Abstract
In a recent article Steven Cowan defended the claim that female subordination and male authority are merely functional differences. Drawing insights from Natural Law, I argue that complementarianism typically speaks of these as proper functions of male and female designs, thus making men and women metaphysically unequal in being. Furthermore, I maintain that the function "serving as a means to an end" is less valuable than the function "having the authority to direct the end." Hence, Cowan fails to defeat the objection that the claim that women are equal to men in being, but subordinate in role is incoherent.
