"The ideal of this brotherhood is to draw angels and men, two branches of the infinite family of God, into close cooperation. The chief purpose of such cooperation is to uplift the human race. To this end the angels, on their side, are ready to participate as closely as possible in every department of human life and in every human activity that holds cooperation in view. Those members of the human race who will throw open heart and mind to their brethren of the other sphere, will find an immediate response, and a gradually increasing conviction of its reality."
