Catechesis: Good Works

Here we must take great care not to draw works into the article of justification and salvation and mix them with it. Therefore it is proper to reject the propositiones that good works are necessary for the salvation of believers and that it is impossible to be saved without good works. For these [propositions] are totally contradictory to the teaching on the exclusive clauses in the article of justification and salvation, that is, they oppose St. Paul’s expressions that completely exclude our works and merits from justification and ascribe everything to God’s grace and Christ’s merit alone.—FC SD IV:22
