, who teaches us also to practice good things and to flee from evil. For you ask us to believe that not by some contrary nature, but by his own choice, man either serves righteousness or becomes involved in sins; since, no contrary race existing, if the soul, to which as you say God has given free will, having been constituted in the body, dwells alone, it would be without sin, nor would it become involved in sins.
