Heresy in Christianity in the context of "Manicheism"

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.

Tertullian (/tərˈtʌliən/; Latin: Quintus Septimius Florens Tertullianus; c. 155 – c. 220 AD) was a prolific early Christian author from Carthage in the Roman province of Africa. He was the first Christian author to produce an extensive corpus of Latin Christian literature and was an early Christian apologist and a polemicist against heresy, including contemporary Christian Gnosticism.

Tertullian was the first theologian to write in Latin, and so has been called "the father of Latin Christianity", as well as "the founder of Western theology". He is perhaps most famous for being the first writer in Latin known to use the term trinity (Latin: trinitas).

Manichaeism (/ˌmænɪˈkiːɪzəm/; in Persian: آئین مانی, romanized: Āʾīn-i Mānī; Chinese: 摩尼教; pinyin: Móníjiào) was a major world religion founded in the third century CE by the Parthian Iranian prophet Mani (C.E. 216–274) in the Sasanian Empire. Variably described as a Christian heresy and a Gnostic movement, Manichaeism was an organized and doctrinal religious tradition in its own right. It taught an elaborate dualistic cosmology describing the struggle between a good spiritual world of light, and an evil material world of darkness. Through an ongoing process that takes place in human history, light is gradually removed from the world of matter and returned to the world of the divine.

Mani's teachings were intended to integrate, succeed, and surpass the "partial truths" of various prior faiths and belief systems, including Platonism, Christianity, Zoroastrianism, Buddhism, Marcionism, Hellenistic and Rabbinic Judaism, Gnostic movements, Ancient Greek religion, Babylonian and other Mesopotamian religions, and mystery cults. Some forms of Manichaeism see Mani as the final prophet after Zoroaster, the Buddha, and Jesus. The Manichaean scriptural canon includes seven works attributed to Mani, written originally in Syriac. Manichaean sacramental rites included prayers, almsgiving, and fasting. Communal life centered on confession and the singing of hymns.

A papal legate or apostolic legate (from the ancient Roman title legatus) is a personal representative of the Pope to foreign nations, to some other part of the Catholic Church, or to representatives of a state or monarchy. A legate is empowered in matters of Catholic faith and for the settlement of ecclesiastical matters.

The legate is appointed directly by the Pope—the Bishop of Rome and head of the Catholic Church. Hence a legate is usually sent to a government, to a sovereign, to a large body of believers (such as a national church), or to take charge of a major religious effort, such as an ecumenical council, a crusade to the Holy Land, or even against a heresy such as the Cathars.

The persecution of Christians can be traced from the first century of the Christian era to the present day. Christian missionaries and converts to Christianity have both been targeted for persecution, sometimes to the point of being martyred for their faith, ever since the emergence of Christianity.

Early Christians were persecuted at the hands of both Jews, from whose religion Christianity arose, and the Romans who controlled many of the early centers of Christianity in the Roman Empire. Since the emergence of Christian states in Late Antiquity, Christians have also been persecuted by other Christians due to differences in doctrine which have been declared heretical. Early in the fourth century, the empire's official persecutions were ended by the Edict of Serdica in 311 and the practice of Christianity legalized by the Edict of Milan in 312. By the year 380, Christians had begun to persecute each other. The schisms of late antiquity and the Middle Ages – including the Rome–Constantinople schisms and the many Christological controversies – together with the later Protestant Reformation provoked severe conflicts between Christian denominations. During these conflicts, members of the various denominations frequently persecuted each other and engaged in sectarian violence.

Arianism (Koine Greek: Ἀρειανισμός, Areianismós) is a Christological doctrine that rejects the traditional notion of the Trinity, teaching that Jesus was created by God and is therefore distinct from God. It is named after its proponent Arius (250 or 256 – 336) and is regarded as heretical by most modern mainstream branches of Christianity. Arianism is held by a minority of modern denominations, although some of these groups espouse related doctrines such as Socinianism, and others avoid the term "Arian" because of its historically negative connotations. Modern denominations sometimes associated with the teaching include Jehovah's Witnesses, some churches within the Churches of Christ (among them the movement's founder, Barton W. Stone), and certain Hebrew Roots Christians and Messianic Jews, although many Messianic Jews adhere to Nicene Christianity. The Arian view is also held by The Church of Jesus Christ of Latter Day Saints, although the theology is more distinct in key ways.

It is first attributed to Arius, a Christian presbyter who preached and studied in Alexandria, Egypt, although it developed out of various preexisting strands of Christianity which differed from later Nicene Christianity in their view of Christology. Arian theology holds that Jesus Christ is the Son of God, who was begotten by God the Father with the difference that the Son of God did not always exist but was begotten/made before time by God the Father; therefore, Jesus was not coeternal with God the Father, but nonetheless Jesus began to exist outside time.

In Christianity, a schism occurs when a single religious body divides and becomes two separate religious bodies. The split can be violent or nonviolent but results in at least one of the two newly created bodies considering itself distinct from the other. This article covers schisms in Christianity.

In the early Christian church, the formation of a distinction between the concepts of "heresy" and "schism" began. In ecclesiastical usage, the term "heresy" refers to a serious confrontation based on disagreements over fundamental issues of faith or morality, while the term "schism" usually means a lesser form of disunity caused by organizational or less important ideological differences. 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.
