"William Klempa's translation of Karl Barth's Safenwil sermons at the outbreak of World War I, accompanied by a very fine introduction that sets the historical and theological context, represents the culmination of a careful, critically appreciative, and lifelong engagement by Klempa with Barth's theology. All readers of Barth are indebted to Klempa, a seasoned interpreter of Barth, for making a new English translation of this important part of the Barth corpus available."
—JOHN A. VISSERS, Professor of Historical Theology, Knox College, University of Toronto

"In his illuminating introduction to his fine translation of Barth's World War I sermons, William Klempa demonstrates in A Unique Time of God how these sermons are the true beginning of Barth's later theology: through them a revolutionary theology was born out of the necessity and struggle of proclaiming the Christian message during the first few months of the Great War. In these sermons, the pastoral and theological strengths of the young Barth are already present. Also evident are the liberal emphases of nineteenth-century theology and the beginning of Barth's negation of them. Klempa's work sets in high relief a major milestone in twentieth-century theology."
