Just to add to Usagi comments above.
Where in the Bible does it say that Jesus did away with the succession for the King’s Vicar ? And if He was wanting to do away with it, then why give the Keys to only Peter. The word “you” below is in the singular in the Greek
**** “ … and the gates of the netherworld shall not prevail against it. I will give you the keys to the kingdom of heaven.”**
So, even when Peter dies the netherworld, or death, would not prevail. This is because another person is appointed to that position of the holder of the keys.
And again, if Jesus was not wanting this role of the Papacy to have succession, then why did Jesus make an allusion to a singular position that did have a successor in the Old Testament ?
****“Thus says the Lord, the GOD of hosts: Up, go to that official, Shebna, master of the palace… 19 I will thrust you from your office and pull you down from your station. On that day I will summon my servant Eliakim, son of Hilkiah; 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. 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. I will fix him like a peg in a sure spot, to be a place of honor for his family …”
Eliakim becomes the holder of the Keys, and so becomes the vicar, or the regent, or also called the “master of the palace” who ruled as an agent or representative for the king.
Cf. 1 Kings 18:3,4 2 Kings 10:5, and 15:5
What is a Key ?
To understand the significance of Jesus giving to Peter the Keys of the Kingdom of Heaven we need to think about the importance that keys have. To do this we need to reflect on the significance of what a lock does. For example, if everyone had keys to a given lock then that lock would serve absolutely no purpose at all. It would keep no one out. A lock only has value because only one key works. Only one particular key (or set of duplicate keys,) out of the whole range of different possibilities of possible keys, can open that given lock. Therefore, whoever holds the keys to a given lock has the UNIQUE position of being able to open that lock.
