I agree with some of it...
Super80: I agree with some of what you wrote, specifically:
"As long as we all agree on the Salvation afforded in Christ Jesus and act righteously from and in that faith, then matters of division between denominations among Christians are secondary."
However:
"Caesarea Philippi had a spring at the base of a rocky cliff face that fed into the Jordan River. In this rock wall there were recesses carved out and idols of Roman mythology adorning them. Jesus has brought the Disciples to this pagan center in their last circuit of the Holy Land together on their way to Jerusalem for Christ's crucifixion. In that setting, we can see a double entendre where Jesus is contrasting the pagan practices to the New Covenant He makes. Instead of having faith based on idols, Christian faith would be on Christ. Compared to the rock wall, Peter’s faith was the rock Jesus would build His Church upon. The Gospel account makes the distinction of calling Simon; Petros, the masculine, but what He will build the Church on is Petra, the feminine. The Bible uses marriage as an analogy in describing the Church, so this distinction in the Greek provides an insight to applicability of what the rock is in conveying the meaning behind Jesus' words in the Aramaic as understood by the Apostles -guided by the Holy Spirit- in conveying those Words of Jesus."
I can't agree with this. I have included some of the comments on this subject from Protestant Bible scholars. These are not Catholic priests conveying their opinion, or anyone you might assume would be biased towards the Catholic interpretation:

The meaning is, “You are Peter, that is Rock, and upon this rock, that is, on you, Peter I will build my church.” Our Lord, speaking Aramaic, probably said, “And I say to you, you are Kepha, and on this kepha I will build my church.” Jesus, then, is promising Peter that he is going to build his church on him! I accept this view. (New Testament Commentary: Exposition of the Gospel According to Matthew (Grand Rapids, MI: Baker, 1973), 647.)
Gerhard Maier
Leading conservative evangelical Lutheran theologian
Nowadays a broad consensus has emerged which – in accordance with the words of the text – applies the promise to Peter as a person. On this point liberal (H. J. Holtzmann, E. Schweiger) and conservative (Cullmann, Flew) theologians agree, as well as representatives of Roman Catholic exegesis.

Although it is true that petros and petra can mean “stone” and “rock” respectively in earlier Greek, the distinction is largely confined to poetry. Moreover the underlying Aramaic is in this case unquestionable; and most probably kepha was used in both clauses (“you are kepha” and “on this kepha”), since the word was used both for a name and for a “rock.” The Pe**CENSORED****CENSORED****CENSORED****CENSORED**ta (written in Syriac, a language cognate with Aramaic) makes no distinction between the words in the two clauses. The Greek makes the distinction between petros and petra simply because it is trying to preserve the pun, and in Greek the feminine petra could not very well serve as a masculine name. (The Expositor’s Bible Commentary: Volume 8 (Matthew, Mark, Luke), (Grand Rapids, MI: Zondervan, 1984), 368.)
The word Peter petros, meaning “rock” (Gk 4377), is masculine, and in Jesus’ follow-up statement he uses the feminine word petra (Gk 4376). On the basis of this change, many have attempted to avoid identifying Peter as the rock on which Jesus builds his church. Yet if it were not for Protestant reactions against extremes of Roman Catholic interpretations, it is doubtful whether many would have taken “rock” to be anything or anyone other than Peter. (Zondervan NIV Bible Commentary – New Testament, vol. 2, (Grand Rapids, MI: Zondervan, 1994), 78.)
John Peter Lange
German Protestant scholar
The Saviour, no doubt, used in both clauses the Aramaic word kepha (hence the Greek Kephas applied to Simon, John i.42; comp. 1 Cor. i.12; iii.22; ix.5; Gal. ii.9), which means rock and is used both as a proper and a common noun. . . . The proper translation then would be: “Thou art Rock, and upon this rock,” etc. (Lange’s Commentary on the Holy Scriptures: The Gospel According to Matthew, vol. 8, (Grand Rapids, MI: Zondervan, 1976), 293.)
John A. Broadus
Baptist author
Many insist on the distinction between the two Greek words, thou art Petros and on this petra, holding that if the rock had meant Peter, either petros or petra would have been used both times, and that petros signifies a separate stone or fragment broken off, while petra is the massive rock. But this distinction is almost entirely confined to poetry, the common prose word instead of petros being lithos; nor is the distinction uniformly observed.
But the main answer here is that our Lord undoubtedly spoke Aramaic, which has no known means of making such a distinction [between feminine petra and masculine petros in Greek]. The Pe**CENSORED****CENSORED****CENSORED****CENSORED**ta (Western Aramaic) renders, “Thou are kipho, and on this kipho.” The Eastern Aramaic, spoken in Palestine in the time of Christ, must necessarily have said in like manner, “Thou are kepha, and on this kepha.” . . . Beza called attention to the fact that it is so likewise in French: “Thou art Pierre, and on this pierre”; and Nicholson suggests that we could say, “Thou art Piers (old English for Peter), and on this pier.” (Commentary on the Gospel of Matthew, (Valley Forge, PA: Judson Press, 1886), 355-356.)

By the words “this rock” Jesus means not himself, nor his teaching, nor God the Father, nor Peter’s confession, but Peter himself. The phrase is immediately preceded by a direct and emphatic reference to Peter. As Jesus identifies himself as the Builder, the rock on which he builds is most naturally understood as someone (or something) other than Jesus himself. The demonstrative this, whether denoting what is physically close to Jesus or what is literally close in Matthew, more naturally refers to Peter (v. 18) than to the more remote confession (v. 16). The link between the clauses of verse 18 is made yet stronger by the play on words, “You are Peter (Gk. Petros), and on this rock (Gk. petra) I will build my church.” As an apostle, Peter utters the confession of verse 16; as a confessor he receives the designation this rock from Jesus. (“Matthew,” Evangelical Commentary on the Bible, (Grand Rapids, MI: Baker, 1989), 742.)

Baptist and Professor of New Testament, Denver Seminary
Acknowledging Jesus as The Christ illustrates the appropriateness of Simon’s nickname “Peter” (Petros = rock). This is not the first time Simon has been called Peter (cf. John 1:42), but it is certainly the most famous. Jesus’ declaration, “You are Peter,” parallels Peter’s confession, “You are the Christ,” as if to say, “Since you can tell me who I am, I will tell you who you are.” The expression “this rock” almost certainly refers to Peter, following immediately after his name, just as the words following “the Christ” in v. 16 applied to Jesus. The play on words in the Greek between Peter’s name (Petros) and the word “rock” (petra) makes sense only if Peter is the rock and if Jesus is about to explain the significance of this identification. (The New American Commentary: Matthew, vol. 22, (Nashville: Broadman, 1992), 251-252.)

On this rock I will build my church: the word-play goes back to Aramaic tradition. It is on Peter himself, the confessor of his Messiahship, that Jesus will build the Church. The disciple becomes, as it were, the foundation stone of the community. Attempts to interpret the “rock” as something other than Peter in person (e.g., his faith, the truth revealed to him) are due to Protestant bias, and introduce to the statement a degree of subtlety which is highly unlikely.
