The difference I was thinking of was that there's no difference or one can't, in some ways, distinguish a difference. If my real sinfulness is the result of the fact that I act sinful out of a feeling that I'm no good, and I think that's just exactly how somebody who feels sinful does act, or has a continual urge to act, then if he is forgiven by some outside source and really feels forgiven, then that impulse, compulsion, or magnitizing idea ceases to exist. There would follow the feeling of grace. On the other hand, if through psychoanalysis, for example, a person is able to discover within him or herself the final core experience in which a false feeling of sinfulness was inculcated and expose it as a lie, there might follow an experience of liberation, a sureness that one is OK. Naturally the latter would imply that something about the notion of original sin is ascue, or goofy. That might be that the notion of the corrupting knowledge granted by eating the apple of the tree of knowledge is corrupting, and universally or originally so, only because knowledge of a thing, out linguistic capacity categorize, create duality, to is not the thing itself. Words about the now are not the now. Sin is separation that had its origin in language. Whether you call it separation from God, the Self, or Being is pretty much just semantic, if you ask me.
I guess if somebody wanted to know what I think is the important point to take away from the question posed by this thread is that, one way or the other, we are either forgiven or there's nothing wrong with us. It would be nice to know it.
