The book aims at showing the most important topics and paradigms in modern Trinitarian theology. It is supposed to be a comprehensive guide to the many traces of development of Trinitarian faith. As such it is thought to systematize the variety of contemporary approaches to the field of Trinitarian theology in the present philosophical-cultural context. The main goal of the publication is not only a description of what happened to Trinitarian theology in the modern age. It is rather to indicate the typically modern specificity of the Trinitarian debate and - first of all - to encourage development in the main areas and issues of this subject.
