Well, which is it? Because if it is something that developed over time, then clearly it was not something handed down by the apostles via oral tradition. If it was understood by the apostles, then Mr. Boncore’s explanation does not hold water and his portrayal of the Council of Jerusalem is a sham.
If we are speaking here of whether Peter was the head of the Church, then, yes, it was understood and taught by the Apostles. The Council of Jerusalem provides evidence of this.
- If it is by way of these figurative keys that binding and loosing occurs (according to your own words), AND
- Christ gave this power to all of his disciples (Matthew 18:18), THEN
- Does it not stand to reason that the other disciples also have these keys?
You have already said you disagree with the logic and quoted others which take the same stance. I am not looking for agreement, however, but rather how you have determined the logic to be flawed that led to your disagreement. In other words, is your disagreement based purely on the disagreement of others or is your disagreement based on reason?
I think this is simple enough. I do not hold that Peter had the authority to bind and loose
by virtue of his having the keys. Indeed, Matthew 18 clearly tells us that all of the apostles had this authority. (This actually tells us more about their infallibility as apostles than it does about Peter’s position.)
Instead, Peter held the keys as the symbol of his position as the royal steward in the kingdom that Jesus re-established as the heir to the Davidic throne.
Peter – The Royal Steward
Jesus gave Peter the “keys of the kingdom of heaven”. In ancient times, a king might choose a second in command (known as the royal steward or prime minister) who literally wore a large key as a symbol of his office and who spoke with the authority of the king. The prophet Isaiah confirms this:
"In that day I will summon my servant, Eliakim son of Hilkiah. I will clothe him with your robe and fasten your sash around him and hand your authority over to him. He will be a father to those who live in Jerusalem and to the house of Judah.
I will place on his shoulder the key to the house of David; what he opens no one can shut, and what he shuts no one can open.” (Isaiah 22:22)
In the passage above, God is speaking, and He confirms the existence of the office, the key, and the continuation of the office despite the change of office holder. In other words, the
office of the royal steward continued even when the man who held the office died or was replaced by someone else. God Himself passes the key from one steward to the next.
In the New Testament, we learn that Jesus inherits the throne of his father, David.
Luke 1:31–33
And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. He will be great, and will be called Son of the Most High; and the Lord God will give to him the throne of his father David, and he will reign over the house of Jacob forever; and of his kingdom there will be no end.
We also read the following:
Matthew 16:13-19
When Jesus came to the region of Caesarea Philippi, he asked his disciples, “Who do people say the Son of Man is?” They replied, “Some say John the Baptist; others say Elijah; and still others, Jeremiah or one of the prophets.” “But what about you?” he asked. “Who do you say I am?” Simon Peter answered, “You are the Christ, the Son of the living God.” Jesus replied, "Blessed are you, Simon son of Jonah, for this was not revealed to you by man, but by my Father in heaven. And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.
The passage quoted above from Matthew tells us that Jesus named Peter as His royal steward and gave him the “keys to the kingdom of heaven" as the symbol of his authority to speak in His name. Since Jesus is an eternal king, the office of royal steward in His kingdom will never. Peter died as a martyr as Jesus foretold, and the successors of Peter have taken his place in the eternal office that Jesus established in His royal court.
In addition to the reference to a key or keys, note the following parallels:
"What he opens no one can shut, and what he shuts no one can open.” (Is. 22:22)
"Whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.” (Mt. 16:19)
Jesus specifically referenced the passage from Isaiah when He appointed Peter. Peter has received authority from Jesus to speak in His name. To do so faithfully, Peter must not teach error; therefore, Peter (and his successors who hold the office) are protected by God through the charism of infallibility.
In closing, let me add that while all the apostles were individually infallible when teaching formally on matters of faith and morals, only Peter held the office that exists in perpetuity. Thus, only Peter’s successor (who likewise holds the keys) is individually infallible.
