I already have (but have not read) three of them. Right now I'm zooming through the one on Baptist Theology. It is outstanding.
As the author acknowledges from the outset, there is not a singular thing as baptist theology, at least not in the same way as we can speak of "reformed theology" or "Lutheran theology" and so forth. At the same time, he does an excellent job of outlining and pulling together the key components of the ethos of baptist belief and practice. It also gives a very good summary of the history of the movement.
It's a very nice read indeed.
