For God so loved the world he sent a book. That seems to be what you are saying here.
The pillar and foundation of truth is not the Bible. it is the Church.
1 Timothy 3:15
Your assumption that Rome is the "church" is where this thinking goes off the rails. The "assembly" of God is what Paul is writing to Timothy about and this is not a formal organization with a human leader. That is your organization's arrogant assumption. Go read the Greek. It is not what the text says.
And, if the text is not important to guide us, why harken to it to prove your point?
