Contradiction with Romans 3:28
This verse emphasizes justification by faith without deeds of the law, which might contrast with the transformation theme in Romans 6:4.
Romans 3:28: Therefore we conclude that a man is justified by faith without the deeds of the law.
Contradiction with Galatians 2:16
This verse stresses that a person is not justified by works of the law, which may seem at odds with the new life of righteousness implied in Romans 6:4.
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.
