Theology was once the great intellectual interest of thoughtful men. It explained their religious experience, justified their faith, and gave them intellectual satisfaction. It earned and deserved the title of “the queen of the sciences.” It has now fallen upon evil days. It is depreciated and neglected. Its foes are many; and its friends, even in the Church, are not numerous. The explanation for this situation of theology may be found in the immediate practical interests of life, the new thought-world in which men now live, and also in the inadequacy of the theology once current to meet the intellectual and moral demands of modern men.

Explanation, however, is not justification. There is the same reason for theology today as yesterday. The facts of religious experience remain essentially the same, and they still demand interpretation. The faith of the soul must be maintained in a world which challenges its right to be, and against hostile systems of thought. The interpretation and vindication of religion are more needed today than ever before. The incompetence of old theologies is no reason for doing without theology. If we are true to the demands of religion, we shall be constrained to provide some theology. The new attempts at securing an adequate theology must, however, be thorough and courageous. The great need now is the discovery of some principle by which we can interpret the facts of religious experience and arrive at a reasoned insight into the meaning of man, the world, and God. It is the conviction of the writer that the religious thinker has given him in Christ this interpretative principle, and that his great tasks can be achieved by the use of this principle.
