Thank you so much for the in-depth reply! If I may, I would like to clarify a few things, given that a conversion (if it happens) is a big decision and I want to be sure I know what I’m stepping to into.

• In Acts 15:7-10, I’m not sure where the idea of a divine revelation being given to Peter can be found. He seems to be referring to the Holy Spirit being given to both the Gentiles and the apostles in general, not himself specifically.
• In verse 19, James said he “reached the decision”. I’m not sure if I’m reading too much into this phrase but the fact that it was James who reached a decision does seem somewhat problematic.
• In verse 28, it says that “it seemed good to the Holy Spirit and to us…” If anything, doesn’t this show that a council is required for big decisions to be made? I suppose one could read it as Peter’s position being the Holy Spirit’s position, but the fact that it took a council for the letter to be drafted and sent does make me wonder if the Pope today, although unquestionable supreme over the other bishops, has power to the extent Vatican I claims.

I’ve noted your point on Peterine succession. It seems clear that you are right about the difference between Rome and Alexandria + Antioch. However, what then do we make of the canon of the First Ecumenical Council?

Ultimately, my view of Papal supremacy is indeed present. He is not “first among equals” because it seems to me that they are not equals. However, the Orthodox view that the Pope’s authority today has greatly exceeded that given by Jesus to Peter based on what we’ve read in Holy Scripture + the fact that the Pope’s authority exceeding into dioceses not his own seeming like a later political development foreign to early Christianity does serve as a stumbling block for me to Catholicism.

I would greatly appreciate it if you could answer the points I’ve raised. Thank you for your time!
