A denomination is a large, organised religion that is not officially linked with the state or government, operating independently and typically accepting the existence of other religious groups within a pluralistic society. Unlike a state church, which is officially endorsed and supported by the government, a denomination maintains its own governance and financial autonomy. While denominations may have a significant presence and influence within a society, they do not hold a position of exclusive authority or official recognition by the state. They generally have a well-established history, a large membership base, and a formal organisational structure with defined doctrines and practices. The concept of denomination is particularly relevant in countries with a separation of church and state and a diverse religious landscape, such as the United States, where numerous Christian denominations, as well as other major religions, operate freely.
