That is a common misunderstanding of Scripture. The Rock upon which the church (not the RCC, the invisible church comprised of those are saved by Christ) is the Lord Jesus.
See Ephesians chapter 2:
“11 Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands;
12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world:
13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
And the privileges and blessings of the gospel
14 For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us;
15 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace;
16 And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:
17 And came and preached peace to you which were afar off, and to them that were nigh.
18 For through him we both have access by one Spirit unto the Father.
19 Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;
20 And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;
21 In whom all the building fitly framed together groweth unto an holy temple in the Lord:
22 In whom ye also are builded together for an habitation of God through the Spirit.”
And the letter from Peter, 1 Peter chapter 1:
“1 Pet 1:1 Peter, an apostle of Jesus Christ, to the strangers scattered throughout Pontus, Galatia, Cappadocia, Asia, and Bithynia,
2 Elect according to the foreknowledge of God the Father, through sanctification of the Spirit, unto obedience and sprinkling of the blood of Jesus Christ: Grace unto you, and peace, be multiplied.
3 Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead.
4 To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you,
5 Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
17 And if ye call on the Father, who without respect of persons judgeth according to every man’s work, pass the time of your sojourning here in fear:
18 Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers;
19 But with the precious blood of Christ, as of a lamb without blemish and without spot:
20 Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,
21 Who by him do believe in God, that raised him up from the dead, and gave him glory; that your faith and hope might be in God.”
and on into Chapter 2:
“2:1 Wherefore laying aside all malice, and all guile, and hypocrisies, and envies, and all evil speakings,
2 As newborn babes, desire the sincere milk of the word, that ye may grow thereby:
3 If so be ye have tasted that the Lord is gracious.
4 To whom coming, as unto a living stone, disallowed indeed of men, but chosen of God, and precious,
5 Ye also, as lively stones, are built up a spiritual house, an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
6 Wherefore also it is contained in the scripture, Behold, I lay in Sion a chief corner stone, elect, precious: and he that believeth on him shall not be confounded.
7 Unto you therefore which believe he is precious: but unto them which be disobedient, the stone which the builders disallowed, the same is made the head of the corner,
8 And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient: whereunto also they were appointed.
9 But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should show forth the praises of him who hath called you out of darkness into his marvellous light:
10 Which in time past were not a people, but are now the people of God: which had not obtained mercy, but now have obtained mercy.”
Well, it's a vexed disagreement at least. But the upstate returns aren't in yet and the disagreement is not resolved.
But I don't see that holding that Peter has a unique role in the Church necessarily contradicts our Lord's position as Head of the body. Consequently, the marvelous texts you adduce, together with the simple declaration, "... He is the head of the body, the church ..." from Colossians 1:12-20 which we recite weekly (more or less) in evening prayer do not seem to be to contradict Peter's role.
I do think it comes down to a disagreement about the nature of "apostolicity" or "vicariate". Al Gore may have thought that being VICE-president entitled him to be president some day, and some popes have certainly allowed God to be usurped in their personal lives, but in general we don't teach that Peter or anybody supplants Christ as head of the body, the church.
FWIW.
The Lord said , “...and there shall be ONE FOLD and ONE SHEPHERD.” John 10:16, ……. That way the truth will be transmitted faithfully because our souls depend on it. The problem with Protestantism is that you have as many interpretations of the Bible as you have churches. Your argument is the same old argument against the Primacy of Peter. But YOUR views do not square with recorded history, which is a good thing since my salvation depends on the accurate transmission of the true Gospel. Not your version. I am confident God has not come down from on high and gave you a “new” revelation. But now I am beginning to understand why your church leaders preach to you ‘sola scriptura’, that way you don’t get bogged down doing research that might change your faith.
Mark 3:16; John 1:42 – Jesus renames Simon “Kepha” in Aramaic which literally means “rock.” This was an extraordinary thing for Jesus to do, because “rock” was not even a name in Jesus’ time. Jesus did this, not to give Simon a strange name, but to identify his new status among the apostles. When God changes a person’s name, He changes their status.
