And now, one of the greatest and most fundamental principles of the Cause of God is to shun and avoid entirely the Covenant-breakers, for they will utterly destroy the Cause of God, exterminate His Law and render of no account all efforts exerted in the past. O friends! It behooveth you to call to mind with tenderness the trials of His Holiness, the Exalted One, and show your fidelity to the Ever-Blest Beauty. The utmost endeavor must be exerted lest all these woes, trials and afflictions, all this pure and sacred blood that hath been shed so profusely in the Path of God, may prove to be in vain. Ye know well what the hands of the Center of Sedition, Mírzá Muhammad ‘Alí, and his associates have wrought. Among his doings, one of them is the corruption of the Sacred Text whereof ye are all aware, the Lord be praised, and know that it is evident, proven and confirmed by the testimony of his brother, Mírzá Badí’u’lláh, whose confession is written in his own handwriting, beareth his seal, is printed and spread abroad. This is but one of his misdeeds. Can a transgression be imagined more glaring than this, the interpolation of the Holy Text? Nay, by the righteousness of the Lord! His transgressions are writ and recorded in a leaflet by itself. Please God, ye will peruse it.
