Kathryn Tanner maintains that political theologies based on the Trinity are not only unsound, but potentially dangerous. Her primary concern is that the Trinity, by definition, cannot serve as a “model” for human socio-political organization. Miroslav Volf, while sharing Tanner’s sense that Trinitarian political theologies are fraught, nevertheless, maintains that the Trinity can serve as a “vision” for human socio-political relations, albeit not as a “program”. This article brings Tanner and Volf into conversation with Eastern Orthodox philosopher-theologian Christos Yannaras, whose Trinitarian political theology regards the Trinity as the “prototype” or “archetype” of a mode of existence in which humans can participate by transcending their natures, with the aim of realizing truth. This article argues that Yannaras offers a novel way of conceptualizing Trinitarian political theology which escapes Tanner and Volf’s criticisms, on the one hand, and offers Social Trinitarianism a fresh and fertile perspective that could advance its discourse.
