The Coptic Catholic Patriarchate of Alexandria is the Patriarchal and only Metropolitan see of the head of the Eastern sui iuris Coptic Catholic Church, a particular Church in the Catholic Church in full communion with the Holy See, which follows the Alexandrian Rite in its own Coptic language. He is thus the superior of all Coptic dioceses, mostly in and around Egypt (where all its sees are), the word Copt(ic) being a corruption of the Greek word for Egypt(ian).
