First Reading Daniel 7.9-10, 13-14
As I watched, thrones were set in place, and the One who is Ancient of Days took his throne. His clothing was white as snow, and the hair of his head like pure wool. His throne was fiery flames, and its wheels were burning fire. A stream of fire issued and flowed out from his presence. A thousand thousands served him, and ten thousand times ten thousand stood attending him. The court sat in judgment, and the books were opened.
As I watched in the night visions, I saw one like a son of man coming with the clouds of heaven. And he came to the One who is Ancient of Days and was presented before him.
To him was given dominion and glory and kingship, that all peoples, nations, and languages should serve him. His dominion is an everlasting dominion that shall not pass away, and his kingship is one that shall never be destroyed.
Psalm 97
The Lord is king, the most high over all the earth.
The Lord is king! Let the earth rejoice; let the many coastlands be glad! and thick darkness are all around him; righteousness and justice are the foundation of his throne.
The mountains melt like wax before the Lord, before the Lord of all the earth. The heavens proclaim his righteousness; and all the peoples behold his glory.
For you, O Lord, are most high over all the earth; you are exalted far above all gods.
Second Reading 2 Peter 1.16-19
We did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ, but we had been eyewitnesses of his majesty. For he received honour and glory from God the Father when that voice was conveyed to him by the Majestic Glory, saying, “This is my Son, the Beloved. With him I am well pleased.”
We ourselves heard this voice come from heaven, while we were with him on the holy mountain. So we have the prophetic message more fully confirmed. You will do well to be attentive to this as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts.
Gospel Matthew 17.1-9
Jesus took with him Peter and James and his brother John and led them up a high mountain, by themselves. And he was transfigured before them, and his face shone like the sun, and his clothes became dazzling white. Suddenly there appeared to them Moses and Elijah, talking with him.
Then Peter said to Jesus, “Lord, it is good for us to be here; if you wish, I will make dwellings here, one for you, one for Moses, and one for Elijah.”
While he was still speaking, suddenly a bright cloud overshadowed them, and from the cloud a voice said, “This is my Son, the Beloved; with him I am well pleased; listen to him!”
When the disciples heard this, they fell to the ground and were overcome by fear. But Jesus came and touched them, saying, “Get up and do not be afraid.” And when they looked up, they saw no one except Jesus himself alone.
As they were coming down the mountain, Jesus ordered them, “Tell no one about the vision until after the Son of Man has been raised from the dead.”
