Apostolical See
From BiblePortal Wikipedia
Apostolical See [1]
This term, under the full form of "holy apostolical see," is now used to designate the jurisdiction and power of the pope as bishop of Rome. But anciently every bishop's see was dignified with the title of sedes apostolica, (See Apostolical), as deriving its authority through its succession from the apostles (See Apostolical Succession). Pope Siricius himself (Siric. Ephesians 4 , c. 1) gives all primates the appellation Apostolici. St. Augustine, Sidonius Apollinaris, and others make no distinction in favor of the bishop of Rome. See Bingham, Antiq. Of The Christ. Church, p. 22, 67 .
