[W]e should point out that
the word "monotheism" can have two different meanings in such a
discussion: a Jewish "Old Testament" meaning (one God, no
"Father-Son" distinction, no lesser gods), and a Johannine
meaning (one God, who dwells in separate other gods, and whose
presence constitutes their divinity; John 14:10; Mt. 19:17). Mormonism
agrees with this Johannine meaning (cf. 1 Nephi 13:24-5;
14:25-7), which must be assumed whenever we speak of the Mormon doctrine of
deification. Even Israelite "polytheism" believed in the existence of
a High God (Elohim), who was the "universal power behind the national
gods," the "One Power" who "includes all gods," and
the one in whom "the fulness of deity is
comprehended" (Ringgren and Anderson; see p. 37, in Ancient Texts and
Mormonism Introduction and Proem [Proem]). Thus, when we discuss the
"polytheism" of the patriarchs it is to be assumed that
a single Divine Power stands behind the lesser gods, though lesser
gods there were, as modern archeology affirms (cf. 1 Cor. 8:5 -6). Mormonism, too, believes in a single
"God of all other gods" (D&C 121:32), whose indwelling
presence makes the rest divine, i.e. the "One God" whose
"fulness" deifies "the many." This should not, however, be confused
with "henotheism," which posits "One God" who appears in
many forms, or under different names; this is the idea which occurs in
Trinitarian "modalism," or the belief that the "persons" of
the Trinity are but different "aspects" of the same being. (Eugene Seaich, Ancient Texts and Mormonism, Volume 2--The
