If you've been taught Rome's official position on the sacraments, which are required for salvation, according to Rome, you were taught salvation by works.
Rome goes on to say if anyone denies this, let him be anathema.
Don't mean to make you feel this is an inquisition. If it were, you'd smell burning flesh (how Rome did it).
Kinda hard for someone to see the forest if they can’t see the trees.
