Bible Verses About Circumcision: A seal of righteousness

For circumcision, indeed, doth profit, if law thou mayest practise, but if a transgressor of law thou mayest be, thy circumcision hath become uncircumcision.

If, therefore the uncircumcision the righteousness of the law may keep, shall not his uncircumcision for circumcision be reckoned?

and the uncircumcision, by nature, fulfilling the law, shall judge thee who, through letter and circumcision, art a transgressor of law.

For he is not a Jew who is so outwardly, neither is circumcision that which is outward in flesh;

but a Jew is he who is so inwardly, and circumcision is of the heart, in spirit, not in letter, of which the praise is not of men, but of God.
