The “oneness of humanity is the primary foundation of” the virtues of the human world

Consider the virtues of the human world and realize that the oneness of humanity is the primary foundation of them all. Read the Gospel and the other Holy Books. You will find their fundamentals are one and the same. Therefore, unity is the essential truth of religion and, when so understood, embraces all the virtues of the human world. (‘Abdu’l-Baha, The Promulgation of Universal Peace, p. 32)
