Ruthenian Catholic Church

The Ruthenian Catholic Church is a sui iuris (i.e., self-governing) Catholic Church (see particular Church), which uses the Divine Liturgy of the Constantinopolitan Byzantine Eastern Rite. Its roots are among the Rusyns who lived in the region called Carpathian Ruthenia, in and around the Carpathian Mountains. This is the area where the borders of present-day Hungary, Slovakia and Ukraine meet.
