The renaissance of trinitarian theology is one of the most important ecumenical theological movements of our time. In the context of religious and ideological pluralism, the question of the identity of the triune God becomes the key to understanding the structure of the Christian faith and the life of the Church. Christoph Schwöbel argues that the doctrine of the Trinity serves as a framework theory and integral part of the Christian faith and its explication in dogmatics. Based on this thesis, he addresses fundamental issues of dogmatics in the individual studies of this volume, a significant portion of which is published in German for the first time. "This book impresses with its clarity, comprehensibility, and ability to engage in dialogue." Johannes Schilling in Luther, Vol. 74, Issue 2/2003, p. 102.
