Excommunication in the context of "Shunning"

The Western world, also known as the West, primarily refers to various nations and states in Western Europe, Northern America, and Australasia; with some debate as to whether those in Eastern Europe and Latin America also constitute the West. The Western world likewise is called the Occident (from Latin occidens 'setting down, sunset, west') in contrast to the Eastern world known as the Orient (from Latin oriens 'origin, sunrise, east'). Definitions of the "Western world" vary according to context and perspectives; the West is an evolving concept made up of cultural, political, and economic synergy among diverse groups of people, and not a rigid region with fixed borders and members.

Some historians contend that a linear development of the West can be traced from Ancient Greece and Rome, while others argue that such a projection constructs a false genealogy. A geographical concept of the West started to take shape in the 4th century CE when Constantine, the first Christian Roman emperor, divided the Roman Empire between the Greek East and Latin West. The East Roman Empire, later called the Byzantine Empire, continued for a millennium, while the West Roman Empire lasted for only about a century and a half. Significant theological and ecclesiastical differences led Western Europeans to consider the Christians in the Byzantine Empire as heretics. In 1054 CE, when the church in Rome excommunicated the patriarch of Byzantium, the politico-religious division between the Western church and Eastern church culminated in the Great Schism or the East–West Schism. Even though friendly relations continued between the two parts of Christendom for some time, the crusades made the schism definitive with hostility. The West during these crusades tried to capture trade routes to the East and failed, it instead discovered the Americas. In the aftermath of the European colonization of the Americas, primarily involving Western European powers, an idea of the "Western" world, as an inheritor of Latin Christendom emerged. According to the Oxford English Dictionary, the earliest reference to the term "Western world" was from 1586, found in the writings of William Warner.

The 2018 Moscow–Constantinople schism is an ongoing schism between the Russian Orthodox Church (ROC, also known as the Moscow Patriarchate) and the Ecumenical Patriarchate of Constantinople, which began on 15 October 2018 when the former unilaterally severed full communion with the latter.

The resolution was taken in response to a decision of the Holy Synod of the Ecumenical Patriarchate of Constantinople of 11 October 2018, confirming its intentions to grant autocephaly to the Orthodox Church of Ukraine in the future. The decision also stated that the Holy Synod would immediately: reestablish a stauropegion in Kyiv, i.e. a church body subordinated directly to the ecumenical patriarch; revoke the "Letter of issue" (permission) of 1686 that had given permission to the patriarch of Moscow to ordain the metropolitan of Kiev and lift the excommunications which affected the clergy and faithfuls of two unrecognized Ukrainian Eastern Orthodox churches. Those two unrecognized churches, the Ukrainian Autocephalous Orthodox Church (UAOC) and the Ukrainian Orthodox Church – Kyiv Patriarchate (UOC-KP), were competing with the Ukrainian Orthodox Church (Moscow Patriarchate) (UOC-MP) and were considered "schismatics" (illegally segregated groups) by the Patriarchate of Moscow, as well as by the other Eastern Orthodox churches.

The Reform War (17 December 1857 – 11 January 1861) or War of Reform (Spanish: Guerra de Reforma), also known as the Three Years' War (Spanish: Guerra de los Tres Años), and the Mexican Civil War, was a complex civil conflict in Mexico fought between Mexican liberals and conservatives with regional variations over the promulgation of Constitution of 1857. It has been called the "worst civil war to hit Mexico between the War of Independence of 1810–21 and the Revolution of 1910–20". Following the liberals' overthrow of the dictatorship of conservative Antonio López de Santa Anna, liberals passed a series of laws codifying their political program. These laws were incorporated into the new constitution. It aimed to limit the political power of the executive branch, as well as the political, economic, and cultural power of the Catholic Church. Specific measures were the expropriation of Church property; separation of church and state; reduction of the power of the Mexican Army by elimination of their special privileges; strengthening the secular state through public education; and measures to develop the nation economically.

The constitution had been promulgated on 5 February 1857 was to come into force on 16 September 1857. There was intense opposition from Conservatives and the Catholic Church over its anti-clerical provisions, but there were also moderate liberals, including President Ignacio Comonfort, who considered the constitution too radical and likely to trigger a civil war. The Lerdo Law forced the sale of most of the Church's rural properties. The measure was not exclusively aimed at the Catholic Church, but also Mexico's indigenous peoples, which were forced to sell sizeable portions of their communal lands. Controversy was further inflamed when the Catholic Church decreed the excommunication of civil servants who took a government-mandated oath upholding the new constitution, which left Catholic civil servants with the choice of losing their jobs or being excommunicated.

Heresy is any belief or theory that is strongly at variance with established beliefs or customs, particularly the accepted beliefs or religious law of a religious organization. A heretic is a proponent of heresy.

Heresy in Judaism, Christianity, and Islam has at times been met with censure ranging from excommunication to the death penalty.

The Ukrainian Orthodox Church – Kyiv Patriarchate (UOC-KP; Ukrainian: Украї́нська Правосла́вна Це́рква – Ки́ївський Патріарха́т (УПЦ-КП), romanized: Ukrainska Pravoslavna Tserkva — Kyivskyi Patriarkhat (UPTs-KP)) was an Orthodox church in Ukraine, in existence from 1992 to 2018. Its patriarchal cathedral was St Volodymyr's Cathedral in Kyiv.

After its unilateral declaration of autocephaly in 1992, the UOC-KP was not recognised by the other Eastern Orthodox churches, and was considered a "schismatic group" by the Moscow Patriarchate and Ecumenical Patriarchate. Patriarch Filaret (Denysenko) was enthroned in 1995 and excommunicated by the Russian Orthodox Church in 1997, an action not recognized by the UOC-KP synod. In 2018, the Ecumenical Patriarchate of Constantinople moved unilaterally and against canonical norms to facilitate a "unification council", in contradiction to his previous statement "recognizing the fullness of the Russian Orthodox Church's exclusive competence on this issue". The canonical Ukrainian Orthodox Church rejected these overtures, noting its universal recognition as sole canonical authority on the territory of Ukraine and the political nature of the proposed council. Constantinople ignored this, "reinstated" Filaret as a bishop and facilitated the convening of a unification council. In December 2018, the unification council of the Eastern Orthodox churches of Ukraine decided to unite the UOC-KP with the Ukrainian Autocephalous Orthodox Church (UAOC), creating the Orthodox Church of Ukraine (OCU) which was subsequently granted autocephaly by the Ecumenical Patriarch of Constantinople in January 2019.

In the canon law of the Catholic Church, excommunication (Lat. ex, "out of", and communio or communicatio, "communion"; literally meaning "exclusion from communion") is a form of censure. In the formal sense of the term, excommunication includes being barred not only from the sacraments but also from the fellowship of Christian baptism. The principal and severest censure, excommunication presupposes guilt; and being the most serious penalty that the Catholic Church can inflict, it supposes a grave offense. The excommunicated person is considered by Catholic ecclesiastical authority as an exile from the Church, for a time at least.

Excommunication is intended to invite the person to change behaviour or attitude, repent, and return to full communion. It is not an "expiatory penalty" designed to make satisfaction for the wrong done, much less a "vindictive penalty" designed solely to punish. Excommunication, which is the gravest penalty of all, is always "medicinal".
