Mark’s Gospel, Ch. 8: Jesus + Wrong Interest = Incorrect Jesus?
Here’s a popular passage that many Christians should be familiar with (Mark 8:27-29):
Jesus and his disciples went on to the villages around Caesarea Philippi. On the way he asked them, “Who do people say I am?” They replied, “Some say John the Baptist; others say Elijah; and still others, one of the prophets.” “But what about you?” he asked. “Who do you say I am?” Peter answered, “You are the Messiah.” 
Peter’s confession here is a major declaration in the lens of orthodox Christian doctrine and church history. This is the second time in Mark’s Gospel (the first being at the beginning of the Gospel) where Jesus is indicated to be the Messiah. This is also one high point in Mark’s Gospel in terms of narrative and character formation (for both Jesus and the disciples). Peter, speaking for the disciples, finally get who Jesus is (despite having trouble understanding his parables). Jesus is blatantly declared to be the Messiah by characters within the story, not just the narrator. This sets the tone for the rest of the Gospel - Jesus’ ministry in Jerusalem and what it means to follow the Messiah.
