Eucharistic priority in Hilary of Poitiers' trinitarian theology: a critique of contemporary approaches to divine–human communio

Abstract

The notion of koinonia or communio is at the heart of contemporary ecclesiology, and trinitarian theology has become its necessary presupposition. This article argues that the way many contemporary theologians have envisaged this link between divine and human communion is deeply problematic. Hilary of Poitiers was the first theologian of communio, and he offers a bold critique of contemporary discussions. Hilary gives eucharistic priority to trinitarian theology, that is, there is a movement from Eucharist to Trinity in his thinking on the relation between divine and human communion. A retrieval of Hilary's eucharistic priority in trinitarian discourse can provide constructive avenues in trinitarian theology which avoid the anthropocentric tendencies of contemporary social doctrines of the Trinity and reject the misdiagnosed problem of trinitarian ‘relevance’ in current discussions. Such a retrieval recovers trinitarian doctrine as a practised, performed reality, lived out in human communio itself through the eucharistic life of the Church.
