This homily by Fr. Matthew Howell was given at St. Herman Church on the feast of the Transfiguration. He discusses how this is a feast of the vision of God, how the vision of God comes through the suffering of the Cross and ascending of the mountain of God (purification), and how this all pertains to our life with Christ in all eternity.
2 Peter 1:10-19
BRETHREN, be more zealous to confirm your call and election, for if you do this you will never fall; so there will be richly provided for you an entrance into the eternal kingdom of our Lord and Savior Jesus Christ. Therefore I intend always to remind you of these things, though you know them and are established in the truth that you have. I think it right, as long as I am in this body, to arouse you by way of reminder, since I know that the putting off of my body will be soon, as our Lord Jesus Christ showed me. And I will see to it that after my departure you may be able at any time to recall these things. For we did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ, but we were eyewitnesses of his majesty. For when he received honor and glory from God the Father and the voice was borne to him by the Majestic Glory, “This is my beloved Son, with whom I am well pleased, ” we heard this voice borne from heaven, for we were with him on the holy mountain. And we have the prophetic word made more sure. You will do well to pay attention to this as to a lamp shining in a dark place, until the day dawns and the morning star rises in your hearts.
At that time, Jesus took with him Peter and James and John his brother, and led them up a high mountain apart. And he was transfigured before them, and his face shone like the sun, and his garments became white as light. And behold, there appeared to them Moses and Elijah, talking with him. And Peter said to Jesus, “Lord, it is well that we are here; if you wish, I will make three booths here, one for you and one for Moses and one for Elijah.” He was still speaking, when lo, a bright cloud overshadowed them, and a voice from the cloud said, “This is my beloved Son, with whom I am well pleased; listen to him.” When the disciples heard this, they fell on their faces, and were filled with awe. But Jesus came and touched them, saying, “Rise, and have no fear.” And when they lifted up their eyes, they saw no one but Jesus only. And as they were coming down the mountain, Jesus commanded them, “Tell no one the vision, until the Son of man is raised from the dead.”
