John Chrysostom
"For we say that faith was reckoned to Abraham as righteousness" (Rom. 4:9). Above, referring to Scripture, the Apostle said: "For what does Scripture say? Abraham believed God, and it was reckoned to him as righteousness" (Rom. 4:3). Here he proposes another point and affirms that righteousness existed in uncircumcision. Then he resolves the new objection arising from this: if Abraham was justified while uncircumcised, why was circumcision introduced?
