The musical problem of the non-liturgic Church in America is, therefore, not one of creation, but of administration. Whatever the mission of the Church is to be in our national life, the opportunities of its music are not to be less than of old, but greater. It is evident that the notion of conviction of sin and sudden conversion is gradually losing the place which it formerly held in ecclesiastical theory, and is being supplemented, if not supplanted, by the notion of spiritual nurture. The Church is finding its permanent and comprehensive task in alliance with those forces that make for social regeneration; no longer to separate souls from the world and prepare them for a future state of existence, but to work to establish the kingdom of God here on earth; not denying the rights of the wholesome human instincts, but disciplining and refining them for fraternal service. In this broader sphere art, especially music, will be newly commissioned and her benign powers utilized with ever-increasing intelligence. The Church can never recover the old musical leadership which was wrested from her in the seventeenth and eighteenth centuries by the opera, the choral society, and the concert system, but in the twentieth she will find means of coöperating with these institutions for the general welfare. The council of Carthage in the fourth century laid this injunction upon church singers: “See that what thou singest with thy lips thou believest in thy heart; and what thou believest in thy heart thou dost exemplify in thy life.” This admonition can never lose its authority; back of true church music there must be faith. There comes, however, to supplement this ancient warning, the behest from modern culture that the music of the sanctuary shall adapt itself to the complex and changing conditions of modern life, and while it submits to the pure spirit of worship it shall grow continually in those qualities which make it worthy to be honored by the highest artistic taste. For among the venerable traditions of the Church, sanctioned by the wisdom of her rulers from the time of the fathers until now, is one which bids her cherish the genius of her children, and use the appliances of imagination and skill to add strength and grace to her habitations, beauty, dignity, and fitness to her ordinances of worship.
