We don't grade sin. That seems to be a RC thing.
I can't find that "mortal" thing anywhere in the bible. Maybe you can point it out to me.
Strange, I can't find that "Bible" thing anywhere in the Bible, either.
'Tis.
I seem to remember that a sin against the Holy Spirit was unforgiveable. Still think sins don't have grades?
1 John 5:16-17What is Mortal Sin?"If anyone sees his brother sinning, if the sin is not deadly, he should pray to God and he will give him life. This is only for those whose sin is not deadly. There is such a thing as deadly sin [mortal sin], about which I do not say that you should pray. All wrongdoing is sin, but there is sin that is not deadly [venial sin]."
