John Howard Yoder went to Europe after the Second World War as a young volunteer. Yoder worked as an aide in a children's home in Elsace, France and completed his doctorate under Karl Barth in Basel, Switzerland. Because of his incomparably clear and sharp thinking he quickly became one of the most sought after speakers on pacifism at seminars as he worked towards an Anabaptist renewal of the church. In this context Yoder succeeded in reopening the theological debate on Christians and political responsibility with the larger church to which persecution had put an end 400 years earlier. Biblical scholar Timothy J. Geddert translated two of these lectures, originally given in Germany, as a resource to understand Yoder's invitation to begin an exploratory journey that leads to Jesus Christ's peace church.
