One of the first sources I ever read for information on Mormonism came from an entry in a book entitled Concise Dictionary of Cults and Religions by William Watson (Chicago, Il.: Moody Press, 1991). It was during my sophomore year of high school (1997-1998) that I borrowed the book from my aunt. I now know that the excerpt was shoddy and presented a very skewed view of Mormonism, but one line in particular still haunts me (emphasis mine):
Mormonism’s view of the Trinity is not the same as that of orthodox Christianity. God “was once as we are now and is an exalted man. The Father has a body of flesh and bone as tangible as man’s.” Every Mormon male can seek to become a god. This doctrine is clearly polytheism. Jesus is one god among many gods; the spirit brother of Lucifer; a polygamist. The Holy Spirit is personage of spirit. 
My 16-year-old self balked at that line. I found it incredible that anyone could believe in a religion where men could seek to become gods, but women could not. As it turned out, most of my LDS friends balked at that line as well. Throughout the remainder of high school and my undergraduate years at BYU, whenever the subject came up, my Mormon friends would assure me that women could become gods just as men could. I soon decided that this had been one of the many inaccuracies in the Dictionary’s entry on Mormonism and allowed the matter to slip from my mind.
Today I am not so certain that the dictionary was wrong altogether, as opposed to presenting an older strain of LDS thought that is now very rare. Consider what Bruce R. McConkie had to say about the exaltation of women in Mormon Doctrine (under the entry for “QUEENS;” emphases his):
If righteous men have power through the gospel and its crowning ordinance of celestial marriage to become kings and priests to rule in exaltation forever, it follows that the women by their side (without whom they cannot attain exaltation) will be queens and priestesses. (Rev. 1:6; 5:10.) Exaltation grows out of the eternal union of a man and his wife. Of those whose marriage endures in eternity, the Lord says, “Then shall they be gods” (D. & C. 132:20); that is, each of them, the man and the woman, will be a god. As such they will rule over their dominions forever. 
And now consider that this entry made it onto apostle Marion G. Romney’s list of objections to the book:
January 28, 1959
Dear President McKay:
This is my report on MORMON DOCTRINE, by Bruce R. McConkie, which on January 5, you asked me to read.
As to the book itself, notwithstanding its many commendable and valuable features and the author’s assumption of “sole and full responsibility” for it, its nature and scope and the authoritative tone and style in which it is written pose the question as to the propriety of the author’s attempting such a project without assignment and supervision from him whose right and responsibility it is to speak for the Church on “Mormon Doctrine.” Had the work been authoritatively supervised, some of the following matters might have been omitted and the treatment of others modified.
C. Miscellaneous Interpretations. (Exhibit IV)
Women to be gods, page 551 
One could argue that the specifics of Romney’s objection are not entirely clear from this brief description, but McConkie’s own entry was concise and left little room for interpretation. It would seem, then, that Romney’s objection had to do with McConkie’s declaration that women could become gods. The church certainly teaches that women can now, and even quotes this excerpt in its current manuals.  But it would appear that not all Mormon leaders have always believed that women could become gods—or perhaps, have not wanted members to think that it was incumbent upon them to believe such.
Whatever phases and transitions the Mormon doctrine of exaltation has gone through, it has always been a given that men can become gods. The nature of what a “god” is has been subject to interpretation and debate, but that men could become such a thing never has been. That this was ever even a question where women are concerned is significant.
 Bruce R. McConkie, Mormon Doctrine (Salt Lake City, Ut.: Bookcraft, 1998), 613. I typed this out of my personal copy of the book, which is an 18th printing of the 2nd edition. However, a friend who owns a 1st edition (1958) of the book has confirmed to me that the entry on “QUEENS” is the same. It is found on p. 551 of the 1st edition.
