Volume 6 of the International Yearbook for Tillich Research takes up the debate on the historical Jesus and explores whether the Christology of Paul Tillich can offer further aspects for the concept of a modern contemporary Christology. The authors of the volume not only trace the relationship between historical Jesus research and dogmatic Christology but also reconstruct the development of Paul Tillich's Christology in the context of his works. While on the one hand his Christology is characterized by a skeptical attitude towards the historical Jesus so typical of the Christology of the 20th century, it is true that on the other hand Tillich's historical philosophical interpretation of Christology reflects the methodological problems confronting present-day Jesus research.
