Romans 8:4

His sic ostensis, age Scripturas, quæ adversantur sophistis hæreticis, jam adducamus, et regulam continentiæ secundum logon seu rationem observandam declaremus. Qui vero intelligit, quæ Scriptura cuique hæresi contraria sit, cam tempestive adhibendo refutabit eos, qui dogmata mandatis contraria fingunt. Atque ut ab alto rem repetamus, lex quidem, sicut prius diximus, illud, “Non concupisces uxorem proximi tui,” prius exclamavit ante conjunctam Domini in Novo Testamento vocem, quæ dicit ex sua ipsius persona: “Audivistis legem præcipientem: Non mœchaberis. Ego autem dico: Non concupisces.” Quod enim vellet lex viros uti moderate uxoribus, et propter solam liberorum susceptionem, ex eo clarum est, quod prohibet quidem eum, qui non habet uxorem, statim cum” captiva” habere consuetudinem. Quod si semel desideraverit, ei, cum tonsa fuerit capillos, permittere ut lugeat triginta diebus. …

Challenge me to front the apostolic line of battle; look at his Epistles: they all keep guard in defence of modesty, of chastity, of sanctity; they all aim their missiles against the interests of luxury, and lasciviousness, and lust. What, in short, does he write to the Thessalonians withal? “For our consolation (originated) not of seduction, nor of impurity:” and, “This is the will of God, your sanctification, that ye abstain from fornication; that each one know how to possess his vessel in sanctification and honour, not in the lust of concupiscence, as (do) the nations which are ignorant of God.” What do the Galatians read? “Manifest are the works of the flesh.” What are these? Among the first he has set “fornication, impurity, lasciviousness:” “(concerning) which I foretell you, as I have foretold, that whoever do such acts are not to attain by inheritance the kingdom of God.” The Rom …

III. For the apostle here sets forth clearly, as I think, three laws: One in accordance with the good which is implanted in us, which clearly he calls the law of the mind. One the law which arises from the assault of evil, and which often draws on the soul to lustful fancies, which, he says,” wars against the law of the mind.” And the third, which is in accordance with sin, settled in the flesh from lust, which he calls the “law of sin which dwells in our members;” which the Evil One, urging on, often stirs up against us, driving us to unrighteousness and evil deeds. For there seems to be in ourselves one thing which is better and another which is worse. …

7. Augustin replied: If you allow, in consideration of the authority of the Gospel, that Christ said that He came not to destroy the law and the prophets, but to fulfill them, you should show the same consideration to the authority of the apostle, when he says, "All these things were our examples;" and again of Christ, "He was not yea and nay, but in Him was yea; for all the promises of God are in Him yea;" that is, they are set forth and fulfilled in Him. In this way you will see in the clearest light both what law Christ fulfilled, and how He fulfilled it. It is a vain attempt that you make to escape by your three kinds of law and your three kinds of prophets. It is quite plain, and the New Testament leaves no doubt on the matter, what law and what prophets Christ came not to destroy, but to fulfill. The law given by Moses is that which by Jesus Christ became grace and truth. …

After saying, “Not according to the covenant which I made with their fathers in the day that I took them by the hand, to bring them out of the land of Egypt,” observe what He adds: “Because they continued not in my covenant.” He reckons it as their own fault that they did not continue in God’s covenant, lest the law, which they received at that time, should seem to be deserving of blame. For it was the very law that Christ “came not to destroy, but to fulfil.” Nevertheless, it is not by that law that the ungodly are made righteous, but by grace; and this change is effected by the life-giving Spirit, without whom the letter kills. “For if there had been a law given which could have given life, verily righteousness should have been by the law. …

They declare “that we say that the law of the Old Testament was given not for the end that it might justify the obedient, but rather that it might become the cause of greater sin.” Certainly, they do not understand what we say concerning the law; because we say what the apostle says, whom they do not understand. For who can say that they are not justified who are obedient to the law, when, unless they were justified, they could not be obedient? But we say, that by the law is effected that what God wills to be done is heard, but that by grace is effected that the law is obeyed. “For not the hearers of the law,” says the apostle, “are just before God, but the doers of the law shall be justified.” Therefore the law makes hearers of righteousness, grace makes doers. …

