Luther was a point of reference in all three of the confessional cultures during the confessional age, though this was not something he had intended. His theological “self-fashioning” was not meant to secure, canonize, or stabilize his own works or his biography. Rather, he believed, and was convinced, that the hidden God rules in a strange way. He hides himself in the course of the world and realizes what we would have liked to realizes. Apart from this theological viewpoint, historiographic differentiation is needed: Luther had different impacts on each of the three confessions. Furthermore, one also has to differentiate between a deep impact and the unintended effects of Luther’s thinking. Luther was an extremely polarizing figure. From the beginning, he underwent a heroization and a diabolization by his contemporaries. Apart from this black-and-white reception of his person, it was, and still is, extremely difficult to analyze Luther, his work and medial effects. Historians have always been fixated on Luther: he was the one and only founder of Protestantism. His biography became a stereotype of writing and was an important element of Protestant (or anti-Protestant) identity politics. For some Protestants, his biography became identical with the history of salvation (Heilsgeschichte). For his enemies, his biography was identical with the history of the devil.
In all historical fields, one has to differentiate between the different groups and people who protected or attacked Luther or shared his ideas. The history of Luther can only be written as a shared history with conflict and concordances: the so-called Anabaptists, for example, shared Luther’s antihierarchical ideal of Christian community, although on the other hand “they” were strongly opposed toward his theology and person. Luther or example, had conflicts with the humanists and with Erasmus especially; he argued about the Lord’s Supper with Zwingli, he criticized the Fuggers because of their financial transactions in an early capitalist society; and, last but not least, he was in conflict with the Roman Church. The legitimization of different pictures of Luther always depends upon the perspectives of the posterity: either Luther was intolerant against spiritualists, Anabaptists, or peasants who were willing to resort to violence; or he was defended by humanists like Sebastian Castellio for defending religious tolerance. During his lifetime Luther was an extremely polarizing figure. Hundreds of pro-Lutheran and polemical anti-Lutheran leaflets or texts were published. The many literary forms of parody, satire, caricature, the grotesque, and the absurd were cultivated during the confessional age. Luther’s biography was often used by Lutheran theologians as an instrument of heroization and identity politics in public discourse.
Historically, one can differentiate between the time before and after Luther. The political and religious unity of the Holy Roman Empire was strongly disturbed, if not broken, through the Reformation. The end of the Universalist dreams of universal powers like theology and politics (pope and emperor) were some of the central preconditions for political, cultural, and theological differentiation of Europe. Religious differentiation was one of the unintended effects of theology and the interpretation of the scripture. Decades after Luther’s death, the Holy Roman Empire slowly and surprisingly turned into a poly-, multi- and interconfessional society.
