A passionate opponent of Nazism, Karl Barth was required to serve in the Swiss army. At the age of 54, he helped guard the Swiss border at Basel from German intruders. Some would suggest this is all we need to know in order to understand Barth’s views on Christianity and war—but as this volume demonstrates, John Howard Yoder begged to differ. In “Karl Barth and the Problem of War” Yoder articulates the views of his former teacher on war, these views comprising a position he refers to as “chastened non-pacifism.” Through a rigorous examination of Barth’s ethical method, Yoder seeks to show how the logic of Barth’s basic theological commitments makes him even closer to pacifism than is often noticed. Five additional essays, three never before published, offer further reflections on Barth’s position, as well as offering some of Yoder’s fruitful use of Barth’s theology for social ethics.
