As an introduction to theological reflection, it certainly does its job. If the goal in reading is to understand how to do theological reflection, how to broaden one's horizons, or how to understand how others may reflect theologically, one could certainly do worse than starting here. The various forms of theological reflection are both explained and exhibited.
However, I am a little disappointed in two key ways. First, when showing examples of the method's use throughout history, there is a progression from "old," to "modern," to then "method realized." Apparently, the most contemporary versions of each method are the culmination and realization of the method. That's troubling. Even if we are to say that those who reflect theologically with a particular method are doing so more knowingly than those in the past have, we are still suggesting that prior to our present era religious were incapable of fully reflecting theologically and spiritually. It is possible to argue that our theology today is closer to God's truth, at least within each method, but the notion that we can trust ourselves and today's theologians more than anyone else throughout history is a bit silly.
Secondly, there isn't much in the way of invitation. Yes, the process of theological reflection and each method are explained well, but if the point of theological reflection is to do it rather than understand it, then we're out of luck here. A single chapter at the end to invite practical exploration, or a single paragraph at the end of each chapter, would have been enough.
