Catalog of Testimonies

This 1580 theological compilation represents one of the most ambitious attempts in Reformation history to demonstrate that Lutheran Christology did not deviate from ancient Christian orthodoxy. Compiled by Jakob Andreae as an appendix to the Book of Concord, it systematically pairs passages of Scripture with citations from the Church Fathers, Origen, Augustine, Athanasius, and others, to argue that the Formula of Concord's formulations about Christ's person and nature were not novel innovations but faithful continuations of centuries-old theological consensus. For readers interested in how Christianity navigated its own internal debates about the nature of divinity and humanity in Christ, this catalog offers an extraordinary window into the Reformation's self-understanding as a restorer rather than inventor of doctrine. The text reveals a theological world in which every word mattered, every citation carried weight, and the stakes of Christological definition were nothing less than the integrity of Christian faith itself. It will appeal to scholars of Reformation history, theologians, and anyone curious about how religious communities construct and defend their claims to continuity with the past.
