Peter himself refers to Jesus as the Rock on which the church is built.
And he calls believers living stones and a holy priesthood, again, not putting himself in any special position of authority.
It doesn’t matter whether it was Aramaic or Greek; Peter himself contradicts the Roman Catholic idea that Jesus is making him a special rock.
I understand what you’re saying and I 100% agree. However, there remains the issue of Providence. I.e.: the ability of God to direct circumstances, versus God as a helpless or disinterested bystander who allows things to happen willy nilly.
Clearly the Bible teaches that God is in control. This doesn’t mean that He overrides the gift of freewill that He bestowed when He made man in His image. But it does mean that He causes all things to work together for the good of those who love Him and who are called according to His purpose.
Since this promise is true, it can be stated with complete and utter certitude that the selection of Greek for the transmission of the divinely inspired NT mss was NOT happenstance. Rather, Greek was the language purposefully and specifically chosen by God. That is the only position consistent with God’s Providence and God’s promises.
As noted upthread, there is an obvious reason for God’s selection. Namely, the fact that Greek is one of—if not THE—most precise languages in existence. By using this language, God minimized murkiness and ambiguity. As anyone who has studied Greek knows, the language embodies a veritable genius for clarity and precision. It is not an overstatement to posit that one factor in “the fullness of time,” was exactly the widespread use of the Greek language. It was and is singularly ideal for clearly communicating the sometimes complex and difficult teachings of the Nt.
