The Transfiguration of Jesus is an episode in the New Testament narrative in which Jesus is transfigured (or metamorphosed) and becomes radiant upon a mountain. In these accounts, Jesus and three of his apostles go to a mountain (the Mount of Transfiguration). 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. Similar transfiguration occurred to St. Seraphim of Sarov.