Gen. 17:5; 32:28; 2 Kings 23:34; Acts 9:4; 13:9 - for example, in these verses, we see that God changes the following people’s names and, as a result, they become special agents of God: Abram to Abraham; Jacob to Israel, Eliakim to Jehoiakim, Saul to Paul.
2 Sam. 22:2-3, 32, 47; 23:3; Psalm 18:2,31,46; 19:4; 28:1; 42:9; 62:2,6,7; 89:26; 94:22; 144:1-2 - in these verses, God is also called “rock.” Hence, from these verses, non-Catholics often argue that God, and not Peter, is the rock that Jesus is referring to in Matt. 16:18. This argument not only ignores the plain meaning of the applicable texts, but also assumes words used in Scripture can only have one meaning. This, of course, is not true. For example:
1 Cor. 3:11 - Jesus is called the only foundation of the Church, and yet in Eph. 2:20, the apostles are called the foundation of the Church. Similarly, in 1 Peter 2:25, Jesus is called the Shepherd of the flock, but in Acts 20:28, the apostles are called the shepherds of the flock. These verses show that there are multiple metaphors for the Church, and that words used by the inspired writers of Scripture can have various meanings. Catholics agree that God is the rock of the Church, but this does not mean He cannot confer this distinction upon Peter as well, to facilitate the unity He desires for the Church.
Matt. 16:18 - Jesus said in Aramaic, you are “Kepha” and on this “Kepha” I will build my Church. In Aramaic, “kepha” means a massive stone, and “evna” means little pebble. Some non-Catholics argue that, because the Greek word for rock is “petra”, that “Petros” actually means “a small rock”, and therefore Jesus was attempting to diminish Peter right after blessing him by calling him a small rock. Not only is this nonsensical in the context of Jesus’ blessing of Peter, Jesus was speaking Aramaic and used “Kepha,” not “evna.” Using Petros to translate Kepha was done simply to reflect the masculine noun of Peter.
Moreover, if the translator wanted to identify Peter as the “small rock,” he would have used “lithos” which means a little pebble in Greek. Also, Petros and petra were synonyms at the time the Gospel was written, so any attempt to distinguish the two words is inconsequential. Thus, Jesus called Peter the massive rock, not the little pebble, on which He would build the Church. (You don’t even need Matt. 16:18 to prove Peter is the rock because Jesus renamed Simon “rock” in Mark 3:16 and John 1:42!).
Matt. 16:17 - to further demonstrate that Jesus was speaking Aramaic, Jesus says Simon “Bar-Jona.” The use of “Bar-Jona” proves that Jesus was speaking Aramaic. In Aramaic, “Bar” means son, and “Jonah” means John or dove (Holy Spirit). See Matt. 27:46 and Mark 15:34 which give another example of Jesus speaking Aramaic as He utters in rabbinical fashion the first verse of Psalm 22 declaring that He is the Christ, the Messiah. This shows that Jesus was indeed speaking Aramaic, as the Jewish people did at that time.
Matt. 16:18 - also, in quoting “on this rock,” the Scriptures use the Greek construction “tautee tee” which means on “this” rock; on “this same” rock; or on “this very” rock. “Tautee tee” is a demonstrative construction in Greek, pointing to Peter, the subject of the sentence (and not his confession of faith as some non-Catholics argue) as the very rock on which Jesus builds His Church. The demonstrative (“tautee”) generally refers to its closest antecedent (“Petros”). Also, there is no place in Scripture where “faith” is equated with “rock.”
Matt. 16:18-19 - in addition, to argue that Jesus first blesses Peter for having received divine revelation from the Father, then diminishes him by calling him a small pebble, and then builds him up again by giving him the keys to the kingdom of heaven is entirely illogical, and a gross manipulation of the text to avoid the truth of Peter’s leadership in the Church. This is a three-fold blessing of Peter - you are blessed, you are the rock on which I will build my Church, and you will receive the keys to the kingdom of heaven (not you are blessed for receiving Revelation, but you are still an insignificant little pebble, and yet I am going to give you the keys to the kingdom).
