1 Corinthians 7:19

19.Circumcision is nothing While this similitude was suited to the subject in hand, it appears to have been designedly made use of with the view of reproving, in passing, the superstition and haughtiness of the Jews. For, as the Jews gloried in circumcision, it was possible that many might feel dissatisfied with the want of it, as if their condition were the worse on that account. Paul, therefore, places both conditions upon a level, lest, through hatred of the one, the other should be foolishly desired. These things, however, must be understood as referring to the time when circumcision was at length abolished; for, if he had had an eye to the covenant of God, and his commandment, he would, without doubt, have estimated it higher. In another passage, it is true, he makes light of the letter of circumcision, (Romans 2:27,) and declares that it is of no account in the sight of God; but here, as he simply contrasts circumcision with uncircumcision, and makes both alike, it is certain that he speaks of it as a matter of indifference and of no moment. For the abolishing of it has this effect — that the mystery which had been previously conveyed under it, does not now any longer belong to it: nay more, it is now no longer a sign, but a thing of no use. For baptism has come in the place of the symbol used under the law on this footing, that it is enough that we be circumcised by the Spirit of Christ, while our old man is buried with Christ.

But the keeping of the commandments As this was one of the commandments, so long as the Church was bound to legal ceremonies, we see that it is taken for granted, that circumcision had been abolished by the advent of Christ, so that the use of it, indeed, was allowed among the ignorant and weak, but advantage in it — there was none. For Paul speaks of it here as a thing of no moment: “As these are outward things, let them not take up your attention, but devote yourself rather to piety and the duties which God requires, and which are alone precious in his sight.” As to the circumstance that Papists bring forward this passage for the purpose of overthrowing justification by faith, it is utterly childish; for Paul is not disputing here as to the ground of justification, or the way in which we obtain it, but simply as to the object to which the aim of believers ought to be directed. “Do not occupy yourselves to no purpose in things of no profit, but, on the contrary, exercise yourselves in duties that are well pleasing to God.”
