This great and good man [Joseph Smith the Prophet] was led, before his death, to call the Twelve together, from time to time, and to instruct them in all things pertaining to the kingdom, ordinances, and government of God. He often observed that he was laying the foundation, but it would remain for the Twelve to complete the building. Said he, ‘I know not why; but for some reason I am constrained to hasten my preparations, and to confer upon the Twelve all the ordinances, keys, covenants, endowments, and sealing ordinances of the priesthood . . . for, said he, the Lord is about to lay the burden on your shoulders and let me rest awhile; and if they kill me . . . the kingdom of God will roll on, as I have now finished the work which was laid upon me, by committing to you all things for the building up of the kingdom according to the heavenly vision, and the pattern shown me from heaven.’ (“Proclamation,” Millennial Star, 5 [March 1845]: p. 151).
President Joseph Smith testified, "I have lived until I have seen this burden, which has rested on my shoulders, rolled on to the shoulders of other men; . . . the keys of the kingdom are planted on the earth to be taken away no more for ever. . . . No matter what becomes of me" (Deseret News, Dec. 21, 1869, p. 2).
The Church of Jesus Christ of Latter-day Saints is the only Church that:
1. Is acknowledged by Christ as His own (D&C 1:30-31; 115:4)
2. Was established by Joseph Smith himself, through revelation (D&C 115:4). The only Church the Prophet was a member of was The Church of Jesus Christ of Latter-day Saints.
3. Teaches all the doctrines Joseph Smith taught (Endowment of the Holy Priesthood, Baptism for the Dead, tithing, the Word of Wisdom, continual revelation through the President of the Church, eternal marriage, the proper mode and manner of baptism and bestowing the Gift of the Holy Ghost, temple work for the dead, the three degrees of glory, the need of the Sealing Authority, missionary work, gift of tongues, the importance of the Fall, the infinite reach of the Atonement, the age of accountability, the innocence of little children, etc.)
