Joseph Smith's 1843 Revelation on Plural Marriage was the formal written articulation of a doctrine that reshaped his marriage and intensified disagreements within his inner circle. Recorded on July 12, 1843, and later known as Section 132 of the Doctrine and Covenants, it presented plural marriage as divinely authorized while placing a direct demand on Emma Smith to accept Joseph's marriages. Its immediate purpose and effect were bound up with that conflict: the text did not win Emma's assent, and it did not stop Joseph from taking additional wives.

Secrecy and the Nauvoo context

In Nauvoo, Joseph Smith had kept his plural marriages secret while waiting for what he regarded as the proper time to disclose the principle. The revelation was different from other doctrinal developments of the period: although formally recorded in 1843, it was kept secret and was not acknowledged until 1852, eight years after Joseph's death. That interval separated the document's creation from its public recognition and left the teaching circulating among a limited circle before it became an acknowledged church doctrine.

The revelation emerged during a period of major theological innovation. In Nauvoo, Joseph had introduced proxy baptism for the dead and the temple endowment, and taught that God had once been a man and that human beings could become gods. The plural-marriage revelation belonged to this same burst of religious teaching, but its secrecy and its direct implications for marriage made it especially contentious. It did not simply state an abstract principle: it addressed the household of Joseph and Emma by name and framed obedience to the principle as a matter of divine command.

That teaching accompanied a period in which Joseph married about forty women between 1840 and 1844. The revelation therefore came after plural marriages were already taking place, rather than initiating them from the beginning. Some women were shocked by what was asked of them; among them was fourteen-year-old Helen Mar Kimball, who later described being led to believe that her family's salvation depended on her agreement. Joseph married Helen in May 1843, two months before the revelation was recorded. Lucy Walker also married Joseph that May, after a family bereavement and a period in which Joseph had taken her and several siblings into his household. These marriages show the circumstances surrounding the document, while the text supplied a formal religious rationale for the practice.

Emma Smith and the making of the revelation

Emma had been married to Joseph since 1827 and opposed his plural marriages. By 1844, people in Joseph's inner circle had learned of his plural relationships, and some had seen the revelation before it was publicly acknowledged. Emma's opposition was not peripheral to the text's formation. The account describes the revelation as having been prompted, at least in its original intent, by Joseph's wish to persuade her to accept his plural wives while forbidding her from seeking sexual relationships outside their marriage.

On the morning of July 12, Hyrum Smith urged Joseph to write down the revelation, believing he could use it to persuade Emma. Joseph agreed, and his secretary recorded the text. Its repeated naming of Emma made the personal stakes explicit: it instructed her to remain with Joseph and threatened divine destruction if she refused the commandment. The document thus joined a general rule about plural marriage to a particular demand on the first wife, presenting her compliance as an obligation rather than a matter for mutual agreement.

After Joseph finished dictating, Hyrum delivered the ten-page document to Emma. She rejected it and remained unwilling to accept Joseph's marriages. Hyrum reported that she was bitter and angry, and that she did not believe the revelation. Her response did not alter Joseph's conduct: he continued taking wives, but made no further effort to secure her consent. The encounter exposed a central contradiction in the document's domestic authority. It claimed divine force over Emma while failing to persuade the person whose obedience it specifically sought.

The doctrine's terms and unequal obligations

The revelation justified a man who married a virgin and then took another wife under the stated law, declaring that such marriages did not constitute adultery. It extended that logic even to a man with ten wives, treating them as given to him under the commandment. By contrast, it assigned a grave consequence to a wife who, after being married, was with another man. The text therefore established a sharply unequal system: a man's plurality of wives could be authorized, while a woman's sexual relationship with another man was condemned.

This difference was not incidental to the revelation's argument. Its claim of divine authorization depended on treating women as wives given to a man under the law, while placing the obligation to remain faithful on the woman. In Emma's case, the text demanded that she cleave to Joseph alone even as it defended his right to marry other women. Its language translated a disputed marital practice into a question of obedience to God, and made resistance appear not simply as disagreement with a husband but as refusal of a divine command.

Reception and consequences

Emma's refusal did not end Joseph's plural marriages, and the revelation did not restore agreement within the household. It instead sharpened an existing divide between Joseph and those who opposed the doctrine. William Law, a close friend of Joseph and his second counselor, supported Emma and urged Joseph in January 1844 to renounce the revelation. Joseph told Law that he could not withdraw a commandment he believed God had given him. Their disagreement over plural marriage strained their friendship, which was later severed amid further conflict over Joseph's conduct.

The document's immediate history is therefore one of contested authority: Joseph treated the principle as binding because he understood it to be divinely commanded; Emma rejected the text's demand; and Hyrum's attempt to mediate failed. Its later public acknowledgment in 1852 gave formal recognition to a revelation that had remained secret during Joseph's life. The episode is significant not only for establishing plural marriage as a religious principle, but also for showing how that principle was written into scripture through a private marital dispute—and how the document's claim of heavenly authority could not resolve the human opposition it was meant to overcome.
