Hey, you are really funny!
If Peter had been given these revelations by the risen Christ, you would have a completely different position. But alas, he did not. He was given the Kingdom Gospel to preach, and that he did, until Israel was blinded and set aside. You as a Gentile, should have true respect for God's choice in Paul. Once Israel was set aside, gentiles were without hope, as our blessings were to come through Israel as God's agency on earth. They were to be a kingdom of priests to the nations.
Thank God He saved Paul and gave to him the ministry of reconciliation, and the gospel of the grace of God whereby we are all equal before God's eyes. And we are all saved by belief on the finished work of Christ, and that alone.
I'll let you in on another reason to respect Paul as God's agent to us in this dispensation: "The preaching of the Jesus Christ according to the revelation of THE MYSTERY, which was kept SECRET SINCE THE WORLD BEGAN, but NOW is made manifest.." Rom 16:25,26. This was not given to Peter and the 11, or to John the Baptist, or to anyone else until it was revealed to Paul by DIRECT REVELATIONS OF JESUS CHRIST.
Keys to the Kingdom? Binding and loosing? Retaining and remitting sins? All given to Peter and the 11 for the Kingdom that was to be set up on earth when Christ returns. Popes and bishops and magisterium? All given by men in order to attempt to carry out a commission that has been set aside until God begins to deal with Israel as a nation again.
Search the Epistles, search God's direct revelations to Paul, search the proof that Paul gave that Jesus Christ spoke to him face to face and mouth to mouth for those revelations for a new dispensation concerning not a Kingdom of Believers, but a Body of Believers.
You shortchange the very person that Jesus Christ chose to bring this age of grace to an unbelieving world.
