Doctrine and Covenants 132 is the revelation on plural marriage dictated by Joseph Smith in 1843. Shared in secret during his lifetime and later canonized in 1879, it became one of the most consequential and controversial texts in Latter-day Saint history. The revelation introduced the sealing of marriages for eternity, provided the theological foundation for polygamy, and continues to influence Church teachings about family and exaltation today. In this interview, scholar William V. Smith explores D&C 132’s origins and lasting impact.
