Though Paul has clearly proved that bare circumcision brought nothing to the Jews, yet since he could not deny but that there was some difference between the Gentiles and the Jews, which by that symbol was sealed to them by the Lord, and since it was inconsistent to make a distinction, of which God was the author, void and of no moment, it remained for him to remove also this objection. It was indeed evident, that it was a foolish glorying in which the Jews on this account indulged; yet still a doubt remained as to the design of circumcision; for the Lord would not have appointed it had not some benefit been intended. He therefore, by way of an objection, asks, what it was that made the Jew superior to the Gentile; and he subjoins a reason for this by another question, What is the benefit of circumcision? For this separated the Jews from the common class of men; it was a partition-wall, as Paul calls ceremonies, which kept parties asunder.

What advantage - The design of the first part of this chapter is to answer some of the objections which might be offered by a Jew to the statements in the last chapter. The first objection is stated in this verse. A Jew would naturally ask, if the view which the apostle had given were correct, what special benefit could the Jew derive from his religion? The objection would arise particularly from the position advanced Romans 2:25-26, that if a pagan should do the things required by the Law, he would be treated as "if" he had been circumcised. Hence, the question, "what profit is there of circumcision?"

Jew. What advantage then hath the Jew? Or what profit is there of circumcision? - As if he had said: You lately allowed, (Romans 2:25), that circumcision verily profited; but if circumcision, or our being in covenant with God, raises us no higher in the Divine favor than the Gentiles; if the virtuous among them are as acceptable as any of us; nay, and condemn our nation too, as no longer deserving the Divine regards; pray tell me, wherein lies the superior honor of the Jew; and what benefit can arise to him from his circumcision, and being vested in the privileges of God's peculiar people?

What (1) advantage then hath the Jew? or what profit [is there] of circumcision?
(1) The first address to the Jews, or the first anticipating of an objection by the Jews: what then, are the Jews preferred no more than the Gentiles? Indeed, they are, says the apostle, by the doing of God, for he committed the tables of the covenant to them, so that the unbelief of a few cannot cause the whole nation without exception to be cast away by God, who is true, and who also uses their unworthiness to commend and set forth his goodness.

What advantage then hath the Jew?.... If he is not properly a Jew, who is born of Jewish parents, and brought up in the customs, rites, and religion of the Jewish nation, but anyone of whatsoever nation, that is born again of water, and of the Spirit; where is the superior excellency of the Jew to the Gentile? A man may as well be born and brought up a Heathen as a Jew; the one has no more advantages than the other by his birth and education: it may be rendered, "what hath the Jew more?" or "what has he superfluous" or "abundant?" the phrase answers to the Hebrew in Ecclesiastes 1:3, which is rendered, "what profit hath a man?" and in Ecclesiastes 6:8, , "what hath a wise man more", &c. and in Romans 3:11, , "what is a man better?" the first of these passages the Septuagint render by , "what abundance?" and the last by "what more", or "superfluous", or "abundant?" the phrase used by the apostle here:
or what profit is there of circumcision? since that which is outward in the flesh profits not unless the law is kept, otherwise circumcision is no circumcision; and if an uncircumcised Gentile keeps the law, he is a better man than a circumcised Jew; yea, he judges and condemns him; for the only true circumcision is internal, spiritual, and in the heart. To this the apostle answers in the Romans 3:2.

The law could not save in or from sins, yet it gave the Jews advantages for obtaining salvation. Their stated ordinances, education in the knowledge of the true God and his service, and many favours shown to the children of Abraham, all were means of grace, and doubtless were made useful to the conversion of many. But especially the Scriptures were committed to them. Enjoyment of God's word and ordinances, is the chief happiness of a people. But God's promises are made only to believers; therefore the unbelief of some, or of many professors, cannot make this faithfulness of no effect. He will fulfil his promises to his people, and bring his threatened vengeance upon unbelievers. God's judging the world, should for ever silence all doubtings and reflections upon his justice. The wickedness and obstinate unbelief of the Jews, proved man's need of the righteousness of God by faith, and also his justice in punishing for sin. Let us do evil, that good may come, is oftener in the heart than in the mouth of sinners; for few thus justify themselves in their wicked ways. The believer knows that duty belongs to him, and events to God; and that he must not commit any sin, or speak one falsehood, upon the hope, or even assurance, that God may thereby glorify himself. If any speak and act thus, their condemnation is just.

JEWISH OBJECTIONS ANSWERED. (Romans 3:1-8)
What advantage then hath the Jew?--that is, "If the final judgment will turn solely on the state of the heart, and this may be as good in the Gentile without, as in the Jew within, the sacred enclosure of God's covenant, what better are we Jews for all our advantages?"
Answer:

What advantage then hath the Jew? In the second chapter Paul has shown that the Jews as well as the Gentiles are included under sin, and that the possession of the law and the rite of circumcision were of no avail unless the law was kept faithfully. In this chapter the Jew is supposed to object to this conclusion; his objections are presented, and answered. The first is, "What advantage is it then to the Jew to have the law and the rite of circumcision at all, if all, both Jew and Gentile, will be judged on the same principles in the judgment day?" The second verse gives the answer.
Much every way. The Jew had great advantages. He had greater light, more knowledge, better privileges, higher honors. The greatest advantage was that they had the oracles of God, the Holy Scriptures, and hence the promises which revealed a Messiah of mankind. This was not the only advantage, but the first.
What if some did not believe? In this verse the Jew raises a second objection. God has made a promise to Abraham to be a God to him and to his seed in all generations. "Shall God's faithfulness be made of none effect, his promise be broken, because a great part of Israel does not believe upon the promised Seed of Abraham, who was to bless all nations?" God forbid. The Greek means, literally, "Not so." It does not follow that God is unfaithful, because he rejects unbelieving Israel, for his covenant with Israel and his promise to Abraham were conditional.
Let God be true, but every man a liar. That is, Let us believe all men to have broken their word, rather than God his.
As it is written. Psalm 51:4. One of the penitential psalms, in which David mourns over his own sins. God's sayings, his threatenings, are justified by his judgments. They were in the case of David. They were also in the rejection of the Jewish nation, in spite of the promise, when it had rejected the Holy One of Israel.

What then, may some say, is the advantage of the Jew, or of the circumcision - That is, those that are circumcised, above the gentiles?
