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

9:38 And John answered him, saying, Master, we saw one casting out devils in thy name, and he followeth not us: and we forbad him, because he followeth not us.
