essence of Baha’u’llah’s World Order is the unity of the human race.  ’O ye children of men’, He writes, ’the fundamental purpose animating the Faith of God and His Religion is to safeguard the interests and promote the unity of the human race...’  And He warns, ’The well-being of mankind, its peace and security, are unattainable unless and until its unity is firmly established.’  The achievement of this unity is Baha’u’llah’s declared mission and the aim of all Baha’i activity.  Its outline and structure are indicated in the following passage from the writings of Shoghi Effendi, great-grandson of Baha’u’llah and Guardian of the Baha’i Faith: 

The unity of the human race, as envisaged by Baha’u’llah, implies the establishment of a world commonwealth in which all nations, races, creeds and classes are closely and permanently united, and in which the autonomy of its state members and personal freedom and initiative of the individuals that compose them are definitely and completely safeguarded.  This commonwealth must, as far as we can visualize it, consist of a world legislature, whose members will, as the trustees of the whole of mankind, ultimately control the entire resources of all the component nations, and will enact such laws as shall be required to regulate the life, satisfy the needs and adjust the relationships of all races and peoples.  A world executive, backed by an international Force, will carry out the decisions arrived at, and apply the laws enacted by, this world legislature, and will safeguard the organic unity of the whole commonwealth.  A world tribunal will adjudicate and deliver its compulsory and final verdict in all and any disputes that may arise between the various elements constituting this universal system.  A mechanism of world inter-communication will be devised, embracing the whole planet, freed from national hinderances and restrictions, and functioning with marvellous swiftness and perfect regularity.  A world metropolis will act as the nerve centre of a world civilization, the focus towards which the unifying forces of life will converge and from which its energizing influences will radiate.  A world language will either be invented or chosen from among the existing languages and will be taught in the schools of all the federated nations as an auxiliary to their mother tongue.  A world script, a world literature, a uniform and universal system of currency, of weights and measures, will simplify and facilitate intercourse and understanding among the nations and races of mankind.  In such a world society, science and religion, the two most potent forces in human life, will be reconciled, will co-operate, and will harmoniously develop.  The press will, under such a system, while giving full scope to the expression of the diversified views and convictions of mankind, cease to be mischievously manipulated by vested interests, whether private or public, and will be liberated from the influence of contending governments
