Faith is expressed through works. Even faith itself is a kind of work, an inner work. What Protestants originally rejected were barbarisms like selling indulgences, and people forgetting that all work is fueled by grace - no one does anything on their own.
Okay. Indulgences haven’t been “sold” since the 1550’s (or before), and it’s Catholic dogma that only works done with the aid of grace are meritorious in any sense.
