Christ stated that the Church, NOT Scripture should be the final authority: "And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican." (Matthew 18:17) Christ did NOT state to refer to or consult Scripture for disputes and correction. He said to go to the Church as It is the final authority in Christianity. In addition, St. Paul states that the Church, NOT Scripture is "THE pillar and ground of the truth." (1 Timothy 3:15) Since the Church alone is mentioned as THE pillar of truth, then It alone has the right to discern the truth and interpret Scripture. For if individuals could correctly interpret Scripture, then all interpretations would be EXACTLY THE SAME as there can only be ONE spiritual truth for the plural of the word "truth" NEVER appears in Scripture. The Church is Christ's bride (Ephesians 5:29) and has no spot, wrinkle or blemish (Ephesians 5:27). Christ also stated that the gates of hell will not prevail against His Church (Matthew 16:18).
No instead the catholic church wasn't formed until the rule of Constantine
Scripture clearly points out St. Peter as Christ's representative on earth. Christ did not ask the other Eleven to feed and tend His sheep. If you read The Acts Of The Apostles, it is clear that St. Peter leads the Apostles. Therefore, since the Apostles are to be replaced as they die (Acts 1:20-26), then it follows that whoever succeed(s) St. Peter is leader of the Church. There is only to be one shepherd of the Church (John 10:16). For the Apostles did not argue amongst themselves whether there was a "greatest" at all, but who amongst them was THE greatest (Mark 9:34; Luke 9:46).
Acts 15, The Jerusalem Council. The question of the circumcision party spoken of in Galatians 2:11-13 is the central theme. In verse 7, after much discussion by the elders and Apostles, Peter gets up to speak. In verse 12 Barnabas and Paul have the platform. In verse 13 James begins to speak and we will not hear again of Peter in the Book of Acts.
This James, now speaking, is the brother of the flesh of Jesus Christ.....his half brother (Galatians 1:19). He is not an Apostle. The Apostle James was killed earlier by Herod in Chapter 12. This man, James, is in charge....not Peter. Notice in verse 19...."It is my judgment therefore....." The Jerusalem Church was led, not by Peter, not by Paul, but by James.
