This paper argues that the Dominican, Robert Holcot's, Trinitarian theology is methodologically consistent with what one finds in the Franciscan theologian, William of Ockham's, Summa logicae. Both theologians, it is argued, develop a form of Trinitarian minimalism that rejects many of the developments in thirteenth-century Trinitarian theology. Further, it is argued that the traditional two-model approach to medieval Trinitarian theology, as found in Théodore de Regnon, Michael Schmaus, and Russell Friedman must be re-evaluated in light of current research.
