We have only to refer to the warnings uttered by 'Abdu'l-Bahá in order to realize the extent and character of the forces that are destined to contest with God's holy Faith....
Stupendous as is the struggle which His words foreshadow, they also testify to the complete victory which the upholders of the Greatest Name are destined eventually to achieve. Peoples, nations, adherents of divers faiths, will jointly and successively arise to shatter its unity, to sap its force, and to degrade its holy name. They will assail not only the spirit which it inculcates, but the administration which is the channel, the instrument, the embodiment of that spirit. For as the authority with which Bahá'u'lláh has invested the future Bahá'í Commonwealth becomes more and more apparent, the fiercer shall be the challenge which from every quarter will be thrown at the verities it enshrines. (Shoghi Effendi, From a letter dated 21 March 1930 to the Bahá'ís of the West, published in "The World Order of Bahá'u'lláh: Selected Letters"; The Compilation of Compilations, vol. II, Opposition)
