Let's seperate this.
Ah, but according to Catholicism, you must maintain good works for your justification.
According to Calvinism, a believer can do anything he wants? Sin and enjoy life to the fullest, cause it matters not a whit what one does. Right?
We both know that any profession of faith without a resulting change in attitude and behavior is false and not salvific. We are at least honest that a believer must walk the walk and not just talk the talk.
One can not walk off the path and insist one is still heading for the path's destination.
which are evidently apart from the Law - though I don't know which good works are contrary to the Law.
You have studied under OP well. You also fail to understand the difference between being "contray" to the Law and just being not "under" the law. Good works are good not because the Law says so, but because they are. The Law is a tutor, unnecessary now that we have Christ. What Christians do that is good is totally "apart" from the Law. They have no relation to the law. But that doesn't make the works "contrary" to the Law.
