A "cathedra" is a special chair or throne used by a bishop in a cathedral, symbolizing his authority and leadership within the Christian community. It is often ornately designed and placed in a prominent location, such as the chancel or sanctuary, to signify its importance. The term "cathedra" also refers to the church itself, known as a cathedral, where the bishop's seat is located. Cathedrals are significant places of worship and often serve as the central church for a diocese, hosting important ceremonies and events within the Christian faith.
