My thoughts on this book are several:
I. First, I want to stress that this is a solid theological text, not a polemical work. I think some were expecting this book to be a collection of traditionalist maledictions on the canonizations of John Paul II and Paul VI; when I said I had an essay published in this book, Dave Armstrong immediately expressed dismay and embarrassment that I would participate in the project. I think he assumed it was just going to be a hackneyed trad critique of the modern papal saints. It's anything but. I was consistently struck by the scholarly tone of the book and how its authors are determined to get to the principles that underlay the question. This is a book for people serious about understanding the theological questions behind canonization. Some of the essays are dense and of a very technical nature. Expect an enlightening read, but not necessarily an easy one.
II. The book is not an anti-infallibilist apologetic. I would say the majority of the essays are anti-infallibilist, but certainly not all of them. Both sides are represented fairly, and the arguments are much weightier than "I don't like Paul VI therefore he's not a saint" (anti-infallibilist caricature), or "The Church has spoken, shut up" (infallibilist caricature). On the contrary, the format of this book as a running dialogue between proponents of various positions along the spectrum sheds light on a host of issues of which I'd never been aware. I can't say the anti-infallibilist arguments were wholly convincing, but whether you are pro or anti-infallibilist, this book should make it clear that the questions run a lot deeper than you'd probably assumed.
In conclusion, I highly recommend Are Canonizations Infallible? and I commend the folks at Arouca Press for doing such good work on this and their other publications. I also want to thank Arouca and Dr. Kwasniewski for including me in such a scholarly and important work, something my credentials and scholarship hardly merit. But still, don't let my inclusion in the book be an argument against it; get yourself a copy and educate yourself about this important issue.
