He does not say did abound, but “did much more abound.” For it was not remission from punishment only that He gave us, but that from sins, and life also. As if any were not merely to free a man with a fever from his disease, but to give him also beauty, and strength, and rank; or again, were not to give one an hungered nourishment only, but were to put him in possession of great riches, and were to set him in the highest authority. And how did sin abound? Some will say. The Law gave countless commands. Now since they transgressed them all, trangression became more abundant. Do you see what a great difference there is between grace and the Law? For the one became an addition to the condemnation, but the other, a further abundance of gifts. Having then mentioned the unspeakable munificence, he again discusses the beginning and the root both of death and of life. What then is the root of death? It is sin. Wherefore also he says,
Ver. 21. “That as sin reigned unto death, even so might grace reign through righteousness unto eternal life, through our Lord Jesus Christ.”
This he says to show that the latter ranks as a king, the former, death, as a soldier, being marshalled under the latter, and armed by it. If then the latter (i.e. sin) armed death, it is plain enough that the righteousness destructive hereof, which by grace was introduced, not only disarms death, but even destroys it, and undoes entirely the dominion thereof, in that it is the greatest of the two, as being brought in not by man and the devil, but by God and grace, and leading our life unto a goodlier estate, and to blessings unlimited. For of it there will never be any end (to give you a view of its superiority from this also). For the other cast us out of our present life, but grace, when it came, gave us not the present life, but the immortal and eternal one. But for all these things Christ is our voucher. Doubt not then for your life if you have righteousness, for righteousness is greater than life as being mother of it.
Chap. vi. ver. 1. “What then? Shall we continue in sin, that grace may abound? God forbid.”
He is again turning off to exhortation, yet introducing it not directly, lest he should seem to many to be irksome and vexing, but as if it rose out of the doctrines. For if, even so diversifying his address, he was afraid of their being offended at what he said, and therefore said, “I have written the more boldly unto you in some sort,” much more would he have seemed to them, had he not done so, to be too harsh. Since then he showed the greatness of the grace by the greatness of the sins it healed, and owing to this it seemed in the eyes of the unthinking to be an encouragement to sin (for if the reason, they would say, why greater grace was shown, was because we had done great sins, let us not give over sinning, that grace may be more displayed still), now that they might not say this or suspect it, see how he turns the objection back again. First he does it by his deprecation. “God forbid.” And this he is in the habit of doing at things confessed on all hands to be absurd. And then he lays down an irrefragable argument. And what is it?
Ver. 2. “How shall we,” he says, “that are dead to sin, live any longer therein?”
What does “we are dead” mean? Does it mean that as for that, and as far as it goes, we have all received the sentence of death? Or, that we became dead to it by believing any being enlightened. This is what one should rather say, since the sequel makes this clearly right. But what is becoming dead to it? The not obeying it in anything any more. For this baptism effected once for all, it made us dead to it. But this must of our own earnestness thenceforth continually be maintained, so that, although sin issue countless commands to us, we may never again obey it, but abide unmovable as a dead man does. And indeed he elsewhere says that sin itself is dead. But there he sets that down as wishing to show that virtue is easy, But here, as he earnestly desires to rouse the hearer, he puts the death on his side. Next, since what was said was obscure, he again explains, using what he had said also in the way of reproof.
<!--<span class="stiki"></span>-->Ver. 3, 4. “Do you not know,” he says, “my brethren, that so many of us as were baptized into Christ were baptized into His death? Therefore we are buried with Him by baptism into death.”
What does being “baptized into His Death” mean? That it is with a view to our dying as He did. For Baptism is the Cross. What the Cross then, and Burial, is to Christ, that Baptism has been to us, even if not in the same respects. For He died Himself and was buried in the Flesh, but we have done both to sin. Wherefore he does not say, planted together in His Death, but in the likeness of His Death. For both the one and the other is a death, but not of the same subject; since the one is of the Flesh, that of Christ; the other of sin, which is our own. As then that is real, so is this. But if it be real, then what is of our part again must be contributed. And so he proceeds,
“That as Christ was raised up from the dead by the Glory of the Father, even so we also should walk in newness of life.”
Here he hints, along with the duty of a careful walk, at the subject of the resurrection. In what way? Do you believe, he means, that Christ died, and that He was raised again? Believe then the same of yourself. For this is like to the other, since both Cross and Burial is yours. For if you have shared in Death and Burial, much more will you in Resurrection and Life. For now the greater is done away with, the sin I mean, it is not right to doubt any longer about the lesser, the doing away of death.
