Pope St. Martin I

“...correct things which are wanting, and appoint Bishops, Presbyters, and Deacons in every city of those which are subject to the See both of Jerusalem and of Antioch; we charging you to do this in every way, in virtue of the Apostolic authority (auctoritate) which was given us by the Lord in the person of most blessed Peter, prince of the Apostles; on account of the necessities of our time, and the pressure of the nations” (Letter to Bishop John of Philadelphia. The Pope is exercising the power of higher jurisdiction over local affairs in Antioch and Jerusalem by acting through this Eastern bishop. The cause was the ordination of heretics in the East. Mansi X. 806).
