Apologetics is not only the convergence of theological categories, bringing together the study of the Old Testament, Biblical languages, systematic theology, and so forth. It’s also an integration of all academic disciplines through a Christian worldview. To do holistic, effective apologetics, one should integrate their systematic theology with theologically-informed psychology, theologically-informed sociology, theologically-informed biology, and so on. Apologetics may begin with the teachings of Scripture, but it extends to anywhere God’s truth exists and then subsequently seeks to apply and articulate that truth for the defense of the faith. — Christopher Talbot (from, Proving the Existence of Apologetics)
