[Just mythoughts]

The problem with most RC’s is that they confuse the rock as Peter and fail to understand the object of our Lord’s pronouncement was all those to who God the Father had spoken.

Well I would add that the 'keys' given to Peter are no longer used. Peter's keys no longer exist as was given by Christ. Right now Francis is cutting a new set of keys.

Where are you getting the faulty information that they keys of the kingdom no longer exist?

Strange. They were given to Peter by Christ. Why wouldn’t they exist in heaven where Peter opens and closes the gate?
