“Nowhere in the early Church system Christ set up was there room for any personal interpretation. It was the Apostles’ way, Peter’s way, Rome’s way— or the highway.”
Golly. Don’t know why Jesus promised the Holy Spirit would teach us, or where the Holy Spirit has any role at all. Why would the Holy Spirit bother with us, when the Vicar of Christ is ruling?
Frankly, the idea that Jesus set up Rome uber alles is ridiculous. The idea that he set up Peter as the Greatest Apostle, ruling all others is contradicted in scripture, in multiple places.
He said it because the Holy Spirit WAS guiding Peter. He sent the Holy Spirit to guide Peter and the Church. No personal interpretation is needed. Peter, and the successive Popes, when speaking on matters of faith, “channel” the Holy Spirit. The Pope is a conduit.
