Communing with the Triune God: Petrus van Mastricht, Ecumenism, and the Nicene Roots of Communion with God

The recent development of receptive ecumenism has renewed the ecumenical movement and provided a way forward in which ecclesial communities receive and give gifts to one another. This essay attempts to offer an account of receptive ecumenism in a distinctively Reformed key, centered around Nicene notions of communion with God. In light of how previous grammatical approaches to ecumenism have terminated in the mere elucidation of difference, this essay builds upon Petrus van Mastricht’s account of communion with God as a resource for understanding and conceiving of ecumenism as premised on mutual communication and sharing of meanings.
