I found this book very interesting, but I think it would be more helpful for recipients of the sacrament of reconciliation if it were not written so academically.
My two quibbles: I think it came down a little too heavy on stereotypes about the way things "used" to be around confession. And I think that, while structures in society that lead to corporate sin also need to be named and repented of, I'm not convinced that the confessional is the place to do it.
Those two things aside, there was a lot of food for thought here. I especially liked the continued emphasis on getting away from the "laundry list" of sins, and using the sacramental grace of confession to get at the heart of *why* we keep committing the same sins--what vice is at the root of our actions, and how we can be purified and healed of it.
