A liturgy is the customary public worship done by a specific religious group, according to its particular traditions. The word, which especially among Protestants is sometimes rendered by its English translation "service", may refer to an elaborate formal ritual such as the Eastern Orthodox Divine Liturgy and Catholic Mass, or a daily activity such as the Muslim salat and Jewish services. As a religious phenomenon, liturgy is a communal response to the sacred through activity reflecting praise, thanksgiving, supplication, or repentance. Ritualization may be associated with life events such as birth, coming of age, marriage, and death. It thus forms the basis for establishing a relationship with a divine agency, as well as with other participants in the liturgy.
