It's taken more time to write about this reconstruction, because it is perhaps a more sensitive subject, and more complex, than any I have written before about Mormonism or Christianity, yes, even more so than Jesus or Joseph Smith (which might be an indication that something is off-kilter). The Salt Lake City based Latter-day Saints take the Book of Mormon very seriously as a holy text, as scripture revealed by God, similar to the Bible, and perhaps even more important than the Bible. The Book of Mormon is one thing that makes them unique, their own testament of the divinity of "Jesus Christ," which they believe is also evidence of the unique prophethood of Joseph Smith and the divinity of the church he organized as God's "true church." But I think the truth may be much more nuanced.
Bahá'u'lláh (1817-1892) was the founder of the Bahá'í Faith. In 1863 he announced that he was the fulfillment of a messianic prophecy given by the Báb in 1845. This prophetic call he said was made clear by a vision he had while imprisoned. The vision was of a heavenly Maiden who he said gave him his mission as a messenger of God, or Manifestation of God, as had been prophesied by the Báb.
Saint Teresa of Ávila (1515-1582) was a Spanish mystic, Carmelite nun, and was canonized a Roman Catholic saint by Pope Gregory XV. In her autobiography, The Life of St. Teresa of Jesus, she describes many of her ecstatic visions of the Divine which should ring a few bells for Latter-day Saints.
