When Joseph Smith was 17 year old, he was visited by the angel Moroni. Moroni told Joseph Smith about an ancient record written on gold plates. The record contained the fullness of the gospel as delivered by the Savior to ancient inhabitants of the Americas. He also told Joseph that there were tools buried with the plates that were prepared to help him translate. Moroni also quoted scriptures and taught Joseph many things before he left. One of the scriptures Moroni quoted was from the book of Malachi, although Moroni quoted it slightly differently than it reads in our Bibles. The scripture said that Elijah the prophet would be sent to restore the priesthood and “plant in the hearts of the children the promises made to the fathers, and the hearts of the children shall turn to their fathers (Doctrine & Covenants 2:2).” The priesthood keys Elijah would restore are the sealing keys that allow us to be sealed with our families.
