O Son of God, who didst ascend in glory, save us who sing to Thee, Alleluia!
"O Christ, You have come down from heaven to earth. Being God, You lifted up Adam's race that had been brought down in the prision of Hades. Through your ascension, You raised it up again to the heights of heaven and established it in your company on the Father's throne, for You are merciful and the Lover of Mankind."
(Troparion of the office of the feast)
