First of all, welcome! It is clear that you have learned critical thinking very well. Protestantism, first and foremost, rejects central Church authority - the authority that you have discerned that Christ gave to Peter. If there is no central authority, what you rely on then is the individual ego interpreting scripture. Aside from the fact that private interpretation of scripture is banned by scripture itself (and, by Peter no less! 2 Peter 1:20), you can easily see why there are countless protestant denominations, all of which disagree with one another over certain things. Rather than denominations, they are men’s egos conflicting - exactly as the reformers did immediately upon splitting form the Church in the 16th century. This itself violates Christ’s prayer that we be one, as He and the Father are one.
As to Catholicism and Orthodoxy, it is much more subtle - and complicated. Yet, both Churches trace, in an unbroken line, directly back to Christ via the Apostles and their successors. However, the point may be becoming increasingly moot, as the two are in constant talks regarding a solution to the great schism. I believe that, one day in the future, they will be re-united. Yet, as a Catholic, I see that the fullest expression of the One Church is the one united behind the successor of Peter. Ever notice that the entire world seems to hate the Catholic Church? We see that there are no anti-Methodost websites, no anti-Presbyterian websites. We could go on and on. But, anti-Catholic websites? Seemingly thousands of men and women are raking in big bucks preaching just how awful the Catholic Church is, and how right they themselves are about everything theological.
As a side note: Each and every protestant denomination uses the bible of 66 books that Martin Luther personally held to be inspired scripture. I note that each and every splinter group, sect and cult uses that same 66 book bible. From the Mormons to the Jehovah’s Witnesses, to the Branch Davidians to Jim Jones - all used the 66 book bible. I wonder if the “reformers”, instead of reforming, actually opened Pandora’s box?
Not a single one of them uses the 73 book Catholic bible. Zero. I find that to be a telling fact.
Here is something interesting to sink your teeth into
In the books of men, the following titles are commonly used with reference to a man: “Pope,” “Holy Father,” “Vicar of Christ,” “Sovereign Pontiff.” All of these are titles that rightly belong only to the Lord Jesus Christ and to God the Father. There is not a single instance in the Scriptures where any of the above titles are applied to a man. The term, “Holy Father” is used only once in the entire Bible, and it is used by Jesus in addressing God the Father. (John 17:11)
Among the above titles is the bold assertion that the Pope is the “Vicar of Christ.” A “vicar” is “One serving as a substitute or agent; one authorized to perform the functions of another in higher office.” (Webster). When one searches the Bible from cover to cover, he finds only one passage which gives an indication of a vicar of Christ or God. It is 2 Thess. 2:3-4; it is worded as follows:
“Let no one deceive you in any way, for the day of the Lord will not come unless the apostasy comes first, and the man of sin is revealed, the son of perdition, who opposes and is exalted above all that is called God, or that is worshiped, so that he sits in the temple of God and gives himself out as if he were God.”
Some religionists today advocate that man is saved by faith only. However, there is only one passage in the entire Bible that has the words “faith” and “only” together and it says, “not by faith only” (James 2:24). The Catholics today speak of the Pope as vicar, taking the place of God (Christ Himself is God, Matt. 1:23; John 1:1), yet there is only one passage in the entire Bible which speaks of a man doing such and it calls him “the man of sin.”
James Cardinal Gibbons, a Catholic Archbishop said, “Jesus our Lord, founded but one Church, which He was pleased to build on Peter. Therefore, any church that does not recognize Peter as its foundation stone is not the Church of Christ, and therefore cannot stand, for it is not the work of God.” (The Faith of Our Fathers, p. 82). The apostle Paul said, “For other foundation no one can lay, but that which has been laid, which is Christ Jesus” (1 Cor. 3:11). There is no other foundation but Christ! Therefore, any church which does not recognize Christ alone as the foundation stone cannot be the church of Christ.
Catholic writers often speak of “the primacy of Peter” and “the primacy of the Pope.” However, Col. 1:18, speaking of Christ, says, “And he is the head of the body, the church, who is the beginning, the first-born from the dead; that in all things he may hold the primacy…” Thus, with reference to the authority in the church, the Lord Jesus Christ holds the primacy in all things. This leaves nothing for the Pope!
