The Byzantine Rite took shape in Constantinople, drawing on the liturgical heritage of Antioch and the city's great churches. It is followed by the largest family of Eastern Catholic Churches, who use the Divine Liturgies of Saint John Chrysostom and Saint Basil the Great.

The Byzantine Rite is shared by many Eastern Catholic Churches sui iuris, including the Melkite, Ukrainian, Ruthenian, Romanian, and others, all in full communion with the Pope.
