The Transfiguration of Jesus is an event reported in the New Testament when Jesus is transfigured and becomes radiant in glory upon a mountain. The Synoptic Gospels (Matthew 17:1–8, Mark 9:2–8, Luke 9:28–36) describe it, and the Second Epistle of Peter also refers to it (2 Peter 1:16–18). It has also been hypothesized that the first chapter of the Gospel of John alludes to it (John 1:14).
In these accounts, Jesus and three of his apostles, Peter, James, John, go to a mountain (the Mount of Transfiguration) to pray. On the mountain, Jesus begins to shine with bright rays of light. Then the prophets Moses and Elijah appear next to him and he speaks with them. Jesus is then called “Son” by a voice in the sky, assumed to be God the Father, as in the Baptism of Jesus.
Many Christian traditions, including the Eastern Orthodox, Roman Catholic and Anglican churches, commemorate the event in the Feast of the Transfiguration, a major festival.
