Churches for which the liturgy is standardized in their worship services - such as the [[Catholic Church]], [[Anglican]], [[Lutheran]], and [[Presbyterian]] Churches - are sometimes called liturgical churches. In some churches, such as those of the [[Roman Catholic]] and [[Eastern Orthodox]] traditions, the liturgy has a more specific meaning, referring to the [[Mass]] or [[Holy Communion]] service. Liturgy is sometimes prescribed according to a book containing the set order of worship for each service, such as the [[Book of Common Prayer]] in the Anglican and Episcopal churches. | Churches for which the liturgy is standardized in their worship services - such as the [[Catholic Church]], [[Anglican]], [[Lutheran]], and [[Presbyterian]] Churches - are sometimes called liturgical churches.
