A heretic is a person who holds beliefs that differ from established religious doctrine. The term is also used more broadly for anyone who rejects accepted standards.

What it is

Dictionary definitions consistently describe a heretic as someone who departs from accepted religious doctrine, especially within a faith the person is understood to belong to. The word is usually pejorative, particularly in religious contexts, and can also apply more generally to unorthodox opinions in any field.

Religious context

In Christian usage, especially Roman Catholic tradition, the term traditionally refers to a baptized believer who rejects official church doctrines. This religious sense is the most established historical usage, though the word is also used metaphorically in modern commentary.

Broader modern use

Outside religion, heretic may describe a nonconformist or dissenter whose ideas go against accepted standards. This metaphorical usage is common in journalism and informal speech, sometimes even used positively to describe someone who challenges conventional thinking.

In short
