the Bishop primarily as the president of the Divine Liturgy and the Eucharistic community. Theological ontology Zizioulas worked on the theology of the person, appealing to the work of St Irenaeus and St Maximus the Confessor. The primary focus of his work was to develop his own ontology of personhood derived from an extensive investigation of Greek philosophy, patristic era writings and modern rationalist philosophy. He argues that full humanity is achieved only as person so that they may participate (koinonia) in the Trinitarian life of God. However, an essential component of the ontology of personhood is the freedom to self-affirm the participation in relationship. He continues that man initially exists as a biological hypostasis, constrained as to the types of relationships one can have (biological) and to the eventual end of this type of being - death. He makes use of existentialist philosophers and novelists, notably the French absurdist writer Albert Camus, to show that the only type of ontological freedom in the biological hypostasis is the choice to commit suicide. He claims that Baptism constitutes an ontological change in the human, making them an ecclesial hypostasis, or a person. This rebirth 'from above' gives new ontological freedom as it is not constrained by the limits of biological existence. Such ecclesial being is eschatological, meaning it is a paradoxical 'now,' but 'not yet.' The completion of this rebirth from above is the day of resurrection when the body will no longer be subject to death.
