§668

"Christ died and lived again, that he might be Lord both of the dead and of the living." Christ's Ascension into heaven signifies his participation, in his humanity, in God's power and authority. Jesus Christ is Lord: he possesses all power in heaven and on earth. He is "far above all rule and authority and power and dominion", for the Father "has put all things under his feet." Christ is Lord of the cosmos and of history. In him human history and indeed all creation are "set forth" and transcendently fulfilled.
