excommunication

n. exclusion from the rites of the church, banishment, expulsion

Excommunication is a religious censure used to deprive or suspend membership in a religious community. The word literally means out of communion, or no longer in communion. In some churches, excommunication includes spiritual condemnation of the member or group. Censures and sanctions sometimes follow excommunication; these include banishment, shunning, and shaming, depending on the group's religion or religious community. This article addresses excommunication and spiritual condemnation often associated with excommunication, but not the religious censures and sanctions that follow excommunication.