Matt. 16:18-19 – to further rebut the Protestant argument that Jesus was speaking about Peter’s confession of faith (not Peter himself) based on the revelation he received, the verses are clear that Jesus, after acknowledging Peter’s receipt of divine revelation, turns the whole discourse to the person of Peter: Blessed are “you” Simon, for flesh and blood has not revealed this to “you,” and I tell “you,” “you” are Peter, and on this rock I will build my Church. I will give “you” the keys to the kingdom, and whatever “you” bind and loose on earth will be bound and loosed in heaven. Jesus’ whole discourse relates to the person of Peter, not his confession of faith.
“The blessed apostle Peter, in his successors, has handed down what he received. Who would be willing to separate himself from the doctrine of whom the Master himself instructed first among the apostles?” Pope Sixtus III, [regn A.D. 432-440], To John of Antioch (A.D. 433).
“But this mysterious function the Lord wished to be indeed the concern of all the apostles, but in such a way that He has placed the principal charge on the blessed Peter, chief of all the Apostles: and from him as from the Head wishes His gifts to flow to all the body: so that any one who dares to secede from Peter’s solid rock may understand that he has no part or lot in the divine mystery.” Pope Leo the Great [regn. A.D.440-461], Epistle 10 (A.D 445).
“And so he too rejoices over your good feeling and welcomes your respect for the Lord’s own institution as shown towards the partners of His honour, commending the well ordered love of the whole Church, which ever finds Peter in Peter’s See, and from affection for so great a shepherd grows not lukewarm even over so inferior a successor as myself.” Pope Leo the Great [regn. A.D.440-461], Sermon 2 (A.D ante 461).
“Stephen, that he who so boasts of the place of his episcopate, and contends that he holds the succession from Peter, on whom the foundations of the Church were laid...Stephen, who announces that he holds by succession the throne of Peter.” Pope Stephen I [regn. A.D. 254-257], Firmilian to Cyprian, Epistle 74/75:17 (A.D. 256).
“I beseech you, readily bear with me: what I write is for the common good. For what we have received from the blessed Apostle Peter s, that I signify to you; and I should not have written this, as deeming that these things were manifest unto all men, had not these proceedings so disturbed us.” Pope Julius [regn. A.D. 337-352], To the Eusebians, fragment in Athanasius’ Against the Arians, 2:35 (c. A.D. 345).
“For the good of unity Blessed Peter deserved to be preferred before the rest, and alone received the keys of the Kingdom of Heaven, that he might communicate them to the rest.” Optatus of Mileve, The Schism of Donatists, 7:3 (c.A.D. 367).
“Number the bishops from the See of Peter itself. And in that order of Fathers see who has succeeded whom. That is the rock against which the gates of hell do not prevail” Augustine, Psalm against the Party of Donatus, 18 (A.D. 393).
“I am held in the communion of the Catholic Church by...and by the succession of bishops from the very seat of Peter, to whom the Lord, after His resurrection commended His sheep to be fed up to the present episcopate.” Augustine, Against the Letter of Mani, 5 (A.D. 395).
“The chair of the Roman Church, in which Peter sat, and in which Anastasius sits today.” Augustine, Against the Letters of Petillian, 2:51 (A.D. 402).
“Although the tradition of the Fathers has attributed to the Apostolic See so great authority that none would dare to contest its judgments...For (Peter) himself has care over all the Churches, and above all that in which he sat nor does he suffer any of its privileges or decisions to be shaken” Pope Zosimus [regn A.D. 417-418 ],To Aurelius and the Council of Carthage, Epistle 12 (A.D. 418).
“The rising pestilence was first cut short by Rome, the see of Peter, which having become the head to the world of the pastoral office, holds by religion whatever it holds not by arms.” Prosper of Aquitaine, Song on the Enemies of Grace, 1 (A.D. 429).
