1. 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.
