Resistance is Futile: You mentioned that there is a lot of misinformation spread by former members of the Mormon Church. As a current member I'd therefore appreciate your input. Is it true that while Joseph Smith was already married to his first wife he had sex with several teenage women? Do you think he may have used his position of authority in his community to take advantage of young impressionable women in order to satisfy his own sexual impulses?
Well, this is way off topic, but no, Joseph Smith was married to one teenage girl and it was a marriage instituted by her father, one of our greatest prophets, Heber C. Kimball. Kimball loved Joseph and was a loyal friend. Accordingly, he wished to be bound to him, his family to Smith's family. The best way he could do that, he reasoned, is by arranging a marriage with his daughter. As far as we know, this marriage was never consumated. At the time, the daughter, Helen Mar Kimball, was taken back by this. One of our historians writes:
Though listed as fourteen at the time of her sealing to the Prophet, Helen Mar Kimball was nearly fifteen (see pp. 487, 499). She herself explains that her father took the initiative to arrange the marriage: "Having a great desire to be connected with the Prophet Joseph, he offered me to him; this I afterwards learned from the Prophet's own mouth" (quoted on p. 498). Helen was approaching eligibility, and a vital social life was opening up with possible proposals. Since some young women married at sixteen, Heber C. Kimball and the Prophet evidently arranged an early marriage to insure the desired personal and family relationships. However, Helen continued to live with her parents. Because Helen's circumstances were exceptional, there is every reason not to assume a sexual dimension in her sealing to Joseph Smith.
Helen later went to Salt Lake City with her family and wrote a story about her life. She gave no indication that a sexual relationship was entered into. She died in full faith and fellowship in the church, and when she wrote of Joseph, it was glowingly. As a people, we have endured a great deal of disinformation.
