**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.
