Romans 2:25-3:8 Revised Standard Version (RSV)
25 Circumcision indeed is of value if you obey the law; but if you break the law, your circumcision becomes uncircumcision. 26 So, if a man who is uncircumcised keeps the precepts of the law, will not his uncircumcision be regarded as circumcision? 27 Then those who are physically uncircumcised but keep the law will condemn you who have the written code and circumcision but break the law. 28 For he is not a real Jew who is one outwardly, nor is true circumcision something external and physical. 29 He is a Jew who is one inwardly, and real circumcision is a matter of the heart, spiritual and not literal. His praise is not from men but from God.
3 Then what advantage has the Jew? Or what is the value of circumcision? 2 Much in every way. To begin with, the Jews are entrusted with the oracles of God. 3 What if some were unfaithful? Does their faithlessness nullify the faithfulness of God? 4 By no means! Let God be true though every man be false, as it is written,
“That thou mayest be justified in thy words,
5 But if our wickedness serves to show the justice of God, what shall we say? That God is unjust to inflict wrath on us? (I speak in a human way.) 6 By no means! For then how could God judge the world? 7 But if through my falsehood God’s truthfulness abounds to his glory, why am I still being condemned as a sinner? 8 And why not do evil that good may come?—as some people slanderously charge us with saying. Their condemnation is just.
