By way of liturgical variety, the service of initium noctis may also be studied in the Celtic Liturgy, such as it is read in the Antiphonary of Bangor, its plan being set forth by Warren and by Bishop (see Bibliography, below).
In the breviary of 1974 Roman Catholic Liturgy of the Hours, Compline is divided as follows: introduction, an optional examination of conscience or penitential rite, a hymn, psalmody with accompanying antiphons, scriptural reading, the responsory, the Canticle of Simeon, concluding prayer, and benediction.
