Romans 3:20

Let us see what terrors the law announces. If it is the things which hold an intermediate place between virtue and vice, such as poverty, disease, obscurity, and humble birth, and the like, these things civil laws hold forth, and are praised for so doing. And those of the Peripatetic school, who introduce three kinds of good things, and think that their opposites are evil, this opinion suits. But the law given to us enjoins us to shun what are in reality bad things, adultery, uncleanness, pæderasty, ignorance, wickedness, soul-disease, death (not that which severs the soul from the body, but that which severs the soul from truth). For these are vices in reality, and the workings that proceed from them are dreadful and terrible. …

The most of men have a disposition unstable and heedless, like the nature of storms. “Want of faith has done many good things, and faith evil things.” And Epicharmus says, “Don’t forget to exercise incredulity; for it is the sinews of the soul.” Now, to disbelieve truth brings death, as to believe, life; and again, to believe the lie and to disbelieve the truth hurries to destruction. The same is the case with self-restraint and licentiousness. To restrain one’s self from doing good is the work of vice; but to keep from wrong is the beginning of salvation. So the Sabbath, by abstinence from evils, seems to indicate self-restraint. …

40. I wish you to know, most pious father, that in these days there has arrived in our parts a certain person named Manes, who gives out that he is to complete the doctrine of the New Testament. And in the statements which he has made there have been some things, indeed, which may harmonize with our faith; but there have been also certain affirmations of his which seem very far removed from what has come down to us by the tradition of our fathers. For he has interpreted some doctrines in a strange fashion, imposing on them certain notions of his own, which have appeared to me to be altogether foreign and opposed to the faith. On the ground of these facts I have now been induced to write this letter to you, knowing the completeness and fulness of your intelligence in doctrine, and being assured that none of these things can escape your cognizance. …

First, we must see what it is to live after the flesh, and what to live after the spirit. For any one who either does not recollect, or does not sufficiently weigh, the language of sacred Scripture, may, on first hearing what we have said, suppose that the Epicurean philosophers live after the flesh, because they place man’s highest good in bodily pleasure; and that those others do so who have been of opinion that in some form or other bodily good is man’s supreme good; and that the mass of men do so who, without dogmatizing or philosophizing on the subject, are so prone to lust that they cannot delight in any pleasure save such as they receive from bodily sensations: and he may suppose that the Stoics, who place the supreme good of men in the soul, live after the spirit; for what is man’s soul, if not spirit? But in the sense of the divine Scripture both are proved to live after the fle …

In enunciating this proposition of ours, then, that because some live according to the flesh and others according to the spirit, there have arisen two diverse and conflicting cities, we might equally well have said, “because some live according to man, others according to God.” For Paul says very plainly to the Corinthians, “For whereas there is among you envying and strife, are ye not carnal, and walk according to man?” So that to walk according to man and to be carnal are the same; for by flesh , that is, by a part of man, man is meant. For before he said that those same persons were animal whom afterwards he calls carnal, saying, “For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. …

The proofs, then, of this last judgment of God which I propose to adduce shall be drawn first from the New Testament, and then from the Old. For although the Old Testament is prior in point of time, the New has the precedence in intrinsic value; for the Old acts the part of herald to the New. We shall therefore first cite passages from the New Testament, and confirm them by quotations from the Old Testament. The Old contains the law and the prophets, the New the gospel and the apostolic epistles. Now the apostle says “By the law is the knowledge of sin. …

Now of this Mediator it would occupy too much space to say anything at all worthy of Him; and, indeed, to say what is worthy of Him is not in the power of man. For who will explain in consistent words this single statement, that “the Word was made flesh, and dwelt among us,” so that we may believe on the only Son of God the Father Almighty, born of the Holy Ghost and the Virgin Mary. The meaning of the Word being made flesh, is not that the divine nature was changed into flesh, but that the divine nature assumed our flesh. And by “flesh” we are here to understand “man,” the part being put for the whole, as when it is said: “By the deeds of the law shall no flesh be justified,” that is, no man. …

7. This conflict none experience in themselves, save such as war on the side of the virtues, and war down the vices: nor doth any thing storm the evil of lust, save the good of Continence. But there are, who, being utterly ignorant of the law of God, account not evil lusts among their enemies, and through wretched blindness being slaves to them, over and above think themselves also blessed, by satisfying them rather than taming them. But whoso through the Law have come to know them, (“For through the Law is the knowledge of sin,” and, “Lust,” saith he, “I knew not, unless the Law should say, Thou shalt not lust after,” and yet are overcome by their assault, because they live under the Law, whereby what is good is commanded, but not also given: they live not under Grace, which gives through the Holy Spirit what is commanded through the Law: unto these the Law therefore entered, that in th …

11. But some one will say to me that it is one thing to live after man, another thing to live after the flesh; because man forsooth is a rational creature, and there is in him a rational soul, whereby he differs from the beast: but the flesh is the lowest and earthly part of man, and thus to live after it is faulty: and for this reason, he who lives after man, assuredly lives not after the flesh, but rather after that part of man, whereby he is man, that is, after the spirit of the mind whereby he excels the beasts. …

“But,” say they, “we do praise God as the Author of our righteousness, in that He gave the law, by the teaching of which we have learned how we ought to live.” But they give no heed to what they read: “By the law there shall no flesh be justified in the sight of God.” This may indeed be possible before men, but not before Him who looks into our very heart and inmost will, where He sees that, although the man who fears the law keeps a certain precept, he would nevertheless rather do another thing if he were permitted. …

Here, perhaps, it may be said by that presumption of man, which is ignorant of the righteousness of God, and wishes to establish one of its own, that the apostle quite properly said, “For by the law shall no man be justified,” inasmuch as the law merely shows what one ought to do, and what one ought to guard against, in order that what the law thus points out may be accomplished by the will, and so man be justified, not indeed by the power of the law, but by his free determination. But I ask your attention, O man, to what follows. “But now the righteousness of God,” says he, “without the law is manifested, being witnessed by the law and the prophets.” Does this then sound a light thing in deaf ears? He says, “The righteousness of God is manifested.” Now this righteousness they are ignorant of, who wish to establish one of their own; they will not submit themselves to it. …

The law, then, of deeds, that is, the law of works, whereby this boasting is not excluded, and the law of faith, by which it is excluded, differ from each other; and this difference it is worth our while to consider, if so be we are able to observe and discern it. Hastily, indeed, one might say that the law of works lay in Judaism, and the law of faith in Christianity; forasmuch as circumcision and the other works prescribed by the law are just those which the Christian system no longer retains. But there is a fallacy in this distinction, the greatness of which I have for some time been endeavoring to expose; and to such as are acute in appreciating distinctions, especially to yourself and those like you, I have possibly succeeded in my effort. …
