Contradiction with John 3:16
Declares salvation through belief in Jesus, not through righteousness obtained by faith as in 2 Peter 1:1.
John 3:16: For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
Contradiction with Ephesians 2:8-9
States salvation is by grace through faith, and not of works, contradicting the notion of righteousness obtained by faith through works in 2 Peter 1:1.
Ephesians 2:8-9: For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God:
Contradiction with James 2:24
Emphasizes justification by works and not by faith alone, in contrast to 2 Peter 1:1 which highlights righteousness obtained through faith.
James 2:24: Ye see then how that by works a man is justified, and not by faith only.
Contradiction with Galatians 2:16
Asserts that a person is not justified by works of the law but by faith in Jesus, diverging from the faith-as-righteousness path delineated in 2 Peter 1:1.
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 Romans 3:28
Argues for justification by faith apart from works of the law, contrasting with the righteousness conferred by faith mentioned in 2 Peter 1:1.
Romans 3:28: Therefore we conclude that a man is justified by faith without the deeds of the law.
