In the Catholic Church, a parish (Latin: parochia) is a stable community of the faithful within a particular church, whose pastoral care has been entrusted to a parish priest (Latin: parochus), 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 or eparchy. Parishes are extant in both the Latin and Eastern Catholic Churches. In the 1983 Code of Canon Law, parishes are constituted under cc. 515–552, entitled "Parishes, Pastors, and Parochial Vicars."
