"We had been eyewitnesses of his majesty." (2 Peter 1:16)

The Transfiguration stands as one of the greatest revelations of Jesus' divine identity before His Passion. The One whose face shines like the sun is the same One who will soon be disfigured on Calvary. Through this glorious event, the Father prepares the disciples to understand that the Cross is not a defeat but the path to glory. As St. Peter later testifies in today's second reading, "We had been eyewitnesses of his majesty." The apostles did not preach myths or legends; they proclaimed what they had personally seen and heard. An important question is why Jesus chose only Peter, James, and John to witness this extraordinary revelation. Throughout the Gospels, these three form Jesus' inner circle. They alone witness the raising of Jairus' daughter (Mk 5:37), the agony in Gethsemane (Mt 26:37), and now the Transfiguration. Peter, as the one chosen to become the visible head of the apostolic college (Mt 16:18-19), needed his faith strengthened so that he could later strengthen the faith of his brothers (Lk 22:32). The Church would be built upon his confession of faith, and therefore he first had to behold the glory of the One whom he confessed as "the Christ, the Son of the living God." The presence of James and John is equally significant. Shortly after this event, their mother would ask Jesus to grant her sons the places at His right and left in His Kingdom (Mt 20:20-23). Their ambition revealed that they still misunderstood the nature of Christ's kingdom, imagining it as one of earthly honor and privilege. By taking them up the mountain, Jesus begins to purify their understanding. The glory they witness is inseparable from the Cross they must later embrace. Indeed, the places at Christ's right and left are ultimately occupied not by ambitious disciples but by two criminals at Calvary. Jesus teaches James and John that true greatness is found not in power but in humble service and sacrificial love. The vision of glory is therefore not a reward for ambition but a preparation for discipleship. The appearance of Moses and Elijah carries profound theological meaning. Moses represents the Law, while Elijah represents the Prophets. Together they symbolize the entirety of God's revelation in the Old Testament. Their presence demonstrates that Jesus does not abolish the Law and the Prophets but brings them to their perfect fulfillment (Mt 5:17). The conversation between Moses, Elijah, and Jesus also reveals the unity of salvation history. Everything in the Old Covenant points toward Christ. After the Father's voice commands, "Listen to him," Moses and Elijah disappear, and "they saw no one but Jesus alone." This is not a rejection of the Law and the Prophets but a declaration that their purpose has reached its fulfillment in Christ, the definitive Word of God. From now on, every authentic interpretation of Scripture must lead to Him. Peter's desire to build three tents reflects the Jewish expectation of the messianic age and perhaps the Feast of Tabernacles. He wishes to remain on the mountain, prolonging the experience of glory. Yet discipleship does not end on the mountain. Jesus leads them back down into the valley where suffering, ministry, and eventually the Cross await. The Christian life likewise moves between moments of spiritual consolation and the daily demands of faithful discipleship. We cannot remain forever on the mountain of extraordinary experiences; we must carry the light of Christ into the ordinary circumstances of life. The Father's command remains the heart of today's Gospel: "This is my beloved Son... listen to him." In a world filled with competing voices, ideologies, and distractions, the Church continually points us to Christ as the Father's final and perfect revelation. The Transfiguration assures us that beyond every cross lies resurrection, beyond suffering lies glory, and beyond faithful discipleship lies eternal communion with God. Like Peter, may we become eyewitnesses, not merely of Christ's external glory, but of His transforming presence in our own lives, allowing His light to shine through us for the salvation of the world.
