One of the world's most influential theologians clearly and persuasively outlines a doctrine of the church concerned with Christian unity and the failure of the churches to resolve denominational conflicts. In this long-awaited second volume of Wolfhart Pannenberg's Ethik und Ekklesiologie, divisive issues that have persisted for centuries are put into new and hopeful perspective. Pannenberg considers difficult questions about authority, catholicity, apostolicity and the Lord's Supper. Throughout, he maintains the eschatological awareness that distinguishes all of his theological writing and shows that church unity rests not primarily on unity of doctrine but on common confession of Jesus Christ.
