From 1964 to 1983, John Howard Yoder taught a course on theology of mission at Associated Mennonite Biblical Seminaries. The course was recorded in 1973 and 1976, but the tapes were put into storage and subsequently forgotten. Thanks to Wilbert Shenk and the director of the AMBS library, the tapes of Yoder's course were discovered thirty years later in 2006. Painstakingly transcribed and edited by Gayle Gerber Koontz and Andy Alexis-Baker, this book is the exciting result.
