Let her [the church] give up the scientific education of her ministry. Let her assume the truth of her message and learn simply how it may be applied in detail to modern industrial and social conditions. Let her give up the laborious study of Greek and Hebrew. Let her abandon the scientific study of history to the men of the world. In a day of increased scientific interest, let the Church go on becoming less scientific. In a day of increased specialization, of renewed interest in philology and in history, of more rigorous scientific method, let the Church go on abandoning her Bible to her enemies. They will study it scientifically, rest assured, if the Church does not. Let her substitute sociology altogether for Hebrew, practical expertness for the proof of her gospel. Let her shorten the preparation of her ministry, let her permit it to be interrupted yet more and more by premature practical activity. By doing so she will win a straggler here and there. But her winnings will be but temporary. The great current of modern culture will sooner or later engulf her puny eddy. God will save her somehow–out of the depths. But the labor of centuries will have been swept away.
And now the Church is shrinking from the conflict. Driven from the spiritual realm by the current of modern thought, she is consoling herself with things about which there is no dispute. If she favors better housing for the poor, she need fear no contradiction…they will not fight her with argument. The twentieth century, in theory, is agreed on social betterment. But sin, and death, and salvation, and life, and God–about these things there is debate.
