“Behold, I, Paul, say to you, that if you are circumcised, Christ will profit you nothing.” In the Gospel the Savior says to the disciples, “He who hears you hears Me. He who receives you receives Me” (Lk 10:16). And the Apostle bears witness, saying, “It is no longer I who live, but Christ lives in me” (Gal 2:20). Elsewhere he says, “Or do you seek a proof of Him Who speaks in me, that is, Christ?” (2 Cor 13:3).
By this it is shown quite clearly that what he now says, “Behold, I, Paul, say to you,” means that his words should be received not as Paul’s words, but as the Lord’s. For in the first epistle to the Corinthians he had already indicated this to you: “To those who are married I command, not I, but the Lord” (1 Cor 7:10). Immediately afterward he added, “But to the rest I command, I” (1 Cor 7:12). So that the obligation of his word might not appear slight, he says, “I think that I also have the Spirit of God.” Therefore, when both the Spirit and Christ speak in him, the one who speaks after the example of the prophets will not be despised: “Thus says the Lord Almighty.”
But what is said, “Behold, I, Paul, say to you: if you receive circumcision, Christ will profit you nothing,” will seem even greater if this word is connected with the beginning. There he says, “Paul, an Apostle, not from men nor through man, but through Jesus Christ,” and so forth. Thus the hearers are moved not so much by the greatness of the one sent as by the authority of Him Who sent him.
But someone may say, “This passage is contradicted by what is written to the Romans: ‘Circumcision indeed profits if you keep the Law’ (Rom 2:25), and below, ‘What advantage then has the Jew, or what is the profit of circumcision? Much in every way. First of all, that they were entrusted with the oracles of God’ (Rom 3:1-2). If Christ profits those who have been circumcised nothing, how does circumcision bring profit to people who keep the Law?”
This difficulty is resolved by the following answer. It is enough to say that the epistle addressed to the Romans was intended for those who had believed in Christ from Jews and Gentiles. This compelled the Apostle Paul not to offend either people. Since each people has its own advantage, he would neither subject the Gentiles to circumcision nor incline the Jews to retain the foreskin.
But when addressing the Galatians in his epistle, the Apostle uses another proof. For they were not among the circumcised, but among Gentiles who had believed. Circumcision could not profit them when, after the grace of the Gospel, they returned again to the beginnings of the Law.
In the Acts of the Apostles it is narrated that certain of the circumcised rose up, asserting that believers from the Gentiles must be circumcised and keep the Law of Moses. Then the elders in Jerusalem, and likewise the Apostles, gathered together and determined in writing that they should not be burdened with the yoke of the Law. They were to keep nothing more than to abstain from food sacrificed to idols, from blood, and from fornication, or, as it is written in some copies, from what is strangled.
So that no doubt might remain that circumcision brings no profit, and that only for the sake of believers from the Jews he softened his judgment about circumcision in the epistle to the Romans, he showed the truth as he approached the end little by little. He showed that neither circumcision nor uncircumcision has any power, saying, “Circumcision is nothing, and foreskin is nothing, but the keeping of the commandments of God” (1 Cor 7:19).
Circumcision is so nothing that it does not help even the house of Israel, which boasted in circumcision. The prophet also shows this: “All the nations are uncircumcised in the flesh, and the house of Israel is uncircumcised in heart” (Ezek 44:9). Likewise the uncircumcised Melchizedek blessed the circumcised Abraham (Gen 14:19).
For the words, “If you are circumcised,” have such a meaning that he seems to say, “If you are circumcised in the flesh.” Elsewhere he calls this not circumcision, circumcisio, but mutilation, concisio, saying, “Beware of the mutilation, concisio; for we who serve God in spirit are the circumcision, sumus circumcisio, and glory in Christ, and do not trust in the flesh” (Phil 3:2-3).
He does not trust in the flesh who expects every profit for himself from Christ. He does not sow in the flesh, so as to know corruption from the flesh, but sows in the spirit, from which eternal life comes. The Apostle’s words, “If you are circumcised, Christ will profit you nothing,” must be examined more subtly. They mean not only that, if they are circumcised, circumcision itself does not profit them. Even if, apart from circumcision, they seem to have other virtues, nevertheless they will perish altogether when they are circumcised after faith in Christ.
What then? Did circumcision not help Timothy? Very much in every way. For he was circumcised not so much in order to receive any advantage from circumcision itself, as in order to gain others (1 Cor 9:19-23). He became a Jew to the Jews, in order by his own circumcision to lead the Jews to faith in Christ. But in reality it helps nothing when it is thought to bring some profit by itself.
