Christian heresy

Heresy, as a blanket term, describes a practice or belief that is labeled as unorthodox. Christian heresy refers to unorthodox practices and beliefs that were deemed to be heretical by one or more of the Christian churches. The term "heresy" most commonly refers to those beliefs which were declared to be anathema by the Church prior to the schism of 1054. However, since that time, various Christian churches have also used the concept in proceedings against individuals and groups deemed to be heretical by those churches.
