According to Daniel Ludlow, Moroni's book which bears his own name was evidently written sometime between A.D. 400 and 421. Thus it was written at least 15 years after the beginning of the battle of Cumorah. Yet Moroni indicates that some Nephites are still alive, for he says the Lamanites are putting to death every Nephite "that will not deny the Christ" (Moroni 1:2). [Daniel H. Ludlow, A Companion to Your Study of the Book of Mormon, p. 195] [See the commentary on Mormon 8:3,5]
