Abstract: In the past decades much of the debate regarding Joseph Smith and plural marriage has focused on his motivation — whether libido or divine inspiration drove the process. Throughout these debates, a small group of observers and participants have maintained that Joseph did not practice polygamy at any time or that his polygamous sealings were nonsexual spiritual marriages. Rather than simply provide supportive evidence for Joseph Smith’s active involvement with plural marriage, this article examines the primary arguments advanced by monogamist proponents to show that important weaknesses exist in each line of reasoning.
