28 About eight days later Jesus took Peter, John, and James up on a mountain to pray. 29 And as he was praying, the appearance of his face was transformed, and his clothes became dazzling white. 30 Suddenly, two men, Moses and Elijah, appeared and began talking with Jesus. 31 They were glorious to see. And they were speaking about his exodus from this world, which was about to be fulfilled in Jerusalem. 32 Peter and the others had fallen asleep. When they woke up, they saw Jesus' glory and the two men standing with him. 33 As Moses and Elijah were starting to leave, Peter, not even knowing what he was saying, blurted out, "Master, it's wonderful for us to be here! Let's make three shelters as memorials -one for you, one for Moses, and one for Elijah." 34 But even as he was saying this, a cloud overshadowed them, and terror gripped them as the cloud covered them. 35 Then a voice from the cloud said, "This is my Son, my Chosen One. Listen to him." 36 When the voice finished, Jesus was there alone. They didn't tell anyone at that time what they had seen.

Commentary on Luke 9:28-36
(Read Luke 9:28-36)
Christ's transfiguration was a specimen of that glory in which he will come to judge the world; and was an encouragement to his disciples to suffer for him. Prayer is a transfiguring, transforming duty, which makes the face to shine. Our Lord Jesus, even in his transfiguration, was willing to speak concerning his death and sufferings. In our greatest glories on earth, let us remember that in this world we have no continuing city. What need we have to pray to God for quickening grace, to make us lively! Yet that the disciples might be witnesses of this sign from heaven, after awhile they became awake, so that they were able to give a full account of what passed. But those know not what they say, that talk of making tabernacles on earth for glorified saints in heaven.
