What Latter-day Saints today call the Temple Endowment was first given by the prophet Joseph Smith in 1842, two years prior to his death, to a small group of nine of his trusted associates in Nauvoo, Illinois. It was a key piece of the larger vibrant temple liturgy then developing in Nauvoo. But where did this temple endowment come from? What was its relationship to the prophet’s previous revelations? And what, if anything, was its relationship to masonry which Joseph Smith had joined only two months before administering that first endowment to his nine friends (who, by the way, were all masons as well)? 
In this episode of Church History Matters, Casey and Scott dig into the details of what we know (or think we know) about the origins of the Temple endowment ritual. They discuss several of what they believe are primary source materials the Prophet Joseph drew from as he formulated this important ordinance under inspiration. And they also offer a Nauvoo angle to the meaning of the word “Restoration.”
