I don't know if this topic was posted before. Anyway, it refers to the possibility of a future woman as Manifestation of God. I will not comment, I just want to quote this quotation of Bahá'u'lláh, and then people can get their own conclusions.
Know thou moreover that in the Day of Revelation were He to pronounce one of the leaves to be the manifestation of all His excellent titles, unto no one is given the right to utter why or wherefore, and should one do so he would be regarded as a disbeliever in God and be numbered with such as have repudiated His Truth.
