Food for Your Theo-Political Appetite

I'm more interested in the prayer/presence of God stuff that has come up, but I figured I'd go ahead and recommend a resource for the political/capital punishment/church/kingdom theme that has been going on. I can't find the text available online, otherwise I'd link it. Anyway, it is Martin Luther's "On Governmental Authority." This is a very influential document in Christian political theory. I read it in Hans Hilerbrand's "Protestant Reformation," a collection of original sources from the period. Check it out. For those at Ozark the call # is 270.6 H652p. Let me know your thoughts.
