Catholics claim that the name “Peter” comes from the Latin word meaning “Rock.” It seems legitimate until one looks ahead a little bit [i:3iz3m4kr]Simon Peter replied, “You are the Christ, the Son of the living God.” And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.” ~Matthew 16:16-17[/i:3iz3m4kr] All in all, the Church was founded on the rock-like faith Peter had. It was built on “the ministry of the confession Peter made, in which he proclaims that Jesus is the Christ, the Son of God.” (Tr 25)[/quote:3iz3m4kr]
Again, it’s not based [b:3iz3m4kr][i:3iz3m4kr]on[/i:3iz3m4kr][/b:3iz3m4kr] Scripture, but on events that [b:3iz3m4kr][i:3iz3m4kr]preceded[/i:3iz3m4kr][/b:3iz3m4kr] Scripture.
It does not come from Latin either, but rather Greek (in the New Testament) by way of Aramaic which was spoken by Jesus (and in which the word remains untranslated in another part of the gospels).
I wrote about the issue previously here: http://www.aboutcatholics.com/worship/origin_papacy/
There are also numerous other passages that demonstrate the primacy of Peter amongst the apostles (a practice that was well established by the time the gospels were written).
