Combining his deep knowledge of Luther with a passion to speak the promising word of the gospel with clarity and integrity in our age, Oswald Bayer has emerged as a leading Lutheran theologian. The chapters in this Festschrift demonstrate the wide scope of Bayer’s interest: Martin Luther, Johann Georg Hamann, the doctrine of justification, ethics, hermeneutics, theological method, sacraments, and the theology of lament. These essays, written by scholars from North America and Australia who have been influenced by Bayer’s pioneering work, demonstrate the resources that his work has for not only Reformation studies and systematic theology but also for preaching, liturgical theology, pastoral care, and apologetics. For those who are not yet acquainted with the contributions of this Tubingen theologian, Promising Faith for a Ruptured Age: An English-Speaking Appreciation of Oswald Bayer will serve as a guide to and commentary on Bayer’s multifaceted approach to theology. Those familiar with Bayer’s work as a systematic theologian and Luther scholar will discover new applications of fundamental themes for in interdisciplinary research, ecumenical conversation, and church life.
