John Zizioulas
1931–2023 · Eucharistic ecclesiology; trinitarian personalism
Metropolitan of Pergamon under the Ecumenical Patriarchate and Orthodox co-chairman of the Joint International Commission for Theological Dialogue with the Catholic Church, which produced the Ravenna Document (2007) on primacy and conciliarity.
A student of Florovsky at Harvard, Zizioulas argued in Being as Communion (1985) that the Cappadocian Fathers made person, not substance, the ultimate category of being: the Father as the free cause of the Trinity means that God is communion, and that to be a person is to exist in ecstatic relation to others, not as an individual. The Church is constituted by the Eucharist, each local Church under its bishop being the whole Church, and truth is a matter of communion and of the age to come rather than of correspondence alone. Communion and Otherness (2006) extended this into an ontology of otherness and freedom, and his later work made the human being the “priest of creation” whose task is to refer the world to God. He defended a universal primacy exercised within synodality, and criticized Lossky's reliance on the essence-energies distinction and on apophaticism.
Why he matters: No Orthodox theologian has been more fully received by Catholics: Ratzinger, Kasper and the Communio school took up his trinitarian personalism and eucharistic ecclesiology, Paul McPartlan set him beside de Lubac, and the Ravenna Document is as much his as anyone's. His account of the person as constituted by relation is the strongest modern form of an insight that Catholic personalism had reached by other roads.
Where to be careful
He holds the primacy of Peter's successor to be real but synodal, short of the immediate universal jurisdiction defined in Pastor Aeternus; his reading of the Cappadocians has been faulted by patristic scholars such as Turcescu, and his ontology of person makes nature almost an afterthought, which sits uneasily with Chalcedon's two natures and with the Church's language of natural law. His eucharistic ecclesiology is the common ground on which Lumen Gentium 26 and Orthodox theology already meet.
