I am however assured and sustained by the conviction, never dimmed in my mind, that whatsoever comes to pass in the Cause of God, however disquieting in its immediate effects, is fraught with infinite Wisdom and tends ultimately to promote its interests in the world. Indeed, our experiences of the distant past, as well as of recent events, are too numerous and varied to permit of any misgiving or doubt as to the truth of this basic principle — a principle which throughout the vicissitudes of our sacred mission in this world we must never disregard or forget.
Shoghi Effendi, Bahá’í Administration, p. 27
These challenging criticisms, whether or not dictated by malice, cannot but serve to galvanize the souls of its ardent supporters, and to consolidate the ranks of its faithful promoters. They will purge the Faith from those pernicious elements whose continued association with the believers tends to discredit the fair name of the Cause, and to tarnish the purity of its spirit. We should welcome, therefore, not only the open attacks which its avowed enemies persistently launch persistently launch against it, but should also view as a blessing in disguise every storm of mischief with which they who apostatize their faith or claim to be its faithful exponents assail it from time to time. Instead of undermining the Faith, such assaults, both from within and from without, reinforce its foundations, and excite the intensity of its flame. . . .
Shoghi Effendi, Extracts from the US Bahá’í News (Ocean)
This is the result of the slanderer’s work: to be the cause of guiding men to a discovery of the truth.
We know that all the falsehoods spread about Christ and His apostles and all the books written against Him, only led the people to inquire into His doctrine; then, having seen the beauty and inhaled the fragrance, they walked evermore amidst the roses and the fruits of that celestial garden.
Abdu’l-Baha, Paris Talks, p. 104
As opposition to the Faith, from whatever source it may spring, whatever form it may assume, however violent its outbursts, is admittedly the motive-power that galvanizes on the one hand, the souls of its valiant defenders, and taps for them, on the other, fresh springs of that Divine and inexhaustible Energy, we who are called upon to represent, defend and promote its interests, should, far from regarding any manifestation of hostility as an evidence of the weakening of the pillars of the Faith, acclaim it as both a God-sent gift and a God-sent opportunity which, if we remain undaunted, we can utilize for the furtherance of His Faith and the routing and complete elimination of its adversaries.
…Fierce and relentless will be the opposition which this crystallization and emergence must provoke. The alarm it must and will awaken, the envy it will certainly arouse, the misrepresentations to which it will remorselessly be subjected, the setbacks it must, sooner or later, sustain, the commotions to which it must eventually give rise, the fruits it must in the end garner, the blessings it must inevitably bestow and the glorious, the Golden Age, it must irresistibly usher in, are just beginning to be faintly perceived, and will, as the old order crumbles beneath the weight of so stupendous a Revelation, become increasingly apparent and arresting.
Shoghi Effendi, Messages to America, p. 51-2
Indeed, the attacks and the obstructiveness of the ignorant but cause the Word of God to be exalted, and spread His signs and tokens far and wide. Were it not for this opposition by the disdainful, this obduracy of the slanderers, this shouting from the pulpits, this crying and wailing of great and small alike, these accusations of unbelief levelled by the ignorant, this uproar from the foolish — how could news of the advent of the Primal Point and the bright dawning of the Day-star of Baha ever have reached to east and west?
…All these blessings and bestowals, the very means of proclaiming the Faith, have come about through the scorn of the ignorant, the opposition of the foolish, the stubbornness of the dull-witted, the violence of the aggressor. Had it not been for these things, the news of the Báb’s advent would not, to this day, have reached even into lands hard by. Wherefore we should never grieve over the blindness of the unwitting, the attacks of the foolish, the hostility of the low and base, the heedlessness of the divines, the charges of infidelity brought against us by the empty of mind.
‘Abdu’l-Bahá, Selections from the Writings of ‘Abdu’l-Bahá, sec. 195, pp. 234-36
His [Shoghi Effendi] fears are rather for those friends who, due to their insufficient realization of the divine power that mysteriously operates in the Faith, are prone to look at such developments as constituting the death-knell of the Cause. In his communications to the … friends during the last few weeks he has always stressed the fact, and he wishes you to do the same in all your conversations and correspondence with them, that the Cause is bound sooner or later to suffer from all kinds of attacks and persecutions, that these in fact constitute the life-blood of its institutions, and as such constitute an inseparable and intrinsic part of its development and growth. Trials and tribulations, as Bahá’u'lláh says, are the oil that feed the lamp of the Cause, and are indeed blessings in disguise. The friends should therefore be confident that all these attacks to which the Cause is now subjected … are a necessary part of the development of the Cause, and that their outcome would be beneficial to its best interests.
