List of people excommunicated by the Catholic Church
|Part of a series on the|
|Canon law of the|
This is a list of some of the more notable people excommunicated by the Catholic Church. It includes only excommunications acknowledged or imposed by a decree of the Pope or a bishop in communion with him. Latae sententiae excommunications, those that automatically affect classes of people (members of certain associations or those who perform actions such as directly violating the seal of confession or carrying out an abortion), are not listed unless confirmed by a bishop or ecclesiastical tribunal with respect to certain individuals.
In Roman Catholic canon law, excommunication is a censure and thus a "medicinal penalty" intended to invite the person to change behavior or attitude that incurred the penalty, repent, and return to full communion. Excommunication severs one from communion with the Church; excommunicated Catholics are forbidden from receiving any sacrament and refused a Catholic burial, but are still bound by canonical obligations such as attending Mass or fasting seasonally. Excommunicated Catholics, however, are barred from receiving the Eucharist or from taking an active part in the liturgy (reading, bringing the offerings, etc.). They are still Catholics per se, but are separated from the Church.
