The majority of the Eastern Catholic Churches are groups that, at different points in the past, used to belong to the Eastern Orthodox Church, the Oriental Orthodox churches, and the historic Church of the East, but are now in communion with the Bishop of Rome due to political and cultural circumstances. The five liturgical traditions of the twenty-three Eastern Catholic Churches, including the Alexandrian Rite, the Armenian Rite, the Byzantine Rite, the East Syriac Rite, and the West Syriac Rite, are shared with other Eastern Christian churches. Consequently, the Catholic Church consists of six liturgical rites, including the aforementioned five liturgical traditions of the Eastern Catholic Churches along with the Latin liturgical rites of the Latin Church.
