You make some good points. Because this article is called “Peter and the Papacy”, where/when did Peter become Pope? Who refers to him as such? The RCC bills itself as the ONE TRUE SUPER Church founded upon the SUPER APOSTLE Peter. First Peter was “over” the other Apostles and that has been modified to “first among equals” - which means what exactly? If we move on to Chapter 18 (later) we still find the Apostles are internally wrestling over who is the greatest and Jesus addresses this. IF Peter was THE ROCK the Church was founded upon, now would be the time to clarify. Jesus needed the confessions/ministry of all twelve Apostles and treats no one greater/lesser than the other. Jesus dealt fairly and equally so there would be no dissent amongst them.
AND......
When James and John were asking Him to allow them to sit at His right hand, THAT would have been the time to clarify who was in charge, to tell them, *No, you guys. You all need to listen to Peter.* And He didn't.
And He told later them that when the HOLY SPIRIT came, HE would lead them into all truth, another time Jesus could have taken the opportunity to clarify instructions about Peter. And He didn't.
