Good Ways And Bad Ways

If this review does it justice at all, Robert Benne's Good Ways and Bad Ways to Think About Religion and Politics looks quite good. And the book is cheap, so pay attention here.

Benne distinguishes two positions on the relationship between religion and politics—separationism and fusionism—and argues Christians ought to reject both. As for the first, there are at least two varieties, one secular and one religious.

Seems like simple clear distinctions that you can add your own nuance to, or not, as you choose.
