a book of devotion, of prayer. That of the Church of England contains the Book of Common Prayer, Administration of the Sacraments, and other rites and ceremonies of the Church. (See COMMON PRAYER).
The service books of the Latin Church include the Missal, the Pontifical, the Day Hours, the Breviary, the Ritual, the Processional, the Ceremonial for Bishops, the Benedictional.
Those of the Greek Church are, (1) the Euchologion, corresponding to the Missal; (2) the Menoea, answering to the Breviary, without the ferial offices, and full of ecclesiastical poetry in measured prose; (3) Paracletice, or great Octoechus, the ferial office for eight weeks, mainly the work of Joseph of the Studium; (4) Triodion, the Lent volume, from the Sunday before Septuagesima to Easter; and (5) the Pentecostarion, the office for Eastertide.
