Abstract
Morality and immorality is a complex issue in Martin Luther's thought and the complexity increases the more he unfolds the topic. In the course of his controversy with Erasmus, he meets a well founded criticism of his own moralization. In the first three sections of this article I discuss their respective positions and the consequences of a moral vs. an immoral interpretation of Scripture. In the last three sections I proceed to inquire whether immorality or rather a-morality may play a more basic and principal role for the interpretation of scriptures in general. The distinction between Scripture as a particular text corpus and the scripturality of the scriptures thereby becomes critical. I suggest that the latter plays a crucial role in Luther's radical criticism and destruction of the moral subsumption of theology, with consequences for a current reassessment of the sola scriptura
