In early [[Christianity]], '''heresy''' was a recurring problem as people pretending to be [[Christian]]s would advocate doctrines contrary to the [[Bible]]. As heresy was seen as a great threat to the church, spurious allegations of heresy were also used by rival ecclesiarchs to attack their enemies. A series of [[Councils]] were held to establish official doctrine, in some cases leading to [[Great Schism|schisms]], such as the split between the [[Roman Catholic]] and [[Eastern Orthodox]] Churches in the eleventh century.

Today, accusations of heresy are not as widespread as they once were, but some Christians may privately consider those of other denominations to be heretics.
