Divine Commands, Natural Law, and the Authority of God

Does morality depend ultimately on the rationally compelling force of natural law, or on God’s authoritative commands? These are not exclusive alternatives, of course, but they represent two widely influential ways of understanding the moral order seen in relation to divine wisdom, goodness, and power. Each alternative underscores some elements of theistic belief while deemphasizing others. Theories of the natural law emphasize the intrinsic goodness of the natural order to the potential detriment of divine freedom, whereas divine command theories underscore God’s sovereign freedom but at the risk of implying that the moral order is arbitrary and God’s will is, at best, opaque. It might seem that these alternatives are not only distinct but fundamentally at odds, but we may well ask whether this is necessarily the case. Natural law and divine command theories of ethics have persisted because each seems to preserve some key elements of theistic belief, and for that reason, theists have a stake in holding on to each perspective if possible.
