Do you see how he has cleared it of all blame? For “sin,” he says, “taking occasion by the commandment,” it was, and not the Law, that increased the concupiscence, and the reverse of the Law's intent was brought about. This came of weakness, and not of any badness. For when we desire a thing, and then are hindered of it, the flame of the desire is but increased. Now this came not of the Law; for it hindered us (3 manuscripts endeavored) of itself to keep us off from it; but sin, that is, your own listlessness and bad disposition, used what was good for the reverse. But this is no fault in the physician, but in the patient who applies the medicine wrongly. For the reason of the Law being given was, not to inflame concupiscence, but to extinguish it, though the reverse came of it. Yet the blame attaches not to it, but to us. Since if a person had a fever, and wanted to take cold drink when it was not good for him, and one were not to let him take his fill of it, and so increase his lust after this ruinous pleasure, one could not deservedly be found fault with. For the physician's business is simply prohibiting it, but the restraining himself is the patient's. And what if sin did take occasion from it? Surely there are many bad men who by good precepts grow in their own wickedness. For this was the way in which the devil ruined Judas, by plunging him into avarice, and making him steal what belonged to the poor. However it was not the being entrusted with the bag that brought this to pass, but the wickedness of his own spirit. And Eve, by bringing Adam to eat from the tree, threw him out of Paradise. But neither in that case was the tree the cause, even if it was through it that the occasion took place. But if he treats the discussion about the Law with somewhat of vehemence, do not feel surprise. For Paul is making a stand against the present exigency, and suffers not his language to give a handle even to those that suspected otherwise, but takes great pains to make the present statement correct. Do not then sift what he is now going on to say (4 manuscripts “here saying”) by itself, but put beside it the purpose by which he is led on to speak of these things, and reckon for the madness of the Jews, and their vigorous spirit of contention, which as he desires earnestly to do away with, he seems to bear violently (πολὺς πνεἵν) against the Law, not to find fault with it, but to unnerve their vigor. For if it is any reproach to the Law that sin takes occasion by it, this will be found to be the case in the New Testament also. For in the New Testament there are thousands of laws, and about many more (“far more,” Field) important matters. And one may see the same come to pass there also, not with regard to covetousness only, but to all wickedness generally. For He says, “if I had not come and spoken unto them, they had not had sin,” Here then sin finds a footing in this fact, and so the greater punishment. And again when Paul discourses about grace, he says, “Of how much sorer punishment, suppose ye, shall he be counted worthy, who has trodden under foot the Son of God.” Has not then the worse punishment its origin from hence, from the greater benefit? And the reason why he says the Greeks were without excuse was, because being honored with the gift of reason, and having gotten a knowledge of the beauty of the creation, and having been placed in a fair way for being led by it to the Creator, they did not so use the wisdom of God, as it was their duty. Do you see that to the wicked in all cases occasions of greater punishment result from good things? But we shall not in this accuse the benefits of God, but rather upon this even admire them the more: but we shall throw the blame on the spirit of those who abuse the blessings to contrary purpose. Let this then be our line with regard to the Law also. But this is easy and feasible— the other is what is a difficulty. How is it that he says “I had not known lust except the Law had said, You shall not covet?” Now if man had not known lust, before he received the Law, what was the reason for the flood, or the burning of Sodom? What does he mean then? He means vehement lust: and this is why he did not say, lust, but “all manner of concupiscence,” intimating, in that, its vehemency. And what, it will be said, is the good of the Law, if it adds to the disorder? None; but much mischief even. Yet the charge is not against the Law, but the listlessness of those who received it. For sin wrought it, though by the Law. But this was not the purpose of the Law, nay, the very opposite, Sin then became stronger, he says, and violent. But this again is no charge against the Law but against their obstinacy. “For without the Law sin is dead.” That is, was not so ascertainable. For even those before the Law knew that they had sinned, but they came to a more exact knowledge of it after the giving of the Law. And for this reason they were liable to a greater accusation: since it was not the same thing to have nature to accuse them, and besides nature the Law, which told them distinctly every charge.
Ver. 9. “For I was alive without the Law once.”
When, pray, was that? Before Moses. See how he sets himself to show that it, both by the things it did, and the things it did not do, weighed down human nature. For when “I was alive without the Law,” he means, I was not so much condemned.
“But when the commandment came, sin revived, and I died.”
This seems indeed to be an accusing of theLaw. But if any one will look closely at it, it will be seen to be even an encomium of it. For it did not give existence to sin that before was not, but only pointed out what had escaped notice. And this is even a praise of the Law, if at least before it they had been sinning without perceiving it. But when this came, if they gained nothing besides from it, at all events this they were distinctly made acquainted with, the fact that they had been sinning. And this is no small point, with a view to getting free from wickedness. Now if they did not get free, this has nothing to do with the Law; which framed everything with a view to this end, but the accusation lies wholly against their spirit, which was perverse beyond all supposition. For what took place was not the natural thing—their being injured by things profitable. And this is why he says “And the commandment, which was ordained to life, I found to be unto death.” He does not say, “it was made,” or “it brought forth” death, but “was found,” so explaining the novel and unusual kind of discrepancy, and making the whole fall upon their own pate. For if, he says, you would know the aim of it, it led to life, and was given with this view. But if death was the issue of this, the fault is with them that received the commandment, and not of this, which was leading them to life. And this is a point on which he has thrown fresh light by what follows.
Ver. 11. “For sin taking occasion by the commandment deceived me, and by it slew me.”
You observe how he everywhere keeps to sin, and entirely clears the Law of accusation. And so he proceeds as follows.
Ver. 12. “Wherefore the law is holy, and the commandment holy, and just, and good.”
