Apologetics
The term apologetics comes from the Greek apologia, which means "defense" or "answer." Apologetics is the task of defending a particular idea or belief system and answering its critics. The origin of the concept of apologetics lies in the beginnings of Christianity. Between the second and fourth century, a number of Christian teachers wrote defenses of Christianity against pagan critics.
