Every episcopal see is seen as holy and the Eastern Orthodox Church constantly applies the adjective "holy" or "sacred" () to all its sees, but "the Holy See" (definite singular) normally means the see of Rome, which is also called "the Apostolic See". While "Apostolic See" can refer to any see founded by any of the Apostles, the term is in this case used to refer to the see of the bishop seen as successor of the chief of the Apostles, Saint Peter.
