For Western readers, MacCulloch is perhaps most interesting when he retrieves the experience of the Eastern churches, showing no particular bias toward any of the religion's variants. Yes, Christians often slaughtered their adversaries both within and without the faith (and were slaughtered themselves when they didn't have the upper hand).That's all there, but it is not MacCulloch's focus. Rather he recounts the numerous odd byways of faith with unfailing interest in and often delight at their sheer multiplicity.
I'll skip trying to say anything more in summary, but I did want to share one passage that I frequently recalled during my recent travel in Nepal.
Expect other tidbits of MacCulloch to appear here as life jogs my memory of this remarkable historical tour de force.
