From the introductory.... As students in this Summer's School of Theology you have attended a series of lectures on fluctuations in religious interest, on the frequent occurrence of religious declines followed soon by recoveries or regenerations both within and without the churches, on the frequent attempts to bring the prevalent religious doctrines into harmony with new tendencies in the intellectual world, on the constant struggle between conservatism and liberalism in existing churches and between idealism and materialism in society at large, on the effects of popu lar education and the modern spirit of inquiry on religious doctrines and organizations, on the changed views of thinking people concerning the nature of the world and of man, on the increase of knowledge as affecting religion, and on the new ideas of God. You have also listened to lectures on psychotherapy, a new development of an ancient tendency to mix religion with medicine, and on the theory of evolution, a modern scientific doctrine which within fifty years has profoundly modified the religious conceptions and expectations of many thinking people. You have heard, too, how the new ideas of democracy and social progress have modified and ought to modify not only the actual work done by the churches, but the whole conception of the functions of churches.
