Church history, the decisions of church councils, and the decrees of popes do not enter into this discussion. The Bible must give us the answer.”
Right. After all, “if we’re asking a historical question, we should really ignore all the historical sources, and instead, focus on a book whose goal isn’t history as such (but rather, bringing people to faith in Christ). Yeah…
that’s the sole source we should reference!”
peter not presiding counsil of jerusalem
Who was the apostle at the head of the Church of Jerusalem? (Hint: it wasn’t Peter.

)
A modern analogue might be when the POTUS steps into a local courtroom. Does he tell the presiding judge to step aside? Does he stride up to the bench, take the gavel, and pronounce judgment? Of course not!
But… if he stands up to offer testimony, wouldn’t the assembled court hear him and greatly value his testimony? That’s exactly what happens in this passage – after Peter speaks, debate is over. And James, who
is the presiding bishop, passes judgement.
it must be proven that Christ intended that this particular office was first given to Peter and to him alone
Read Mt 16 in the original Greek. When Jesus says “you”, it’s in the singular. He’s talking to Peter. Then read Mt 18. In
that grant of authority, he says “you” in the plural. He’s talking to all the apostles. The difference? Peter is the only one given “the keys to the kingdom” and is the one rock “on whom I will build my church.”
In addition, Peter must have died in the office of the Bishop of Rome
Not a necessary set of assumptions here. They’re making it up as they go along.
All of these things must be proven by the Scripture for the doctrine of the papacy to be accepted.
Wrong. “Proven”? Sure. “Proven by the Scripture”? Why
that particular standard? They haven’t established why it must be in Scripture. (That’s kinda like saying “You say that you’ve baked the the most excellent chocolate cake in the world. Therefore, you must find the recipe in Scripture, or else it’s not what you say it is.”)
The author claims Jesus never mentions Peter’s pre-eminence. That’s not true. See Luke 22:31-32. Jesus is speaking to Peter alone (again, singular “you” when He tells Peter that he will have faith and he will strengthen the apostles).
The author points out Galatians. He fails to mention that Paul’s claim to authentic apostleship is bolstered by his visit
to Peter alone for two weeks.
The author claims “we find no evidence of the papacy in the Bible”. That’s a straw man argument: they’re the ones who claimed that you must find it there, but haven’t demonstrated that their claim is reasonable. It’s like saying “I don’t believe that vanilla ice cream exists; and if it does, you must find it right
here.” (And someone else says, “umm… you’re in the produce aisle, dude. It’s right over there in the freezer, man…”)
Anyway, their claims are arbitrary and weak, IMHO.
