Catholic particular churches and liturgical ritesA particular church (ecclesia particularis) is an ecclesiastical community of faithful 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. Thus "particular church" refers to an institution, and "liturgical rite" to its ritual practices.
Western SchismThe Western Schism, also known as the Papal Schism, the Great Occidental Schism, or the Schism of 1378 (Magnum schisma occidentale, Ecclesiae occidentalis schisma), was a split within the Catholic Church lasting from 1378 to 1417 in which bishops residing in Rome and Avignon both claimed to be the true pope, and were joined by a third line of Pisan claimants in 1409. The schism was driven by personalities and political allegiances, with the Avignon papacy being closely associated with the French monarchy.
Cardinal (Catholic Church)A cardinal (Sanctae Romanae Ecclesiae cardinalis, cardinal of the Holy Roman Church) is a senior member of the clergy of the Catholic Church. Cardinals are created by the pope and typically hold the title for life. Collectively, they constitute the College of Cardinals. The most solemn responsibility of the cardinals is to elect a new pope in a conclave, almost always from among themselves (with a few historical exceptions), when the Holy See is vacant.
Vatican CityVatican City (ˈvætᵻkən), officially Vatican City State (Stato della Città del Vaticano; Status Civitatis Vaticanæ), is a landlocked independent country, city-state, microstate, and enclave within Rome, Italy. It became independent from Italy in 1929 with the Lateran Treaty, and it is a distinct territory under "full ownership, exclusive dominion, and sovereign authority and jurisdiction" of the Holy See, itself a sovereign entity under international law, which maintains the city state's temporal power and governance, diplomatic, and spiritual independence.
