The keys and bindings were for The Church Age, and Peter was given the honor of this 'opening the mystery' of the Ekklesia because of his profession revealed to him by the Holy Spirit. The 'opening act' is seen in Acts 2, the Day of Pentecost, fifty days after the Passover. [See Romans 16: 25&26, and Ephesians 3:3-7]
Jesus did not appoint Peter to be the 'papa' of the Ekkelsia. Jesus gave Peter the honor of opening the doorway for the Ekklesia who are Saved by Faith in Jesus The Christ.
okay. I suppose you believe Peter is the only honored with these keys, right? Did any of the others ever profess Jesus was the Christ and Messiah? God plays favorites?
