" “To which nationality do you belong?” the answer will be, “To the nationality of humanity. I am living under the shadow of Bahá’u’lláh." "

"A much greater difficulty confronts us today when we endeavor to establish unity between the Orient and the Occident. Bahá’u’lláh through the power of heaven has brought the East and the West together. Erelong we shall know that they have been cemented by the power of God. The oneness of the kingdom of humanity will supplant the banner of conquest, and all communities of the earth will gather under its protection. No nation with separate and restricted boundaries—such as Persia, for instance—will exist. The United States of America will be known only as a name. Germany, France, England, Turkey, Arabia—all these various nations will be welded together in unity. When the people of the future are asked, “To which nationality do you belong?” the answer will be, “To the nationality of humanity. I am living under the shadow of Bahá’u’lláh. I am the servant of Bahá’u’lláh. I belong to the army of the Most Great Peace.” The people of the future will not say, “I belong to the nation of England, France or Persia”; for all of them will be citizens of a universal nationality—the one family, the one country, the one world of humanity—and then these wars, hatreds and strifes will pass away."
