Matt Baglio is to be commended on steering a steady course through some fairly perilous waters and managing to give a clear-headed and relatively dispassionate account of the Vatican-sponsored, university-based training in exorcism undertaken by a contemporary American priest.
At the risk of simply rehashing the blurb from the book's cover, this really is a fascinating insight into a world that most of us are probably completely unaware of, other than through Hollywood. Coming from a position of confirmed aetheism, it's quite a shock to learn just how many people, especially in Italy, are seemingly afflicted by "demonic possession". Without wishing to question the sincerely-held beliefs of the "victims", it is hard not to wonder at how these people have been failed by the respective national medical and social welfare systems.
Father Gary Thomas has performed a valuable service in co-operating with the author and both men are to be commended on a work which will be of significant interest and value to believer and non-believer alike.
If I had one critiscism it would be that Father Gary's post-Rome experience of exorcism in the field, back in his native USA, could have been treated more extensively.
