This kind of shallow street theology reading for which BIble Christians are so well known won’t help. For thousands of year real theologians both Catholic, and Protestant and Jewish theologians who converted to Catholicism have confirmed Petrine authority. These are enough books on the subject to fill libraries of theological departments.
It is this command to go out to the whole world (all nations) that marks the Church that Christ established, which is why that Church came to be known as “Catholic”, from the Greek word katholikos (kata “about”, and holos, “whole”). In the year 110 A.D., not even fifteen years after the book of Revelation was written, while on his way to execution St. Ignatius of Antioch wrote: “Where the bishop is present, there let the congregation gather, just as where Jesus Christ is, there is the Catholic church”. The Church believes that when the bishops speak as teachers, Christ speaks; for he said to them: “He who hears you, hears me; and he who rejects you, rejects me” (Lk 10, 16).
St. Paul in his letters also warns the faithful to hold fast to the tradition they received: “We command you, brothers, in the name of the Lord Jesus Christ, to avoid any brother who wanders from the straight path and does not follow the tradition you received from us” (2 Th 3, 6).
I knew that somebody could look it up.
