A bishop is a high-ranking official in the Christian church, responsible for overseeing a group of local churches, known as a diocese. Bishops play a vital role in guiding their communities, providing spiritual leadership, and ensuring that church teachings are followed. They often perform important ceremonies, such as ordaining new priests and confirming church members. Bishops are typically chosen from among the clergy and are often seen as a bridge between the church and the wider community. They may also be involved in social issues, advocating for justice and support for those in need, reflecting the church's mission to serve humanity.
