Romans 8:1

But the apostle pursues the subject, and says, “So then with the mind I myself serve the law of God, but with the flesh the law of sin;” which must be thus understood: “With my mind I serve the law of God,” by refusing my consent to the law of sin; “with my flesh, however,” I serve “the law of sin,” by having the desires of sin, from which I am not yet entirely freed, although I yield them no assent. Then let us observe carefully what he has said after all the above: “There is therefore now no condemnation to them which are in Christ Jesus.” Even now , says he, when the law in my members keeps up its warfare against the law of my mind, and retains in captivity somewhat in the body of this death, there is no condemnation to them which are in Christ Jesus. …

Then he adds the reason why he said all these things: “O wretched man that I am! who shall deliver me from the body of this death? The grace of God, through Jesus Christ our Lord!” And thence he concludes: “Therefore I myself with the mind serve the law of God, but with the flesh the law of sin.” To wit, with the flesh, the law of sin, by lusting; but with the mind, the law of God, by not consenting to that lust. “For there is now no condemnation to those who are in Christ Jesus.” For he is not condemned who does not consent to the evil of the lust of the flesh. “For the law of the Spirit of life in Christ Jesus has made thee free from the law of sin and death,” so that, to wit, the lust of the flesh may not appropriate to itself thy consent. And what follows more and more demonstrates the same meaning. But moderation must be used.

Since then both the rewards thereof are greater, and the power given by the Spirit more abundant, in reason it requires our graces to be greater also. For it is no longer “a land that floweth with milk and honey,” nor a comfortableold age, nor many children, nor corn and wine, and flocks and herds: but Heaven, and the good things in the Heavens, and adoption and brotherhood with the Only-Begotten, and to partake of the inheritance and to be glorified and to reign with Him, and those unnumbered rewards. And as to our having received more abundant help, hear thou Paul, when he saith, “There is therefore no condemnation now to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit:for the law of the Spirit of life hath made me free from the law of sin and death.”

Chap. viii. ver. 1 . “There is therefore no condemnation to them which are in Christ Jesus.” Then as the fact that many fall into sin even after baptism presented a difficulty ( ἀντέπιπτεν ), he consequently hastened to meet it, and says not merely “to them that are in Christ Jesus,” but adds, “who walk not after the flesh;” so showing that all afterward comes of our listlessness. For now we have the power of walking not after the flesh, but then it was a difficult task. Then he gives another proof of it by the sequel, in the words,

37. But why do we argue, and why are we eager to frame a clever and victorious reply to our opponent? “Old things have passed away, behold all things have become new.” I will run through the utterances of the Apostles, and as to the instances afforded by Solomon I added short expositions to facilitate their being understood, so now I will go over the passages bearing on Christian purity and continence, and will make of many proofs a connected series. By this method I shall succeed in omitting nothing relating to chastity, and shall avoid being tediously long. Amongst other passages, Paul the Apostle writes to the Romans: “What fruit then had ye at that time in the things whereof ye are now ashamed? for the end of those things is death. …

Because then the original curse of God has made us carnal and condemned us to thorns and thistles, and our father has sold us by that unhappy bargain so that we cannot do the good that we would, while we are torn away from the recollection of God Most High and forced to think on what belongs to human weakness, while burning with the love of purity, we are often even against our will troubled by natural desires, which we would rather know nothing about; we know that in our flesh there dwelleth no good thing viz., the perpetual and lasting peace of this meditation of which we have spoken; but there is brought about in our case that miserable and wretched divorce, that when with the mind we want to serve the law of God, since we never want to remove our gaze from the Divine brightness, yet surrounded as we are by carnal darkness we are forced by a kind of law of sin to tear ourselves away f …
