To the spiritual practitioner, moreover, will have come increased skill in that most difficult of all arts, personal work. He will have had daily hospital training in ministering to the souls of men. He will speak their language, even their lingo, rather than what is to multitudes the unintelligible patois of the seminary Canaan. He will know not only his own theories but their difficulties and experiences in regard to a belief in immortality and the practice of prayer. Like Jesus at the well, he will have learned the method and value of gaining a point of contact in teaching. Formerly it was easy to discourse from the pulpit concerning the being and nature of God and to champion theories of the atonement. The prophet of the regiment will have learned what is far more difficult and more necessary--to persuade a man to follow the teaching and to practice the friendship of Jesus. That is his task, and he will have become efficient in its accomplishment--so to bring modern prodigals to themselves that they loathe the far country, and arise, and go home to their Father's house. Another gain will be that of a deeper appreciation of denominational coöperation and an enlarged scope for the practice of it. Sectarian rivalries and ecclesiastical trivialities vanish in the trenches. Man-made walls between Christian brethren are crumbling. Petty partisanship becomes first ridiculous and then wicked in the light of the universal church's ambition. "We need a standard so universal," writes H. G. Wells, "that the plate-layer may say to the barrister or the duchess, or the Red Indian to the Limehouse sailor, or the Anzac soldier to the Sinn Feiner or the Chinaman, 'What are we two doing for it?' And to fill the place of that 'It' no other idea is great enough or commanding enough, but only the world Kingdom of God." The same buildings are now serving congregations of Jews, Protestants and Romanists. Instant calls come when rabbis, priests, rectors, and representatives of every hue in the rainbow of Protestantism minister to men of other creeds and of no creed. Partisan politics in the field of pure religion are seen to be essentially irreligious; and chaplains of every ilk and kirk are working together like "Bill" and "Alf," two cockney soldiers, one of whom had lost a right arm and the other a left. They always sat side by side at the C. C. S. concerts "so as we can have a clap," as "Alf" put it. "Bill puts 'is 'and out, an' I smacks it with mine." Such men cannot come home and take part in the heresy trials and ecclesiastical hecklings of men whom at heart they recognize as Christian brethren. It is perfectly safe to prophesy that there will be more of church unity, and possibly more of uniformity, so far as this is desirable, when these apostles of hundreds of churches come home from the war.
