Contradiction with Galatians 5:2
This verse contradicts Genesis 17:23 by emphasizing that if one seeks righteousness through circumcision, Christ will not benefit them, whereas Genesis 17:23 depicts circumcision as a covenant with God.
Galatians 5:2: Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
Contradiction with Romans 2:29
This verse emphasizes that true circumcision is a matter of the heart, in the Spirit, not the physical act, contrasting the literal circumcision undertaken by Abraham in Genesis 17:23.
Romans 2:29: 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.
