" ... it is clear and evident that the greatest power in the human world is the love of God."

"It is clear that human realities differ one from another, that opinions and perceptions vary, and that this divergence of thoughts, opinions, understandings, and sentiments among individuals is an essential requirement. For differences of degree in creation are among the essential requirements of existence, which is resolved into countless forms. We stand therefore in need of a universal power which can prevail over the thoughts, opinions, and sentiments of all, which can annul these divisions and bring all souls under the sway of the principle of the oneness of humanity. And it is clear and evident that the greatest power in the human world is the love of God. It gathers divers peoples under the shade of the tabernacle of oneness and fosters the greatest love and fellowship among hostile and contending peoples and nations."
