Excommunication is an institutional act of religious censure used to deprive, suspend, or limit membership in a religious community or to restrict certain rights within it, in particular those of being in communion with other members of the congregation, and of receiving the sacraments.
Fanciful 16th-century fresco in the Sala Regia, by Giorgio Vasari, depicting Pope Gregory IX excommunicating Frederick II. Since few details were provided to the artist, Vasari chose to paint an excommunication scene generically. In the traditional excommunication procedure, the pope and his priests would hurl burning candles on the ground and stamp them out. The painter however here chose to show the pope personally stepping on the emperor.
Plaque on exterior of the Chiesa della Pietà in Venice, the church of the orphanage. This is where the foundling wheel once stood. The inscription declares, citing a 12 November 1548 papal bull of Pope Paul III, that God inflicts "maledictions and excommunications" on all who abandon a child of theirs whom they have the means to rear, and that they cannot be absolved unless they first refund all expenses incurred.

A Christian denomination is a distinct religious body within Christianity that comprises all church congregations of the same kind, identifiable by traits such as a name, particular history, organization, leadership, theological doctrine, worship style and, sometimes, a founder. It is a secular and neutral term, generally used to denote any established Christian church. Unlike a cult or sect, a denomination is usually seen as part of the Christian religious mainstream. Most Christian denominations refer to themselves as churches, whereas some newer ones tend to interchangeably use the terms churches, assemblies, fellowships, etc. Divisions between one group and another are defined by authority and doctrine; issues such as the nature of Jesus, the authority of apostolic succession, biblical hermeneutics, theology, ecclesiology, eschatology, and papal primacy may separate one denomination from another. Groups of denominations—often sharing broadly similar beliefs, practices, and historical ties—are sometimes known as "branches of Christianity". These branches differ in many ways, especially through differences in practices and belief.
