Etymology

The word ''heresy'' comes from ''haeresis'', a Latin transliteration of the Greek word originally meaning choosing, choice, course of action, or in an extended sense a sect or school of thought, which by the first century came to denote warring factions and the party spirit. The word appears in the New Testament, usually translated as '' sect'', and was appropriated by the Church to mean a sect or division that threatened the unity of Christians. Heresy eventually became regarded as a departure from

Early Christianity (1st century – c. 325 AD)

, and the relationship between the early Church and early heretical groups is a matter of academic debate. Walter Bauer, in his ''Orthodoxy and Heresy in Earliest Christianity'' (1934/1971), proposed that in earliest Christianity, orthodoxy and heresy did not stand in relation to one another as primary to secondary, but in many regions heresy was the original manifestation of Christianity. Bauer reassessed as a historian the overwhelmingly dominant view that for the period of Christian origins, ecclesiastical doctrine already represented what is primary, while heresies, on the other hand somehow are a deviation from the genuine (Bauer, "Introduction"). Scholars such as Pagels and Ehrman have built on Bauer's original thesis. Drawing upon distinctions between Jewish Christians, Gentile Christians, and other groups such as Gnostics and Marcionites, they argue that early Christianity was fragmented, and with contemporaneous competing orthodoxies. Ehrman's view is that while the specifics of Bauer's demonstration were later rejected, his intuitions are broadly accepted by scholars and were confirmed beyond what Bauer might have guessed. According to
H. E. W. Turner Henry Ernest William "Hugh" Turner (14 January 1907 – 14 December 1995) was an English Anglican priest, theologian, and academic. Having served his curacy in the Diocese of Carlisle, Turner spent most of the next four decades of his ordained m ...
, responding to Bauer's thesis in 1954, "what became official orthodoxy was taught early on by the majority of church teachers, albeit not in fully developed form." According to Darrell Bock, a Christian apologist, Bauer's theory does not show an equality between the established church and outsiders including Simon Magus. According to Mitchell et al., each early Christian community was unique, but the tenets of the mainstream or catholic Church insured that each early Christian community did not remain isolated.
G. K. Chesterton Gilbert Keith Chesterton (29 May 1874 – 14 June 1936) was an English writer, philosopher, Christian apologist, and literary and art critic. He has been referred to as the "prince of paradox". Of his writing style, ''Time'' observed: "Wh ...

Proto-orthodoxy

Before AD 313, the heretical nature of some beliefs was a matter of much debate within the churches, and there was no true mechanism in place to resolve the various differences of beliefs. Heresy was to be approached by the leader of the church according to Eusebius, author of the '' Church History''. Early attacks upon alleged heresies formed the matter of Tertullian's ''Prescription Against Heretics'' (in 44 chapters, written from Rome), and of Irenaeus' ''
Against Heresies ''Against Heresies'' (Ancient Greek: Ἔλεγχος καὶ ἀνατροπὴ τῆς ψευδωνύμου γνώσεως, ''Elenchos kai anatropē tēs pseudōnymou gnōseōs'', "On the Detection and Overthrow of the So-Called Gnosis"), some ...

. Irenaeus first established the doctrine of four gospels and no more, with the synoptic gospels interpreted in the light of '' John''. Irenaeus' opponents, however, claimed to have received secret teachings from Jesus via other apostles which were not publicly known. Gnosticism is predicated on the existence of such hidden knowledge, but brief references to private teachings of Jesus have also survived in the canonic Scripture as did warning by the Christ that there would be false prophets or false teachers. Irenaeus' opponents also claimed that the wellsprings of divine inspiration were not dried up, which is the doctrine of continuing revelation.


Late Antiquity (313–476) and Early Middle Ages (476–799)


Christology

The earliest controversies in Late Antiquity were generally Christological in nature, concerning the interpretation of Jesus' (eternal) divinity and humanity. In the 4th century,
Arius Arius (; grc-koi, Ἄρειος, ; 250 or 256 – 336) was a Cyrenaic presbyter, ascetic, and priest best known for the doctrine of Arianism. His teachings about the nature of the Godhead in Christianity, which emphasized God the Father's un ...

