Matthew 16:18-20
Jesus instituted a preistly hierarchy in His Church. He started by making Peter the earthly head of the church with the power to bind and lose. If Peter or future holders of his office choose to bind certain practices related to the celebration of the Mass then they are binding.
And it was an office He gave Peter - read the verses in Matthew then read about Shebna in Isaiah. Jesus was creating an office. On this the scripture is clear.
Peters use of “keys” was an affirmation of decisions already made in heaven. Both the record in Acts and the Greek that Jesus’ words were recorded in reflect that.
The word priests is not applied to any within the Christian church while on earth. None. As heavenly rulers they are termed priests AND kings.

GALATIANS 2:
11 But when Peter was come to Antioch, I withstood him to the face, because he was to be blamed.
12 For before that certain came from James, he did eat with the Gentiles: but when they were come, he withdrew and separated himself, fearing them which were of the circumcision.
13 And the other Jews dissembled likewise with him; insomuch that Barnabas also was carried away with their dissimulation.
14 But when I saw that they walked not uprightly according to the truth of the gospel, I said unto Peter before them all, If thou, being a Jew, livest after the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews?
