December 19

Let not, however, the invincible army of Bahá'u'lláh, who in the West, and at one of its potential storm-centres 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....
