In the Roman Catholic Church, a parish (Latin: parochus) is a stable community of the faithful within a Particular Church, whose pastoral care has been entrusted to a parish priest (Latin: pastor), under the authority of the diocesan bishop. It is the lowest ecclesiastical subdivision in the Catholic episcopal polity, and the primary constituent unit of a diocese. In the 1983 Code of Canon Law, parishes are constituted under cc. 515–552, entitled "Parishes, Pastors, and Parochial Vicars."
