since indeed there is one God who will justify the circumcised by faith and the uncircumcised through faith.
ExplanationCommentary
Verse 30. God who justifieth circumcision, and also the uncircumcised by faith; that is, by the faith and religion of the new law, or by a faith working by charity, and joined with good words proceeding from faith. See the Council of Trent, Sess. 6. cap. viii. “When the apostle says, that a man is justified by faith, and gratis, according to the perpetual consent of the Catholic Church, we are said to be justified by faith, because faith is the beginning and foundation of man’s salvation, and the root of his justification, without which we cannot please God, nor be made his sons; and we are said to be justified gratis, because nothing of those things which go before justification, whether faith or works, are meritorious of the grace of justification.” Witham.
