Catholic particular churches and liturgical rites
A particular church (Latin: ecclesia particularis) is an ecclesiastical community of followers headed by a bishop (or equivalent), as defined by Catholic canon law and ecclesiology. A liturgical rite, a collection of liturgies descending from shared historic or regional context, depends on the particular church the bishop (or equivalent) belongs to.
