Presuppositional apologetics

Presuppositional apologetics is a school of Christian apologetics, a field of Christian theology that attempts to present a rational basis for the Christian faith, defend the faith against objections, and attack the alleged flaws of other worldviews. Presuppositional apologetics is especially concerned with the third aspect of this discipline, though it generally sees the trifold distinction as a difference in emphasis rather than as delineating three separate endeavors. Presuppositional apologetics developed in and is most commonly advocated within Reformed circles of Christianity.

The key discriminator of this school is that it maintains that the Christian apologist must assume the truth of the supernatural revelation contained in the Bible (that is, the Christian worldview) because there can be no set of neutral assumptions from which to reason with a non-Christian. In other words, presuppositionalists say that a Christian cannot consistently declare his belief in the necessary existence of the God of the Bible and simultaneously argue on the basis of a different set of assumptions (presumably those of the non-Christian) in which God may or may not exist.
