Lineage continues to be important throughout the Book of Mormon, as evidenced by Mormon's own declaration of Lehite descent (3 Nephi 5:20). Understanding the Book of Mormon as a lineage history has important implications. As Sorenson noted, “The ‘history’ kept by a lineage is not, of course, a comprehensive account of everything taking place in the area.” Its concern is more limited to the things deemed important to that lineage group and impacting them most.
