In those Eastern Catholic Churches that are headed by a patriarch, metropolitans in charge of ecclesiastical provinces hold a position similar to that of metropolitans in the Latin Church. Among the differences is that Eastern Catholic metropolitans within the territory of the patriarchate are to be ordained and enthroned by the patriarch, who may also ordain and enthrone metropolitans of sees outside that territory that are part of his Church. Similarly, a metropolitan has the right to ordain and enthrone the bishops of his province. The metropolitan is to be commemorated in the liturgies celebrated within his province.
