 Excommunication is the official expulsion of a person from the Catholic faith. The person is informed that they are no longer acting according to the faith, and that they will not be allowed to receive the sacraments any longer. An excommunicated person may attend church, but would not be allowed to take the Eucharist (the bread and the wine). Excommunication is not a permanent punishment; if the person repents and reaffirms their faith then they will be allowed to receive the sacraments again.
