The “shameful act of a fanatical and irresponsible Bábí” caused the Faith of the Báb to experience “the oppressive load of a fresh calamity, unprecedented in its gravity, disgraceful in its character, and devastating in its immediate consequences”

Such a severe ordeal the Faith of the Báb, still in the earliest stages of its infancy, was now beginning to experience. Maligned and hounded from the moment it was born, deprived in its earliest days of the sustaining strength of the majority of its leading supporters, stunned by the tragic and sudden removal of its Founder, reeling under the cruel blows it had successively sustained in Mázindarán, Tihrán, Nayríz and Zanján, a sorely persecuted Faith was about to be subjected through the shameful act of a fanatical and irresponsible Bábí, to a humiliation such as it had never before known. To the trials it had undergone was now added the oppressive load of a fresh calamity, unprecedented in its gravity, disgraceful in its character, and devastating in its immediate consequences.

“portentous, God-sent upheavals”: - “Invariably sudden, often unexpected, seemingly fatal to both its spirit and its life”

The Faith that had stirred a whole nation to its depth, for whose sake thousands of precious and heroic souls had been immolated and on whose altar He Who had been its Author had sacrificed His life, was now being subjected to the strain and stress of yet another crisis of extreme violence and far-reaching consequences. It was one of those periodic crises which, occurring throughout a whole century, succeeded in momentarily eclipsing the splendor of the Faith and in almost disrupting the structure of its organic institutions. Invariably sudden, often unexpected, seemingly fatal to both its spirit and its life, these inevitable manifestations of the mysterious evolution of a world Religion, intensely alive, challenging in its claims, revolutionizing in its tenets, struggling against overwhelming odds, have either been externally precipitated by the malice of its avowed antagonists or internally provoked by the unwisdom of its friends, the apostasy of its supporters, or the defection of some of the most highly placed amongst the kith and kin of its founders. No matter how disconcerting to the great mass of its loyal adherents, however much trumpeted by its adversaries as symptoms of its decline and impending dissolution, these admitted setbacks and reverses, from which it has time and again so tragically suffered, have, as we look back upon them, failed to arrest its march or impair its unity. Heavy indeed has been the toll which they exacted, unspeakable the agonies they engendered, widespread and paralyzing for a time the consternation they provoked. Yet, viewed in their proper perspective, each of them can be confidently pronounced a blessing in disguise, affording a providential means for the release of a fresh outpouring of celestial strength, a miraculous escape from imminent and still more dreadful calamities, an instrument for the fulfillment of age-old prophecies, an agency for the purification and revitalization of the life of the community, an impetus for the enlargement of its limits and the propagation of its influence, and a compelling evidence of the indestructibility of its cohesive strength. Sometimes at the height of the crisis itself, more often when the crisis was past, the significance of these trials has manifested itself to men’s eyes, and the necessity of such experiences has been demonstrated, far and wide and beyond the shadow of a doubt, to both friend and foe. Seldom, if indeed at any time, has the mystery underlying these portentous, God-sent upheavals remained undisclosed, or the profound purpose and meaning of their occurrence been left hidden from the minds of men.

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.
