List of Christian heresies

This article is about Christian heresies regardless of denomination. For heresies condemned by the Catholic Church, see List of heresies in the Catholic Church.

A heresy is a belief or doctrine that is considered to be false or erroneous by one or more Christian denominations, i.e. what is believed to be contrary to the teaching of Christianity. Heresies have been a major source of division and conflict within Christendom throughout its history. Christian churches have responded to heresies in a variety of ways, including through theological debate, excommunication, and even violence.[1] This is a list of some of the Christian heresies that have been condemned by one or more Christian Churches.

The Byzantine Emperor Justinian desired to reunite the Miaphysite and Chalcedonian Churches throughout Byzantium, and so anathematized the Three Chapters and commanded Byzantine bishops (which included at the time the Pope) to do so as well. Pope Vigilius however believed doing so would undermine the authority of Chalcedon, and so initially refused to do so. Eventually, after incarceration and deportation to Constantinople, he agreed to anathematize the Three Chapters and concur with the Emperor in December of 553.[34]
