Were Luther to have lived another two decades, he might have been surprised even so early on to be informed that he positively influenced the rise of natural science. One can readily cite many Luther quotes that would cast him as anti-science; decontextualized quoting readily constructs such caricatures. But the truth of the matter is quite otherwise. Consideration of Luther and Luther’s protégés and their philosophical-historical contexts reveals their positive regard for science. This is explicit in Luther’s immediate heirs like Melanchthon and Andreas Osiander. Though they differed in their opinions about the work of Copernicus, both respected him and the discipline he practiced. Luther’s influence carried beyond his immediate disciples through Johannes Kepler into the 17th century. The Irish-Anglican chemist and theologian Robert Boyle, for example, was significantly influenced by the Reformation principle of God’s sovereignty. In turn, Boyle strongly influenced Isaac Newton. But Lutheran support for the natural sciences had one major qualification. When “freed science” appeared to speculate more on God’s action than describe the visible character of natural phenomena, Luther saw overreaching ambition. Such are the outlines of a historical approach of Luther’s influence on the beginning of the scientific revolution. Other Lutheran theological themes contributed to natural science’s robustness. In addition to a focus on God’s sovereignty—and so the doctrine of justification by grace through faith—these themes include (1) the nature of biblical authority, (2) the “realistic” epistemology of the theology of the cross, and (3) sacramentology.

Luther’s understanding of God saturates his oeuvre, and in turn, this understanding is saturated by his doctrine of the justification of the sinner. God is the sovereign source and origin of all that is, and Luther develops his understanding of God in a manner that tries to safeguard this position in such a way that the personal relationship to God becomes the focus point for all he says. The doctrine of God as creator and as savior is modeled in a parallel way in Luther, as he sees God as the source of everything positively in both contexts. God is the sole giver of the gifts that human life requires. As creator, God is omnipresent, omniscient, and sovereign. Nothing can determine God. God is accordingly also the only instance in reality that has free will. Everything else is dependent on God, God’s foreknowledge, and God’s predestination. It is possible to see Luther’s position as an attempt to offer the human being a reliable and trustworthy notion of God, someone he or she can cling to in times of despair and desolation. The only God who deserves to be God, who is trustworthy with regard to being able to provide a safe and reliable basis for human life, is the God who justifies the sinner because of God’s own righteousness. In contrast, a human who puts her trust in herself and her own works or merits makes herself a god and will not be able to stand justified coram deo in the last judgment. Luther develops the idea about God’s hiddenness in different ways, most notably in his ideas about the hidden God in De servo arbitrio. But also in his notion of the theology of the Cross in the Heidelberg Disputation, and in other places where he writes about the masks of God, behind which God hides in order to do God’s work, we can see related or similar ideas. Thus, Luther develops an ambiguous element in his understanding of God.

The topic of Luther in Marxism is vast and too diffuse to be useful to define issues and orient future research. However, the more limited topic of Luther in Marx is definite, manageable, and useful. If the framing of the relation between Luther and Müntzer first created by Müntzer and then adopted and popularized by Engels can be bracketed, and if the comparison of Luther and Marx is carefully controlled by Marx’s encounter with Luther texts, the result is a tacit but surprising claim by Marx to have found in Luther a predecessor in the analysis of capitalism. This surprise, however, entitles Luther to be heard afresh in his own voice in making his theological-ethical critique of mercantilism and monopoly finance in the 16th century. This new listening to Luther yields a concurrence between Luther and Marx regarding Marx’s claim that, in distinction from historical Christianity, the Marxist revolution brings an earthly, not otherworldly salvation; Luther, however, states just this difference differently, in terms of the Augustinian ordo caritatis. The double love commandment drives his own analysis of the proper Christian use of temporal goods. Beyond the exposé by Luther’s Augustinian theology of the false loves moving the civitas terrena, however, we discover the descent of critical social thinking to both Luther and Marx from the apocalyptic tradition of Second Temple Judaism. Recognizing this family resemblance makes visible the messianic divergence between the two. With this divergence clarified, new questions for Luther research arise.
