Throughout the animal kingdom we do not find the creatures
separated because of color. They recognize unity of species and oneness of
kind. If we do not find color distinction drawn in a kingdom of lower
intelligence and reason, how can it be justified among human beings, especially
when we know that all have come from the same source and belong to the same
household? In origin and intention of creation mankind is one. Distinctions of
race and color have arisen afterward. (‘Abdu’l-Baha, quoted by Shoghi Effendi
in ‘The Advent of Divine Justice’)
