I write this little book in order to help towards an answer to the question, How is it with the Christian religion at the front? With the flower of British manhood massed in the Army this and like questions are bound to arise—How is it with the men? Where are they religiously? What do they want? What will they need when they return? and so forth. There never has been such an opportunity of taking a comparative view of British Christianity and of framing answers to such questions. Perhaps those who are working as chaplains at the front are especially challenged to attempt these tasks. Their answer must not be loose or sentimental. There is a danger of that. The emotions aroused by the war may encourage sentimental verdicts. That may be the reason why a good many ideas which are current at home about religion at the front, are a good distance removed from reality.
