Blessed Paul was appointed a minister of the divine Gospel (cf. Rom 1:1), and he proclaimed Christ to the Gentiles. Everywhere he said that those who came from the blood of Israel had fallen away.
He also affirmed that those once in demonic darkness had become servants called according to God's preordination and foreknowledge. Therefore he spoke a necessary word in his defense.
He did this lest any untaught person think that he was almost trampling on the fallen of Israel's race and mocking those who had stumbled. He says, "I speak the truth in Christ, I do not lie," and what follows.
Yet one may grieve over those who reached such folly that they departed from love for God, and then suffered punishments for it. It would not be without reason to shed tears for them out of kindred love.
Rather, in this lies the fullness of love. But for a man to desire that he himself be separated from Christ for them is already beyond love.
No one, if he is of sound mind, would dare to oppose God for the salvation of others. Nor would he count his own life as nothing, while preferring that it should belong to others.
What, then, does he mean by offering his own salvation as a ransom for the salvation of the Jews? Clearly, this speech is hyperbolic and contains a declaration of the most perfect love.
"I could wish," he says, "that I myself were accursed from Christ for my brethren, my kinsmen according to the flesh." It is as though he were saying this.
"If Israel were to be saved again through my opposition to Christ, I myself would choose to take upon myself so terrible an evil. I would go alone to destruction for all."
"I am the one who said to those justified by faith, 'For I determined not to know anything among you except Jesus Christ and Him crucified' (1 Cor 2:2)."
"I am the one who proclaims to all, 'Who shall separate us from the love of God? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?' (Rom 8:35)."
By this he was catching the Jews into obedience, and he was repelling the slander of the senseless. For some of the Jews thought that the divine Paul had lost his mind and opposed the laws given through Moses.
For this reason, writing to those who believed, he said, "For if we are beside ourselves, it is for God; if we are of sound mind, it is for you" (2 Cor 5:13).
Thus, he says, I would most gladly prefer to be separated from Christ, if only I might again save those who came from the blood of Israel.
Nor does he stop here. He shows, as it were, that the cause of his grief for them is by no means slight. It could produce in him such a disposition that this statement would not seem burdensome or absurd to him.
He could say that he offers his own life as the ransom for the life of others. For first of all, he says, they are Israelites. To them belong adoption, glory, and the covenants.
From them, according to the flesh, is Christ Himself. If they had been among those who only recently came to know Him who is God by nature and in truth, his grief might have been more moderate.
So too, if they had not possessed the Law given through Moses, which crowned them with nearness to Him, his grief might have been less. If they had not sprung from the root of the holy fathers, it might have been less.
If they had not been appointed heirs of their glory, and if they had not first been instructed in the ways of serving God, sorrow over them could have become more restrained.
But if these are their fathers, and the other things are theirs as well, then their calamity is truly dreadful. For when their affairs were almost carried by a favorable wind, they swerved toward an unexpected end.
They did not attain what they hoped for. Is not what happened to these wretched ones truly terrible?
