Before we come to Mark 8:31 – 9:1, we need to be aware of one important event that took place immediately before our pericope.
Mark 8:27–30. After taking his disciples away to an area north of Galilee, Jesus asks them who they think he is. Peter, speaking on behalf of the disciples, answers You are the Christ
(Mark 8:29). This moment is a high point in the Gospel, since it is the first time that someone has correctly identified who Jesus is. As readers of Mark’s Gospel, we were told in the very first verse (Mark 1:1) that Jesus is the Christ, and we’ve been waiting since then to see who will finally figure out the truth. Jesus tells his disciples not to share this information because at the moment, they do not yet understand what Jesus must do as the Christ. The popular concept of the Christ among the Jews of that time involved political and revolutionary hopes of freedom from Roman rule and the establishment of a Jewish kingdom similar to that of King David.1 If all the crowds knew that Jesus was the Messiah, they would get in the way of him doing the work that he came to do.
31 And he began to teach them that the Son of Man must suffer many things and be rejected by the elders and the chief priests and the scribes and be killed, and after three days rise again.
