Excommunication

Excommunication is a formal action used by some religious organizations. It means that a person is removed from full participation in a religious community. The word comes from Latin and means "out of communion," with communion meaning shared religious life. Excommunication does not always mean a person is completely rejected. In many traditions, it is meant to mark a break in membership or privileges.

Excommunication is most commonly associated with Christianity. In early Christian communities, it was used to deal with serious disagreements or actions that went against church rules. Church leaders believed that clear boundaries were needed to keep order. Over time, formal rules were created to explain when and how excommunication could happen.

In the Roman Catholic Church, excommunication is defined in church law. Certain actions can lead to it, such as refusing church authority or committing serious offenses under church rules. A person who is excommunicated may not receive sacraments, which are religious ceremonies like communion. The person is still considered baptized but is separated from full church life.

Other Christian groups have similar but different practices. In the Eastern Orthodox Church, a form of exclusion may prevent a person from receiving communion. Some Protestant churches may remove a person from church membership instead of using the term excommunication. Each group decides its own rules, and the effects depend on the church involved.

Excommunication has also played a role in history. During the Middle Ages, church leaders sometimes excommunicated rulers or officials. For example, Holy Roman Emperor Henry IV was excommunicated by Pope Gregory VII in the 11th century during a dispute over authority. Such actions could affect politics because religion and government were closely connected.

In many traditions, excommunication can be lifted. This usually happens when the person and the religious authority reach agreement. The process and requirements vary by religion. Today, excommunication is less common than in the past, but it remains part of religious law and history in several faiths.
