جدایی (انشقاق) یا شیزم (گاهی با تلفظ سکیزم یا اسکیزم) (به انگلیسی: schism) نوعی از جدا شدن مردم از هم است که معمولاً به وابستگی به یک سازمان، جنبش، یا مذهب دینی اشاره دارد. این کلمه اغلب برای اشاره به جدایی از یک دین که قبلاً یکپارچه بوده است به کار میرود؛ مانند جدایی شرق و غرب یا دو دستگی غرب یا جدایی ۱۵۵۲. از لغت شیزم همچنین در مورد به وجود آمدن انشعاب در یک سازمان غیر دینی یا جنبش یا به طور گستردهتر، در مورد جدایی بین دو نفر یا بیشتر هم به کار میرود؛ از جمله در مورد برادران، دوستان یا عشاق.
A schism (pronounced // SIZ-əm, // SKIZ-əm or, less commonly, // SHIZ-əm) is a division between people, usually belonging to an organization, movement, or religious denomination. The word is most frequently applied to a split in what had previously been a single religious body, such as the East–West Schism or the Great Western Schism. It is also used of a split within a non-religious organization or movement or, more broadly, of a separation between two or more people, be it brothers, friends, lovers, etc.
A schismatic is a person who creates or incites schism in an organization or who is a member of a splinter group. Schismatic as an adjective means pertaining to a schism or schisms, or to those ideas, policies, etc. that are thought to lead towards or promote schism.
In religion, the charge of schism is distinguished from that of heresy, since the offence of schism concerns not differences of belief or doctrine but promotion of, or the state of, division. However, schisms frequently involve mutual accusations of heresy. In Roman Catholic teaching, every heresy is a schism, while there may be some schisms free of the added guilt of heresy. Liberal Protestantism, however, has often preferred heresy over schism. Presbyterian scholar James I. McCord (quoted with approval by the Episcopalian Bishop of Virginia Peter Lee) drew a distinction between them, teaching: "If you must make a choice between heresy and schism, always choose heresy. As a schismatic, you have torn and divided the body of Christ. Choose heresy every time."
The word schism comes from the greek word 'σχίσμα' which means cleft, division.
In Buddhism, the first schism was set up by Devadatta, during Buddha's life. This schism lasted only a short time. Later (after Buddha's death), the early Buddhist schools came into being, but were not schismatic, only focusing on different interpretations for the same monastic community. In the old texts, 18 or 20 early schools are mentioned. Later, there were the Mahayana and Vajrayana movements, which can be regarded as being schismatic in origin. Each school has various subgroups, which often are schismatic in origin. For example, in Thai Theravadin Buddhism there are two groups (Mahanikaya and Dhammayut), of which the Dhammayut has its origin partly in the Mahanikaya, and is the new and schismatic group. Both Mahanikaya and Dhammayut have many subgroups, which usually do not have schismatic origins, but came into being in a natural way, through the popularity of a (leader) monk. Tibetan Buddhism has seen schisms in the past, of which most were healed, although the Drukpa school centred in Bhutan perhaps remains in a state of schism (since 1616) from the other Tibetan schools.
The words schism and schismatic have found their heaviest usage in the history of Christianity, to denote splits within a church, denomination or religious body. In this context, "schismatic", as a noun, denotes a person who creates or incites schism in a church or a person who is a member of a splinter Church; as an adjective, "schismatic" refers to ideas and activities that are thought to lead to or constitute schism, and ultimately departure from what the user of the word considers to be the true Christian Church. These words have been used to denote both the phenomenon of Christian group splintering in general, and certain significant historical splits in particular.
A distinction is made between heresy and schism. Heresy is rejection of a doctrine that a Church considered to be essential. Schism is a rejection of communion with the authorities of a Church, and not every break of communion is necessarily about doctrine, as is clear from examples such as the Western Schism and the breaking of communion between Patriarch Bartholomew I of Constantinople and Archbishop Christodoulos of Athens in 2004. But, when for any reason people withdraw from communion, two distinct ecclesiastical entities may result, each of which then, or at least some of its members, may accuse the other of heresy.
In Roman Catholic Church canon law, an act of schism, like an act of apostasy or heresy, automatically brings the penalty of excommunication on the individual who commits it. As stated in canon 1312 §1 1° of the Code of Canon Law, this penalty is intended to be medicinal, so as to lead to restoration of unity. Roman Catholic theology considers formal schismatics to be outside the Church, understanding by "formal schismatics" "persons who, knowing the true nature of the Church, have personally and deliberately committed the sin of schism". The situation, for instance, of those who have been brought up from childhood within a group not in full communion with Rome, but who have orthodox faith, is different: these are considered to be imperfectly, though not fully, members of the Church. This nuanced view applies especially to the Churches of Eastern Christianity, more particularly still to the Eastern Orthodox Church.
The First Council of Nicaea (A.D. 325) distinguished between schism and heresy. It declared Arian and non-Trinitarian teachings to be heretical and excluded their adherents from the Church. It also addressed the schism between Peter of Alexandria and Meletius of Lycopolis, considering their quarrel to be a matter of discipline, not of faith.
