Disputation of the First Day
15 Augustine said: Those contrary things that move you so that we think adversely, have happened on account of our sin, that is, on account of the sin of man. For God made all things good, and ordered them well; but He did not make sin, and our voluntary sin is the only thing that is called evil. There is another kind of evil, which is the penalty of sin. Since therefore there are two kinds of evil, sin and the penalty of sin, sin does not pertain to God; the penalty of sin pertains to the avenger. For as God is good who constituted all things, so He is just in taking vengeance on sin. Since therefore all things are ordered in the best possible way, which seem to us now to be adverse, it has deservedly happened to fallen man who was unwilling to keep the law of God. For God gave free will to the rational soul which is in man. For thus it would have been possible to have merit, if we should be good voluntarily and not of necessity. Since therefore it behooves us to be good not of necessity but voluntarily, it behooved God to give to the soul free will. But to this soul obeying His laws, He subjected all things without adversity, so that the rest of the things that God made should serve it, if also the soul itself had willed to serve God. But if it should refuse to serve God, those things that served it should be converted into its punishment. Wherefore if all things are rightly ordered by God, and are good, neither does God suffer evil.
Fortunatus said: He does not suffer, but prevents evil.
16. Augustine said: From whom then was He about to suffer it?
Fortunatus said: This is my point, that He wished to prevent it, not rashly, but by power and prescience. But deny evil to be apart from God, when other precepts can be shown which are done apart from His will. A precept is not introduced, unless where there is contrariety. The free faculty of living is not given except where there is a fall according to the argument of the apostle who says: "And you did he quicken, when you were dead in your trespasses and sins, wherein aforetime ye walked according to the rulership of this world, according to the prince of the power of the air, of the spirit that now works in the souls of disobedience; among whom we also all once lived in the lusts of our flesh, doing the desires of the counsels of the flesh, and were by nature children of wrath, even as the rest: but God, who is rich in all mercy, had mercy on us. And when we were dead by sins, quickened us together in Christ, by whose grace you have been saved; and at the same time also raised us up, and made us to sit with Him in the heavenly places with Christ Jesus, that in the ages to come He might show the exceeding riches of his grace in kindness toward us in Christ Jesus. For by grace have you been saved through faith; and that not of yourselves, for it is a gift of God; not of works, lest any one should glory. For we are his workmanship created in Christ Jesus in good works, which God prepared that we should walk in them. Wherefore remember, that aforetime you were Gentiles in the flesh, who are called uncircumcision, by that which is called circumcision in flesh made by hands, because you were at that time without Christ, alienated from the commonwealth of Israel, and strangers of the covenant, having no hope of the promise, and without God in this world. But now in Christ Jesus, you that once were far off are made near in the blood of Christ. For He is our peace, who made both one, and breaking down the middle wall of partition, the enmities in His flesh, making void by His decrees the law of commandments, that in Himself He might unite the two into one new man, making peace, that He might reconcile them both in one body unto God through the cross, slaying the enmities in Himself. And He came and preached peace unto you that were far off, and peace to them that were near. For through Him we both have our access in one Spirit unto the Father."
17. Augustine said: This passage from the apostle, which you have thought fit to recite, if I mistake not, makes very strongly for my faith and against yours. In the first place, because free will itself, on which I have said that the possibility of the soul's sinning depends, is here sufficiently expressed, when sins are mentioned, and it is said that our reconciliation with God takes place through Jesus Christ. For by sinning we were brought into opposition to God; but by holding to the precepts of Christ we are reconciled to God; so that we who were dead in sins may be made alive by keeping His precepts, and may have peace with Him in one Spirit, from whom we were alienated, by failure to keep His precepts; as is set forth in our faith concerning the man who was first created. I ask of you, therefore, according to that passage which has been read, how can we have sins if contrary nature compels us to do what we do? For he who is compelled by nature to do anything, does not sin. But he who sins, sins by free will. Wherefore would repentance be enjoined upon us, if we have done nothing evil, but only the race of darkness? Likewise, I ask, to whom is forgiveness of sins granted, to us or to the race of darkness? If to the race of darkness, their race will also reign with Him, receiving the forgiveness of sin; but if to us it is manifest that we have sinned voluntarily. For it is the height of folly for him to be pardoned who has done no evil. But he has done no evil, who has done nothing of his own will. Therefore the soul that today promises itself forgiveness of sins and reconciliation to God, if it should cease to sin, and repent of past sins: if it should answer according to your faith and should say: In what have I sinned? In what am I guilty? Why have You expelled me from Your domains, that I might do battle with some sort of race? I have been trodden under foot, I have been mixed up, I have been corrupted, I am worn out, my free will has not been preserved. You know the necessity by which I am preserved: Why dost Thou impute to me the wounds that I have received? Why do You compel me to repentance when You are the cause of my wounds; when You know what I have suffered, what the race of darkness has done against me, Thou being the author who could suffer no harm and yet wishing to save the domains which nothing could injure, You thrusted me down into these miseries. If indeed I am a part of You, who have proceeded from Your bowels, if I am from Your kingdom and Your mouth, I ought not to suffer anything in this race of darkness, so that I being uncorrupted that race should be subjected, if I was a part of the Lord. But now since it cannot be controlled except by my corruption, how can I either be said to be a part of You, or Thou remain inviolable, or not be cruel in wishing me to suffer for those domains, that could in no way be injured by that race of darkness? Respond to this if you please, and deign also to explain to me how it was said by the apostle, "We were by nature children of wrath," who, he says, have been reconciled to God. If therefore they were by nature children of wrath, how do you say that the soul is by nature a daughter and portion of God?
