This site contains a number of interesting looking articles, some of which are unpublished, by the likes of Cavanaugh, Ellul, Hauerwas, Milbank,Yoder, Mccarthy-Matzko. This is the blurb:
The library contains radical and subversive writings by several prominent Christian theologians.The work here reflects the alien nature of following Christ, and being a people in exile, "living out of control". These theologians are challenging the standard reading of the bible and Christ presented in todays mainstream establishments. Their writings are uncompromising and threatening to the cheap theology characteristic of the North American Church.
If you are interested in radical, political theology (and even if you aren't but think you ought to be) then go and take a browse. H/T Ben Myers.
