Roman Catholicism celebrates its theology and Sacred Tradition by following a prescribed pattern of seasons and individual feasts throughout a yearlong cycle. Known as the liturgical year, these seasons celebrate the birth; life and ministry; and passion, death, and resurrection of Jesus. Individual feasts, fixed by the normal calendar year, celebrate the lives of saints and remember special Biblical and historical events. Governed by a hierarchy of priorities, the liturgical year organizes Roman Catholic celebrations that seek to unite the church, the people of God, as a community of faith.
