Deeds demonstrate the reality of your faith. But, it earns NOTHING in the eyes of God. Our salvation is purely the grace of God, and of works.
So as a pastor, if you have congregant who by faith finds Christ but stops attending Sunday service, and says it's unnecessary to read the Bible, you are going to tell him . . .?
Our salvation is purely the grace of God, and (not) of works.
I don't understand why you think this is different than Catholic teaching. All the work was done by Christ. Obviously, though there are positive commands that He gave us to follow "go ye thereforth" "take this all of you and eat it" "not forsaking the assembly of ourselves (via Paul)" etc., and of course love God and love your neighbor.
