There are, however, other church forces in the community—­organizations fostered and supported by the material and moral enthusiasm of the members of the church.  Some of these organizations have been frankly formed for the purpose of assisting the church in some special field of religious education.  This is essentially true of such boy organizations as the Knights of King Arthur, Knights of St. Paul, Knights of the Holy Grail, and the Boys’ Brigade.  It is essentially true, also, of the Young Men’s Christian Association.  The first of these—­the boy organizations—­constitutes a method which is at the disposal of the church.  The second—­the Christian Association—­has grown to be a mighty operating force, with hundreds of employed officers and millions of dollars of property.  Save for the fact that church members compose the directorates, it is independent of the church.  With this and other organizations what can the church’s relationship be?  The seeming answer would be cooperation—­a glad working together for the general betterment of the community itself by tried and approved plans.  However, a new condition has arisen, which offers more than general cooperation between the Church and these organizations for the teen age boy.  Until recently the church school had no clear-cut method for working with the teen age lad, while the boy organizations referred to had such a method, and the Young Men’s Christian Association, after years of work, has a force of more or less experienced experts in boy life in its employ.  The methods of these boy organizations and the boy experts of the Young Men’s Christian Association must have a field of operation, and the best field, of course, is that of the church school, where boys should be found.  The Young Men’s Christian Association, in its own building, touches but a minute fraction of the boy life of the city in which it operates, and, to touch the city boy life, must get out of its building.  It then has a choice of fields, Public Playground, Public School, or Community Betterment.  If, however, it is true to the principle of its founding—­to be an arm of the Church among young men—­that which it attempts to do should be tied up to the Church, or, in the case of teen age boys, to the church school.  To accomplish the latter, what shall the procedure be?  Shall the Young Men’s Christian Association win the boy, and then deliver him, saved for service, to the Church, or shall the Young Men’s Christian Association work with the Church as part of the Church inside the church school?  Common sense would say both ways, and all other ways possible, just so the boy stands saved and in the Church for service.  And this is as it should be, and the employed experts of the Young Men’s Christian Association should render service to the Church, both within and without the Church—­and this service may be through method, or organization, or both.  At all times the weakness of the Church should be the Association’s opportunity to help the Church realize herself, and this can best be accomplished by the constructive suggestion that works its way out on the inside of the organization.  Little help comes from battering a wall on the outside.  At least it does not help the house inside any.  Cooperation, then, must be understood as the internal assistance given the Church herself to realize the need and the plan to meet it.
