I notice two things in these replies.
1) a general misunderstanding of the papacy. The papacy is not a replacement of Jesus nor claimed to be. Rather it is believed to be representative. the church (catholic church) is believed to be the fulfillment of gods kingdom on earth. [not saying its true, just explaining]
2) a complete lack of address to the part where Jesus says, whatever you loose on Earth shall be loosed in heaven & whatever you bind on earth shall be bound in heaven.
#1.The papacy should not even exist.It goes against all teachings in the holy scriptures.It never existed in Jesus time or after when the disciples were spreading the truth.
#2.Then he bestowed on Peter some very important privileges in that congregation. He did not give Peter primacy over the other apostles, as some have assumed, but he gave him responsibilities. He gave Peter “the keys of the kingdom.” (Matt. 16:19) It would be Peter’s privilege to open the hope of entering God’s Kingdom to three different fields of mankind—first to the Jews, then to the Samaritans, and finally to the Gentiles, or non-Jews.
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.” (Ac 8 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.”
Did heaven wait on Peter to make decisions and then follow his lead?
Acts 2:4, 14, JB: “They were all filled with the Holy Spirit, and began to speak foreign languages as the Spirit gave them the gift of speech. . . . Then [after Christ, the head of the congregation, had stirred them up by means of the holy spirit] Peter stood up with the Eleven and addressed them.” (See Ac 2 verse 33.)
Acts 10:19, 20, JB: “The Spirit had to tell him [Peter], ‘Some men have come to see you. Hurry down, and do not hesitate about going back with them [to the home of the Gentile Cornelius]; it was I who told them to come.’”
Compare Matthew 18:18, 19.
Is Peter the judge as to who is worthy to enter the Kingdom?
2 Tim. 4:1, JB: “Christ Jesus . . . is to be judge of the living and the dead.”
2 Tim. 4:8, JB: “All there is to come now is the crown of righteousness reserved for me, which the Lord [Jesus Christ], the righteous judge, will give to me on that Day; and not only to me but to all those who have longed for his Appearing.”
