Diocese
A diocese is a defined territory or community of the faithful entrusted to the pastoral care of a bishop, forming the basic administrative unit of the Catholic Church. Each diocese is further divided into parishes.
The Bishop's Own Church
A diocese is often described as a bishop's own particular church, the concrete local community he is called to teach, sanctify, and govern in communion with the Pope. Dioceses vary enormously in size, from a few thousand Catholics to several million, depending on population and history.
How Dioceses Are Organized
Every diocese is divided into parishes, each usually served by one or more priests under the bishop's authority, and a diocese may also include religious communities, schools, and charitable institutions. An archdiocese is a diocese of particular size or historical importance, led by an archbishop.
Frequently Asked Questions
What is the difference between a diocese and a parish?
A diocese is the larger territory governed by a bishop; a parish is a smaller local community within that diocese, usually centered on a single church, served by a pastor answerable to the bishop.
Can a diocese's boundaries change?
Yes. Diocesan boundaries are set by the Holy See and can be adjusted, merged, or split over time to reflect population shifts or pastoral needs.
