The renaissance of virtue ethics in Christian moral discourse has led a handful of Reformed theologians to consider whether or not the Reformed tradition is compatible with classical and medieval concepts of virtue. Barthians, in particular, express doubt regarding the prospect of such a retrieval, arguing that classical notions of virtue compromise the Reformed hallmark of divine sovereignty and Luther's dictum simul justus et peccator. This essay counters that the Reformed tradition is broad enough to find more productive ways to engage virtue ethics. In particular, the Westminster Standards provide both the formal space for a significant theological exploration of human agency and the material content for the development of something like a classical virtue ethic. Barthian concerns regarding divine sovereignty and moral progress are satisfied by a demonstration that Westminster's attention to human agency is always within the context of a greater emphasis on divine agency.
