The
common or
common of saints (Latin:
commune sanctorum) is a part of the
Christian liturgy that consists of texts common to an entire category of saints, such as
apostles or
martyrs. The term is used in contrast to the
ordinary, which is that part of the liturgy that is reasonably constant, or at least selected without regard to date, and to the
proper, which is the part of the liturgy that varies according to the date, either representing an observance within the
liturgical year, or of a particular
saint or significant event.
