Christoph Friedrich Blumhardt (1842–1919), with his unconventional ideas about the kingdom of God, profoundly affected a whole generation of European seekers. Pastor, politician, and author, he influenced Dietrich Bonhoeffer, Emil Brunner, Oscar Cullman, and Karl Barth, among other luminaries. Yet his vision and witness are still waiting to be discovered by most Americans, few of whom have had access to his works. He carried forward the work of his father, Johann Christoph Blumhardt (1805–1880), who is regarded by many as the key figure of German pietism. Christian T. Collins Winn (PhD, Drew University) is Associate Professor of Theology at the Global Center for Advanced Studies, College Dublin, and a licensed minister in the American Baptist Churches (USA). He is author of “Jesus is Victor!” The Significance of the Blumhardts for the Theology of Karl Barth. Charles E. Moore is co-editor, with Christian T. Collins Winn, of The Blumhardt Source Series. He has also edited several acclaimed popular collections of Blumhardt writings, including Action in Waiting, Everyone Belongs to God, and The God Who Heals. Other books he has compiled and edited include Called to Community: The Life Jesus Wants for His People, Bearing Witness: Stories of Martyrdom and Costly Discipleship, Provocations: Spiritual Writings of Kierkegaard, and Leo Tolstoy: Spiritual Writings.
