‘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.’
