What I didn't make clear just then is that I loved Verduin's book! On of those works I havn't stopped talking about since I read it, and I'm still working through and chewing over the implications for me personally.
As a friend said, "history with teeth". Very compelling, and enough to push anyone in a pacifist direction. For all thinking Christians with an interest in history and patience to get through some dated (but fairly elegant) prose, this is a must-read.
Shame it's so expensive. But if you see one in a second-hand bookshop snap it up.
