14. And some indeed, who are used to excuse their own sins, complain that they are driven to sin by fate, as though the stars had decreed this, and heaven had first sinned by decreeing such, in order that man should after sin by committing such, and thus had rather impute their sin to fortune: who think that all things are driven to and fro by chance accidents, and yet contend that this their wisdom and assertion is not of chance rashness, but of ascertained reason. What madness then is it, to lay to reason their discussions, and to make their actions subject to accidents! Others refer to the devil the whole of what they do ill: and will not have even a share with him, whereas they may suspect whether he by hidden suggestions hath persuaded them to evil, and on the other hand cannot doubt that they have consented to those suggestions, from whatever source they have come. There are also they who extend their defense of self unto an accusation of God, wretched by the divine judgment, but blasphemers by their own madness. For against Him they bring in from a contrary principle a substance of evil rebelling, which He could not have resisted, had He not blended with that same that was rebelling a portion of His own Substance and Nature, for it to contaminate and corrupt; and they say that they then sin when the nature of evil prevails over the nature of God. This is that most unclean madness of the Manichæans, whose devilish devices the undoubted truth most easily overthrows; which confesses that the nature of God is incapable of contamination and corruption. But what wicked contamination and corruption do they not deserve to have believed of them, by whom God, Who is good in the very highest degree, and in a way that admits not of comparison, is believed to be capable of contamination and corruption? c15. And there are also they who in excuse of their sins so accuse God, as to say that sins are pleasing to Him. For, if they were displeasing, say they, surely by His most Almighty power He would by no means suffer them to take place. As though indeed God suffered sins to be unpunished, even in the case of those whom by remission of sins He frees from eternal punishment! No one forsooth receives pardon of more grievous punishment due, unless he hath suffered some punishment, be it what it may, although far less than what was due: and the fullness of mercy is so conveyed, as that the justice also of discipline is not abandoned. For also sin, which seems unavenged, hath its own attendant punishment, so that there is no one but by reason of what he hath done either suffers pain from bitterness, or suffers not through blindness. As therefore you say, Why doth He permit those things, if they are displeasing? so I say, Why doth He punish them, if they are pleasing? And thus, as I confess that those things would not take place at all, unless they were permitted by the Almighty, so confess thou that what are punished by the Just One ought not to be done; in order that, by not doing what He punishes, we may deserve to learn of Him, why He permits to exist what He punishes. For, as it is written, "solid food is for the perfect," 
wherein they who have made good progress already understand, that it pertained rather unto the Almighty power of God, to allow the existence of evils coming from the free choice of the will. So great forsooth is His Almighty goodness, as that even of evil He can make good, either by pardoning, or by healing, or by fitting and turning unto the profit of the pious, or even by most justly taking vengeance. For all these are good, and most worthy a good and Almighty God: and yet they are not made save of evils. What therefore better, what more Almighty, than He, Who, whereas He maketh no evil, even of evils maketh well? They who have done ill cry unto Him, "Forgive us our debts;" 
He hears, He pardons. Their own evils have hurt the sinners; He helps and heals their sicknesses. The enemies of His people rage; of their rage He makes martyrs. Lastly, also, He condemns those, whom He judges worthy of condemnation; although they suffer their own evils, yet He doeth what is good. For what is just cannot but be good, and assuredly as sin is unjust, so the punishment of sin is just.
