If then the uncircumcision, etc. This is a very strong argument. Every thing is below its end and subordinate to it. Circumcision looks to the law, and must therefore be inferior to it: it is then a greater thing to keep the law than circumcision, which was for its sake instituted. It hence follows, that the uncircumcised, provided he keeps the law, far excels the Jew with his barren and unprofitable circumcision, if he be a transgressor of the law: and though he is by nature polluted, he shall yet be so sanctified by keeping the law, that uncircumcision shall be imputed to him for circumcision. The word uncircumcision, is to be taken in its proper sense in the second clause; but in the first, figuratively, for the Gentiles, the thing for the persons. It must be added -- that no one ought anxiously to inquire what observers of the law are those of which Paul speaks here, inasmuch no such can be found; for he simply intended to lay down a supposed case -- that if any Gentile could be found who kept the law, his righteousness would be of more value without circumcision, than the circumcision of the Jew without righteousness. And hence I refer what follows, And what is by nature uncircumcision shall judge thee, etc., not to persons, but to the case that is supposed, according to what is said of the Queen of the south, that she shall come, etc., (Matthew 12:42,) and of the men of Nineveh, that they shall rise up in judgment, etc., (Luke 11:32) For the very words of Paul lead us to this view -- "The Gentile," he says, "being a keeper of the law, shall judge thee who art a transgressor, though he is uncircumcised, and thou hast the literal circumcision."

Therefore, if the uncircumcision - If those who are not circumcised, that is, the pagan.
Keep the righteousness of the law - Keep what the Law of Moses commands. It could not be supposed that a pagan would understand the requirements of the ceremonial law; but reference is had here to the moral law. The apostle does not expressly affirm that this was ever done; but he supposes the case, to show the true nature and value of the rites of the Jews.
Shall not his uncircumcision - Or, shall the fact that he is uncircumcised stand in the way of the acceptance of his services? Or, shall he not as certainly and as readily be accepted by God as if he were a Jew? Or in other words, the apostle teaches the doctrine that acceptance with God does not depend on a man's external privileges, but on the state of the heart and life.
Be counted for circumcision - Shall he not be treated as if he were circumcised? Shall his being uncircumcised be any barrier in the way of his acceptance with God? The word rendered "be counted," is what is commonly rendered "to reckon, to impute"; and its use here shows that the Scripture use of the word is not to transfer, or to charge with what is not deserved, or not true. It means simply that a man shall be treated as if it were so; that this lack of circumcision shall be no bar to acceptance. There is nothing set over to his account; nothing transferred; nothing reckoned different from what it is. God judges things as they are; and as the man, though uncircumcised, who keeps the Law, ought to be treated as if he had been circumcised, so he who believes in Christ agreeably to the divine promise, and trusts to his merits alone for salvation, ought to be treated as if he were himself righteous, God judges the thing as it is, and treats people as it is proper to treat them, as being pardoned and accepted through his Son.

Therefore if the uncircumcision, etc. - If the Gentile be found to act according to the spirit and design of the law, his acting thus uprightly, according to the light which God has afforded him, will be reckoned to him as if he were circumcised and walked agreeably to the law.

Therefore if the (q) uncircumcision keep the righteousness of the law, shall not his (r) uncircumcision be counted for circumcision?
(q) This is the figure of speech metonymy, and means "uncircumcised".
(r) The state and condition of the uncircumcised.

Therefore if the uncircumcision keep,.... These words are spoken hypothetically; if any such persons could be found among the Gentiles who keep the whole law of God; and can only be absolutely understood of such, who from a principle of grace act in obedience to the law; as in the hands of Christ, and who look to Christ as the fulfilling end of it, for righteousness; in whom they keep
the righteousness of the law perfectly:
shall not his uncircumcision be counted for circumcision? by this question it is suggested, that an uncircumcised Gentile, who keeps the law as in the hands of Christ, and under the influences of his Spirit and grace, and keeps it in Christ, is reckoned a circumcised person in a spiritual sense, and must be preferable to a circumcised Jew that breaks it.

Therefore if the uncircumcision keep the . . . law, &c.--Two mistaken interpretations, we think, are given of these words: First, that the case here supposed is an impossible one, and put merely for illustration [HALDANE, CHALMERS, HODGE]; second that it is the case of the heathen who may and do please God when they act, as has been and is done, up to the light of nature [GROTIUS, OLSHAUSEN, &c.]. The first interpretation is, in our judgment, unnatural; the second, opposed to the apostle's own teaching. But the case here put is, we think, such as that of Cornelius (Acts 10:1-48), who, though outside the external pale of God's covenant, yet having come to the knowledge of the truths contained in it, do manifest the grace of the covenant without the seal of it, and exemplify the character and walk of Abraham's children, though not called by the name of Abraham. Thus, this is but another way of announcing that God was about to show the insufficiency of the mere badge of the Abrahamic covenant, by calling from among the Gentiles a seed of Abraham that had never received the seal of circumcision (see on Galatians 5:6); and this interpretation is confirmed by all that follows.

If the uncircumcision - That is, a person uncircumcised. Keep the law - Walk agreeably to it. Shall not his uncircumcision be counted for circumcision - In the sight of God?
