After six days Jesus took Peter, James, and John his brother, and led them up a high mountain by themselves. And he was transfigured before them; his face shone like the sun and his clothes became white as light. And behold, Moses and Elijah appeared to them, conversing with him. Then Peter said to Jesus in reply, “Lord, it is good that we are here. If you wish, I will make three tents here, one for you, one for Moses, and one for Elijah.” While he was still speaking, behold, a bright cloud cast a shadow over them, then from the cloud came a voice that said, “This is my beloved Son, with whom I am well pleased; listen to him.” When the disciples heard this, they fell prostrate and were very much afraid. But Jesus came and touched them, saying, “Rise, and do not be afraid.” And when the disciples raised their eyes, they saw no one else but Jesus alone. As they were coming down from the mountain, Jesus charged them, “Do not tell the vision to anyone until the Son of Man has been raised from the dead.”
Matthew 17:1-9 (NABRE)
It is interesting that Jesus commands silence regarding the Transfiguration until after His Resurrection. However, knowing what we do know, this episode makes much more sense with that kind of contextualization.
Much happens in a short period of time. Jesus converses with Moses and Elijah, and the Father speaks for the first time since the Baptism of His Son. Jesus reveals to Peter, James, and John the glory that is to come, but we may be left with the question of why it was necessary to give a preview anyway.
These revelations are not anything that God needs for Himself. He is not dependent on anyone and, unlike fallen human beings, does not have to have an ego requiring fame and flattery as fuel. All that He does for us is purely for us, and in so doing He glorifies Himself, not out of any sort of deprivation, but because it is who He is, a glorious God.
This preview of the glory yet to come is not shown because Jesus wants to put on an unnecessary, self-centered display of power. Had He desired to do so, would He not have gathered a larger crowd than just three disciples situated on an isolated mountaintop? On the contrary, this preview is for us. As humans, we need reminders, for our memories are finite and often beset by frailties. We have the Bible and hear, week after week, readings at Mass that remind us of God’s steadfast love that has endured throughout salvation history and will continue to do so for an eternity.
So Jesus lets his disciples know that the hardships He will endure in His Passion will not be pointless. Peter, James, and John must have known of the stories of Moses and Elijah, who each experienced tremendous hardship in their lives but were eventually saved by God. Perhaps, as they grieved after Good Friday, the disciples recalled this episode and were strengthened by the hope that Jesus will return in glory.
Thank you for reading. Peace.
