Christian Heresies

Monophysite comes from the Greek words for "one body." This heresy says that Jesus Christ was a joining of the eternal Logos with the human person Jesus, which occured at incarnation. He therefore is two separate natures joined in one body. Monophysitism is very much alive in several present-day Egyptian and Middle Eastern sects of Christianity.

Arianism is named after Arius (c. 250 - c. 336), a priest in Alexandria. This is considered the most serious heresy. Jesus Christ was thought of as a special creation by God for man's salvation. Arianism was the form of Christianity that the Goths adhered to, and it was popular in all the areas they conquered, including Italy, Spain, and Africa.

Named for Apollinaris of Laodicea (fl. AD 350), this heresy says that Jesus Christ was not a real man, but not totally divine either. Apollinarians suggested that he had a human body and a human soul, but his mind was taken over by the eternal Logos.

Named for its leader, the theologian Donatus the Great (d. 355), Donatism included a group of extremist sects, mostly in North Africa, that emphasized asceticism. They valued martyrdom, found lapses of faith (even under torture or threat of death) inexcusable, and believed that the sacraments required a pure priest to be effective.

A number of sects, centered in Gaul, Britain, and Ireland, were associated with the Irish monk Pelagius (fl. 410). He believed that original sin was not transmitted from Adam and Eve to their children (and thereby to us). Baptism was not considered necessary, and people could be "saved" by their own efforts, that is, they did not necessarily require the grace of God. Many modern liberal Christians agree with Pelagius.

Some believe that Nestorius, Patriarch of Antioch (c. 410), believed that Jesus Christ had two natures -- man and God , and that these remained separate throughout his time on earth. Although this is not actually what Nestor said, the designation stuck. Today there are still Nestorian churches in Iran.
