Contradiction with Romans 2:25
This verse emphasizes the value of circumcision if one keeps the law, seemingly contradicting the idea in Galatians 6:15 that neither circumcision nor uncircumcision matters.
Romans 2:25: For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
Contradiction with 1 Corinthians 7:18-19
Here, Paul states that circumcision is nothing and uncircumcision is nothing, which might seem to contrast with Galatians 6:15 since yet another focus is placed on these external practices.
1 Corinthians 7:18-19: Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised.
Contradiction with Deuteronomy 10:16
This verse commands the Israelites to circumcise their hearts, suggesting the importance of spiritual transformation, which at first glance appears to elevate the law, potentially at odds with the message of new creation in Galatians 6:15.
Deuteronomy 10:16: Circumcise therefore the foreskin of your heart, and be no more stiffnecked.
Contradiction with Genesis 17:10-11
God commands Abraham and his descendants to practice circumcision as a covenant sign, which could be seen as contradictory to Galatians 6:15's message about the irrelevance of circumcision in Christ.
Genesis 17:10-11: This [is] my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised.
