So is Peter like the mayor and the other apostles heroes/celebrities ?
No, you missed the point. I was only pointing out the historical support for the Catholic interpretation of the symbolic meaning behind handing over of keys to someone and how that history carries over even to this day.
The others did the same things of loosening /binding or remitting/retaining sins,
No, they did not all bind and loose – forgiveness of sins and binding/loosening are referring to two things. Jesus gave them all the command that who’s sins they forgive/not forgive are forgiven/not forgiven, but only directly to Peter did he give the keys and power to bind/loosen. The bind/and loosen is referring to infallibility, something that come from the Holy Spirit.
Peter spoke infallibly in Acts 15 about the matter brought before them. James then confirms it’s infallible (the truth) and shows everyone (from scripture/history) why. If anyone from that point on taught differently, they were not in communion with the church, because they were not preaching the truth.
Mark 28:1 says “All authority is given me in heaven AND EARTH, go therefore and teach all nations baptizing them, ,teaching them what I command you,…I am with you …” Is a Vicar needed here ? A prime minister ?
Yes, as a matter of fact a vicar is needed, otherwise Jesus would not have had a need to appoint anyone, not even the apostles to their positions. He would have just wrote a book and handed it out to everyone and said, “here, read this, everything you need to know is in there.” No ‘keys’ were given to anyone but Peter.
Do we need to interpret a human form to this promised Vicar of Christ himself and the Holy Ghost ?
God came to us as a man-- as Jesus the Christ, and appointed men to leadership roles in His Holy Church, and to preach the good news. The Holy Spirit, the Spirit of Truth (not deceit) speaks through the men of His Church (this is part of having faith in Jesus, to believe all of his promises, and one was that he would send his Holy Church the Holy Spirit so that the Truth would always be with Her). So, yes, we need good men, good stewards, who are entrusted with the truth by God to teach us and to guide us, so that we don’t fall victim to Satan and all his lying and deceitful ways.
(Yes Peter was a leader ,but because he was a leader, not because of more authority)
A parable depicts the owners son as being sent to the owners vineyard for payment. This parallels Isaiah 22. You don’t think the father “deputized” the Son ? Jesus is both prime minister and king , He is all . I do not think His first visit to us was as "king of kings’ , yet He is and shall be.
Prime minister might be fine given the role of a prime minister, but I believe it would be more accurate to call Peter a steward.
Jesus appointed Peter to be a steward (vicar), and he had the responsibility of overseeing the flock. In a monarch, a steward was an official who was appointed by the legal ruling monarch to represent him or her in a country, and may have a mandate to govern it in his or her name; in the latter case, it roughly corresponds with the position of governor or deputy (the Roman rector, praefectus or
vicarius [root and origin of the English word “vicar”]). It was also a term used to refer to the chief servant of a landed estate.
A steward (as vicar/chief steward) doesn’t do anything on his own, but whatever the King commanded him to do, and he has authority over other servants and stewards and has the responsibility of taking care of all that belongs to the king (we belong to the King, and so the vicar, the stewards, and the servants take care of us). While the king is away (at the right hand of the Father), the vicar, the stewards, and servants tend to the flock until the King returns, and the vicar overseas it all. We are all called to be servants, and stewards and some have been called to be vicar, but all are called by the Holy Spirit. Some are given more responsibilities and some less, but all are appointed by the Holy Spirit. Whoever is given more responsibility, more is expected of him (Luke 12:48).
BTW, Matthew 20:8-16, and it is the steward that pays the laborers, carrying out his masters wishes, tending to the vineyard. They complain about the owner because he had his steward pay people who came later a full days wage, the same as those who worked all day. There are lessons in there, but this is long enough so I won’t elaborate on it.
