CCC 2812 Finally, in Jesus the name of the Holy God is revealed and given to us, in the flesh, as Savior, revealed by what he is, by his word, and by his sacrifice.1 This is the heart of his priestly prayer: “Holy Father. .. for their sake I consecrate myself, that they also may be consecrated in truth.”2 Because he “sanctifies” his own name, Jesus reveals to us the name of the Father.3 At the end of Christ’s Passover, the Father gives him the name that is above all names: “Jesus Christ is Lord, to the glory of God the Father.”4
