And among the teachings of His Holiness Bahá’u’lláh is the oneness of the world of humanity; that all human beings are the sheep of God and He is the kind Shepherd. This Shepherd is kind to all the sheep, because He created them all, trained them, provided for them and protected them. There is no doubt that the Shepherd is kind to all the sheep; and should there be among these sheep ignorant ones, they must be educated; if there be children, they must be trained until they reach maturity; if there be sick ones, they must be healed. There must be no hatred and enmity, for as by a kind physician these ignorant, sick ones should be treated. And among the teachings of His Holiness Bahá’u’lláh is that religion must be the cause of fellowship and love. If it becomes the cause of estrangement, then it is not needed, for religion is like a remedy: if it aggravates the disease, then it becomes unnecessary. And among the teachings of Bahá’u’lláh is that religious, racial, political, economic and patriotic prejudices destroy the edifice of humanity. As long as these prejudices prevail, the world of humanity will have no rest. For a period of six thousand years history informs us about the world of humanity. During these six thousand years the world of humanity has not been free from war, strife, murder and bloodthirstiness. In every period war has been waged in one country or another, and that war was due to either religious prejudice, racial prejudice, political prejudice or patriotic prejudice. It has, therefore, been ascertained and proved that all prejudices are destructive of the human edifice. As long as these prejudices persist, the struggle for existence must remain dominant, and bloodthirstiness and rapacity continue. Therefore, even as was the case in the past, the world of humanity cannot be saved from the darkness of nature, and cannot attain illumination, except through the abandonment of prejudices and the acquisition of the morals of the Kingdom.... And among the teachings of His Holiness Bahá’u’lláh is the origination of one language that may be spread universally among the people. This teaching was revealed from the pen of Bahá’u’lláh in order that this universal language may eliminate misunderstandings from among mankind. And among the teachings of His Holiness Bahá’u’lláh is the equality of women and men. The world of humanity has two wings— one is woman and the other man. Not until both wings are equally developed can the bird fly. Should one wing remain weak, flight is impossible. Not until the world of woman becomes equal to the world of man in the acquisition of virtues and perfections, can success and prosperity be attained as they ought to be.
