heretic
One who having professed the faith of Christ corrupts its dogmas. He may be a material heretic, adhering to heresy innocently or from involuntary causes, or a formal heretic, knowingly and freely adhering to heresy . One who holds opinions at variance with recognized teachings in philosophy, science, or art; since the term is somewhat odious, it is more properly applied to the originators of heresy than to their descendants and remote followers.
