Roman Catholicism is the largest “professing” Christian denomination worldwide with over a billion members. In spite of the numbers, as pointed out many times before, the Roman Catholic Church is a false church embracing many teachings that sharply oppose “essential” biblical doctrine. Some of Rome’s anti-biblical teachings include Purgatory (which is a flat out denial of the sufficiency and infallible work of Christ alone); the worship of Mary (as well as other false Marian doctrines); and Rome’s denial of justification through “faith alone.”
It is unfortunate that many Christian leaders, who are either afraid and/or unaware of the basic teachings of Catholicism, stay utterly silent on the issue; or, even worst, they endorse the Catholic Church as a true Christian church! What happened to the divine command of Jude 3: “Contend earnestly for the faith, which was once for all handed down to the saints”?
The “Rock” of Matthew 16:18
“I also say to you that you are Peter, and upon this rock I will build My church; and the gates of Hades will not overpower it.”
This passage is the so-called hallmark proof-text that Rome uses to teach that Peter was the “rock” (and thus, the first “Pope”) upon which Christ built His church. This notion also spawned other false Catholic doctrines such as the “infallibility” of the Pope when speaking, ex cathedra—“from the throne”): We declare, say, define, and pronounce that it is absolutely necessary for the salvation of every human creature to be subject to the Roman Pontiff” (Pope Boniface VIII, papal bull, Unam Sanctam, A.D. 1302; emphasis added).
However, as with any text of Scripture, to arrive at a correct interpretation of the intended meaning, one must engage in a proper exegesis of that text. Hence, for any interpretation to be “biblically” accurate, it must be exegetically justified. Before examining this text in detail, we must consider two important points in Jesus’ response to Peter.
1. Peter’s confession was of divine origin, thus, not of himself: “flesh and blood did not reveal this to you, but My Father who is in heaven” (cf. Phil. 1:29), and, as we will argue,
2. According to Jesus, Peter’s confession that Jesus is “the Christ, the Son of the living God” is “the rock,” upon which Jesus will build His church. Conversely, Rome asserts that the “rock” upon which Jesus will build His church is the Apostle Peter, not his confession. This erroneous interpretation can be shown as (a) exegetically false and (b) historically problematic.
Exegetically. The phrase in question reads: kagō de soi legō hoti su ei Petros kai epi tautē tē petra oikodomēsō mou tēn ekklēsian (lit., “I also and to you say that you are Peter and upon this the rock I will build My [the] church”). Note the following:
The context, which surrounds Jesus’ statement to Peter in verse 18, starts in verses 13-15 with Jesus’ question to His disciples regarding His identity: “But who do you say that I am?” It is Peter’s response (v. 16), that is, his confession of who Jesus is (“the Messiah, the Son of the living God”) that prompts Jesus’ statement to Peter.
“You” vs “this the rock.” The singular second person personal pronoun, su (“you”) is in direct reference. Thus, Jesus here is directly addressing Peter: “I also say to you that you [su] are Peter.” Thus, Jesus said to him, not about him. Whereas the pronoun tautē (“upon this rock”) is a demonstrative pronoun, which has a third person significance, that is, it is in indirect address. “Indirect,” in that Jesus is not directly addressing or speaking to the rock, but rather He is speaking to Peter: “You [su] *direct address] are Peter and upon this [epi tautē, indirect address] rock I will build My church.”
Hence, the text differentiates between Peter, to whom Jesus is directly addressing and the “rock,” to which is indirectly addressed (“upon this rock”). If Jesus had meant what modern-day Catholics assert, He simply would have stated: “Upon you [su] I will build My church” or “You Peter are the rock,” but He did not. Rather, as the text literally reads: “upon this the rock [epi tautē tē petra] I will build My (the) church.” Main point: the indirect reference, “this the rock” (lit.), therefore, is other than the direct reference, Peter, who is being directly addressed in the preceding phrase—, which is also clear in the immediate context. Roman Catholics, however, cannot accept any doctrine contrary to the “infallible” position (ex cathedra) of their Ultimate Authority—Rome.
Historically. Most Roman Catholics are not aware of the historical research done by Roman Catholic Archbishop Peter Richard Kenrick regarding the early church’s view of Matthew 16:18. Archbishop Kenrick prepared a paper on this subject, which was to be delivered to Vatican I (1870). However, it was never delivered, but it was published later, along with other insights. He points out the 5 interpretations, which Fathers of antiquity held to: 1) Peter as the Rock, 17 Fathers, 2) all the apostles, 8 Fathers, 3) that the church was built on the faith that Peter confessed, 44 Fathers, including the most important Fathers, 4) Jesus as the Rock, 16 Fathers, and 5) all Christians were the living stones, held by very few Fathers. Kenrick rightfully concludes:
“If we are bound to follow the majority of the Fathers in this thing, then we are bound to hold for certain that the rock should be understood as the faith professed by Peter, not Peter professing the faith.”
