Psalms 47:5

He ascended with a shout of jubilation, since he sought heaven as the disciples rejoiced in the glory of his being lifted up. He ascended with the sound of the trumpet, since he went up to the throne of his heavenly kingdom as the angels heralded his return to judge the living and the dead.

For on account of this very lifting up of our flesh, blessed Job figuratively calls the Lord a bird. For since he saw that Judea would not understand the mystery of His Ascension, he pronounced sentence on their unbelief, saying, "The bird knew not the path." For the Lord was rightly called a bird, because He raised His fleshly body to the heavens. Whoever did not believe that He ascended to heaven did not know the path of this bird. Concerning this solemnity it is said through the Psalmist, "Your magnificence is exalted above the heavens." Concerning this again he says, "God ascended with jubilation, and the Lord with the sound of the trumpet." Concerning this again he says, "Ascending on high, He led captivity captive, He gave gifts to men." For ascending on high, He led captivity captive, because He absorbed our corruption by the power of His incorruption. And He gave gifts to men, because, sending the Spirit from above, to one He granted the word of wisdom, to another the word of knowledge, to another the grace of powers, to another the grace of healings, to another kinds of tongues, to another the interpretation of speeches.

"God is gone up with jubilation." Even He our God, the Lord Christ, is gone up with jubilation; "the Lord with the sound of a trumpet." "Is gone up:" whither, save where we know? Whither the Jews followed Him not, even with their eyes. For exalted on the Cross they mocked Him, ascending into Heaven they did not see Him. "God hath gone up with jubilation." What is jubilation, but admiration of joy which cannot be expressed in words? As the disciples in joy admired, seeing Him go into Heaven, whom they had mourned dead; truly for the joy, words sufficed not: remained to jubilate what none could express. There was also the voice of the trumpet, the voice of Angels. For it is said, "Lift up thy voice like a trumpet." Angels preached the ascension of the Lord: they saw the Disciples, their Lord ascending, tarrying, admiring, confounded, nothing speaking, but in heart jubilant: and now was the sound of the trumpet in the clear voice of the Angels, "Ye men of Galilee, why stand ye gazing up into Heaven? this is Jesus." As if they knew not that it was the same Jesus. Had they not just before seen Him before them? Had they not heard Him speaking with them? Nay, they not only saw the figure of Him present, but handled also His limbs. Of themselves then knew they not, that it was the same Jesus? But they being by very admiration, from joy of jubilation, as it were transported in mind, the Angels said, "that same is Jesus." As though they said, If ye believe Him, this is that same Jesus, whom crucified, your feet stumbled, whom dead and buried, ye thought your hope lost. Lo, this is the same Jesus. He hath gone up before you, "He shall so come in like manner as ye have seen Him go into Heaven." His Body is removed indeed from your eyes, but God is not separated from your hearts: see Him going up, believe on Him absent, hope for Him coming; but yet through His secret Mercy, feel Him present. For He who ascended into Heaven that He might be removed from your eyes, promised unto you, saying, "Lo, I am with you always, even unto the end of the world." Justly then the Apostle so addressed us, "The Lord is at hand; be careful for nothing." Christ sitteth above the Heavens; the Heavens are far off, He who there sitteth is near...
