The cloud reference in Catholicism is not a literal cloud, official teaching is that Jesus ascended in the theological cloud representative of God, the cloud that guided Moses.
Well, no actually.
The
cloud references in the Old Testament, New Testament and in Catholicism are not merely that Jesus ascended in the "theological cloud,” but very clearly that
Jesus is God.
In the Old Testament it is
God and God alone who is above the clouds.
Yahweh is the One who “rides" the clouds because he is above them:
“Sing praises to God and to his name! Sing loud praises to
him who rides the clouds. His name is Yahweh — rejoice in his presence!” Psalm 68:4
“Let all that I am praise Yahweh. O Yahweh my God, how great you are! You are robed with honor and majesty. You are dressed in a robe of light. You stretch out the starry curtain of the heavens; you lay out the rafters of your home in the rain clouds.
You make the clouds your chariot; you ride upon the wings of the wind.” Psalm 104:1-3
“This message came to me concerning Egypt: Look!
Yahweh is advancing against Egypt, riding on a swift cloud. The idols of Egypt tremble. The hearts of the Egyptians melt with fear.” Isaiah 19:1
When the prophets, like Daniel, speak of “coming ON the clouds of heaven,” they are referring to God.
“As my vision continued that night,
I saw someone like the Son of Man coming with the clouds of heaven. He approached the Ancient of Days and was led into his presence. He was given authority, honor, and sovereignty over all the nations of the world, so that people of every race and nation and language worshiped him.
His rule is eternal—it will never end. His kingdom will never be destroyed.” Daniel 7:13-14
“But in the end, the holy people of the Most High will be given the kingdom, and they will rule forever and ever… until the Ancient of Days—the Most High—came and judged in favor of his holy people. Then the time arrived for the holy people to take over the kingdom.… Then the sovereignty, power, and greatness of all the kingdoms under heaven will be given to the holy people of the Most High. His kingdom will last forever, and all rulers will serve and obey him.” Daniel 7:18, 22, 27
“Rejoice, O people of Zion! Shout in triumph, O people of Jerusalem!
Look, your King is coming to you. He is righteous and victorious, yet he is humble, riding on a donkey—riding on a donkey’s colt. I will remove the battle chariots from Israel and the warhorses from Jerusalem. I will destroy all the weapons used in battle, and your king will bring peace to the nations. His realm will stretch from sea to sea and from the Euphrates River to the ends of the earth. Because of the covenant I made with you, sealed with blood, I will free your prisoners from death in a waterless dungeon…
Yahweh will appear above his people; his arrows will fly like lightning! The Sovereign Yahweh will sound the ram’s horn and attack like a whirlwind from the southern desert. Yahweh of hosts will protect his people, and they will defeat their enemies by hurling great stones. They will shout in battle as though drunk with wine. They will be filled with blood like a bowl, drenched with blood like the corners of the altar.** On that day Yahweh their God will rescue his people, just as a shepherd rescues his sheep.** They will sparkle in his land.” Zechariah 9:9-11, 14-16
“And
Yahweh will be King over all the earth. On that day there will be one Yahweh — his name the only one… In the end, the enemies of Jerusalem who survive the plague will go up to Jerusalem each year to worship the King, Yahweh of hosts, and to celebrate the Festival of Shelters. Any nation in the world that refuses to come to Jerusalem to
worship the King, Yahweh of hosts, will have no rain.” Zechariah 14:9, 16-17
These are precisely the words Jesus uses to describe himself and his coming.
“Then the high priest stood up before them and asked Jesus, ‘Are you not going to answer? What is this testimony that these men are bringing against you?’ But Jesus remained silent and gave no answer. Again the high priest asked him, ‘Are you the Christ, the Son of the Blessed One?’ ‘
I Am,’ said Jesus. ‘And
you will see the Son of Man sitting at the right hand of the Mighty One and coming on the clouds of heaven.’ The high priest tore his clothes. ‘Why do we need any more witnesses?’ he asked. ‘
You have heard the blasphemy.’” Mark 14:60-64
