Substitutionary atonement discussion

Kevin Powell provides a great concise critique of this difficult theology:

"When I was in seminary, my systematics prof noted that the bible does not have one theology of atonement. And all the theology it does provide is based on metaphor.

But what I find most troubling about SA specifically, other than divine blood lust, is how abusive it can be toward non-believers. In my wife's LCMS childhood church, the pastor would point to a crucifix and bellow: 'You're the reason Jesus is up there! It's YOUR sin that Jesus is dying for! Everytime you lie, cheat, or steal, you hammer another nail into Jesus' hands. That should be YOU up there in horrific pain. But Jesus is dying in your place.'"
