In the conduct of this twofold crusade the valiant warriors struggling in the name and for the Cause of Bahá'u'lláh must, of necessity, encounter stiff resistance, and suffer many a setback. Their own instincts, no less than the fury of conservative forces, the opposition of vested interests, and the objections of a corrupt and pleasure-seeking generation, must be reckoned with, resolutely resisted, and completely overcome. As their defensive measures for the impending struggle are organized and extended, storms of abuse and ridicule, and campaigns of condemnation and misrepresentation, may be unloosed against them. Their Faith, they may soon find, has been assaulted, their motives misconstrued, their aims defamed, their aspirations derided, their institutions scorned, their influence belittled, their authority undermined, and their Cause, at times, deserted by a few who will either be incapable of appreciating the nature of their ideals, or unwilling to bear the brunt of the mounting criticisms which such a contest is sure to involve. "Because of `Abdu'l-Bahá," the beloved Master has prophesied, "many a test will be visited upon you. Troubles will befall you, and suffering afflict you."
Let not, however, the invincible army of Bahá'u'lláh, who in the West, and at one of its potential storm-centers is to fight, in His name and for His sake, one of its fiercest and most glorious battles, be afraid of any criticism that might be directed against it. Let it not be deterred by any condemnation with which the tongue of the slanderer may seek to debase its motives. Let it not recoil before the threatening advance of the forces of fanaticism, of orthodoxy, of corruption, and of prejudice that may be leagued against it. The voice of criticism is a voice that indirectly reinforces the proclamation of its Cause. Unpopularity but serves to throw into greater relief the contrast between it and its adversaries, while ostracism is itself the magnetic power that must eventually win over to its camp the most vociferous and inveterate amongst its foes....
