Dogmatics, as a conceptual account of the Christian faith, is a soteriological interpretation of reality. It analyzes the need for salvation under the premise of the biblically attested reality of salvation. This is the fundamental idea of the renowned Viennese systematician Ulrich H. J. Körtner in his comprehensive textbook presented here, which is divided into five main parts. Using the key concepts of God, world, and humanity, it offers a compact representation of all major themes in Christian dogmatics, their historical problem contexts, and the current discussions. Key statements consolidate the line of thought. The textbook, committed to the Lutheran and Reformed heritage of Reformation theology, particularly takes into account the Leuenberg Concord (1973) and the teaching dialogues of the Community of Protestant Churches in Europe.
