Enough of this “Peter’s Third Job” junk. Is that the latest way they teach you to attack the papacy and Peter’s office?

You need to understand the Bible. You need to understand the early church.
First let’s take a quick look at the Book Of Matthew (Matt from now on). I won’t go too deeply into, but just mention some things that people might not know. Matt is the first book of the Gospels, even though it was not written first. This is considered by many to be a deliberate move to show primacy, and to show the extremely important connectedness between Matt and the OT. Matthew was a Jew and an apostle of Jesus, writing in Aramaic to Jews. (that may sound obvious but it’s not—Matt was the only Gospel written directly to Jews).
So, which you’re well aware of, in Matt 16 we get:
13
When Jesus went into the region of Caesarea Philippi he asked his disciples, “Who do people say that the Son of Man is?”
14
They replied, “Some say John the Baptist, others Elijah, still others Jeremiah or one of the prophets.”
15
He said to them, “But who do you say that I am?”
16
11 Simon Peter said in reply, “You are the Messiah, the Son of the living God.”
17
Jesus said to him in reply, “Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my heavenly Father.
18
And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it.
19
I will give you the keys to the kingdom of heaven. Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven.”
So, Jesus is asking these guys “Who does everyone say that I am?” and then “Who do you guys say that I am?”
Peter is the one who says “You are the Messiah, the Son of the living God.”
Then a strange kind of moment. Peter doesn’t get credit for the answer, he gets credit for being blessed:
“Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my heavenly Father”
then Jesus says: “And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it.
19
I will give you the keys to the kingdom of heaven. Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven.”
(Interesting thing: This is the first of only two times that Jesus mentions the word church.)
And what about the "keys to the kingdom and power to bind and loose etc? This terminology would have profound meaning for Jews of that time.
They all knew exactly where he was coming from.
Governments all over the east at that time were based on the Egyptian monarchical form of government and all the heirarchy and positions were well understood. The Rabbinic terms “binding and loosing” were clear and meaningful as well, commonly used to describe religious, judicial, and legal authority. No mix up for these guys following Jesus.
Because of the Old Testament history, the prophetic words of Isaiah, and the teaching of the rabbis, all the Jews at that time knew exactly what Jesus and Matt are referring to: Royal authority, judicial authority.
Jesus refers to prophecy of Isaiah quite intentionally and everyone Jew in the land knew exactly what he was talking about.
On that day I will summon my servant Eliakim, son of Hilkiah;
21
I will clothe him with your robe, and gird him with your sash, and give over to him your authority. He shall be a father to the inhabitants of Jerusalem, and to the house of Judah.
22
I will place the key of the House of David on his shoulder; when he opens, no one shall shut, when he shuts, no one shall open.
23
I will fix him like a peg in a sure spot, to be a place of honor for his family;
Jesus doesn’t refer to stuff just out of a whim, I’d sure you’d agree.
Remember, David was the King of Israel and Judah and like all kings of Israel, Judah and the entire area appointed a royal steward who he handed the keys of the kingdom.
This person, the royal steward, who was handed the keys to the kingdom, was the second most person in charge and ruled the kingdom (over every other person incl the king’s relatives) in the king’s absence.
They actually used to use huge sets of keys to hand to this person in front of everyone in the palace to show the authority transfer.
Now the very, very cool thing is that the parallel goes a lot deeper than even what I’m referring to.
It actually goes back to Genesis and Joseph.
