If Christianity is true, then Catholics are right

According to my opponent, Jesus' words in Matthew 16:18 "infallible, at least when teaching on religious matters." Why does Jesus rebuke Peter just a few verses later, calling him Satan and a hindrance? He tells Peter he isn't setting his mind on the things of God. Why does Paul not distinguish between Peter and James and John in Gal 2? And why does Paul rebuke him? In contrast to the Magisterium structure you want to prop up, Jesus says in Matthew 23:8-10, "But do not be called Rabbi; for One is your Teacher, and you are all brothers. Do not call anyone on earth your father; for One is your father, He who is in heaven. Do not be called leaders; for One is your Leader, that is, Christ." Likewise 1 John 2:27-28 says: As for you, the anointing which you received from Him abides in you, and you have no need for anyone to teach you; but as His anointing teaches you about all things, and is true and is not a lie, and just as it has touch you, you abide in him. Not only this, but Clement of Alexandria said,"For they say that Peter and James and John after the ascension of our Saviour, as if also preferred by our Lord, strove not after honor, but chose James the Just bishop of Jerusalem" (Jerome, On Illustrious Men, 2) So, James, not Peter, was the bishop of Jerusalem. And if there was any church with preeminence, it was Jerusalem. Why was the first pope not the head of the preeminent church? Why was it James, not Peter delivering the ruling in the first counsel? Is Matthew 28:19-20 a command? Does John 20:23 only apply to those present when it was said? That is, did Thomas not receive the power to forgive sins? In Luke 10:16, was Judas among those given "legislative power"? If 1 Corinthians 3:1-10 is about hierarchy, why does verse 10 end with a warning to be careful how you build? And why is it followed by verses about how that work (of building the church) can be built up? Can the church hierarchy fail? If Acts 1:21-26 is about the succession of apostles, why are there only 12 foundation stones mentioned in Revelation 21:14? And, which name is written on the 12th: Matthias or Paul? It is called noble in Acts 17, when the laity held an Apostle to the standard of Scripture rather than taking him at his word. Does this fly in the Roman Catholic church? I wonder why Cyprian didn't mention the pope" Perhaps it is because there was no pope at the time he was writing. I find it more likely that Cyprian was talking about the current state of the Church than paving the way for papists. If the Church is in *all* Bishops, what are we to make of it when a Bishop, rather than the multitude under him, goes astray? If an apostle can go astray, why can't a Bishop? St. Macrina the Younger (330 - 379) wrote: We make the Holy Scriptures the rule and measure of every tenet; we necessarily fix our eyes upon that, and approve that alone which may be made to harmonize with the intention of those writings. (NPNF2, Vol. 5, Gregory of Nyssa, On the Soul and Resurrection) St. Basil (329-379) wrote to a widow: Enjoying as you do the consolation of the Holy Scriptures, you stand in need neither of my assistance nor that of anybody else to help you to comprehend your duty. You have the all-sufficient counsel and guidance of the Holy Spirit to lead you to what is right. (NPNF2, Vol. 8, Basil, Letters, Letter 283) Basil seems to be in accord with the 1 John passage above and seems to be asserting not just the material, but the formal sufficiency of the Bible. I await my opponent's response.
