A broad outline of factors initiated and associated with the Cause of the Báb

• The clarion-call addressed to the “concourse of kings and of the sons of kings,” marking the inception of a process which, accelerated by Bahá’u’lláh’s subsequent warnings to the entire company of the monarchs of East and West, was to produce so widespread a revolution in the fortunes of royalty, had been raised in the Qayyúmu’l-Asmá’.
• The “Order,” whose foundation the Promised One was to establish in the Kitáb-i-Aqdas, and the features of which the Center of the Covenant was to delineate in His Testament, and whose administrative framework the entire body of His followers are now erecting, had been categorically announced in the Persian Bayán.
• The laws which were designed, on the one hand, to abolish at a stroke the privileges and ceremonials, the ordinances and institutions of a superannuated Dispensation, and to bridge, on the other, the gap between an obsolete system and the institutions of a world-encompassing Order destined to supersede it, had been clearly formulated and proclaimed.
• The Covenant which, despite the determined assaults launched against it, succeeded, unlike all previous Dispensations, in preserving the integrity of the Faith of its Author, and in paving the way for the advent of the One Who was to be its Center and Object, had been firmly and irrevocably established.
• The light which, throughout successive periods, was to propagate itself gradually from its cradle as far as Vancouver in the West and the China Sea in the East, and to diffuse its radiance as far as Iceland in the North and the Tasman Sea in the South, had broken.
• The forces of darkness, at first confined to the concerted hostility of the civil and ecclesiastical powers of Shí‘ah Persia, gathering momentum, at a later stage, through the avowed and persistent opposition of the Caliph of Islám and the Sunní hierarchy in Turkey, and destined to culminate in the fierce antagonism of the sacerdotal orders associated with other and still more powerful religious systems, had launched their initial assault.
• The nucleus of the divinely ordained, world-embracing Community—a Community whose infant strength had already plucked asunder the fetters of Shí‘ah orthodoxy, and which was, with every expansion in the range of its fellowship, to seek and obtain a wider and still more significant recognition of its claims to be the world religion of the future, had been formed and was slowly crystallizing.
• And, lastly, the seed, endowed by the Hand of Omnipotence with such vast potentialities, though rudely trampled under foot and seemingly perished from the face of the earth, had, through this very process, been vouchsafed the opportunity to germinate and remanifest itself, in the shape of a still more compelling Revelation—a Revelation destined to blossom forth, in a later period into the flourishing institutions of a world-wide administrative System, and to ripen, in the Golden Age as yet unborn, into mighty agencies functioning in consonance with the principles of a world-unifying, world-redeeming Order.