Thus, only 20% of the Fathers held to Rome’s now canonized “infallible” “Petrine Rock” interpretation of Matthew 16:18. That is far from being the norm of the early church. As Roman Catholic apologist, H. Burn-Murdock admits: “None of the writings of the first two centuries describe St. Peter as a bishop of Rome.” In fact, no one before Callistus (A.D. 223) used Matthew 16:18 to support the primacy of the Roman bishop (i.e., “Pope” as Rome call it)—no one.
The church historian, Eusebius of Caesarea (A.D. 263-339), sees the “rock” as Christ. He links this interpretation with the parallel rock and foundation statements of 1 Corinthians 3:11 and 10:4. Sharing this view (Christ as the Rock) was Augustine. In fact, he commented more on Matthew 16:18 than any other church Father. It is true that at the beginning of his ministry, he saw Peter as the Rock. However, he changed his position throughout the balance of his ministry in which he adopted the view that the Rock was not Peter, but either Christ or Peter’s confession, which pointed to the Person of Christ:
Christ, you see, built his Church not on a man but on Peter’s confession. What is Peter’s confession? ‘You are the Christ, the Son of the living God.’ There’s the rock for you, there’s the foundation, there’s where the Church has been built, which the gates of the underworld cannot conquer (Sermons, XI, Sermon 229, 327).
What has been demonstrated over and over is that Roman Catholics do not engage in critical exegesis when interpreting Scripture, nor do they objectively examine the patristic (church Fathers) record, not because Catholics lack the ability, but because they do not need to—for Rome has already provided the “infallible” interpretation for them. Thus, for the Catholic: Rome’s interpretations are correct, because Rome says they are.
However, the following points seriously challenge Rome’s position of the so-called Primacy of Peter and him being the first Pope of Rome:
1) There is no biblical evidence indicating that Peter had supremacy over all the other apostles.
2) Peter never once considered that he was Pope, Pontiff; Vicar of Christ, Holy Father, or Head of the whole Christian Church, nor did any of the other apostles make such as claim.
3) Peter outwardly denied the Lord (out of fear) and Peter was rebuked by the Apostle Paul for being prejudice against the Gentiles (cf. Gal. 2:11-12).
4) At the first church council in Jerusalem (not Rome), it was James and not Peter who was the leading speaker and decision maker, for James authoritatively declared: “It is my judgment that we do not trouble those who are turning to God from among the Gentiles. . . .” (Acts 15:19). Moreover, the letter that was sent out regarding the judgment never mentions Peter (cf. v. 23).
5) At the end of Romans, Paul sends his greetings to at least 26 people—but Peter is not even mentioned! Why? Surely, if Peter had “recognized supremacy” over Rome and all the apostles, we would expect Paul to have greeted him first!
6) Peter was a married man, unlike the Roman Popes (cf, Matt. 8:14; 1 Cor. 9:5).
These are but a few of the many valid objections to Rome’s position. Simply, there is no place in the NT where Peter acted as “Pope,” or as the “supreme leader” or “head” of the apostles and the church. Quite the opposite is true. Paul says that the Christian church has “been built on the foundation of the apostles and prophets, Christ Jesus Himself being the cornerstone” (Eph. 2:20). The Christian confession that Jesus Christ is the Son of the living God is the very ROCK of faith upon which the Christian church has been built—and not upon the man Peter.
The religious belief of Rome is a “both-and” system: God’s Universal Plan- and man’s free will; faith and works; Jesus and Mary; the Cross and the perpetual sacrifices of Christ at the Mass; Biblical doctrine and the Church; Scripture and tradition. Thus, The Christ of Rome is anything, but, a Powerful Savior- The Christ of Rome Could not Save Alone- – “Shared” Cross Work
The word of God is both Scripture and tradition; salvation is by faith and works, nature (i.e., man’s own natural ability) and God, Mary and Jesus, and submitting to the ultimate religious authority, i.e., the Roman Pontiff (i.e. the Pope). Whereas biblical Christianity teaches that Scripture alone is our final authority, and salvation is by grace alone, through faith alone, by Christ alone, and for the glory of God alone—Soli Deo Gloria!
“By His doing [alone] you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption so that, just as it is written, “LET HIM WHO BOASTS, BOAST IN THE LORD” (1 Cor. 1:30-31).
 In 1870 (at Vatican I) Pope Pius IX proclaimed: “I am tradition” and hence, the Roman Catholic doctrine of the infallibility of the Pope (ex cathedra) emerged.
 In contrast to the teachings of Rome, salvation, faith, belief, repentance, etc. are grace-gifts granted by God alone. Hence, man does not cooperate or participate in God’s sole work of redemption, as Rome teaches. Salvation is God working alone—namely, monergistic (cf. John 1:13; 6:37-40; Acts 13:48; Rom. 8:29-30; 1 Cor. 30-31; Eph. 2:8-10; 2 Thess. 2:13).
 Although demonstrative pronouns (“this”/“that”) technically do not have “person,” they can express an indirect significance as with a third person pronoun, thus expressing a thing (“this”) other than the speaker (Jesus) or the one spoken to (Peter).
 Petros, “piece of rock.”
