The Transfiguration commemorates Christ's radiant manifestation of his divine glory to Peter, James, and John on Mount Tabor.
The Feast of the Transfiguration, celebrated on August 6th, commemorates the moment when Jesus revealed his divine glory to Peter, James, and John on a high mountain. This event strengthened the apostles' faith before the coming Passion and gives us a glimpse of our own future glory.
"After six days, Jesus took with him Peter, James, and John his brother, and brought them up into a high mountain by themselves. He was changed before them. His face shone like the sun, and his garments became as white as the light." — Matthew 17:1-3
Peter, overwhelmed by the vision, offered to build three tents. Then a bright cloud overshadowed them:
"While he was still speaking, behold, a bright cloud overshadowed them. Behold, a voice came out of the cloud, saying, 'This is my beloved Son, in whom I am well pleased. Listen to him." — Matthew 17:5-7
Tradition identifies Mount Tabor in Galilee as the site of the Transfiguration, though some scholars suggest Mount Hermon. A church has stood on Mount Tabor since at least the 4th century, and today the Church of the Transfiguration crowns its summit.
The appearance of Moses and Elijah represents the Law and the Prophets—the whole Old Testament—testifying to Christ. Luke tells us they "spoke of his departure (exodus), which he was about to accomplish at Jerusalem" (Luke 9:31). Jesus' coming death would fulfill all that Moses and the prophets foretold.
The Transfiguration reveals:
The feast has been celebrated on this date since at least the 5th century in the East. In the West, Pope Callistus III extended it to the universal Church in 1457, commemorating the Christian victory at Belgrade (1456) over the Ottoman Empire.
The Transfiguration encourages us on our spiritual journey. We walk by faith, not yet seeing Christ's full glory. But we have been given glimpses—in Scripture, in the sacraments, in prayer—that sustain us until we see him face to face.
"But we all, with unveiled face seeing the glory of the Lord as in a mirror, are transformed into the same image from glory to glory, even as from the Lord, the Spirit." — 2 Corinthians 3:18