4. Who then freeth from death and from bondage, save He, who is “Free among the dead”? Who is “Free among the dead,” save He who among sinners is without sin? “Lo, the prince of the world cometh,” saith our Redeemer Himself, our Deliverer, “Lo, the prince of the world cometh, and shall find nothing in Me.” He holds fast those whom he hath deceived, whom he hath seduced, whom he hath persuaded to sin and death; “in Me shall he find nothing.” Come, Lord, Redeemer come, come; let the captive acknowledge thee, him that leadeth captive flee thee; be Thou my Deliverer. Lost as I was, He hath found me in Whom the devil findeth nothing that cometh of the flesh. The prince of this world findeth in Him Flesh, he findeth it but what kind of Flesh? A mortal Flesh, which he can seize, which he can crucify, which he can kill. …

This then was one sense in which He fulfilled it. Another, that He did the same through us also; for this is the marvel, that He not only Himself fulfilled it, but He granted this to us likewise. Which thing Paul also declaring said, “Christ is the end of the law for righteousness to every one that believeth.” And he said also, that “He judged sin in the flesh, that the righteousness of the law might be fulfilled in us who walk not after the flesh.” And again, “Do we then make void the law through faith? God forbid! yea, we establish the law.” For since the law was laboring at this, to make man righteous, but had not power, He came and brought in the way of righteousness by faith, and so established that which the law desired: and what the law could not by letters, this He accomplished by faith. On this account He saith, “I am not come to destroy the law.”

Ver. 4 . “That the righteousness of the Law might be fulfilled in us, who walk not after the flesh.” What meaneth this word, righteousness? Why, the end, the scope, the well-doing. For what was its design, and what did it enjoin? To be without sin. This then is made good to us ( κατώρθωται ἡμἵν ) now through Christ. And the making a stand against it, and the getting the better of it, came from Him. But it is for us to enjoy the victory. Then shall we never sin henceforth? We never shall unless we have become exceedingly relaxed and supine. …

55. To give a witness then, and for our sakes to undergo death, to raise man up and destroy the works of the devil, the Saviour came, and this is the reason of His incarnate presence. For otherwise a resurrection had not been, unless there had been death; and how had death been, unless He had had a mortal body? This the Apostle, learning from Him, thus sets forth, ‘Forasmuch then as the children are partakers of flesh and blood, He also Himself likewise took part of the same; that through death He might bring to nought him that had the power of death, that is, the devil, and deliver them who through fear of death were all their lifetime subject to bondage.’ And, ‘Since by man came death, by man came also the resurrection of the dead.’ And again, ‘For what the Law could not do, in that it was weak through the flesh, God, sending His own Son in the likeness of sinful flesh, and for sin, co …

Therefore the law of my mind, that is, the conscience, sympathises with the law of God, that is, the precept, and makes that its will. But the law of sin, that is to say, the assault made through the law that is in our members, or through the lust and inclination and movement of the body and of the irrational part of the soul, is in opposition to the law of my mind, that is to conscience, and takes me captive (even though I make the law of God my will and set my love on it, and make not sin my will), by reason of commixture: and through the softness of pleasure and the lust of the body and of the irrational part of the soul, as I said, it leads me astray and induces me to become the servant of sin. …

12. Interpreting which truth, the Apostle says: “For God, sending His own Son in the likeness of sinful flesh, and for sin condemned sin in the flesh, that the righteousness of the Law might be fulfilled in us.” He does not say “in the likeness of flesh,” for Christ took on Himself the reality not the likeness of flesh; nor does He say in the likeness of sin, for He did no sin, but was made sin for us. Yet He came “in the likeness of sinful flesh;” that is, He took on Him the likeness of sinful flesh, the likeness, because it is written: “He is man, and who shall know Him?” He was man in the flesh, according to His human nature, that He might be recognized, but in power was above man, that He might not be recognized, so He has our flesh, but has not the failings of this flesh.
