"Some of these associates alleged that Smith tried to marry their wives. About eight of Smith's wives were also married to other men (four were Mormon men in good standing, who in a few cases acted as a witness in Smith's marriage to his wife) at the time they married Smith. Typically, these women continued to live with their first husband, not Smith. Some accounts say Smith may have had sexual relations with one wife, who later in her life stated that he fathered children by one or two of his wives, although the reliability of these sources is disputed."
This is a drop in the bucket of the man who claimed to be superior to Jesus. However Jesus knew no sin, and his followers still worship him to this day.
