The term "Ukrainian Catholic" refers to members of the Ukrainian Greek Catholic Church, which is an Eastern Catholic Church in communion with the Pope and the wider Roman Catholic Church. This church follows the Byzantine rite, incorporating unique traditions and practices that reflect Ukrainian culture and spirituality. Ukrainian Catholics primarily reside in Ukraine and among the Ukrainian diaspora worldwide. They celebrate the Divine Liturgy, which is similar to the Mass in the Roman Catholic tradition, but features distinct rituals, music, and liturgical language, often using Ukrainian or Church Slavonic.
