A Catholic Diocese is a specific geographical area under the pastoral care of a bishop in the Roman Catholic Church. Each diocese consists of multiple parishes, which are local communities of worship. The bishop oversees the spiritual and administrative needs of the diocese, ensuring that the teachings of the Church are upheld. Dioceses vary in size and population, with some serving large urban areas while others cover rural regions. The structure of a diocese includes various ministries and programs aimed at supporting the faith and community life of its members. Each diocese is part of a larger ecclesiastical province, which may include several dioceses under the leadership of an archbishop.
