The Book of Mormon teaches that “all are alike unto God,” including “black and white, bond and free, male and female” (2 Nephi 26:33). Throughout the history of the Church, people of every race and ethnicity in many countries have been baptized and have lived as faithful members of the Church. During Joseph Smith’s lifetime, a few black male members of the Church were ordained to the priesthood. Early in its history, Church leaders stopped conferring the priesthood on black males of African descent. Church records offer no clear insights into the origins of this practice. Church leaders believed that a revelation from God was needed to alter this practice and prayerfully sought guidance. The revelation came to Church President Spencer W. Kimball and was affirmed to other Church leaders in the Salt Lake Temple on June 1, 1978. The revelation removed all restrictions with regard to race that once applied to the priesthood.

The Bible and the Book of Mormon teach that monogamy is God’s standard for marriage unless He declares otherwise (see 2 Samuel 12:7–8 and Jacob 2:27, 30). Following a revelation to Joseph Smith, the practice of plural marriage was instituted among Church members in the early 1840s (see section 132). From the 1860s to the 1880s, the United States government passed laws to make this religious practice illegal. These laws were eventually upheld by the U.S. Supreme Court. After receiving revelation, President Wilford Woodruff issued the following Manifesto, which was accepted by the Church as authoritative and binding on October 6, 1890. This led to the end of the practice of plural marriage in the Church.

Written in 1842 by the Prophet Joseph Smith, these 13 statements explain the basic doctrines and practices of The Church of Jesus Christ of Latter-day Saints.

The Articles of Faith and Official Declarations 1 and 2

Since Joseph Smith’s First Vision, God has continued to guide His Church by revelation. In some cases, that revelation has included changes to the policies and practices of the Church. Official Declarations 1 and 2 announced this kind of revelation—one led to the end of plural marriage, and the other made the blessings of the priesthood available to people of all races. Changes like these are part of what it means to have a “true and living church” (Doctrine and Covenants 1:30), with a true and living prophet, led by a true and living God.

But eternal truth doesn’t change, though our understanding of it does. And sometimes revelation casts additional light on truth. The Articles of Faith serve this clarifying purpose. The Church is solidly founded on eternal truth yet can grow and change “according as the Lord will, suiting his mercies according to the conditions of the children of men” (Doctrine and Covenants 46:15). In other words, “We believe all that God has revealed, all that He does now reveal, and we believe that He will yet reveal many great and important things pertaining to the Kingdom of God” (Articles of Faith 1:9).

A vision given to President Joseph F. Smith in Salt Lake City, Utah, on October 3, 1918. In his opening address at the 89th Semiannual General Conference of the Church, on October 4, 1918, President Smith declared that he had received several divine communications during the previous months. One of these, concerning the Savior’s visit to the spirits of the dead while His body was in the tomb, President Smith had received the previous day. It was written immediately following the close of the conference. On October 31, 1918, it was submitted to the counselors in the First Presidency, the Council of the Twelve, and the Patriarch, and it was unanimously accepted by them.

Doctrine and Covenants 137–138

The revelations recorded in Doctrine and Covenants 137 and 138 are separated by more than 80 years and 1,500 miles (2,400 km). Section 137 was received by the Prophet Joseph Smith in 1836 in the Kirtland Temple, and section 138 was received by Joseph F. Smith, sixth President of the Church, in 1918 in Salt Lake City. But doctrinally, these two visions belong side by side. They both answer questions that many people—including God’s prophets—have about life after death. Joseph Smith wondered about the fate of his brother Alvin, who had died without being baptized. Joseph F. Smith, who had lost both of his parents and 13 children to untimely deaths, thought often about the spirit world and wondered about the preaching of the gospel there.

Section 137 casts some initial light on the destiny of God’s children in the next life, and section 138 opens the curtains even wider. Together, both revelations testify of “the great and wonderful love made manifest by the Father and the Son” (Doctrine and Covenants 138:3).

Announcement of the martyrdom of Joseph Smith the Prophet and his brother, Hyrum Smith the Patriarch, at Carthage, Illinois, June 27, 1844. This document was included at the end of the 1844 edition of the Doctrine and Covenants, which was nearly ready for publication when Joseph and Hyrum Smith were murdered.

Doctrine and Covenants 135–136

The afternoon of June 27, 1844, found Joseph and Hyrum Smith in jail once again, accompanied by John Taylor and Willard Richards. They believed they were innocent of any crime, but they submitted to arrest, hoping to keep the Saints in Nauvoo safe. This wasn’t the first time that enemies of the Church had put the Prophet Joseph in prison, but this time he seemed to know that he would not return alive. He and his friends tried to comfort each other by reading from the Book of Mormon and singing hymns. Then gunshots were heard, and within a few minutes the mortal lives of Joseph Smith and his brother Hyrum had come to an end.

And yet it was not the end of the divine cause they had embraced. And it was not the end of the Restoration of the gospel of Jesus Christ. There was more work to do and more revelation that would guide the Church forward. The end of the Prophet’s life was not the end of the work of God.
