The End of Barbarism

I think this article at Progression of Faith is at least one good answer to how Christianity can once again address society in a thoughtful and meaningful way and simultaneously divest itself of the one thing in Christian theology that does not resonate with reasoned and intelligent folk everywhere. If it is true at all, isn't it best to re-work the Gospel toward a higher vision for society, beginning with the doctrine of "atonement," and prevent religion from bringing society down to its lowest common denominator: violence? What do you think?
