…all mankind belong to one family, all are one progeny of Adam, all are servants of the one God, all have been created by one God, God is the provider for all, God nurtures all, all are submerged in the sea of the mercy and grace of God, and God is kind to all.
All humankind share in common the intellectual and spiritual faculties of a created endowment. All are equally subject to the various exigencies of human life, and are similarly employed in acquiring the means of earthly livelihood. In every respect from the viewpoint of creation all stand upon the same footing -- all have the same requirements, -- all are seeking the happiness and comfort of earthly conditions; that is to say, the things they share in common are numerous and manifest. (‘Abdu’l-Baha, ‘Baha'i Scriptures’)
