If Jesus on the cross actually is God on the cross, and if God on the cross is Godforsaken, if God comes to the cross to feel what it's like to be us at our most human, then what if the cross is also God's mea culpa?
Atonement theology says, "Jesus died so we might live." It suggests that the torture and murder lamented this Friday is "good."
I think that there is something powerful in simply considering Christ as a criminal defendant. That subtle change in perspective can change worlds.
