AGENDA, among Ecclesiastical Writers denotes the service or office of the church. We meet with agenda mutina et respertina, 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, acolouthia, missal, formulary, directory, &c.
