G. T. Harrison argues that the concepts of "faculties" and "immortal souls," and iron-working in the New World, are all anachronisms in the Book of Mormon.

(4) FACULTIES This word is not found in the Bible, and the ancients knew nothing of the division of the mind into “faculties” (Jacob 3:11; Mosiah 29:14). The word if much too modern to be found in a true, accurate, historical record of alleged Book of Mormon times.
(5) IMMORTAL SOUL This expression is not found in any ancient language, and is not found in the Bible. Immortal of course, means not subject to death, which is contrary to the teachings of the Bible. (Eccl. 9:5; Mosiah 2:38)
(6) IRON There is no record that the Jews had knowledge of producing iron and its plentiful use as early as 600 B.C., when the Nephites allegedly left Jerusalem. There is nothing on which the modern archaeologists or our American antiguities are more unanimously agreed upon than the matter of the absence of the knowledge of iron, and therefore its non-use among the natives of America.” (2 Nephi 5:15; Jarom 1:8)
