Contradiction with Acts 16:3
This verse states that Paul circumcised Timothy, which contradicts Galatians 5:2 where Paul warns against circumcision as necessary for salvation.
Acts 16:3: Him would Paul have to go forth with him; and took and circumcised him because of the Jews which were in those quarters: for they knew all that his father was a Greek.
Contradiction with Acts 21:21
This passage reports that Paul was accused of teaching Jews not to circumcise their children, contrary to Galatians 5:2 where he advises Gentiles against circumcision.
Acts 21:21: And they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake Moses, saying that they ought not to circumcise [their] children, neither to walk after the customs.
Contradiction with Romans 3:1-2
Here, Paul speaks of the advantages of being a Jew and the value of circumcision, which contrasts with Galatians 5:2 where he advises against it.
Romans 3:1-2: What advantage then hath the Jew? or what profit [is there] of circumcision?
Contradiction with Romans 14:5
This verse promotes individual belief in practices, which contrasts with the strong warning in Galatians 5:2 against circumcision.
Romans 14:5: One man esteemeth one day above another: another esteemeth every day [alike]. Let every man be fully persuaded in his own mind. [fully persuaded: or, fully assured]
Contradiction with 1 Corinthians 7:18
Paul advises that one should remain in the state they were called, whether circumcised or not, which provides a more neutral stance than Galatians 5:2 suggests.
1 Corinthians 7:18: Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised.
Contradiction with Philippians 3:3-5
Paul describes himself as having reasons for confidence in the flesh, being circumcised, which contrasts with advising against circumcision in Galatians 5:2.
Philippians 3:3-5: For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
Paradox #1
Galatians 5:2 might seem to conflict with the emphasis on following the law in the Old Testament, particularly the practice of circumcision. This verse highlights faith in Christ over adherence to the law, which can appear contradictory to the earlier teachings where following the law was essential for righteousness.
Paradox #2
The contradiction or inconsistency might arise from the emphasis on faith versus works. Galatians 5:2 stresses faith in Christ over following specific laws, like circumcision. Some might see a conflict with other parts of the Bible where following the law or doing good deeds is emphasized as part of faith.
