An opus of Luther´s with an innovative approach: Humor and melancholy as the basic attitudes in life – corresponding to the faith-based distance to one´s self and to the refutation. Söderblom is above all known as a historian of religion and an ecumenical man of the Church. But he also did much for theology, especially for the interpretation of Luther. This volume presents one of his three most important monographs on Luther: "Humor and Melancholy and other Luther Studies." This volume is known for its innovative approach of not concentrating on Luther´s teachings but on his personal piety. Humor and melancholy are understood as basic attitudes in life. They correspond to the faith-based distance to one´s self and to the refutation.
