Definition
A "Greek Catholic" (also called "Byzantine Catholic" or "Eastern Catholic") refers to a group of Eastern Christian Churches in full communion with the Pope in Rome, while maintaining their distinct liturgical traditions, theology, and cultural heritage. They use the Byzantine Rite in their worship, which includes icons, chanting, and unique rituals. They recognize the Pope as the head of the Church but retain Eastern practices such as married priests in some regions. They bridge Eastern and Western Christian traditions.
