From the Introduction printed in the Doctrine & Covenants:
“The Doctrine and Covenants is a collection of divine revelations and inspired declarations . . .
“. . . 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. .
“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.”
