Sirach, first off, the Peshitta is a translation of the original Greek from the 2nd century. So to argue that the Peshitta shows the true intent while the original Greek does not is a big stretch. That being said, I do not deny that Jesus told Peter those words in Aramaic. My point though is that Christ had already often spoken of the faith as being the rock for people to build their houses on etc. So Peter knew that Christ was referring to his faith as the basis of the Church, not Peter himself.
Jesus Christ did not appoint a successor. He is the head of his Church. Find me any of the Church Fathers who declare that Christ appointed a successor. You will not find it. Nor does the papacy go as far as to declare itself the successor of Christ.
As for your Aaron example, I’ve looked and looked and you’ve never referenced what exactly about Aaron you are trying to say other than that his priesthood was of the highest authority. I won’t dispute that historical fact. However, I see that it has very little to do with the New Covenant. Furthermore, did the not prophets, by virtue of the Holy Spirit, supersede the authority of the priesthood of the Old Covenant? By all indications they did.
Again, with Luke 22:32, you are referring to the Peshitta as though it is more authoritative than the Greek original. It is not. Both the Greek and the Latin understand “confirm” as to mean “strengthen.” You’re adding a meaning of authority that simply isn’t there or isn’t apparent.
Grammar does not distort the true meaning. God chose Matthew to write his gospel. Matthew, through the guidance on the Holy Spirit, intentionally wrote it in Synagogue Greek. Being literate, Matthew was very conscious of proper grammar. Greek and Latin both take gender case very seriously especially since the languages lack a strong sentence structure and contain no articles. Proper grammar is therefore imperative for communication to even be possible.
When looking at Ephesians ii. 19-20 The verses are:
“Now then you are not strangers and foreigners: but you are citizens of the saints, and the domesticals of God, built upon the foundation of the Apostles and Prophets, JESUS Christ himself being the highest corner stone.” “Corner stone” is, of course, a different metaphor from “foundation stone.” Christ is at once the Architect i.e., the Builder., of the Church and the “corner stone” holding it together. But He built it upon the Apostles and Prophets as foundation stones, Peter being the “foundation rock” upon which Christ based the whole of His building. That is the sense of the words, “Thou art Peter, and upon this rock I will build my Church.” And such is the only interpretation sound scholarship will permit.
So the actual translation of Mt. 16:18 is:
ܐܳܦ݂ ܐܶܢܳܐ ܐܳܡܰܪ ܐ݈ܢܳܐ ܠܳܟ݂ ܕ݁ܰܐܢ݈ܬ݁ ܗ݈ܽܘ ܟ݁ܺܐܦ݂ܳܐ ܘܥܰܠ ܗܳܕ݂ܶܐ ܟ݁ܺܐܦ݂ܳܐ ܐܶܒ݂ܢܶܝܗ ܠܥܺܕ݈݁ܬ݁ܝ ܘܬ݂ܰܪܥܶܐ ܕ݁ܰܫܝܽܘܠ ܠܳܐ ܢܶܚܣܢܽܘܢܳܗ܂
Literally,
“And I say to thee: That thou art a rock; and upon this rock I will build my church, and the gates of sheol shall not prevail against it.”
First off, why would there need to be two rocks? Is the rock of Christ alone not sufficient? Again, you make my case. You’ve cited scripture that shows that Christ is the rock. And then you add on another interpretation that Peter is a rock too and assume that it is clear and academically indisputable.
As for your Aramaic translation from the Peshitta, Aramaic seems to lack articles too. Various translations of the verse therefore yield very different implications. And because Aramaic lacks the gender distinction between the two usages of “rock” it becomes even less clear.

Lastly, petros is a word in Greek. It is just that by the time of Koine, it had the exact same meaning as “petra.”
