The Albanian Byzantine CatholicChurch is an autonomous Byzantine Rite particular Church of the CatholicChurch, whose members lives in Albania, and is not to be confused with the Italo-Albanian CatholicChurch.
Though the Greek liturgical rite was used in many of its churches, Albania was part of the patriarchate of Rome until 731, when Byzantine Emperor Leo III, in reprisal for the opposition of Pope Saint Gregory III to the emperor's iconoclast policy, attached the whole of eastern Illyricum to the patriarchate of Constantinople.
Catholics, of Latin Rite, were long established in the north of the country.
The Eastern CatholicChurches are in full communion of faith and of acceptance of authority with the see of Rome, but retain their distinctive liturgical rites, laws and customs, and traditional devotions.
