This week before the beginning of Lent, we celebrate what is commonly known as "Transfiguration Sunday" - the time that Jesus climbed the mountaintop to pray, with disciples Peter, John and James. 

While he was in prayer, the appearance of his face changed and his clothes became blinding white. At once two men were there talking with him. They turned out to be Moses and Elijah—and what a glorious appearance they made! They talked over his exodus, the one Jesus was about to complete in Jerusalem.

Meanwhile, Peter and those with him were slumped over in sleep. When they came to, rubbing their eyes, they saw Jesus in his glory and the two men standing with him. When Moses and Elijah had left, Peter said to Jesus, “Master, this is a great moment! Let’s build three memorials: one for you, one for Moses, and one for Elijah.” He blurted this out without thinking.

While he was babbling on like this, a light-radiant cloud enveloped them. As they found themselves buried in the cloud, they became deeply aware of God. Then there was a voice out of the cloud: “This is my Son, the Chosen! Listen to him.” (Peterson's "The Message")
