On the one hand, liturgy often means the whole complex of official services, all the rites, ceremonies, prayers, and sacraments of the Church, as opposed to private devotions. In this sense we speak of the arrangement of all these services in certain set forms (including the canonical hours, administration of sacraments, etc.), used officially by any local church, as the liturgy of such a church — the Liturgy of Antioch, the Roman Liturgy, and so on. So liturgy means rite; we speak indifferently of the Byzantine Rite or the Byzantine Liturgy. In the same sense we distinguish the official services from others by calling them liturgical; those services are liturgical which are contained in any of the official books (see LITURGICAL BOOKS) of a rite. In the Roman Church, for instance, Compline is a liturgical service, the Rosary is not.
