Though Luke depends on Mark for this scene of Peter’s confession, he has made some significant changes in order to bring out his meaning of the text. The first is that unlike Mark, Luke does not give the geographical location (Caesarea Philippi), but gives instead the context of the prayer of Jesus. Through this change, Luke makes the confession a spiritual experience. Luke also changes Marks, “one of the prophets” to “one of the old prophets has risen.” Though the difference does not appear to be great, it is for Luke. In the Gospel of Luke, before Jesus everything is old. Jesus makes all things new. Luke has also eliminated Peter’s refusal to accept Jesus as the suffering Messiah and the rebuke of Peter by Jesus. Luke avoids narrating Marcan texts that show Peter and even the disciples in a bad light.
The second question to the disciples, “But who do you say that I am?” shows on the one hand that the answers given of the crowd’s understanding of Jesus are inadequate, and on the other that Jesus wants to know their understanding of him. In all the Synoptic Gospels it is Peter who answers, but here too Luke adds to Mark’s, “You are the Christ”, the words “of God”. The Greek word “Christos” means in English “the anointed” and this conveys the meaning of royalty. However, by his addition, Luke also brings in the prophetical dimension of Jesus’ person and mission. This prophetical dimension is explicated in the verses, which follow the confession of Peter, in which Jesus explains the kind of Christ/Messiah/Anointed One that he will be. The reason for the rebuke or “stern order” not to tell anyone is because Jesus wanted to avoid any misunderstanding of the term which could be understood only in the glorious sense. Jesus as “the Christ of God” will come in glory, but only after he has gone to the cross, died, been buried and then raised.