The divisions that came to a head at the Councils of Ephesus (A.D. 431) and Chalcedon (A.D. 451) were seen as matters of heresy, not merely of schism. Thus, the Eastern Orthodox Church and Oriental Orthodoxy consider each other to be heretical, not orthodox, because of the Oriental Orthodox Church's rejection and the Eastern Orthodox Church's acceptance of the Confession of Chalcedon about the two natures, human and divine, of Christ. However, this view has been challenged in the recent Ecumenical discussion between these two groups, bringing the matter of Chalcedon as a matter of schism, not of heresy.
In its extended and final form (possibly derived from the First Council of Constantinople in 381 although only known from the Acts of the Council of Chalcedon seventy years later), what is commonly called the Nicene Creed declares belief in the One Holy Catholic and Apostolic Church. Some who accept this creed believe they should be united in a single Church or group of Churches in communion with each other. Others who accept this creed believe it does not speak of a visible organization but of all those baptized who hold the Christian faith, referred to as Christendom. Some churches consider themselves to be the One Holy Catholic and Apostolic Church. For instance, the Roman Catholic Church claims that title and considers the Eastern Orthodox Church to be in schism, while the Eastern Orthodox Church also claims that title and holds the view that the Catholic Church is schismatic. Some Protestant Churches believe that they also represent the One Holy Catholic and Apostolic Church and consider the Catholic and Orthodox Churches to be in error, while others do not expect a union of all Christian churches on earth. See also One true church and Great Apostasy.
Schisms are particularly prevalent among Anabaptists, to the extent that divisions over even minute details of doctrine and theology are common and the issue has been called by scholars Täuferkrankheit or "The Anabaptist Disease". Emphasizing fully voluntary membership in the church, and without an established authority of hierarchical structure, Anabaptists, especially Mennonites have had dozens of schisms establishing dozens of various unaffiliated Mennonite churches.
In 2018 Eastern Orthodoxy suffered a schism, the 2018 Moscow-Constantinople schism between the primatial See of Eastern Orthodoxy, the Ecumenical Patriarchate of Constantinople and the Russian Orthodox Church over the issue of Constantinople granting Autocephaly to the Orthodox Church of Ukraine.
After the death of the Islamic prophet Muhammed, there have arisen many Muslim sects by means of schools of thought, traditions and related faiths. According to a Hadith report (collections of accounts of the life and teachings of Muhammed), Muhammed is said to have prophesied "My Ummah (Community or Nation) will be fragmented into seventy-three sects, and all of them will be in the Hell fire except one." The Sahaba (his companions) asked him which group that would be, whereupon he replied, "It is the one to which I and my companions belong" (reported in Sunan al-Tirmidhi Hadith No. 171).
Sunni Muslims, often referred to as Ahl as-Sunnah wa’l-Jamā‘h or Ahl as-Sunnah, are the largest denomination of Islam. The word Sunni comes from the word Sunnah, which means the teachings and actions or examples of the Islamic prophet, Muhammad; therefore, the term Sunni refers to those who follow or maintain the Sunnah of Muhammad. The Sunni believe that Muhammad died without appointing a successor to lead the Muslim ummah (community). After an initial period of confusion, a group of his most prominent companions gathered and elected Abu Bakr, Muhammad's close friend and father-in-law, as the first Caliph. Sunnis regard the first four caliphs - Abu Bakr, Umar (`Umar ibn al-Khattāb), Uthman Ibn Affan, and Ali (Ali ibn Abu Talib) - as the al-Khulafā’ur-Rāshidūn or "Rashidun" (The Rightly Guided Caliphs). Sunnis believe that the position of Caliph may be democratically chosen, but after the first four Rightly Guided Caliphs the position turned into a hereditary dynastic rule. There has not been another widely recognized Caliph since the fall of the Ottoman Empire in 1923.
Shia Islam is the second largest denomination of Islam. Shia Muslims believe that, similar to the appointment of prophets, Imams after Muhammad are also chosen by God. According to Shias, Ali was chosen by Allah and thus appointed by Muhammad to be the direct successor and leader of the Muslim community. They regard him as the first Shia Imam, which continued as a hereditary position through Fatimah and Ali's descendants.
Sufism is a mystical-ascetic form of Islam practised by both Shia and Sunni Muslims. Some Sufi followers consider themselves Sunni or Shia, while others consider themselves as just Sufi or Sufi-influenced. Sufism is usually considered to be complementary to orthodox Islam, although Sufism has often been accused by the salafi of being an unjustified Bid‘ah or religious innovation. By focusing on the more spiritual aspects of religion, Sufis strive to obtain direct experience of God by making use of "intuitive and emotional faculties" that one must be trained to use. One starts with sharia (Islamic law), the exoteric or mundane practice of Islam, and then is initiated into the mystical (esoteric) path of a Tariqah (Sufi Order).
Kharijite (lit. "those who seceded") is a general term embracing a variety of Islamic sects which, while originally supporting the Caliphate of Ali, eventually rejected his legitimacy after he negotiated with Mu'awiya during the 7th Century Islamic civil war (First Fitna). Their complaint was that the Imam must be spiritually pure, whereas Ali's compromise with Mu'awiya was a compromise of his spiritual purity and therefore of his legitimacy as Imam or Caliph. While there are few remaining Kharijite or Kharijite-related groups, the term is sometimes used to denote Muslims who refuse to compromise with those with whom they disagree.
Throughout Jewish history, Judaism survived many schisms, including the emergence of Christianity. Today, major Jewish denominations are Orthodox Judaism and non-Orthodox: Reform, Conservative and Reconstructionist.
