Daniel 7: 9- 10, 13- 14
7:9 I watched until thrones were set up, and the ancient of days sat down. His garment was radiant like snow, and the hair of his head like clean wool; his throne was flames of fire, its wheels had been set on fire.
7:10 A river of fire rushed forth from his presence. Thousands upon thousands ministered to him, and ten thousand times hundreds of thousands attended before him. The trial began, and the books were opened.
7:13 I watched, therefore, in the vision of the night, and behold, with the clouds of heaven, one like a son of man arrived, and he approached all the way to the ancient of days, and they presented him before him.
7:14 And he gave him power, and honor, and the kingdom, and all peoples, tribes, and languages will serve him. His power is an eternal power, which will not be taken away, and his kingdom, one which will not be corrupted.
Second Reading
The Second Letter of Saint Peter 1: 16-19
1:16 For it was not by following fanciful doctrines that we made known to you the power and presence of our Lord Jesus Christ, but we were made eyewitnesses of his greatness.
1:17 For he received honor and glory from God the Father, whose voice descended to him from the magnificent glory: “This is my beloved Son, in whom I am well pleased. Listen to him.”
1:18 We also heard this voice conveyed from heaven, when we were with him on the holy mountain.
1:19 And so, we have an even firmer prophetic word, to which you would do well to listen, as to a light shining within a dark place, until the day dawns, and the daystar rises, in your hearts.
Gospel
Luke 9: 28- 36
9:28 And it happened that, about eight days after these words, he took Peter and James and John, and he ascended onto a mountain, so that he might pray.
9:29 And while he was praying, the appearance of his countenance was altered, and his vestment became white and shining.
9:30 And behold, two men were talking with him. And these were Moses and Elijah, appearing in majesty.
9:31 And they spoke of his departure, which he would accomplish at Jerusalem.
9:32 Yet truly, Peter and those who were with him were weighed down by sleep. And becoming alert, they saw his majesty and the two men who were standing with him.
9:33 And it happened that, as these were departing from him, Peter said to Jesus: “Teacher, it is good for us to be here. And so, let us make three tabernacles: one for you, and one for Moses, and one for Elijah.” For he did not know what he was saying.
9:34 Then, as he was saying these things, a cloud came and overshadowed them. And as these were entering into the cloud, they were afraid.
9:35 And a voice came from the cloud, saying: “This is my beloved son. Listen to him.”
9:36 And while the voice was being uttered, Jesus was found to be alone. And they were silent and told no one, in those days, any of these things, which they had seen.
