Retributive calamity... for turning a deaf ear to the Voice of God’s Messenger

The violent derangement of the world’s equilibrium; the trembling that will seize the limbs of mankind; the radical transformation of human society; the rolling up of the present-day Order; the fundamental changes affecting the structure of government; the weakening of the pillars of religion; the rise of dictatorships; the spread of tyranny; the fall of monarchies; the decline of ecclesiastical institutions; the increase of anarchy and chaos; the extension and consolidation of the Movement of the Left; the fanning into flame of the smouldering fire of racial strife; the development of infernal engines of war; the burning of cities; the contamination of the atmosphere of the earth these stand out as the signs and portents that must either herald or accompany the retributive calamity which, as decreed by Him Who is the Judge and Redeemer of mankind, must, sooner or later, afflict a society which, for the most part, and for over a century, has turned a deaf ear to the Voice of God’s Messenger in this day a calamity which must purge the human race of the dross of its age-long corruptions, and weld its component parts into a firmly-knit world-embracing Fellowship.

-Shoghi Effendi
