This question has been raised before, and I sort of remember reading it, but I can’t seem to find it on the search, so I’ll ask my own version:
Mortal sin requires three elements: full knowledge, grave matter, and free consent. If any one of these 3 elements is missing, there is no mortal sin.
Based on that, wouldn’t it be true that there is essentially no such thing as mortal sin for anyone other than Catholics? Can’t one argue that, since he isnt Catholic, his church doesnt teach mortal sin (OSAS) and therefore he did not have full knowledge?
For example: if a Catholic masturbates, and he does so knowing it’s a mortal sin, and consents freely to doing it, he has indeed committed a mortal sin. But a Protestant, who has been taught that NOTHING can cause him to lose his salvation, freely decides to masturbate, thinking that it doesnt affect his salvation. Has he committed mortal sin?
Or does “full knowledge” refer to the fact that something is a “big sin” not necessarily that a particular sin can make you lose salvation?
Is it much more dangerous to be Catholic than Protestant?
