This is the clue to your (and sadly, far too many others') error...
Error appealing to error does not make truth.

The SOURCE is SCRIPTURE!
Matt. 14:23-27: St. Peter is uniquely empowered by Jesus to walk on water, and when his faith begins to falter, our Lord does not allow him to go under. This is a prelude to Jesus promising to give his authority that can never fail to Peter in Matt. 16. The gift of the papacy is here assured not to depend upon the person of St. Peter or of his successors, but on the promise and power of Christ.
Matt. 17:24-27: After receiving the promise of authority in Matt. 16, St. Peter is once again given supernatural power to provide for both himself and Jesus when the first-century equivalent of the I.R.S. comes calling! Peter acts as Christ’s “vicar” or in the place of Jesus in miraculous fashion guaranteed by Jesus not to fail.
Argue with THAT!
Surely you are not claiming that God was not in the habit of anointing and appointing leaders? The Old Testament is full of such appointments. And if Jesus did not appoint Peter, to whom did Jesus give the keys of the kingdom? Who has them?
