Historically, different breviaries were used in the various parts of Christendom, such as the Aberdeen 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.
