It is certain that the greatest of instrumentalities for achieving the advancement and the glory of man, the supreme agency for the enlightenment and the redemption of the world, is love and fellowship and unity among all the members of the human race. Nothing can be effected in the world, not even conceivably, without unity and agreement, and the perfect means for engendering fellowship and union is true religion.
