A truly Protestant method of reasoning involves a stress upon the fact that the meaning of every aspect of Christian theism depends upon Christian theism as a unit. When Protestants speak of the resurrection of Christ, they speak of the resurrection of him who is the Son of God, the eternal Word through whom the world was made. The truth of theism is involved in the claim that Christians make with respect to the domain of history. And what is true of the resurrection of Christ is true with respect to all the propositions about historical fact that are made in Scripture. No proposition about historical fact is presented for what it really is till it is presented as part of the system of Christian theism that is contained in Scripture. To say this is involved in the consideration that all facts of the created universe are what they are by virtue of the plan of God with respect to them. Any fact in any realm contronted by man is what it is as revelational through and through of the God and of the Christ of Christian theism.

But if this is true–and it would seem to be of the very essence of the biblical point of view to say that it is true–then it follows that the whole claim of Christian theism is in question in any debate about any fact. Christian theism must be presented as that light in terms of which any proposition about any fact receives meaning. Without the presupposition of the truth of Christian theism no fact can be distinguished from any other fact. To say this is but to apply the method of idealist logicians in a way that these idealist logicians, because of their own anti-Christian-theistic assumptions, cannot apply it. The point made by these logicians is that even the mere counting of particular things presupposes a system of truth of which these particulars form a part.Withouth such a system of truth there would be no distinguishable difference between one particular and another. They would be as impossible to distinguish from one another as the millions of drops of water in the ocean would be indistinguishable from one another by the naked eye.
