Amy Plantinga Pauw's ‘Supreme Harmony of All’ is the first book-length treatment of Jonathan Edwards's trinitarian theology. She argues that his trinitarian thought embodies the emphases and polarities of the Western psychological model and the Eastern social model of the trinity. Throughout the book she details his doctrines of the immanent and the economic trinity in the contrasting categories of the psychological and the social models of the trinity. She recommends his ‘cobbled’ approach as the only effective way to construct a contemporary trinitarian theology. In contrast, I argue that Edwards consistently used the Augustinian mutual love model. Furthermore, he developed social themes within the mutual love model. His usefulness for contemporary trinitarianism is not to suggest an eclectic method of appropriating conflicting conceptualities, but to challenge the common assumption that Western Augustinian trinitarianism is inherently monistic and must be transcended by recourse to the Eastern trinitarian tradition.
