Romans 11:19

A believing Gentile says that he can rejoice that the Jews did not believe, saying that their condemnation made room for the Gentiles. But the Jews were not condemned by God in order to let the Gentiles in. They condemned themselves by rejecting God's gift, …

"But if the firstfruits are holy, so is the lump; and if the root is holy, so are the branches. But if some of the branches were broken off, and you, though you were a wild olive, were grafted in among them and became a sharer in the root and the fatness of the olive tree, do not boast against the branches. But if you do boast, it is not you who bear the root, but the root you. You say then: The branches were broken off so that I might be grafted in. Well: they were broken off because of unbelief. But you stand by faith: do not be proud in your thinking, but fear. For if God did not spare the natural branches, neither will he spare you. Behold, then, the goodness and the severity of God: toward those indeed who fell, severity; but toward you, goodness, if you continue in goodness. Otherwise you too will be cut off, and they, if they do not continue in unbelief, will be grafted in. For God is able to graft them in again. For if you were cut out of the olive tree which is wild by nature, and contrary to nature were grafted into the good olive tree, how much more shall these, who are according to nature, be grafted into their own olive tree?" I do not know how those who come from the school of Valentinus and Basilides, failing to hear these things thus spoken by Paul, suppose that there is a nature of souls which is always saved and never perishes, and another which always perishes and is never saved: when Paul plainly says that the branches of the good olive tree were broken off because of their own unbelief, and stood in need of the vengeance of divine severity; and again that the branches of the wild olive — which among them is set down as a nature that is lost — were grafted into the root and fatness of the olive tree. But to those people, indeed, an easy answer may be given by these words. […]

"Thou wilt say then," he goes on, "The branches were broken off that I might be grafted in." Again he establishes, by way of objection, the opposite to the former position, to show that what he said before, he had not said as directly belonging to the subject, but to draw them to him. For it was no longer by their fall that salvation came to the Gentiles, nor was it their fall that was the riches of the world. Nor was it by this that we were saved, because they had fallen, but the reverse. And he shows that the providence in regard to the Gentiles was a main object, even though he seems to put what he says into another form. And the whole passage is a tissue of objections, in which he clears himself of the suspicion of hatred, and makes his language such as will be acceptable.

Here he proves that the Gentiles were not chosen in place of the Jews because the Jews sinned, but for the faith which the Gentiles displayed. So where he seems to cast down the Gentile, there he shows that the fall of the Jews was …

Then when he says, you will say then, he excludes an objection from the gentiles: first, he presents the objection; second, he excludes it from a consideration of divine justice, at well; third, he urges them to diligently consider God's judgments, at see then the …
