“Whoever believes on Him will not be put to shame.
“believes in HIM” i.e. His TEACHING. For this purpose Christ established ONE Church and commanded Peter and his successors to “Go forth and TEACH...”
Presumably this is to TEACH ONE Truth.
Not every Tom, Dick, and Harry gets to crack open the pages of the Bible and authoritatively interpret scripture. That authoritative interpretation was directed specifically to Peter and his successors. When Christ said “Feed my lambs, feed my sheep..,” it was directed specifically to Peter in the presence of the other apostles.
The direction was not to all. Peter was the new head of the Church established by Christ. The successors to Peter form an unbroken line of authority. This is why the canonical texts we use today were officially the identical texts ratified in manner, form, and selection by the Synod of Rome in AD 382. What greater authority than poring over hundreds of written manuscripts and fragments, including some, and discarding others, and then pronouncing that what the Catholic Church deemed authentic inspired by the Holy Spirit as the true word of God.
This authority did not fly out of the window at some late point in time. No one gets to authoritatively interpret the Word of God except the Catholic Church, and its rituals, liturgies, and forms of worship of veneration. The authority was absolute. “WHATSOEVER, thou shall bind on earth shall be bound in heaven...”
Acts 15:8 And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us; 9 And put no difference between us and them, purifying their hearts by faith.
Stop with the nicolaitan cast system already.
Ummm ... you stick with the Catholic Church and I’ll stick with Jesus and the Bible ... :-) ...
