Contradiction with Matthew 5:17
Jesus states that he came not to destroy the law, but to fulfill it, which could be seen as differing from the decree in Acts 21:25 that gentiles should only follow a few specific restrictions.
Matthew 5:17: Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Contradiction with Romans 6:14
States that sin shall not have dominion because believers are not under the law, whereas Acts 21:25 gives specific legal instructions for Gentile believers.
Romans 6:14: For sin shall not have dominion over you: for ye are not under the law, but under grace.
Contradiction with Galatians 5:3
Mentioning that anyone who is circumcised is a debtor to the whole law, which seems contradictory to the minimal restrictions suggested for Gentiles in Acts 21:25.
Galatians 5:3: For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
Contradiction with Ephesians 2:15
Talks about abolishing the law of commandments contained in ordinances, contrasting with Acts 21:25, which suggests adherence to certain commandments.
Ephesians 2:15: Having abolished in his flesh the enmity, [even] the law of commandments [contained] in ordinances; for to make in himself of twain one new man, [so] making peace;
Contradiction with Galatians 2:16
States that a man is not justified by the works of the law, while Acts 21:25 provides guidelines reminiscent of law for Gentiles.
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.
Contradiction with Colossians 2:14
Describes blotting out ordinances against us, conflicting with the notion of specific ordinances laid out in Acts 21:25.
Colossians 2:14: Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
Contradiction with Hebrews 8:13
The notion of the old covenant waxing old and ready to vanish contrasts with the enforcement of specific restrictions for Gentiles in Acts 21:25.
Hebrews 8:13: In that he saith, A new [covenant], he hath made the first old. Now that which decayeth and waxeth old [is] ready to vanish away.
Paradox #1
The contradiction or inconsistency in Acts 21:25 could be seen in the different rules for Jewish and non-Jewish (Gentile) believers. While Jewish believers were expected to follow traditional laws, Gentile believers were given fewer restrictions. This difference in rules could be viewed as unfair or inconsistent, as it suggests different standards for different groups within the same faith community.
