Greek Orthodox Patriarch of Jerusalem
The monastery, along with several dependencies in the area, constitute the entire Church of Sinai, which is headed by an archbishop, who is also the abbot of the monastery. The exact administrative status of the church within the Eastern Orthodox Church is ambiguous: by some, including the church itself, it is considered autocephalous, by others an autonomous church under the jurisdiction of the Greek Orthodox Church of Jerusalem. The archbishop is traditionally consecrated by the Greek Orthodox Patriarch of Jerusalem; in recent centuries he has usually resided in Cairo. During the period of the Crusades which was marked by bitterness between the Orthodox and Catholic churches, the monastery was patronized by both the Byzantine emperors and the rulers of the Kingdom of Jerusalem, and their respective courts.
