Liturgy

The word liturgy comes from a Greek term meaning "public work or work done on behalf of the people." Liturgy always referred to an organized community. All the worshipers are expected to participate actively in each liturgy, for this is holy "work," not entertainment or a spectator event. Every liturgical celebration is an action of Christ the High Priest and of his Mystical Body, which is the Church. It therefore requires the participation of the People of God in the work of God.

The Catechism of the Catholic Church discusses the Liturgy of the Church in Part II, beginning at paragraph 1066.

The Church has many liturgies such as the Liturgy of Baptism, Liturgy of the Hours, etc. The best known liturgy is the central focus of Christian worship, known in the west as Holy Mass and in the east as the Divine Liturgy.
