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. A work, then, done by an individual or a group was a liturgy on behalf of the larger 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.
