They want to know, "If someone says, ‘Look at all the hypocrites in the church!' what do I say?" There's nothing wrong with that question but the fact remains that such practical matters are logically secondary to the theoretical issues and cannot in our limited space occupy the center of our attention. They're just not interested in the rational justification of Christianity. Now this is bound to be disappointing to some. This implies that a course in apologetics is not for the purpose of teaching you, "If he says so-and-so, then you say such-and-such back." Apologetics, to repeat, is a theoretical discipline that tries to answer the question, What rational warrant can be given for the Christian faith? Therefore, most of our time must be spent in trying to answer this question.

As a theoretical discipline, then, apologetics is not training in the art of answering questions, or debating, or evangelism, though all of these draw upon the science of apologetics and apply it practically. In addition to serving, like the rest of theology in general, as an expression of loving God with all our minds, apologetics specifically serves to show to unbelievers the truth of the Christian faith, to confirm that faith to believers, and to reveal and explore the connections between Christian doctrine and other truths. Apologetics is thus primarily a theoretical discipline, though it has a practical application. What is apologetics? Apologetics (from the Greek apologia: a defense) is that branch of Christian theology which seeks to provide a rational justification for the truth claims of the Christian faith.
