What makes you think he spoke aramaic? The common tongue of the day was a form of greek.
You mean other than the fact that Jesus called Peter, “Simon Bar-Jonah”?'And Jesus answered him, “Blessed are you, Simon Bar-Jona! For flesh and blood has not revealed this to you, but my Father who is in heaven. And I tell you, you are Peter, and on this rock I will build my church, and the powers of death shall not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.” (Matthew 16:17-19)“Bar-Jona” being the Aramaic expression for 'Son of Jona"?
Or that Jesus said, “You are Simon son of John. You will be called
Cephas” (which, when translated, is Peter)."? (John 1:42)
“Cephas” is Aramaic for “rock” which John translates for us as “Petros” or “Peter” in English.
Yet in the greek text (preportedly authorized by the church herself) it reads “you are petras and on this petros shall I buil my church”.
This can easily be read, as declaring that christ will build the church on his father, and the truth revealed thereby, while making Peter a part of that process.
PROTESTANT SCHOLARS ON PETER THE ROCK
“This is not a name, but an appellation and a play on words. There is no evidence of Peter or
Kephas as a name before Christian times….
Peter as
Rock will be the foundation of the future community. Jesus, not quoting the Old Testament, here uses Aramaic, not Hebrew, and so uses the only Aramaic word that would serve his purpose. In view of the background of v. 19…one must dismiss as confessional interpretation any attempt to see
this rock as meaning the faith, or the messianic confession, of Peter. To deny the pre-eminent position of Peter among the disciples or in the early Christian community is a denial of the evidence…The interest in Peter’s failures and vacillations does not detract from this pre-eminence; rather, it emphasizes it. Had Peter been a lesser figure his behavior would have been of far less consequence.” (Protestant scholars W.F. Albright and C.S. Mann,
The Anchor Bible; Matthew [Garden City, N.Y.: Doubleday & Co., 1971], 195)
“It is on Peter himself, the confessor of his Messiahship, that Jesus will build the Church…Attempts to interpret the ‘rock’ as something other than Peter in person (e.g., his faith, the truth revealed to him) are due to Protestant bias, and introduce to the statement a degree of subtlety which is highly unlikely.” (Presbyterian minister David Hill,
The Gospel of Matthew, New Century Bible Commentary [Grand Rapids, MI: Eerdmans, 1972], 261)
Even if I am wrong, you still have not connected Peter with the papacy, nor have you validated papal succession, nor have you even come close to proving what you claim to be truth.
I recently did exactly this in another thread entitled "Apostolic Succession in the Catholic Church. You may wish to review and comment there.
