Shades of Grey - If you claim christ is the mediator and He is all we need for salavtion, why then did He entrust Peter ( a human) with the key to the kingdom?, why should peter be needed anyway after christ's departure. Let me quote the words of our lord jesus christ here and explain the reasons for handling the figurative key over to him
What were “the keys” entrusted to Peter?
Matt. 16:19, JB: “I will give you the keys of the kingdom of heaven: whatever you bind on earth shall be considered bound in heaven; whatever you loose on earth shall be considered loosed in heaven.”
In Revelation, Jesus referred to a symbolic key used by himself to open up privileges and opportunities to humans
Rev. 3:7, 8, JB: “Here is the message of the holy and faithful one who has the key of David, so that when he opens, nobody can close, and when he closes, nobody can open: . . . I have opened in front of you a door that nobody will be able to close.”
Peter used “keys” entrusted to him to open up (to Jews, Samaritans, Gentiles) the opportunity to receive God’s spirit with a view to their entering the heavenly Kingdom
Acts 2:14-39, JB: “Peter stood up with the Eleven and addressed them in a loud voice: ‘Men of Judaea, and all you who live in Jerusalem . . . God has made this Jesus whom you crucified both Lord and Christ.’ Hearing this, they were cut to the heart and said to Peter and the apostles, ‘What must we do, brothers?’ ‘You must repent,’ Peter answered ‘and every one of you must be baptised in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. The promise that was made is for you and your children, and for all those who are far away, for all those whom the Lord our God will call to himself.’”
Acts 8:14-17, JB: “When the apostles in Jerusalem heard that Samaria had accepted the word of God, they sent Peter and John to them, and they went down there, and prayed for the Samaritans to receive the Holy Spirit, for as yet he had not come down on any of them: they had only been baptised in the name of the Lord Jesus. Then they laid hands on them, and they received the Holy Spirit.” (Verse 20 indicates that Peter was the one taking the lead on this occasion.)
Acts 10:24-48, JB: “They reached Caesarea the following day, and Cornelius [an uncircumcised Gentile] was waiting for them. . . . Peter addressed them . . . While Peter was still speaking the Holy Spirit came down on all the listeners.”
If christ is all we need, why does Peter needs to bind anything here on earth, why was authority given to him? and what evidence do we have to prove otherwise that similar authority wasn't given to the genius in brooklyn since 1919 to care for the masters assets here on earth?
