Evangelisch-Lutherische Gebetsbruderschaft (Evangelical Lutheran Prayer Brotherhood) is a German Lutheran religious society for men and women, based on the doctrines of the Bible and Book of Concord, with regular prayer for the renewal and unity of the Church.
Prayer Brotherhood was founded in Leipzig by Lutheran theological students. The main objectives in the beginning were Augsburg Confession, regular Eucharist on Sundays, and the daily office with mutual prayer.
A breviary (Latin: breviarium) is a liturgical book used in Christianity for praying the canonical hours, usually recited at seven fixed prayer times.
Historically, different breviaries were used in the various parts of Christendom, such as Aberdeen Breviary, Belleville Breviary, Stowe Breviary and Isabella Breviary, although eventually the Roman Breviary became the standard within the Roman Catholic Church (though it was later supplanted with the Liturgy of the Hours); in other Christian denominations such as the Lutheran Churches, different breviaries continue to be used, such as The Brotherhood Prayer Book.
