"Heresy"

Definition: Heresy is used to describe a doctrine that is unacceptable to the established Christian church and is considered false. Schism is distinct from heresy in that a schism creates a division in the church. Excommunication has been the traditional method of dealing with heretics. In Roman Catholicism, the term heresy has been used to refer to the denial of a religious truth by a baptized member of the Chhurch.
