The authors wrote a very insightful book on the theology of St. Thomas Aquinas. It is meant to be an introduction to his work but do not be fooled. It is not light reading so I would advise the reader to take their time and read it in "chunks." It appears to be written in a prayerful spirit and their insights are so beautiful that it may cause the reader to pause and pray themselves. Hopefully, it will lead the reader to study St. Thomas further and directly. One would do well to also read the small book by Jean-Pierre Torrel,O.P. entitled "Aquinas's Summa: Background, Structure, and Reception."However, in my opinion, I believe the authors are not merely presenting an introduction to the theology of St. Thomas Aquinas. They are also sharing their interpretation and development of some of his thought. This is not a bad thing; in fact, it is a good thing but it is difficult to discern which is St. Thomas and which is the authors' development.
