Gordon B. Hinckley, 15th President of the Church, 1995–present
The Doctrine and Covenants is unique among our books of scripture. It is the constitution of the Church. While the Doctrine and covenants includes writings and statements of various origins, it is primarily a book of revelation given through the Prophet of this dispensation. . . . The Doctrine and Covenants is a conduit for the expressions of the Lord to His people. . . . It is evident from reading the Doctrine and Covenants that Joseph Smith had an all-encompassing understanding of the eternal purposes of God.
Franklin D. Richards, Apostle, 1849–1899
We do not conceive it possible for any unprejudiced person to arise from a careful perusal of this work [the Pearl of Great Price], without being deeply impressed with a sense of the Divine calling, and holy ordination, of the man [Joseph Smith] by whom these revelations, translations and narrations have been communicated to us. As impervious as the minds of men may be at present to these convictions, the day is not far distant when sinners, as well as Saints, will know that Joseph Smith was one of the greatest men that ever lived upon the earth and that under God he was the Prophet and founder of the dispensation of the fullness of times, in which will be gathered together into one all things which are in Christ, both which are in heaven and which are on earth.
