This Sunday we go with Peter, James and John up the mountain to Jesus’ transfiguration. At the Transfiguration, Moses and Elijah appeared with the One who is the Light of Light Himself (Matt. 17:1–9). Jesus’ glory as God shines with brilliant splendor in and through His human nature. By this epiphany, our Lord confirmed the prophetic word (2 Pet. 1:16–21), revealing that He is the fulfillment of the Law and the Prophets. He manifested His majesty as the eternal Son of the Father, and He wonderfully foreshowed our adoption as sons (Collect). We who have been baptized into Christ’s body are given a glimpse of the glory that we will share with Him in the resurrection on the Last Day.
