ACC ~ Romans 4 v12

THE FATHER OF THE FAITHFUL. ORIGEN: After believing, Abraham received circumcision as a sign of the faith which he already had … which is how he can also be the father of those who are circumcised, provided that they share the same faith which he had while he was still uncircumcised. COMMENTARY ON THE EPISTLE TO THE ROMANS.

AMBROSIASTER: Paul says this because Abraham by believing became the forefather of the circumcision, but of the heart, not only of those who descended from him but also of those who, from among the nations, believed in the way he did. He is the father of the Jews according to the flesh, but according to faith he is the father of all believers. COMMENTARY ON PAUL’S EPISTLES.

THE REALITY OF WHICH THE SIGN SPOKE. CHRYSOSTOM: Circumcision is meaningless if there is no faith within. It is a sign of righteousness, but if there is no righteousness, then there is no sign either. The reason the Jews received a sign was that they might seek diligently for the reality of which the sign spoke. If they had done so, they would not have needed the sign in the first place. Righteousness is not the only thing that circumcision proclaims; it also proclaims that righteousness can be found in an uncircumcised man (e.g., Abraham). In effect, therefore, circumcision proclaims that there is no need of circumcision. HOMILIES ON ROMANS 8.

THE FATHER OF THE RIGHTEOUS. PELAGIUS: Therefore all the Gentiles who believe are children of Abraham when faith alone is credited to them as righteousness and they too receive the circumcision—of the heart. Or perhaps this verse should be understood like this: Abraham was righteous in uncircumcision so that he could become the father of uncircumcised believers, and he remained righteous once he was circumcised in order to become the father of the righteous who are circumcised. PELAGIUS’S COMMENTARY ON ROMANS.

PREPARED FOR SALVATION BY FAITH. THEODORET OF CYR: If a Gentile who has not been circumcised follows Abraham’s faith, which he manifested before being circumcised, he will not be rejected. For the God of all, since he had foreseen as God that he would gather one people from both Jews and Gentiles and prepare for them salvation by faith, had appointed Abraham as their father as well. Paul had demonstrated that Abraham had acquired righteousness by faith before being circumcised and that even after being circumcised he lived not according to the law of Moses but by clinging to his faith. Hence Paul called him the father of the Gentiles who believe. INTERPRETATION OF THE LETTER TO THE ROMANS.
