We understand that if Theology in general means the systematised interpretation of Divine truth, Christian Theology means the systematised interpretation of the redemptive revelation of God in Christ. That is its subject, and its method is the exposition of Holy Scripture. Natural Theology differs from Christian Theology both in subject-matter and in method. Its subject is the revelation of God in Nature and in the world of man, and its method is the exposition of that revelation in the light of human reason and conscience. Of course this is not to say that there cannot be a Christian Natural Theology. That would be to prejudge an issue which is sharply dividing Protestant theological thought on the Continent at the present time and which is the occasion of this paper. But I think that, without prejudging that issue, it can be said that if the exposition of Nature and man's world be made in the light and under the authority of the Christian revelation, then, in a not unimportant sense, Natural Theology loses its distinctive character. For though, in that case, it continue to interrogate Nature and Man, it derives its decisive answers from the revelation in Christ, and thus becomes distinctively Christian and Scriptural.
