You say, “1054 was a rough year,” and I have to confess that’s a rather gross understatement for a year where one Holy See (the Roman Church) excommunicated the other four (the Holy Sees of Constantinople, Jerusalem, Alexandria, and Antioch). All of these churches were founded by apostles and evangelists, and yet in 1054 these “apostolic” churches split from one another. EDITED FOR BREVITY
I am remined of a variation of a often quoted verse - “God so loved the world that He did not send a committee…” The basis for answering your question lies in two area: Papal Primacy and Papal Infallability. Here is a link:
ewtn.com/expert/answers/papal_primacy.htm The basis for this lies in Matthew 16:18 when Christ puts Peter in charge of the Church of Christ - the Catholic Church. He did not put a committee in charge, and this is an important consideration. Now, if you think He did, you will need to provide a reference.

“The doctrine of papal primacy upholds the divine authority of the Successor of St. Peter to rule over the entire Church with ordinary and immediate jurisdiction. Two Magisterial texts are key to understanding its supreme nature and the obligation of all who are not invincibly ignorant of this truth to submit to Papal authority for the sake of their salvation.
Pope Boniface VIII, in his Bull Unam Sanctum (1302), spelled out the doctrine of the necessity of the Church for salvation and with it the necessity of submission to the Roman Pontiff. Regarding the primacy of authority of Peter and his successors he stated…”* EDITED FOR BREVITY - GO TO LINK PROVIDED FOR FULL EXPLANATION.
Now, go to John 21:15-23. Here we see the Risen Christ speaking with the Apostle who denied even knowing Jesus - working on his rehabilitation! And, does Christ say something like “Peter, you’re fired!” No. Christ focuses on Peter’s primary role in the Church Christ has founded - to feed both lambs and sheet. Peter is in charge, and simply stated, the other Apostles are NOT in charge of the Church.
Either you believe that God the Father knew what He was doing when He selected Peter and gave him the answer to Christ’s question (Matt 16) or, you don’t. And, yes, this takes faith in the word of God. But, just read what is there. Peter is not just one vote out of total.
In response to this, you jump subjects and declare that the Roman Catholic Church is the true one because God is preaching the gospel throughout the world with it. Well…I could very well look at other churches, most of them Protestant, who are doing likewise. EDITED FOR BREVITY
Well, this too will take faith - but, here goes, Matt 28:19 specifically tells the Apostles to go out into the world and baptize in the name of the Trinity. The role of the Church is to evangelize and witness to all. Yes, others (Protestants) are doing this… and truly this is part of God’s Divine Plan - but, I can not explain what this plan is (effectively, different groups are bearing witness to Christ, yet taking His Words and standing them on their head (Baptism is NOT necessary for salvation, Holy Communion is NOT the Body of Christ, we do NOT go to men to have our sins forgiven, etc.). All I can say is that merely because groups shout, "Lord! Lord! ( Matt 7:21 ) or, cast out devils in the name of Christ ( Matt 7:22 ) does not mean that they will receive a eternal reward of being with God. Personally, I am not satisfied with this answer, so, if anyone wants to lend a hand…consider this an invitation!
Again, however, this jumps from the point that if we’re going to say Christ founded one church through the apostles…what happened when those apostolic churches (again, all the major churches in Asia Minor and Italy were founded, for the most part, by apostles and evangelists) split from one another? I guess what I’m asking for is a consistency in the logic of what we’re using to define the gates of hell prevailing against the church of Christ.
