The ST. LOUIS BULLETIN publishes Martha Brotherton's account of her invitation to enter into polygamy in Nauvoo. She tells how she was privately approached by Brigham Young and asked "were it lawful and right -- could [you] accept of me for your husband and companion?" Young stated that "Brother Joseph has had a revelation from God that it is lawful and right for a man to have two wives; for as it was in the days of Abraham, so it shall be in these last days -- if you will accept of me, I will take you straight to the celestial kingdom." Brotherton reports that when she hesitated, Young left the room and returned ten minutes later with Smith. "Well, Martha," she reports the prophet as saying, "just go ahead, and do as Brigham wants you to.- I know that this is lawful and right before God.- I have the keys of the kingdom, and whatever I bind on earth is bound in heaven, and whatever I loose on earth is loosed in heaven." Martha begs for time to consider the offer, then left for St. Louis, where she publishes her story.
