A Review of Samuel M. Brown's First Principles and Ordinances: The Fourth Article of Faith in Light of the Temple, Provo, UT: Neal A. Maxwell Institute, 2014. 167 pp., index.In his most recent book, First Principles and Ordinances: The Fourth Article of Faith in Light of the Temple (hereafter First Principles), Samuel M. Brown observes that "the Plan of Salvation [is] fundamentally about relationships." This recognition drove the prophet Joseph Smith and early Church members to "forge communities [of saints] that could endure beyond the veil of death" (151). Today, the importance of the temple and its ordinances to family relationships, eternal in their design, are clear to most Latter-day Saints. However, our collective view of the meaning of the principles and ordinances that precede the temple -- and lead us to it -- is somewhat murkier. Brown demonstrates that what Latter-day Saints sometimes perfunctorily regard merely as "the first principles and ordinances of the gospel" (Articles of Faith 1:4) are -- every bit as much as the temple itself is -- about relationships. In fact, one cannot fully contextualize the temple and its ordinances unless one understands this aspect of the first principles and ordinances of the gospel.
