misbeliever
One holding false faith
A misbeliever is someone who holds false or heretical beliefs, particularly in religious contexts.
The term carries judgment—it assumes the speaker's beliefs are correct and the misbeliever's are wrong.
Historically used by religious authorities against those deemed heretics or infidels: The inquisitors condemned the misbelievers.
Now rare and archaic outside historical or literary contexts.
