“Klassen’s book is much more than a first-rate study of how two churches in Canada positioned themselves within the ostensibly parallel worlds of biomedicine and spiritual healing. It is, at its core, an insightful meditation on the relationship between liberal Protestantism and the project of modernity. A must read not only for students of Christianity, but all those interested in the legacies of secularism and enchantment." —Matthew Engelke, London School of Economics
