In this fresh, prodigiously researched approach, the author uses relatively newly found sources to delineate the development of these historical progressions. First, Heather acknowledges Christianity’s failures in the course of its expansions. Second, he explores the diversity of Christian thought and practice through these years. 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.
Heather draws on careful scholarship to give due to the nuances of Christianity’s spread, and constructs a narrative that’s packed with specifics yet readable.
