Summary

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.
