Gospel according to Saint Luke 9,28-36
Jesus took Peter, John and James and went up the mountain to pray. And while He was praying, the aspect of his face was changed and his clothing became dazzling white. Two men were talking with Jesus: Moses and Elijah. They had just appeared in heavenly glory and were telling him about his departure that had to take place in Jerusalem.
Peter and his companions had fallen asleep, but they awoke suddenly and saw Jesus’ Glory and the two men standing with him. As Moses and Elijah were about to leave, Peter said to him, «Master, how good it is for us to be here for we can make three tents, one for you, one for Moses and one for Elijah». For Peter didn’t know what to say. And no sooner had he spoken than a cloud appeared and covered them; and the disciples were afraid as they entered the cloud. Then these words came from the cloud, «This is my Son, my Chosen one, listen to him». And after the voice had spoken, Jesus was there alone. The disciples kept this to themselves at the time, telling no one of anything they had seen.
