What does Pentecostalism, the fastest-growing Christian expression worldwide, have to do with Anabaptism, whose Mennonite adherents have sometimes been called "the quiet in the land?" In this groundbreaking study, Joseph C. L. Sawatzky explores a mission history of North American Mennonites working with African Initiated and Pentecostal-type churches in southern Africa, illuminating points of divergence and convergence between Anabaptist and Pentecostal streams. Placing testimonies of African and North American participants in this history within a broader biblical and theological framework, this study proposes bases for an emerging Anabaptist-Pentecostal vision, with implications for the church, its leadership, and its witness in the world. This lively, interdisciplinary study will interest students of mission, interculturality, and the Christian faith itself.
