A diocese is a district under the pastoral care of a bishop in the Christian church. It serves as an administrative region that encompasses multiple congregations, allowing for organized governance and support of local churches. Each diocese is responsible for the spiritual and administrative needs of its members. Dioceses can vary in size and population, often reflecting the geographical and cultural diversity of the area they serve. In the Roman Catholic Church, for example, a diocese is typically led by a bishop, while in other denominations, such as the Anglican Church, it may be overseen by a bishop or archbishop.
