Following this section is the Words of Mormon. This small book, said to be written in AD 385 by Mormon, is a short introduction to the books of Mosiah, Alma, Helaman, Third Nephi, and Fourth Nephi. These books are described as being abridged from a large quantity of existing records called "the large plates of Nephi" that detailed the people's history from the time of Omni to Mormon's own life. The Book of Third Nephi is of particular importance within the Book of Mormon because it contains an account of a visit by Jesus from heaven to the Americas sometime after his resurrection and ascension. The text says that during this American visit, he repeated much of the same doctrine and instruction given in the Gospels of the Bible and he established an enlightened, peaceful society which endured for several generations, but which eventually broke into warring factions again.
