Jesus means in Hebrew: "God saves." At the annunciation, the angel Gabriel gave him the name Jesus as his proper name, which expresses both his identity and his mission.18 Since God alone can forgive sins, it is God who, in Jesus his eternal Son made man, "will save his people from their sins".19 in Jesus, God recapitulates all of his history of salvation on behalf of men.
The name of the Savior God was invoked only once in the year by the high priest in atonement for the sins of Israel, after he had sprinkled the mercy seat in the Holy of Holies with the sacrificial blood. The mercy seat was the place of God's presence.25 When St. paul speaks of Jesus whom "God put forward as an expiation by his blood", he means that in Christ's humanity "God was in Christ reconciling the world to himself.
Jesus' Resurrection glorifies the name of the Savior God, for from that time on it is the name of Jesus that fully manifests the supreme power of the "name which is above every name".27 The evil spirits fear his name; in his name his disciples perform miracles, for the Father grants all they ask in this name.
The name of Jesus is at the heart of Christian prayer. All liturgical prayers conclude with the words "through our Lord Jesus Christ". The Hail Mary reaches its high point in the words "blessed is the fruit of thy womb, Jesus." The Eastern prayer of the heart, the Jesus prayer, says: "Lord Jesus Christ, Son of God, have mercy on me, a sinner." Many Christians, such as St. Joan of Arc, have died with the one word "Jesus" on their lips.
