‘Christology, in the definitive form which the Fathers gave it, looks towards a single goal of purely existential significance, the goal of giving man the assurance that the quest for the person, not as a “mask” or as a “tragic figure,” but as the authentic person, is not mythical or nostalgic but is a historical reality. Jesus Christ does not justify the title of Savior because He brings the world a beautiful revelation, a sublime teaching about the person, but because He realizes in history the very reality of the person and makes it the basis and “hypostasis” of the person for every man.’
John D. Zizioulas, Being as Communion. Studies in Personhood and the Church. London, DLT, 1985 (2004) 54.
