Gee... that's not much of a definition. The first part is not possible and therefore of no consequence and the second part is not logically possible as God is immutable. That doesn't leave us with much.
It was an answer though ..
Got to type fast... on a ship with lousy internet.
I wouldn't have known sin to be such a horror except in the fact that it opposes God. I suppose Satan to be the first, and, furthermore, the only one with his ability to govern spirits for evil, as permitted by God (for God's purposes); I take Satan therefore to be the author of it, yet, as caused by God.
Btw, thanks for the PM, and I can sympathize. But I try, as much as I reasonably can, to work with what I think people mean, when they say a thing, instead of always fighting over the definition. I do, often, try to correct terminology and uses of words when I see a word taking what someone meant and sloughing it into confusion. (We humans do have a way of letting our own words, even when carefully chosen, influence what we think.)
Hamartiology is a very interesting subject. I find sin to be different from anything else, and knowing that God cannot be injured by anything from outside himself, somehow doesn't change the fact that sin bruised his heel. And I have ideas, but I don't know what that means. A lot of speculation there. For something purportedly a non-thing, sin is described in the Bible in a couple of places, as something almost of its own person,
"...sin crouches at your door. It desires to have you..."; "He became sin for us." But I expect the explanation will be simpler and deeper than we can know at present.
