Jesus of Nazareth is said to be the sacrament of the saving grace of God and of man’s response to God in that grace. In himself Jesus is the encounter between God and mankind, the Immediator of man and God, the Word of God made world and history, man in his concrete dimensions and the total nexus of his relationships taken up into God. According to the apostolic preaching, in him alone, in his ‘name’ alone, is there the means of passing from a lethal situation into the possibility of survival. If men are going to pass from the world that is doomed to death, that can only be by entering into him, into his name, by in some way becoming him, by living out the biography of the one who, alone, no longer belongs to the dead past. Living it out, amongst other ways, sacramentally. Sacramentally we put on Christ, we are conformed to Christ, we are made one body, one spirit, with him.
