On This Rock, Peter, I Will Build My Church

Peter is named Peter after the Petra in a sort of his name is kind of an adjective. His name is not intended to be understood as Christ calling him the rock, but rather he's sort of a rock or he's rocky or he's made of rock Or he's in some relation to the rock in virtue of his confession of faith. When Christ tells Peter, you are Peter and on this rock, I agree with Augustine's reading that on this rock does not refer to Peter, but rather to Christ himself. The final time that Peter is mentioned by name in Matthew's gospel is when he curses Jesus and three times and denies him. After that, Peter is not mentioned by name.
