This book presents twenty essays written in honour of the noted theologian and ecumenist Geoffrey Wainwright, Cushman Professor of Christian Theology at Duke University. The editors have assembled a remarkable international roster of contributors and have organized the volume around three major themes in Wainwright's work: worship, liturgy, and mission. Contributors include Nicholas Lossky, Eberhard Jungel, Dietrich Ritschl, and Gunther Gassman.
