Eastern Catholic (Byzantine Rite)
Eastern Catholic Churches are a family of 23 self-governing (sui iuris) churches in full communion with the Bishop of Rome while preserving their own Eastern liturgical, theological, and canonical traditions. The Byzantine Rite Eastern Catholics—including the Ukrainian Greek Catholic, Melkite Greek Catholic, and Romanian Greek Catholic churches—represent the largest portion of Eastern Catholics worldwide. They celebrate the Divine Liturgy of St. John Chrysostom and share deep liturgical heritage with Eastern Orthodoxy, while affirming papal primacy and full communion with Rome.