Catholics claim that the Pope is the visible head of the church. Please notice the following from Catholic sources:
“The pope, therefore, as vicar of Christ, is the visible head of Christ’s kingdom on earth, the Church, of which Christ Himself is the invisible head.” (Answer Wisely, by Martin J. Scott, p. 49).
“According to the will of Christ, all its members profess the same faith, have the same worship and Sacraments, and are united under the one and same visible head, the Pope.” (Father Smith Instructs Jackson, by John F. Noll and Lester J. Fallon, p. 42)
Catholic officials always use the word “visible” no doubt thinking that it removes the thought of the Pope standing in opposition to the headship of Christ, and removes the apparent problem of having a church with two heads. Nonetheless, the Scriptures nowhere teach the idea of a visible and invisible head. Jesus said, “All authority in heaven and on earth has been given to me.” (Matt. 28:18; Emp. mine D.R.).
Luke 17:20-21 says, “And on being asked by the Pharisees, ‘When is the kingdom of God coming?’ he answered and said to them, The kingdom of God comes unawares. Neither will they say, ‘Behold, here it is,’ or ‘Behold, there it is.’ For behold the kingdom of God is within you.” The kingdom of God is a spiritual kingdom and therefore needs only a spiritual head or king.
Eph. 5:23-25 shows that Christ is the only head of the church. “Let wives be subject to their husbands as to the Lord; because a husband is the head of the wife, just as Christ is head of the Church, being himself savior of the body. But just as the Church is subject to Christ, so also let the wives be to their husbands in all things.” Consequently, the wife is subject to her husband as the church is to Christ. Just as the wife is subject to only one head–her husband, the church is subject to only one head–Christ. Just as the husband does not send a substitute to rule over his wife, Christ does not authorize a substitute to rule over His bride, the church.
Catholics often use the expression, “One fold and one shepherd” to sustain the doctrine of the papacy. (See Catholic Catechism For Adults, p. 59, q. 3). They teach that the “one shepherd” is the Pope and the “one fold” represents the Catholic Church. Hear what Jesus said about it:
“I am the good shepherd. The good shepherd lays down his life for his sheep…I am the good shepherd, and I know mine and mine know me, even as the Father knows me and I know the Father; and I lay down my life for my sheep. And other sheep I have that are not of this fold. Them also I must bring and they shall hear my voice, and there shall be one fold and one shepherd.” (John 10:11, 14-16).
Jesus is that one good shepherd. If one can understand that one and one equals two, he can understand this. If one is subject to Christ as the one shepherd–that’s one. If one is subject to the Pope as the one Shepherd–that’s two!
The church is often compared to the human body in the Scriptures. The members of the church are represented as the various parts of the body. Christ is always said to be the head. (See 1 Cor. 12:12-27; Eph. 1:22-23; 4:15-16). Our question is: “What part of the body is the Pope?” Also, “How does one get the idea of a sub-head into the body?”
One of the greatest arguments against the primacy of Peter is the fact that the apostles had an argument among themselves as to which of them should be the greatest. Notice the following:
“Now there arose a dispute among them, which of them was reputed to be the greatest. But he said to them, ‘The kings of the Gentiles lord it over them, and they who exercise authority over them are called Benefactors. But not so with you. On the contrary, let him who is greatest among you become as the youngest, and him who is chief as the servant.’” (Luke 22:24-26).
The very fact that the apostles had an argument among themselves shows they did not understand that Peter was to be prince. Also, the occasion of the argument was the night of the betrayal–the last night of the Lord’s earthly ministry–and yet the apostles still did not understand that Christ had given Peter a position of primacy. The Lord settled the argument, not by stating that He had already made Peter head, but by declaring that the Gentiles have their heads, “But not so with you.” Thus, Jesus very plainly taught that no one would occupy any such place as a Benefactor (or Pope) to exercise authority over the others.
