Contradiction with Romans 3:28
This verse emphasizes justification by faith without the deeds of the law, in contrast to Paul participating in a purification ritual.
Romans 3:28: Therefore we conclude that a man is justified by faith without the deeds of the law.
Contradiction with Galatians 5:2-4
These verses warn that adherence to the law nullifies Christ's benefit, contradicting Paul's involvement in a law-related ritual.
Galatians 5:2-4: Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
Contradiction with Colossians 2:16-17
These verses advise against letting others judge by the law, suggesting freedom from such observances, unlike the purification act.
Colossians 2:16-17: Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath [days]: [in meat...: or, for eating and drinking] [respect: or, part]
Contradiction with Hebrews 10:1
This verse states the law is a shadow of good things to come, while Acts 21:26 describes participation in a law-based ritual.
Hebrews 10:1: For the law having a shadow of good things to come, [and] not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
Contradiction with Galatians 2:16
This verse teaches that a person is justified by faith and not by observing the law, contrary to Paul's purifying himself according to the law's requirements.
Galatians 2:16: Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
Paradox #1
The contradiction or inconsistency in Acts 21:26 could be seen in the context of following old religious traditions while preaching a new faith. It might appear contradictory for someone promoting freedom from the law to still adhere to traditional rituals, potentially confusing followers about the need to maintain old practices when embracing new beliefs.
