I have just come across the sermon entitled A Sonrise Story by Paul J. Nuechterlein which does an excellent job of explaining how Girardian non-violence fits into the story of salvation.
Not a sermon I could preach to my congregations! Nevertheless, I think it explains some Girardian ideas in a more accessible way than either Girard himself or most Girardian theologians.
I particularly like the explaination of mimetic theory at the beginning of the sermon. Nuechterlein manages to explain mimesis in a way that I've been striving to do for awhile.
