From the award-winning author of The Missionary Movement in Christian History (one of Christianity Today's 100 most influential books of the 20th century) comes this book providing readers remarkable new insights into the ways Christianity has interacted with cultures both historically and today. Fresh understandings of Pentecostalism, African traditional religion, and the ironic ways in which Western missionaries affected change--for both good and ill--in ways they never dreamed of insure that readers will never again think the same way about the history of World Christianity.
