It is true that Bahá’ís are not pacifists since we uphold the use of force in the service of justice and upholding law. But we do not believe that war is ever necessary and its abolition is one of the essential purposes and brightest promises of Bahá’u’lláh’s revelation. His specific command to the kings of the earth is: “Should any one among you take up arms against another, rise ye all against him, for this is naught but manifest justice.” (Tablet to Queen Victoria, “The Proclamation of Bahá’u’lláh”, p. 13) The beloved Guardian has explained that the unity of mankind implies the establishment of a world commonwealth, a world federal system, “...liberated from the curse of war and its miseries in which Force is made the servant of Justice...” whose world executive “backed by an international Force,...will safeguard the organic unity of the whole commonwealth.” This is obviously not war but the maintenance of law and order on a world scale. Warfare is the ultimate tragedy of disunity among nations where no international authority exists powerful enough to restrain them from pursuing their own limited interests. Bahá’ís therefore ask to serve their countries in non-combatant ways during such fighting; they will doubtless serve in such an international Force as Bahá’u’lláh envisions, whenever it comes into being. (11 September 1984 to an individual believer) [75] 76: Bahá’u’lláh’s principal mission in appearing at this time in human history Bahá’u’lláh’s principal mission in appearing at this time in human history is the realization of the oneness of mankind and the establishment of peace among the nations; therefore, all the forces which are focused on accomplishing these ends are influenced by His Revelation. We know, however, that peace will come in stages. First, there will come the Lesser Peace, when the unity of nations will be achieved, then gradually the Most Great Peace—the spiritual as well as social and political unity of mankind, when the Bahá’í World Commonwealth, operating in strict accordance with the laws and ordinances of the Most Holy Book of the Bahá’í Revelation, will have been established through the efforts of the Bahá’ís. As to the Lesser Peace, Shoghi Effendi has explained that this will initially be a political unity arrived at by decision of the governments of various nations; it will not be established by direct action of the Bahá’í community. This does not mean, however, that the Bahá’ís are standing aside and waiting for the Lesser Peace to come before they do something about the peace of mankind. Indeed, by promoting the principles of the Faith, which are indispensable to the maintenance of peace, and by fashioning the instruments of the Bahá’í Administrative Order, which we are told by the beloved Guardian is the pattern for future society, the Bahá’ís are constantly engaged in laying the groundwork for a permanent peace, the Most Great Peace being their ultimate goal.
