Pope Benedict had some very interesting points of reflection in this chapter. The first half of the chapter he puts the main focus on Peter and his confession to Jesus. Pope Benedict points out how Peter’s reaction to Jesus after catching the abundance of fish, when told to cast out into the deep, is really man’s reaction when coming into contact with the Divine. Peter realizes that this catch of fish is miraculous and he immediately realizes that the power of God had come in contact with him, a lowly fisherman. He does not know how to act in front of the Divine so he asks Jesus to depart from his presence.
In the second half of this chapter, Pope Benedict reflects on the Transfiguration of Jesus on the mountain. He makes a beautiful comparison of Moses receiving the Torah on Mount Sinai and Jesus being the Torah.
