God maketh no distinction between the white and the black. If the hearts are pure both are acceptable unto Him. God is no respecter of persons on account of either color or race. All colors are acceptable to Him, be they white, black, or yellow. Inasmuch as all were created in the image of God, we must bring ourselves to realize that all embody divine possibilities. If you go into a garden and find all the flowers alike in form, species and color, the effect is wearisome to the eye. The garden is more beautiful when the flowers are many-colored and different; the variety lends charm and adornment. In a flock of doves some are white, some black, red, blue; yet they make no distinction among themselves. All are doves no matter what the color.
This variety in forms and colorings which is manifest in all the kingdoms is according to creative wisdom and has a divine purpose. Nevertheless, whether the creatures be all alike or all different should not be the cause of strife and quarreling among them. Especially why should man find cause for discord in the color or race of his fellow creature? No educated or illumined mind will allow that this differentiation and discord should exist or that there is any ground for it. Therefore, the whites should be just and kind to the blacks, who in turn should reflect an equal measure of appreciation and gratitude. Then will the world become as one great garden of flowering humanity, variegated and multicolored, rivaling each other only in the virtues and graces which are spiritual.
-‘Abdu’l-Baha, from a talk delivered on May 11, 1912 in New York.
