I've just finished John Howard Yoder's The Politics of Jesus. It was an excellent read, and I'll probably re-read it with blog responses soon.
I have been in orbit around this work for a long time, so it is nice to have finally touched down. I first encountered Yoder through Hays' The Moral Vision of the New Testament and then of course through Hauerwas. What's great about Yoder is that he argues his points exegetically, so Biblical studies people like myself feel right at home. I also found that Yoder lays down an excellent via media between Christian anarchism and Constantinianism. He also embraces Romans 13 as a central plank of pacifism, not an apologetic text.
