John Chrysostom — on Rom 9:4-5 (Homily on Romans 16)

“"To whom pertaineth the adoption, and the glory, and the covenants, and the giving of the Law, and the service of God, and the promises; whose are the father's, and of whom as concerning the flesh Christ came, Who is over all, God blessed for ever. Amen." And what is this? one asks. For if with a view to the belief of others he was willing to become accursed, he ought to have also wished for this in the Gentiles' behalf. But in fact if he had prayed for the Gentiles only, this would not have been equally clear. But since it is for the Jews only, it is a clear proof that it is only for Christ's glory that he is thus earnest. For what he means is something of this kind: all were talking and accusing God, that after being counted worthy of the name of sons, and receiving the Law, and knowing Him beyond all men, and enjoying such great glory, and serving him beyond the whole world, and receiving the promises, and being from fathers who were His friends, and what was the greatest thing of all, having been forefathers of Christ Himself (for this is the meaning of the words, "of whom, as concerning the flesh, Christ came"), they are now cast out and disgraced; and in their place are introduced men who had never known Him, of the Gentiles. Now since they said all this, and blasphemed God, Paul hearing it, and being cut to the heart, and vexed for God's glory's sake, wished that he were accursed, had it been possible, so that they might be saved, and this blasphemy be put a stop to, and God might not seem to have deceived the offspring of those to whom He promised the gifts.”
