Psalms 40:5

4. Those impostors, then, whom they designate Mathematicians, I consulted without hesitation, because they used no sacrifices, and invoked the aid of no spirit for their divinations, which art Christian and true piety fitly rejects and condemns. For good it is to confess unto Thee, and to say, “Be merciful unto me, heal my soul, for I have sinned against Thee;” and not to abuse Thy goodness for a license to sin, but to remember the words of the Lord, “Behold, thou art made whole; sin no more, lest a worse thing come unto thee.” All of which salutary advice they endeavour to destroy when they say, “The cause of thy sin is inevitably determined in heaven;” and, “This did Venus, or Saturn, or Mars;” in order that man, forsooth, flesh and blood, and proud corruption, may be blameless, while the Creator and Ordainer of heaven and stars is to bear the blame. …

19. But our very Life descended hither, and bore our death, and slew it, out of the abundance of His own life; and thundering He called loudly to us to return hence to Him into that secret place whence He came forth to us, first into the Virgin’s womb, where the human creature was married to Him, our mortal flesh, that it might not be for ever mortal, and thence “as a bridegroom coming out of his chamber, rejoicing as a strong man to run a race.” For He tarried not, but ran crying out by words, deeds, death, life, descent, ascension, crying aloud to us to return to Him. And He departed from our sight, that we might return to our heart, and there find Him. For He departed, and behold, He is here. …

18. Thou restoredst me then from that illness, and made sound the son of Thy hand-maid meanwhile in body, that he might live for Thee, to endow him with a higher and more enduring health. And even then at Rome I joined those deluding and deluded “saints;” not their “hearers” only, of the number of whom was he in whose house I had fallen ill, and had recovered, but those also whom they designate “The Elect.” For it still seemed to me “that it was not we that sin, but that I know not what other nature sinned in us.” And it gratified my pride to be free from blame and, after I had committed any fault, not to acknowledge that I had done any, “that Thou mightest heal my soul because it had sinned against Thee;” but I loved to excuse it, and to accuse something else (I wot not what) which was with me, but was not I. …

18. All we therefore, who believe in the Living and True God, Whose Nature, being in the highest sense good and incapable of change, neither doth any evil, nor suffers any evil, from Whom is every good, even that which admits of decrease, and Who admits not at all of decrease in His own Good, Which is Himself, when we hear the Apostle saying, “Walk in the Spirit, and perform ye not the lusts of the flesh. For the flesh lusteth against the Spirit, and the Spirit against the flesh: For these are opposed one to another, that ye do not what ye would.” Far be it from us to believe, what the madness of the Manichees believes, that there are here shown two natures or principles contrary one to another at strife, the one nature of good, the other of evil. …

9. As Cain’s sacrifice of the fruit of the ground is rejected, while Abel’s sacrifice of his sheep and the fat thereof is accepted, so the faith of the New Testament praising God in the harmless service of grace is preferred to the earthly observances of the Old Testament. For though the Jews were right in practising these things, they were guilty of unbelief in not distinguishing the time of the New Testament when Christ came, from the time of the Old Testament. …

Nor ought it to disturb us that the apostle described them as doing that which is contained in the law “ by nature, ”, not by the Spirit of God, not by faith, not by grace. For it is the Spirit of grace that does it, in order to restore in us the image of God, in which we were naturally created. Sin, indeed, is contrary to nature, and it is grace that heals it, on which account the prayer is offered to God, “Be merciful unto me: heal my soul; for I have sinned against Thee.” Therefore it is by nature that men do the things which are contained in the law; for they who do not, fail to do so by reason of their sinful defect. …

Do we then by grace make void free will? God forbid! Nay, rather we establish free will. For even as the law by faith, so free will by grace, is not made void, but established. For neither is the law fulfilled except by free will; but by the law is the knowledge of sin, by faith the acquisition of grace against sin, by grace the healing of the soul from the disease of sin, by the health of the soul freedom of will, by free will the love of righteousness, by love of righteousness the accomplishment of the law. Accordingly, as the law is not made void, but is established through faith, since faith procures grace whereby the law is fulfilled; so free will is not made void through grace, but is established, since grace cures the will whereby righteousness is freely loved. …

You may now see (what bears very closely on our subject) how he endeavours to exhibit human nature, as if it were wholly without fault, and how he struggles against the plainest of God’s Scriptures with that “wisdom of word” which renders the cross of Christ of none effect. That cross, however, shall certainly never be made of none effect; rather shall such wisdom be subverted. Now, after we shall have demonstrated this, it may be that God’s mercy may visit him, so that he may be sorry that he ever said these things: “We have,” he says, “first of all to discuss the position which is maintained, that our nature has been weakened and changed by sin. …

“Inasmuch,” says he, “as not to sin is ours, we are able to sin and to avoid sin.” What, then, if another should say: “Inasmuch as not to wish for unhappiness is ours, we are able both to wish for it and not to wish for it?” And yet we are positively unable to wish for it. For who could possibly wish to be unhappy, even though he wishes for something else from which unhappiness will ensue to him against his will? Then again, inasmuch as, in an infinitely greater degree, it is God’s not to sin, shall we therefore venture to say that He is able both to sin and to avoid sin? God forbid that we should ever say that He is able to sin! For He cannot, as foolish persons suppose, therefore fail to be almighty, because He is unable to die, or because He cannot deny Himself. …

2. The five porches in which the infirm folk lay signify the Law, which was first given to the Jews and to the people of Israel by Moses the servant of God. For this Moses the minister of the Law wrote five books. In relation therefore to the number of the books which he wrote, the five porches figured the Law. But because the Law was not given to heal the infirm, but to discover and to manifest them; for so saith the Apostle, “For if there had been a law given which could have given life, verily righteousness should have been by the Law; But the Scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe;” therefore in those porches the sick folk lay, but were not cured. For what saith he? “If there had been a law given which could have given life.” Therefore those porches which figured the Law could not cure the sick. …

11. Seek in the Father and Son a separation, thou findest none; no, not if thou hast mounted high; no, not even if thou hast reached something above thy mind. For if thou turnest about among the things which thy wandering mind makes for itself, thou talkest with thine own imaginations, not with the Word of God; thine own imaginations deceive thee. Mount also beyond the body, and understand the mind; mount also beyond the mind, and understand God. Thou reachest not unto God, unless thou hast passed beyond the mind; how much less thou reachest unto God, if thou hast tarried in the flesh! They who think of the flesh, how far are they from understanding what God is! since they would not be there even if they knew the mind. Man recedes far from God when his thoughts are of the flesh; and there is a great difference between flesh and mind, yet a greater between mind and God. …

5. But why this? Because He “scourgeth every son whom He receiveth.” Why this? Because to men sinning was it said, “In the sweat of thy face shalt thou eat bread.” Therefore because all these chastisements, in which all our bed is turned in our infirmity, man ought to acknowledge that he suffers for sin; let him turn himself, and say what follows: “I said, Lord, be merciful unto me; heal my soul, for I have sinned against Thee” ( ver. 4 ). O Lord, by tribulations do Thou exercise me; to be scourged Thou judgest every son whom Thou wilt receive, who sparedst not even the Only-Begotten. He indeed without sin was scourged; but I say, “I have sinned against Thee.”…
