Proper Territory of a Patriarchal Church

CCEO canon 146 defines the territory through both ecclesial patrimony and legitimately acquired governing competence. It is not simply every country where members of the Church now live, the political homeland of an ethnic group, or the sum of places in which its liturgy has ever been celebrated.^[1]

Only the Roman Pontiff authentically resolves doubt about boundaries or decrees their alteration after the synodal investigation and petition required by the code. Maps produced by scholars, national borders, and community custom can describe the situation but cannot themselves enlarge patriarchal competence.

Patriarchs retain solicitude for their faithful abroad and may gather information through a patriarchal visitor with Apostolic See assent. They can propose suitable pastoral structures, but the erection of eparchies or exarchates outside the proper territory and the appointment of bishops there involve the Roman Pontiff according to the code.

Bishops outside the territory participate in the synod with the rights and obligations stated by canon 150. Synodal liturgical laws can have broader force, while disciplinary laws ordinarily bind within the proper territory unless adopted or approved under the conditions provided by the code.

The boundary determines competence for erection, election, legislation, and administration; it does not measure a Church's catholicity or dignity. A Church can have millions of faithful abroad without turning every diaspora country into part of its proper territory.

Church-wide membership, proper territory, diaspora jurisdictions, and civil nations are distinct facts of a patriarchate. Treating those four as one produces false claims about which synod elects a bishop, which law binds, or whether a patriarch can unilaterally erect a jurisdiction abroad.
