Paul was compelled by the Holy Spirit to go to Jerusalem to have the content of his preaching approved by Church leaders (Gal 2:1-2).
Paul is very clear he received the gosple and authority from Christ Himself.
He went up to Jerusalem In Galatians after 14 years of preaching, and founding a few churches at least.
“Then
after fourteen years, I went up again to Jerusalem,” Gal 1:1
Paul also consulted the Church leaders in Jerusalem to settle a doctrinal dispute between he and Barnabus ((Acts 15:2-3).
I would hope so, for it was from the Jerusalem church that leaven, yeast , bad doctrinal application, came from.Go to the source of the problem, and have those leaders reign in error coming from their jurisdiction. For sure the apostles held authority in churches thu out the whole world , and they needed to reinforce correct doctrine
If Paul were alive today, which Church would he go to have his preaching approved and to settle doctrinal disputes?
Paul today would have much castigating to do, perhaps in all churches, not excluding Rome.
No one, no one is denying the church of apostolic times, which was not Roman, Orthodox , nor protestant. Yet several views remain and just how they operated. It is in the eyes of the beholder. Where you sit on a matter is where you also stand. You see head bishop/papacy, being above the other apostles jurisdictionally. Others do not.
Which Church do YOU go to have YOUR doctrines approved?
Many of our doctrines were at one time approved by CC, and by Orthodox, some councils, early fathers, tradition. Of course not all, by all, anymore. Catholicism is not the only “church” that has a magisterium of sorts, whith confessions, creeds, catechisms, even councils.
Paul corrected Peter when his behaviour erred, but would nevertheless have recognized him as the leader of the Church.
Again, it is in eyes of beholder just how that was understood back then. For sure Peter was the leader of the twelve original apostles, and original church.
For sure scripture cites Christ as the chief cornerstone, with the the twelve apostles next as our foundation, all and following disciples, living stones.
So i do not think he needed his doctrine ‘approved" in general sense. He wished to mitigate the tension of "others’’, to pacify them, by adding apostolic seal of approval to his gospel of liberty. Otherwise , he would not compromise any of his gospel with the gentiles. Thankfully the Spirit led him to Jerusalem, as the Spirit also led the church at Jerusalem to be of same accord.
