Personally I don’t know any Catholic who believes that. We recognise all those baptised with water in the name of the Father, Son & Holy Ghost to be christians who possess some of the Truth. We believe the CC holds the fullness of Truth. Obviously many Protestants do not believe the Catholic Church is infallible in it’s teachings.
How do I know the Church is infallible? You mean how do I know the Church’s Teachings are infallible? The word* infallible* in the Catholic context can only ever be used to describe how the Teachings (Doctrine) of the Magisterium are without error.
**How do I know the Church’s Teachings are infallible? Some reasons are below, can’t list all due to time constraints:
- Everything rests with authority** given by Jesus (keys to Heaven) to Peter and passed from Peter to Linus and so and so on and onto Francis…Matt 16:19
- Apostolic succession from the Apostles replacing Judas with Matthias who laid hands over and ordained bishops and so and so on…Acts 1: 21-22
- Teaching authority passed from Jesus to Peter (Matt 16:19) and ALL the Apostles (whatever you bind on earth is bound in Heaven and whatever you loose on earth is loosed in Heaven)…Matt 18:18.
Binding is an ancient term used by Rabbis for religious Teachings.
- The Gates of Hell will not prevail against the rock (Kepha/Peter) upon which Jesus built his Church…Matthew 16:18
- Jesus asks Peter 3 times to watch over his flock…John 21:15-17
- Isaiah 22 also confirms the role of the papacy.
"What’s happening here in Isaiah 22? Well, in verse 19 it says, “I will thrust you from your office and you will be cast down from your station and on that day I will call my servant Eliakim, the son of Hilkiah, and I will clothe him with your robe and will bind your girdle on him and will commit your authority to his hand, and he shall be a father to the inhabitants of Jerusalem and to the House of Judah; and I will place on his shoulder the key of the House of David.”
Now the House of David is like, you know, the House of Bourbon. It’s a dynastic reference. The House of David is the Davidic kingdom, the Davidic dynasty. We know this because David has been dead for hundreds of years when this is happening in Isaiah 22, “I will give you the key of the House of David. He shall open and none shall shut, and he shall shut and none shall open. He will become a throne of honor to his father’s house.” Look at all of the symbols of dynastic authority that are being given to this individual. First of all, an office. Second, a robe. Third, a throne and fourth, keys, the key of the House of David, these royal keys.
Now, what is going on here? I’ll just summarize it in rather simple terms. Hezekiah was at the time, the king over Israel. He was the son of David, hundreds of years after David had died. He was in the line of David and also he was ruler over the House of David. Now all kings in the ancient world had, as kings and queens have these days, cabinet officers, a cabinet of royal ministers. Like David Cameron is the Prime Minister, so there are other ministers under the Queen in Great Britain. Hezekiah, as King, had as his Prime Minister before Shebna who proved unworthy. So he was expelled, but when he was expelled, he left an office vacant. Not only did you have dynastic succession for the king, but you also have a dynastic office for the Prime Minister. When Shebna is expelled, there is an empty office that needs to be filled and that’s why Eliakim is called to fill it.
Now, Eliakim is a minister in the cabinet, but now he is being granted the Prime Minister’s position. How do we know? Because he is given what the other ministers do not have, the keys of the kingdom, the key to the House of David. That symbolized dynastic authority entrusted to the Prime Minister and dynastic succession. Why? Because it’s the key of David; it’s the House of David.
Let me go back and try to simplify this even further. I’ll read the quote. Albright says, “In commenting upon Matthew 16 and Jesus giving to Peter the keys of the kingdom, Isaiah 22:15 and following undoubtedly lies behind this saying.” Albright, a Protestant, non- Catholic insists that it’s undoubtable that Jesus is citing Isaiah 22, “The keys are the symbol of authority and DeVoe rightly sees here the same authority as that vested in the vicar, the master of the house, the chamberlain of the royal household of ancient Israel.” In other words, the Prime Minister’s office.
Other Protestant scholars admit it too, that when Jesus gives to Peter the keys of the kingdom, Peter is receiving the Prime Minister’s office, which means dynastic authority from the Son of David, Jesus, the King of Israel, but also an office where there will be dynastic succession."
