The death and resurrection of Christ allow Christians to put a targeting system on our bows. I don't view sin as a commodity that's bought and sold; that's an interpretation of the Western churches that, to my knowledge, is not held by the Orthodox. Theoria is so much more hopeful and worthy than the repugnant "total depravity" of Calvinism.

We miss the mark. Christ doesn't magically wave away all we've done; He lets us try again. Christians hold that we're made in the image of God. It's a pity they view that image with such contempt.

Universal salvation has been posited since Origen, by the way, so you might want to read up on that before casually dismissing it as a new, meaningless thing. Personally, I worship God out o thanksgiving and not fear, and I find the relationship to be liberating, rewarding, and holy. But I'm a young Episcopalian.
