The 1979 Book of Common Prayer is the official primary liturgical book of the U.S.-based Episcopal Church. An edition in the same tradition as other versions of the Book of Common Prayer used by the churches within the Anglican Communion and Anglicanism generally, it contains both the forms of the Eucharistic liturgy and the Daily Office, as well as additional public liturgies and personal devotions. It is the fourth major revision of the Book of Common Prayer adopted by the Episcopal Church, and succeeded the 1928 edition. The 1979 Book of Common Prayer has been translated into multiple languages and is considered a representative production of the 20th-century Liturgical Movement.
