Mark is the earliest of the Gospels and contains much of the teachings of Peter. This Gospel presents Jesus as the man of power, the strong and active Son of God; its climax is reached when Peter makes his great confession, “You are the Christ.”

Mark 9

9:2 And after six days Jesus taketh with him Peter, and James, and John, and leadeth them up into an high mountain apart by themselves: and he was transfigured before them.
