Which Protestants said it was stupid to give Peter the name of *rock*? Can you point to the infallible declaration to that position?
It’s called a “Straw Man” argument. You attribute an opinion or point of view to your opponent and destroy the false argument.
It’s easier than dealing with valid arguments.
My point is this:
If Protestants are going to insist that there’s no connection between the name “Rock” and the statement that “upon this Rock I will build my Church,” then it is incumbent on them to explain how Jesus could have been so stupid as to create an opening for the Catholic Church to drive a truck through.
