The Latin Church (Latin: Ecclesia Latina), also known as the Roman Catholic Church (Latin: Ecclesia Catholica Romana) or the Western Church (Latin: Ecclesia Occidentalis), is the largest particular church sui iuris of the Catholic Church, and traditionally employs in the majority the Latin liturgical rites, which since the mid-twentieth century are very often in practice translated into the vernacular. The "Latin Church" is one of 24 such Churches, the 23 others being referred to as a group as the Eastern Catholic Churches. The "Latin Church" is headed by the Bishop of Rome, the Pope—one of whose traditional titles in some eras and contexts has also been the Patriarch of the West, and whose cathedra as a bishop is located in the Archbasilica of Saint John Lateran in Rome, Italy.
