John Chrysostom
After saying, "But if you are a breaker of the law," he added, "your circumcision has become uncircumcision."
Having proved that he is uncircumcised, he finally pronounces judgment upon him without fear.
"If, then, the uncircumcised man keeps the righteous requirements of the law, will not his uncircumcision be counted as circumcision?"
See what the Apostle does. He does not say that uncircumcision surpasses circumcision. That would have been very grievous to his listeners at that time.
Rather, he says that uncircumcision has become circumcision.
Then he considers what circumcision is and what uncircumcision is. He says that circumcision is a good deed, and uncircumcision is an evil deed.

After this, by including the uncircumcised man who has good deeds in the concept of circumcision, and excluding the circumcised man who remains in a corrupt life, he gives the advantage to the uncircumcised man.
He no longer speaks of an uncircumcised man, but passes to the act itself, uncircumcision. He says: "Will not his uncircumcision be counted as circumcision?"
Again here he did not say, "will it be acknowledged," but "will it be counted as circumcision," which is far more expressive.
Likewise above he did not say, "your circumcision is counted as uncircumcision," but "has become uncircumcision" (Rom 2:25).
