“The Eternal Destruction of Both Soul and Body”

"This expression does not have reference to the annihilation of the body and spirit of the wicked. Such an interpretation would contradict many passages of scripture, the better part of which have been spoken by Nephite prophets. The Book of Mormon is most emphatic that the resurrection is universal and that it consists of the inseparable union of body and spirit. (See Alma 11:44-45; Alma 40:19-23.) The body and soul could properly be thought of as having been destroyed in the sense that they come forth in some resurrection other than the first or celestial resurrection. Such was Lehi's meaning in this instance (see 1 Nephi 14:3)." (McConkie and Millet, Doctrinal Commentary on the Book of Mormon, vol. 1, p. 189)
