All the rich treasures of the past are appropriated by Christianity--the moral culture of the Hebrew, the poetry and philosophy of Greece, the jurisprudence of Ancient Rome. All these--in so far as they are pure and good--are absorbed by Christianity, and ennobled and baptized by the Christian spirit. In Christian Europe poetry, philosophy, science flourished as they had never flourished in any preceding age, and they lay their richest tribute at the feet of Christ, the Divine King of the world. Nature, also, herself becomes more and more subject to man, and to the religion of the God-man. Science multiplies the means of diffusing knowledge and the facilities of intercourse among the nations of the earth. The discovery of the art of printing opens the Book of Life to the millions of our race. Space has been annihilated by railroads; by the help of steam continents are united; the electric telegraph is binding the nations in one. And now the genius of Christianity begins more signally to reveal itself as a power acting on the social life of man. The forms and conditions of his earthly lot are being wonderfully transformed and improved. Science is emancipating labor, and constantly overcoming the sources of human suffering. Hygienic science is preserving life and extending the term of human existence. Mankind is rising above the sphere of mere law, into the sphere of noble love. Philanthropic institutions are being daily multiplied, humanitarian and Christian enterprises most vigorously prosecuted, and a noble benevolence is rapidly supplanting the ignoble selfishness of former ages. Chalmers, Howard, Wilberforce, Hitchcock, Amos Lawrence, Elizabeth Fry, Florence Nightingale, Mrs. Gladstone, are representative men and women of the new age. Christian civilization is no longer the property of any one nation alone. Now it embraces in its purposes and plans the evangelization of all the nations of the earth. The world is now its field. The accumulated waves of light and power from Hebrew and Grecian and Roman civilizations, to which Christianity has added a new life and force, are destined to roll back a tide of blessing upon the remnants of those ancient nations, and sweep northward and southward-- "Till like a sea of glory, It spreads from pole to pole."
