diözézis

A diözézis, also commonly spelled diocese, is a geographical area within a Christian church, particularly in Catholicism, Eastern Orthodoxy, and Anglicanism, over which a bishop exercises spiritual and administrative authority. The term originates from the Greek word "dioikēsis," meaning "administration" or "district." A diocese is typically centered around a cathedral, which serves as the bishop's principal church and the seat of his authority.

The bishop's role within a diocese is to teach, sanctify, and govern the faithful. This includes ordaining clergy, administering sacraments, overseeing parishes, and ensuring the doctrinal and moral integrity of the community. The size and population of a diocese can vary significantly, depending on historical development, demographic distribution, and the specific needs of the church. Larger dioceses may be further subdivided into smaller administrative units like vicariates or deaneries, each overseen by a vicar or dean, who acts as a subordinate to the bishop.

The establishment and boundaries of a diocese are determined by the hierarchical structure of the particular church. In some cases, dioceses may be created or altered based on population growth, missionary efforts, or administrative efficiency. The tithe or financial contributions from the faithful within a diocese are often used to support its operations, clergy, and charitable activities. The concept of the diocese is fundamental to the organizational structure and pastoral care provided by these Christian denominations.
