Uh-huh…but I’m gonna be a real “PIA” and hound “SIA” for his answer…

Seems he often has some words to share, but he seems to be “evading” answering my question.
I think he should have the courtesy to answer…don’t you?
Okay, so, I’ve decided to weigh in on this because I’m a glutton for punishment. Our take on Matt 16:18. Feel free to respond, Rob:
In Jewish tradition, names were very important and functioned as titles that defined a person’s role in society. In fact, in the Jewish Torah, changing a persons name meant changing the persons spiritual status and mission. For example, when God established His covenant with Abram, God changed his name from Abram (which means “father” in Hebrew) to Abraham (which means “father of nations” or “chief of the multitude”). By changing his name, God changed Abraham’s mission from a chieftain of a family tribe to the spiritual father of the Jewish nation. God did the same thing with Jacob, in which he was appointed to be the founder of the 12 tribes of Israel, God changed Jacob’s name to Israel.
Jesus changed Simon’s name to “Petros” to designate his new spiritual role among the apostles, and the Jews would immediately understood it’s significance (this is the primary audience for Matthew). There is a clear exchange of titles between Simon Peter and Jesus. Simon calls Jesus “the Christ” and Jesus calls Simon “the Rock.”
Since Simon’s confession was elicited by Jesus’ question --“but who do you say that I am?” – Jesus is also telling Simon who he is as well. In other words… Since Simon revealed the true character and identity of Jesus (the Messiah and Son of God), Jesus revealed the true character and identity of Simon Peter (the foundation of the apostolic ministry).
The question now becomes
why did He change Simon’s name to Rock? One of our confessional documents, the Treatise on the Power and Primacy of the Pope, states: “As to the declaration: Upon this rock I will build My Church, certainly the Church has not been built upon the authority of man, but upon the Ministry of the confession which Peter made, in which he proclaims that Jesus is the Christ, the Son of God. He accordingly addresses him as a minister: Upon this rock, i.e., upon this ministry. Therefore he addresses him as a minister of this office in which this confession and doctrine is to be in operation, and says: Upon this rock, i.e., this preaching and ministry.”
Based on Simon’s confession of faith (and the first of the apostles and their representative to do so), Christ institutes Peter as the chief of the Ministry which is given to all of the apostles generally in Matthew 18. Christ is the capstone of the Church; Peter is the rock of the apostles, and the apostles collectively are the foundation of the Church. Paul himself states this in Ephesians 2:19-20: “The household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone.”
The apostolic ministry lays the foundations for the Church and we who are their descendents in faith build up the Church down successively through the ages culminating in the return of Christ.
What the passage
doesn’t establish is that the role given to the Rock is to continue past Peter’s lifetime in a successive papacy as Rome defines it. The apostles were given direct revelation through the Spirit and they wrote this revelation down in the scriptures. Their teachings left to us are the basis for our continued building of the Church.
