History of Christian Theology - Early Heresies

Early Heresies

Urgent concerns with the uniformity of belief and practice have characterized Christianity from the outset. The New Testament itself speaks of the importance of maintaining orthodox doctrine and refuting heresies, showing the antiquity of the concern. The development of doctrine, the position of orthodoxy, and the relationship between the early Church and early heretical groups is a matter of academic debate. Some scholars, drawing upon distinctions between Jewish Christians, Gentile Christians, and other groups such as Gnostics, see Early Christianity as fragmented and with contemporaneous competing orthodoxies.

The process of establishing orthodox Christianity was set in motion by a succession of different interpretations of the teachings of Christ being taught after the crucifixion. Though Christ himself is noted to have spoken out against false prophets and false christs within the gospels themselves Mark 13:22 (some will arise and distort the truth in order to draw away disciples), Matthew 7:5-20, Matthew 24:4, Matthew 24:11 Matthew 24:24 (For false christs and false prophets will arise). On many occasions in Paul's epistles, he defends his own apostleship, and urges Christians in various places to beware of false teachers, or of anything contrary to what was handed to them by him. The epistles of John and Jude also warn of false teachers and prophets, as does the writer of the Book of Revelation and 1 Jn. 4:1, as did the Apostle Peter warn in 2 Pt. 2:1-3:.

One of the roles of bishops, and the purpose of many Christian writings, was to refute heresies. The earliest of these were generally Christological in nature, that is, they denied either Christ's (eternal) divinity or humanity. For example, Docetism held that Jesus' humanity was merely an illusion, thus denying the incarnation; whereas Arianism held that Jesus was not eternally divine. Many groups were dualistic, maintaining that reality was composed into two radically opposing parts: matter, usually seen as evil, and spirit, seen as good. Orthodox Christianity, on the other hand, 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.

Irenaeus (c. 130–202) was the first to argue that his "proto-orthodox" position was the same faith that Jesus gave to the apostles, and that the identity of the apostles, their successors, and the teachings of the same were all well-known public knowledge. This was therefore an early argument supported by apostolic succession. 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.

In the middle of the 2nd century, three groups of Christians adhered to a range of doctrines that divided the Christian communities of Rome: the teacher Marcion, the pentecostal outpourings of ecstatic Christian prophets of a continuing revelation, in a movement that was called "Montanism" because it had been initiated by Montanus and his female disciples, and the gnostic teachings of Valentinus. 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 (ca 180, in five volumes), written in Lyons after his return from a visit to Rome. The letters of Ignatius of Antioch and Polycarp of Smyrna to various churches warned against false teachers, and the Epistle of Barnabas accepted by many Christians as part of Scripture in the 2nd century, warned about mixing Judaism with Christianity, as did other writers, leading to decisions reached in the first ecumenical council, which was convoked by the Emperor Constantine at Nicaea in 325, in response to further disruptive polemical controversy within the Christian community, in that case Arian disputes over the nature of the Trinity.

During those first three centuries, Christianity was effectively outlawed by requirements to venerate the Roman emperor and Roman gods. Consequently, when the Church labelled its enemies as heretics and cast them out of its congregations or severed ties with dissident churches, it remained without the power to persecute them. However, those called "heretics" were also called a number of other things (e.g. "fools," "wild dogs," "servants of Satan"), so the word "heretic" had negative associations from the beginning, and intentionally so.

Before 325 AD, the "heretical" nature of some beliefs was a matter of much debate within the churches. After 325 AD, some opinion was formulated as dogma through the canons promulgated by the councils.
