"Discernment is not a matter of simply telling the difference between right and wrong; rather, it is the difference between right and almost right." - Charles Spurgeon
What is Polemics?
Polemics is the study and practice of discerning the difference between sound doctrine, heterodoxy, and heresy. When one practices polemics, that person studies the beliefs or actions of a supposedly Christian person or group in order to understand whether or not they are truly Christians, and if they are false teachers or cults the job is then to warn the Church about that false teacher or cult. Polemics requires a knowledge of cults, false teachers both past and present, and both heresies and essential orthodox doctrines.
