ABSTRACT
As a result of Jüngel's focus on the cross as the source of all revelation and thus all theology, this chapter will explore the account of existence that results from Martin Luther's theology of the cross, as well as Luther's own navigation of philosophy's use for theology. It will explore key texts not only for the theology of the cross, such as The Heidelberg Disputation, but also note Luther's analysis of human life as found in the Bondage of the Will. Other doctrines, such as Luther's christology and account of justification and their impact on Jüngel's thought, will be noted. The chapter will focus on interpretations of Luther as an ‘existentialist’, and note how that stress informs and appears in Jüngel's own interpretation of Luther. The use of the theology of the cross in Luther will set the scene for how it comes about again in the work of Hegel and Heidegger, and how it is transformed in them as a moment of thought.
