Major doctrine...changing one word destroys the doctrine of the faith of Jesus Christ. Christ had faith, perfect faith even unto the death of the cross. The new versions switch the story around to man's faith justifies.
I am proud to say that Jesus Christ is the Just and the Justifier of them that believe!
Galatians 2:16
KJV 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.
ESV 16 yet we know that a person is not justified by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified.