. The Euchites, a 4th-century antinomian sect from Macedonia held that the Threefold God transformed himself into a single hypostasis in order to unite with the souls of the perfect. They were anti-clerical and rejected baptism and the sacraments, believing that the passions could be overcome and perfection achieved through prayer. Many groups held dualistic beliefs, maintaining that reality was composed into two radically opposing parts: matter, usually seen as evil, and spirit, seen as good. Docetism held that Jesus' humanity was merely an illusion, thus denying the incarnation. Others held that both the material and spiritual worlds were created by God and were therefore both good, and that this was represented in the unified divine and human natures of Christ. The orthodox teaching, as it developed in response to these interpretations, is that Christ was fully divine and at the same time fully human, and that the three persons of the Trinity are co-equal and co-eternal.


Legal suppression of heresies

It was only after the legalisation of Christianity, which began under
Constantine I Constantine I ( , ; la, Flavius Valerius Constantinus, ; ; 27 February 22 May 337), also known as Constantine the Great, was Roman emperor from AD 306 to 337, the first one to convert to Christianity. Born in Naissus, Dacia Mediterranea ...
in AD 313 that the various beliefs of the proto-orthodox Church began to be made uniform and formulated as dogma, through the ''canons'' promulgated by the General Councils. The first known usage of the term 'heresy' in a civil legal context was in 380 by the " Edict of Thessalonica" of Theodosius I. Prior to the issuance of this edict, the Church had no state-sponsored support for any particular legal mechanism to counter what it perceived as 'heresy'. By this edict, in some senses, the line between the Christian Church's spiritual authority and the Roman State's jurisdiction was blurred. One of the outcomes of this blurring of Church and State was a sharing of State powers of legal enforcement between Church and State authorities, with the state enforcing what it determined to be orthodox teaching. Within five years of the official criminalization of heresy by the emperor, the first Christian heretic,
Priscillian Priscillian (in Latin: ''Priscillianus''; Gallaecia, - Augusta Treverorum, Gallia Belgica, ) was a wealthy nobleman of Roman Hispania who promoted a strict form of Christian asceticism. He became bishop of Ávila in 380. Certain practices of his f ...
, was executed in 385 by Roman officials. For some years after the Protestant Reformation, Protestant denominations were also known to execute those whom they considered heretics. The edict of Theodosius II (435) provided severe punishments for those who had or spread writings of Nestorius. Those who possessed writings of Arius were sentenced to death.


Ecumenical councils

Seven councils considered by main Christian denominations as ecumenical were convened between 325 and 787. These were mostly concerned with Christological disputes: #The First Ecumenical Council was convoked by the Roman Emperor Constantine at Nicaea in 325 and presided over by the Patriarch Alexander of Alexandria, with over 300 bishops condemning the view of

is that of Chalcedon in 451, with the Patriarch of Constantinople presiding over 500 bishops. This council affirmed that Jesus has two natures, is truly God and truly man, distinct yet always in perfect union. This was based largely on Pope Leo the Great's ''Tome''. Thus, it condemned Monophysitism and would be influential in refuting Monothelitism. #The Fifth Ecumenical Council is the second of Constantinople in 553, interpreting the decrees of Chalcedon and further explaining the relationship of the two natures of Jesus; it also condemned the teachings of Origen on the pre-existence of the soul, etc. #The Sixth Ecumenical Council is the third of Constantinople in 681; it declared that Christ has two wills of his two natures, human and divine, contrary to the teachings of the Monothelites. #The Seventh Ecumenical Council was called under the Empress Regent Irene of Athens in 787, known as the second of Nicaea.

From the late 11th century onward, heresy once again came to be a concern for Catholic authorities, as reports became increasingly common.
