Christianity is unique in that its veracity depends on the reality of particular historical events.  Christianity is not a philosophical religion.  Christian faith is not faith for the sake of faith, but a particular understanding about the significance of particular historical events—events that were either supernatural in character, or pregnant with supernatural significance.  If these purported historical events are actually fictional or mythical in nature, the very foundation of Christianity crumbles.

While our faith depends on the veracity of particular historical events through which God revealed Himself and His purposes, there is no question that we believe much more than can be demonstrated historically.  Historical and archaeological investigation can only verify and bolster some of the Bible’s historical claims.  While it can cover a lot of ground, the remaining gaps still must be transposed by faith.  That faith is not a blind and absurd leap as Kierkegaard suggested, but a reasoned judgment in reality based on the evidence available to us.
