The use of the terms "pope" was not used until several centuries later, but the label of being the "Bishop of Rome" was used by the end of the 1st century. Matter of fact, Ignatius of Antioch wrote a letter to Clement of Rome that mentions Peter being executed there and that the leadership of that bishop would be necessary to help keep the Church as "one body", which Paul repeatedly insisted must be the case. Without such leadership the Church would fragment, which unfortunately it did centuries later anyway.
That has already ben explained, so you simply have some sort of "issue" trying to negate what's found in the Gospels on this. Paul simply cannot and does not make important decisions on his own as he shown by his actions of consulting with Peter, whereas it's Peter who makes these decisions. And it's also Peter's vision that ended the Jewish law of keeping kosher that opened the door to abandoning the letter of the law so as to carry forth Jesus' Two Commandments that was and is the theological foundation for the Church.
You claim to believe in the Bible and yet you refuse to believe what's in there dealing with this issue, and you're making it increasingly clear why, namely an anti-Catholic bias.
"Rome" didn't make these decisions, but the Church under leadership from the Bishop of Rome and other bishops made them as appointees of the Apostles that one can see happening in Acts.
Maybe do some studying on early Church history, and one can even start here:
