Christendom doesn’t feature protagonists, stories, rising and falling action, or shifting points of view. It’s a series of set pieces in which the animating presence is the historian ... The result is an extraordinary synthesis — and one that is, for the most part, extraordinarily hard going ... For most of its reading, the strongest impression the book leaves is of how remote the history of those times and places feels when the notion of Christianity’s exceptionalism is left out ...

In this fresh, prodigiously researched approach, the author uses relatively newly found sources to delineate the development of these historical progressions.

Finally, he examines the reasons why people made the religious choices that they did ... A worthwhile undertaking for serious students of medieval Europe and/or Christian history.
