John Chrysostom
Again he sets forth the opposite of what preceded in the form of an objection. He shows that what he had said shortly before was spoken with no other intention than to attract the Jews. The salvation of the Gentiles did not occur because of the Jews’ trespasses. Nor is their trespass itself the riches of the world. Likewise, we were not saved because they fell, but quite the contrary. The Apostle shows God’s special providence concerning the Gentiles, although the words seem to express something else. He sets forth this whole passage as an objection, freeing himself from suspicion of hostility and making his speech more readily acceptable.
