Basilica of St. John Lateran in the context of "John the Evangelist"

An episcopal polity, also known as episcopalianism, is a hierarchical form of church governance in which the chief local authorities are called bishops. The word "bishop" here is derived via the British Latin and Vulgar Latin term *ebiscopus/*biscopus, from Ancient Greek ἐπίσκοπος (epískopos) 'overseer'. It is the structure used by many of the major Christian Churches and denominations, such as the Catholic, Eastern Orthodox, Oriental Orthodox, Church of the East, Anabaptist, Lutheran, and Anglican churches or denominations, and other churches founded independently from these lineages. Many Methodist denominations have a form of episcopal polity known as connexionalism.

Pierre Le Gros (12 April 1666 Paris – 3 May 1719 Rome) was a French sculptor, active almost exclusively in Baroque Rome where he was the pre-eminent sculptor for nearly two decades.

He created monumental works of sculpture for the Jesuits and the Dominicans and found himself centre stage of the two most prestigious artistic campaigns of his era, the Altar of Saint Ignatius of Loyola in the Gesù and the cycle of the twelve huge Apostle statues in the nave of the Lateran basilica. Le Gros' handling of the marble attracted powerful patrons like the papal treasurer Lorenzo Corsini (much later to become Pope Clement XII) and Cardinal de Bouillon, as Dean of the Sacred College the highest ranking cardinal. He also played a prominent role in more intimate settings like the chapel of the Monte di Pietà and the Cappella Antamori in San Girolamo della Carità, both little treasures of the Roman late baroque not known to many because they are difficult to access.

The Cadaver Synod (also called the Cadaver Trial; Latin: Synodus Horrenda) is the name commonly given to the ecclesiastical trial of Pope Formosus, who had been dead for about nine months, in the Basilica of St. John Lateran in Rome during January 897. The trial was conducted by Pope Stephen VI, the successor to Formosus's successor, Pope Boniface VI. Stephen had Formosus's corpse exhumed and brought to the papal court for judgment. He accused Formosus of perjury, of having acceded to the papacy illegally, and illegally presiding over more than one diocese at the same time. At the end of the trial, Formosus was pronounced guilty, and his papacy retroactively declared null.
