Peter is not on board with this new revelation from Jesus. For the first time in his ministry Jesus is telling his disciples what he knows is the inevitable end he will meet. The miracles he has performed, the people he has touched, and even more importantly the good news he has proclaimed and the authority with which he has proclaimed it, is disturbing the usual order of things and that is only going to intensify.  Those who are comfortable with their position in the community are finding their comfort and power challenged.  Those who are used to setting the rules are finding their rules critiqued. Those who are used to interpreting the law of God are hearing new interpretations. And they don’t really like it.
