Galatians 3:10-11
For all who rely on works of the law are under a curse; for it is written, “Cursed be everyone who does not abide by all things written in the Book of the Law, and do them.” Now it is evident that no one is justified before God by the law, for “The righteous shall live by faith.”
Galatians 3:10-11 is Catholic teaching, mom dearest. We are not saved by the works of the law. We are saved by works of faith and love.
