An episcopal polity is a hierarchical form of church governance in which the chief local authorities are called bishops.

The Eastern Orthodox Church, also called the Orthodox Church, Greek Orthodox Church, or officially the Orthodox Catholic Church, is the second-largest Christian church, with approximately 220 million baptised members. It operates as a communion of autocephalous churches, each governed by its bishops via local synods. The church has no central doctrinal or governmental authority analogous to the head of the Catholic Church—the pope, although the Ecumenical Patriarch of Constantinople is recognised by them as primus inter pares, a title formerly given to the patriarch of Rome. As one of the oldest surviving religious institutions in the world, the Eastern Orthodox Church has played a prominent role in the history and culture of Western Asia, the Caucasus, and Eastern and Southeastern Europe.

Closed communion is the practice of restricting the serving of the elements of Holy Communion to those who are members in good standing of a particular church, denomination, sect, or congregation.

This restriction is based on various parameters, one of which is baptism. See also intercommunion.
