This book on Europe is an odd one. It never really answers the question of the title (though it talks like it will in the first chapter), instead exploring the mixing of Christianity with Greek/Roman, Celtic, and Germanic cultures as the faith spread throughout the contintent. That is really interesting and the most engaging part of the book, though I think some of the history he is relying on is a little outdated. The last chapter tries to bring ideas from the past to the present day, but it is a convoluted mess and seems to be advocating some sort of syncretism in our image based culture. It hints where it needs to be more direct. A book with some ideas, but which feels like a good part of what should be its argument has been skipped over.
