The Transfiguration of Jesus is an episode in the New Testament narrative in which Jesus is transfigured and becomes radiant in glory upon a mountain.
Jesus and three of his apostles, Peter, James and John, go to a mountain (the Mount of Haramon). 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.
The Transfiguration is one of the miracles of Jesus in the Gospels. This miracle is unique among others that appear in the Canonical gospels, in that the miracle happens to Jesus himself.Thoomas Aqinas considered the Transfiguration “the greatest miracle” in that it complemented baptism and showed the perfection of life in Heaven. The Transfiguration is one of the five major milestones in the gospel narrative of the life of Jesus , the others being Baptism, Crucification, Resurrection and Ascension. In 2002,Pope John Paul II introduced the Luminous Mysteries in the Rosary, which includes the Transfiguration.
In Christian teachings, the Transfiguration is a pivotal moment, and the setting on the mountain is presented as the point where human nature meets God: the meeting place for the temporal and the eternal, with Jesus himself as the connecting point, acting as the bridge between heaven and earth.
