When Jesus said that Peter would be the rock on which his church was built, I really don't think he intended it to be the Mother of All Bureacracies!
It defies reason, admittedly not always a reliable guide, to contemplate that Jesus might build His church on any person. Even human reason, and some appreciation for the innate fallibility of man, should compel us to know that Jesus intended/intends to build His church on the truth of Peter’s perceptive confession.
For those that believe any mortal man is the foundation of the Christian church, I pray for your conversion.
