"Primitive religions consisted mainly in the worship of the powers of nature. ...the essential thing in religion was not morality, but the ceremonial method of placating the god, securing his gifts, and ascertaining his wishes. He might even be pleased best by immoral actions, by the immolation of human victims, by the sacrifice of woman's chastity, or by the burning of the first born."

“The religious ideal of Israel was the theocracy. But the theocracy meant the complete penetration of the national life by religious morality. It meant politics in the name of God.”

“The prophets... interpreted past history, shaped present history, and foretold future history on the basis of the conviction that God rules with righteousness in the affairs of nations, and that only what is just, and not what is expedient and profitable, shall endure.”

“We are to-day in the midst of a revolutionary epoch fully as thorough as that of the Renaissance and Reformation. It is accompanied by a reinterpretation of nature and of history. The social movement has helped to create the modern study of history. Where we used to see a panorama of wars and strutting kings and court harlots, we now see the struggle of the people to wrest a living from nature and to shake off their oppressors. The new present has created a new past. The French Revolution was the birth of modern democracy, and also of the modern school of history.”

“The sympathy of the prophets, even of the most aristocratic among them, was entirely on the side of the poorer classes. ...The edge of their invectives was turned against the land-hunger of the landed aristocracy who "joined house to house and laid field to field," till a country of sturdy peasants was turned into a series of great estates; against the capitalistic ruthlessness that "sold the righteous for silver and the needy for a pair of shoes," thrusting the poor free-man into slavery to collect a trifling debt; against the venality of the judges who took bribes and had a double standard of law for the rich and the poor.”

“Whoever uncouples the religious and the social life has not understood Jesus. Whoever sets any bounds for the reconstructive power of the religious life over the social relations and institutions of men, to that extent denies the faith of the Master.”

“The social revolution has been slow in reaching our country. We have been exempt, not because we had solved the problems, but because we had not yet confronted them.”
