AGENDA, among ecclesiastical writers, denotes the service or office of the church. We meet with agenda matutina et vespertina, the morning and evening prayers; agenda diei, the office of the day, whether feast or fast; agenda mortuorum, called also simply agenda, the service of the dead.
AGENDA is also applied to certain church-books, compiled by public authority, prescribing the order and manner to be observed by the ministers and people in the principal ceremonies and devotions of the church; in which sense agenda amounts to the same with what is otherwise called ritual, liturgy, acalouthia, missal, formulary, directory, &c.
