Biblically, Moses and Aaron served together and as equals to 70-Elders of the Church, all anointed under the oil of the Holy Spirit. The 12-Apostles were required by Jesus to go out 2-by-2 to rebuke the other if one should sin against the Word of God; and they established 72-Elders of their equal, who also grew the Church. David served with, not apart from Nathan. Elijah served with Elisha. The Angle of the Lord (Jesus) is seen directly accompanying Abraham. All 12-Apostles equally shared and partook in the Holy Spirit, the responsibility of growing Jesus’ Church. The 1st one true Church of St. Peter was in Antioch (Turkish boarder with Syria), and known as the Center of Christendom for centuries, long before Rome. A pope was assigned to Antioch, Constantinople, Alexandria, and Rome at one point under the Ecumenical Council of Bishops. The Western Catholic Church had three popes at Avignon, Rome, and Constantinople. Not until the conciliarism was abolished in 1517, was it officially doctrinal to restrict the number of popes a Ecumenical Council of Bishops could restrict to only one. The 1st Vatican Council had to make a public ruling that the Pope of 1854 had the authority to declare himself the 1st to have infallibility.
