You have hit the nail on the head IMO and have driven it straight and true. What you mentioned is PRECISELY why I am astounded that people could seriously believe that Jesus singled out Peter for special status. That is EXACTLY what he was AVOIDING doing!!! All they way up to the Upper Room (the inspiration for the name of the community Bible fellowship I lead out in), the twelve were quarreling about who would have the highest position in the coming kingdom! James and John had just requested, through their mother, the two highest places, and their comrades were indignant! Of course, the text does not support the notion that Jesus either gave Peter a new name (He did not, he used the same moniker He had given Peter on day one) nor that Peter was the 'petra' as Jesus did NOT call Peter 'petra' OR build His church on Peter! Nor does the language, the grammar support the idea that the 'keys' specified in Mt. 16 were given EXCLUSIVELY to Peter. As well, the rest of the apostles were given the same powers in ch. 18. The word 'keys' DOES NOT need to be repeated. What is important is the description of the powers bestowed. It is identical to that in ch. 16. And, on top of all that, as you pointed out, Jesus' STRENUOUS efforts to take the attention OFF of position or seeking the highest place and urging them all instead to be servants and take the lowest place.
At any rate, so much for that. Thanks, Rick, for that incisive post.
