"For he is not a Jew, which is one outwardly; neither is that
circumcision, which is outward in the flesh: But he is a Jew, which is one inwardly;
and circumcision is that of the heart, in the spirit, and not in the letter; whose praise
is not of men, but of God." Romans 2:25-29. (for more Bible references, click here)
"As many as desire to make a fair shew in the flesh, they
constrain you to be circumcised; only lest they should suffer persecution for the cross of
Christ. For neither they themselves who are circumcised keep the law; but desire to have
you circumcised, that they may glory in your flesh." Galations 6:12-13. (for
