The Doctrine and Covenants is a collection of divine revelations and inspired declarations given for the establishment and regulation of the kingdom of God on the earth in the last days. Although most of the sections are directed to members of The Church of Jesus Christ of Latter-day Saints, the messages, warnings, and exhortations are for the benefit of all mankind, and contain an invitation to all people everywhere to hear the voice of the Lord Jesus Christ, speaking to them for their temporal well-being and their everlasting salvation.

Most of the revelations in this compilation were received through Joseph Smith, Jun., the first prophet and president of The Church of Jesus Christ of Latter-day Saints. Others were issued through some of his successors in the Presidency. (See headings to Sections 135, 136, and 138, and Official Declarations 1 and 2.)

The book of Doctrine and Covenants is one of the standard works of the Church in company with the Holy Bible, the Book of Mormon, and the Pearl of Great Price. However, the Doctrine and Covenants is unique because it is not a translation of an ancient document, but is of modern origin and was given of God through his chosen prophets for the restoration of his holy work and the establishment of the kingdom of God on the earth in these days. In the revelations one hears the tender but firm voice of the Lord Jesus Christ, speaking anew in the dispensation of the fulness of times; and the work that is initiated herein is preparatory to his second coming, in fulfillment of and in concert with the words of all the holy prophets since the world began.

Joseph Smith, Jun., was born December 23, 1805, in Sharon, Windsor County, Vermont. During his early life he moved with his family to Manchester, in western New York. It was while he was living near Manchester in the spring of 1820, when he was fourteen years of age, that he experienced his first vision, in which he was visited in person by God, the Eternal Father, and his Son Jesus Christ. He was told in this vision that the true Church of Jesus Christ that had been established in New Testament times, and which had administered the fulness of the gospel, was no longer on the earth. Other divine manifestations followed in which he was taught by many angels; it was shown to him that God had a special work for him to do on the earth, and that through him the Church of Jesus Christ would be restored to the earth.

In the course of time Joseph Smith was enabled by divine assistance to translate and publish the Book of Mormon. In the meantime he and Oliver Cowdery were ordained to the Aaronic Priesthood by John the Baptist in May 1829 (D&C 13), and soon thereafter they were also ordained to the Melchizedek Priesthood by the ancient apostles Peter, James, and John (D&C 27: 12). Other ordinations followed in which priesthood keys were conferred upon them by Moses, Elijah, Elias, and many ancient prophets (D&C 110; 128: 18, 21). These ordinations were, in fact, a restoration of divine authority to man on the earth. On April 6, 1830, under heavenly direction, the Prophet Joseph Smith organized the Church, and thus the true Church of Jesus Christ is once again operative as an institution among men, with authority to teach the gospel and administer the ordinances of salvation. (See Pearl of Great Price, Joseph Smith-History 1: 1-75; D&C 20.)

These sacred revelations were received in answer to prayer, in times of need, and came out of real-life situations involving real people. The Prophet and his associates sought for divine guidance, and these revelations certify that they received it. In the revelations one sees the restoration and unfolding of the gospel of Jesus Christ and the ushering in of the dispensation of the fulness of times. The westward movement of the Church from New York and Pennsylvania, to Ohio, to Missouri, to Illinois, and finally to the Great Basin of western America, and the mighty struggles of the saints in attempting to build Zion on the earth in modern times, are also shown forth in these revelations.

Several of the earlier sections involve matters regarding the translation and publication of the Book of Mormon (see Sections 3, 5, 10, 17, 19). Some later sections reflect the work of the Prophet Joseph Smith in making an inspired translation of the Bible, during which many of the great doctrinal sections were received (see, for example, Sections 37, 45, 73, 76, 77, 86, 91, and 132, each of which has some direct relationship to the Bible translation).

In the revelations the doctrines of the gospel are set forth with explanations about such fundamental matters as the nature of the Godhead, the origin of man, the reality of Satan, the purpose of mortality, the necessity for obedience, the need for repentance, the workings of the Holy Spirit, the ordinances and performances that pertain to salvation, the destiny of the earth, the future conditions of man after the resurrection and the judgment, the eternity of the marriage relationship, and the eternal nature of the family. Likewise the gradual unfolding of the administrative structure of the Church is shown with the calling of bishops, the First Presidency, the Council of Twelve, and the Seventy, and the establishment of other presiding offices and quorums. Finally, the testimony that is given of Jesus Christ-his divinity, his majesty, his perfection, his love, and his redeeming power-makes this book of great value to the human family and of more worth than the riches of the whole earth.

A number of the revelations were published in Zion (Independence), Missouri, in 1833, under the title A Book of Commandments for the Government of the Church of Christ. Concerning this publication the elders of the Church gave solemn testimony that the Lord had borne record to their souls that these revelations were true. As the Lord continued to communicate with his servants, an enlarged compilation was published two years later in Kirtland, Ohio, with the title Doctrine and Covenants of the Church of the Latter Day Saints. To this publication in 1835, the written testimony of the Twelve Apostles was attached as follows:

The Testimony of the Witnesses to the Book of the Lord's Commandments, which commandments He gave to His Church through Joseph Smith, Jun., who was appointed by the voice of the Church for this purpose:

We, therefore, feel willing to bear testimony to all the world of mankind, to every creature upon the face of the earth, that the Lord has borne record to our souls, through the Holy Ghost shed forth upon us, that these commandments were given by inspiration of God, and are profitable for all men and are verily true.

We give this testimony unto the world, the Lord being our helper; and it is through the grace of God the Father, and His Son, Jesus Christ, that we are permitted to have this privilege of bearing this testimony unto the world, in the which we rejoice exceedingly, praying the Lord always that the children of men may be profited thereby.
