The Ukrainian Greek Catholic Church (UGCC) is a major Eastern Catholic Church that follows the Byzantine rite. It is in full communion with the Roman Catholic Church and recognizes the authority of the Pope. The UGCC primarily serves the Ukrainian community and has a rich history that dates back to the Union of Brest in 1596, which united the Orthodox Church in Ukraine with the Catholic Church. The church plays a significant role in the spiritual and cultural life of Ukrainians, both in Ukraine and in the diaspora. It emphasizes the importance of tradition, liturgy, and community, and is known for its vibrant religious practices and celebrations. The UGCC has faced challenges, especially during periods of political turmoil in Ukraine, but continues to thrive and adapt to modern times.
