I am?" The disciples provide a variety of the common hypotheses at the time. Jesus then asks his disciples about their own opinion: But who do you say that I am? Only Simon Peter answers him: You are the Christ, the Son of the living God. In Matthew 16:17 Jesus blesses Peter for his answer, and later indicates him as the rock of the Church, and states that he will give Peter "the keys of the kingdom of heaven". In blessing Peter, Jesus not only accepts the titles Christ and Son of God which Peter attributes to him, but declares the proclamation a divine revelation by stating that his Father in Heaven had revealed it to Peter. In this assertion, by endorsing both titles as divine revelation, Jesus unequivocally declares himself to be both Christ and the Son of God. The proclamation of Jesus as Christ is fundamental to Christology and the Confession of Peter, and Jesus's acceptance of the title is a definitive statement for it in the New Testament narrative. While some of this passage may well be authentic, the reference to Jesus as Christ and Son of God is likely to be an addition by Matthew. Transfiguration 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. The Synoptic Gospels (Matthew 17:1–9, Mark 9:2–8, Luke 9:28–36) describe it, and 2 Peter 1:16–18 refers to it. 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. 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. Thomas Aquinas 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, Crucifixion, Resurrection, and Ascension. In the New Testament, Transfiguration is a pivotal moment, and the
