“If we are to defend Christian theism as a unit it must be shown that its parts are really related to one another. We have already indicated the relation between the doctrine of Christ’s work, the doctrine of sin, and the doctrine of God. The whole curriculum of an orthodox seminary is built upon the conception of Christian theism as a unit. The Bible is at the center not only of every course, but at the center of the curriculum as a whole. The Bible is thought of as authoritative on everything of which it speaks. Moreover, it speaks of everything. We do not mean that it speaks of football games, of atoms, etc., directly, but we do mean that it speaks of everything either directly or by implication. It tells us not only of the Christ and his work, but it also tells us who God is and where the universe about us has come from. It tells us about theism as well as about Christianity. It gives us a philosophy of history as well as history. Moreover, the information on these subjects is woven into an inextricable whole. It is only if you reject the Bible as the word of God that you can separate the so-called religious and moral instruction of the Bible from what it says, e.g., about the physical universe.
This view of Scripture, therefore, involves the idea that there is nothing in this universe on which human beings can have full and true information unless they take the Bible into account. We do not mean, of course, that one must go to the Bible rather than to the laboratory if one wishes to study the anatomy of the snake. But if one goes only to the laboratory and not also to the Bible one will not have a full or even true interpretation of the snake.” – Van Til, Christian Apologetics Chapter 1 The System of Christian Truth
