A Catholic Bishop is a senior member of the clergy in the Roman Catholic Church who oversees a specific geographical area known as a diocese. Bishops are responsible for teaching, governing, and sanctifying the faithful within their jurisdiction. They have the authority to ordain priests and deacons, administer sacraments, and ensure that church teachings are upheld. Bishops are part of the hierarchical structure of the Church, which includes the Pope at the top, followed by cardinals, bishops, priests, and deacons. They often participate in regional and global meetings, such as Ecumenical Councils, to discuss important issues facing the Church and its followers.
