It would, by definition include those who rely on, or presume, pardon of his/her sins without repenting of them. This can also include Catholics of course.
I don't think this a null set. I think could also include those who believe all their sins (past, present and future) are already forgiven. And there could be some overlap logically with those holding to OSAS belief.
Now you’ve done it — you’veintroduced OSAS! Whatever you do, don’t mention Mary — OOPS!
