Did you read my followup post (#37) that I addressed to Gaelic? I said, in part, “I think it is apolegetic gymnastics to completely remove Peter from the “you are rock” statement.”According to wiki, the term “cephas” in Syriac or Aramaic means, “stone, ball, clump, chew,” and “rock” is a connotation. However, the Greek word “Petra” means, “grown rock, rocky range, or cliff.”
Our Lord changed Simon’s name. Simon was previously known as Simon Barjona (Barjona meaning son of John). I recall a priest explaining in a catechism class that when God changed a name in the OT, it signified an important event, but I can’t now recall the two or three examples he mentioned.
So Our Lord changed Simon’s name from Simon Barjona to Simon Peter, or rather, Simon the Rock. It was upon the Rock of Peter that Our Lord would build His Church. I think that this is a proper Catholic teaching. Though John was first in love, Simon Peter was almost always given precedence by Our Lord for leadership among the twelve. He singled Peter out as the leader in many instances. I can give examples from my catechism class notes for this. This may not be sufficient proof for non-Catholics, but it makes sense to me.
I don’t deny the special leadership role that St. Peter played. I also don’t believe that this necessarily translates into all that those in communion with the Bishop of Rome claim it does for the successors of St. Peter.
