Not only that, but the RCC cult was founded on a lie. If you read the original Greek and Hebrew you will see that Jesus did not say He would found His Church on Peter. What He said was that He would found His Church on Peter's confession that Jesus was the Son of God. Why would Jesus found His Church on a sinner?
To make it perfectly clear its divine, not human, origin, and that it survives on divine assistance, not human merit. Thanks for asking.
Let's begin with beethovenfan's question: "What about the “zombie-dogma” that Peter was the first pope?"
There is ample evidence in the New Testament that Peter was first in authority among the apostles. Whenever they were named, Peter headed the list (Matt. 10:1-4, Mark 3:16-19, Luke 6:14-16, Acts 1:13); sometimes the apostles were referred to as "Peter and those who were with him" (Luke 9:32). Peter was the one who generally spoke for the apostles (Matt. 18:21, Mark 8:29, Luke 12:41, John 6:68-69), and he figured in many of the most dramatic scenes (Matt. 14:28-32, Matt. 17:24-27, Mark 10:23-28). On Pentecost it was Peter who first preached to the crowds (Acts 2:14-40), and he worked the first healing in the Church age (Acts 3:6-7). It is Peter’s faith that will strengthen his brethren (Luke 22:32) and Peter is given Christ’s flock to shepherd (John 21:17). An angel was sent to announce the resurrection to Peter (Mark 16:7), and the risen Christ first appeared to Peter (Luke 24:34). He headed the meeting that elected Matthias to replace Judas (Acts 1:13-26), and he received the first converts (Acts 2:41). He inflicted the first punishment (Acts 5:1-11), and excommunicated the first heretic (Acts 8:18-23). He led the first council in Jerusalem (Acts 15), and announced the first dogmatic decision (Acts 15:7-11). It was to Peter that the revelation came that Gentiles were to be baptized and accepted as Christians (Acts 10:46-48).
Peter’s preeminent position among the apostles was symbolized at the very beginning of his relationship with Christ. At their first meeting, Christ told Simon that his name would thereafter be Peter, which translates as "Rock" (John 1:42). The startling thing was that—aside from the single time that Abraham is called a "rock" (Hebrew: Tsur; Aramaic: Kepha) in Isaiah 51:1-2—in the Old Testament only God was called a rock. The word rock was not used as a proper name in the ancient world. If you were to turn to a companion and say, "From now on your name is Asparagus," people would wonder: Why Asparagus? What is the meaning of it? What does it signify? Indeed, why call Simon the fisherman "Rock"? Christ was not given to meaningless gestures, and neither were the Jews as a whole when it came to names. Giving a new name meant that the status of the person was changed, as when Abram’s name was changed to Abraham (Gen.17:5), Jacob’s to Israel (Gen. 32:28), Eliakim’s to Joakim (2 Kgs. 23:34), or the names of the four Hebrew youths—Daniel, Hananiah, Mishael, and Azariah to Belteshazzar, Shadrach, Meshach, and Abednego (Dan. 1:6-7). But no Jew had ever been called "Rock." The Jews would give other names taken from nature, such as Deborah ("bee," Gen. 35:8), and Rachel ("ewe," Gen. 29:16), but never "Rock." In the New Testament James and John were nicknamed Boanerges, meaning "Sons of Thunder," by Christ, but that was never regularly used in place of their original names, and it certainly was not given as a new name. But in the case of Simon-bar-Jonah, his new name Kephas (Greek: Petros) definitely replaced the old.
Now, let's expound on Cobra's statement: "He would found His Church on Peter's confession that Jesus was the Son of God".
Not only was there significance in Simon being given a new and unusual name, but the place where Jesus solemnly conferred it upon Peter was also important. It happened when "Jesus came into the district of Caesarea Philippi" (Matt. 16:13), a city that Philip the Tetrarch built and named in honor of Caesar Augustus, who had died in A.D. 14. The city lay near cascades in the Jordan River and near a gigantic wall of rock, a wall about 200 feet high and 500 feet long, which is part of the southern foothills of Mount Hermon. The city no longer exists, but its ruins are near the small Arab town of Banias; and at the base of the rock wall may be found what is left of one of the springs that fed the Jordan. It was here that Jesus pointed to Simon and said, "You are Peter" (Matt. 16:18).
When he first saw Simon, "Jesus looked at him, and said, ‘So you are Simon the son of John? You shall be called Cephas (which means Peter)’" (John 1:42). The word Cephas is merely the transliteration of the Aramaic Kepha into Greek. Later, after Peter and the other disciples had been with Christ for some time, they went to Caesarea Philippi, where Peter made his profession of faith: "You are the Christ, the Son of the living God" (Matt. 16:16). Jesus told him that this truth was specially revealed to him, and then he solemnly reiterated: "And I tell you, you are Peter" (Matt. 16:18). To this was added the promise that the Church would be founded, in some way, on Peter (Matt. 16:18).
Then two important things were told the apostle. "Whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven" (Matt. 16:19). Here Peter was singled out for the authority that provides for the forgiveness of sins and the making of disciplinary rules. Later the apostles as a whole would be given similar power [Matt.18:18], but here Peter received it in a special sense.
Peter alone was promised something else also: "I will give you the keys of the kingdom of heaven" (Matt. 16:19). In ancient times, keys were the hallmark of authority. A walled city might have one great gate; and that gate had one great lock, worked by one great key. To be given the key to the city—an honor that exists even today, though its import is lost—meant to be given free access to and authority over the city. The city to which Peter was given the keys was the heavenly city itself. This symbolism for authority is used elsewhere in the Bible (Is. 22:22, Rev. 1:18).
Finally, after the resurrection, Jesus appeared to his disciples and asked Peter three times, "Do you love me?" (John 21:15-17). In repentance for his threefold denial, Peter gave a threefold affirmation of love. Then Christ, the Good Shepherd (John 10:11, 14), gave Peter the authority he earlier had promised: "Feed my sheep" (John 21:17). This specifically included the other apostles, since Jesus asked Peter, "Do you love me more than these?" (John 21:15), the word "these" referring to the other apostles who were present (John 21:2). Thus was completed the prediction made just before Jesus and his followers went for the last time to the Mount of Olives.
Immediately before his denials were predicted, Peter was told, "Simon, Simon, behold, Satan demanded to have you, that he might sift you like wheat, but I have prayed for you that your faith may not fail; and when you have turned again [after the denials], strengthen your brethren" (Luke 22:31-32). It was Peter who Christ prayed would have faith that would not fail and that would be a guide for the others; and his prayer, being perfectly efficacious, was sure to be fulfilled.
Now take a closer look at the key verse: "You are Peter, and on this rock I will build my Church" (Matt. 16:18). Disputes about this passage have always been related to the meaning of the term "rock." To whom, or to what, does it refer? Since Simon’s new name of Peter itself means rock, the sentence could be rewritten as: "You are Rock and upon this rock I will build my Church."
From the grammatical point of view, the phrase "this rock" must relate back to the closest noun. Peter’s profession of faith ("You are the Christ, the Son of the living God") is two verses earlier, while his name, a proper noun, is in the immediately preceding clause.
As an analogy, consider this artificial sentence: "I have a car and a truck, and it is blue." Which is blue? The truck, because that is the noun closest to the pronoun "it." This is all the more clear if the reference to the car is two sentences earlier, as the reference to Peter’s profession is two sentences earlier than the term rock.
