Paradox #1
The contradiction or inconsistency linked to Galatians 2:15 might revolve around differing views on the Law of Moses and its applicability to non-Jewish Christians. In early Christianity, there was a debate about whether Gentile converts needed to follow Jewish laws to be part of the Christian community. This verse is part of a broader discussion where Paul argues for faith in Jesus rather than adherence to the law, which was a significant shift from Jewish traditions and created tension among early Christians.
