We are ONE god and don't you forget it!
Jack, there's "enough" single-God verse mentions in both the Book of Mormon and Lds Doctrine & Covenants to lull Mormons into a slumber that, they, too, are single-God Christians.
The problem is that Joseph Smith evolved into "multiple-god" Mormonism in the 1840s...and in Mormonism, the latter "revelations" always trump the former ones.
Still, if you go back to Mormonism's origins, what's of interest is that between 1830 and almost mid-way through 1833, Joseph Smith largely stuck with trinitarian beliefs that he inserted into the...
...1830 Book of Mormon,
...1833 Book of Commandments
...and 1835 Doctrine & Covenants
-- although he was also a "modalist" at the time (the belief that the same divine personality reveals himself in 3 venues or "modes").
(I strongly encourage Lds "lurkers" to go back & study their own 1830-1833 "roots" as far as who God is):
Doctrine & Covenants:
As well as those who should come after, who should believe in the gifts and callings of God by the Holy Ghost, which beareth record of the Father and Son; which Father, Son, and Holy Ghost are one God. (D&C 20:27-28, 1830)
And the Father and I are one. I am in the Father and the Father in me... (D&C 50:43...1831...Smith copied this from John 10; John 17)
And that I am in the Father, and the Father in me, and the Father and I are one (D&C 93:3, 1833)
...even one in me [Jesus] as I am one in the Father, as the Father is one in me, that we may be one (D&C 35:2, 1831)
Book of Commandments, 1833 (the original D&C):
Lectures of Faith, Lecture 5, v. 2: And he [Jesus] being the only begotten of the Father, full of grace and truth, and having overcome, received a fulness of the glory of the Father--possessing the same mind with the Father, which mind is the Holy Spirit, that bears record of the Father and the Son, and these three are one, or in other words, these three constitute the great, matchless, governing and supreme power [singular] over all things: by whom all things were created and made; and these three constitute the Godhead, and are one: The Father and the Son possessing the same mind, the same wisdom, glory, power and fullness: Filling all in all--the Son being filled with the fulness of the Mind, glory and power, or, in other words, the Spirit, glory and power of the Father--posessing all knowledge and glory, and the same kingdom: sitting at the right hand of power, in the express image and likeness of the Father--a Mediator for man--being filled with the fulness of the Mind of the Father, or, in other words, the Spirit of the Father... [Note: This was removed from the 1835 D&C...Why?]
Book of Mormon:
Intro: Testimony of Three Witnesses: And the honor be to the Father, and to the Son, and to the Holy Ghost, which IS [not ARE] one God.
And now, behold, this is the doctrine of Christ, and the only and true doctrine of the Father, and of the Son, and of the Holy Ghost, which IS [not ARE] one God. (2 Nephi 31:21)
...the Father, and the Son, and the Holy Ghost are one; and I am in the Father, and the Father in me, and the Father and I are one...the Father, and I, and the Holy Ghost are one. (3 Nephi 11:27,36)
...every thing shall be restored to its perfect frame, as it is now, or in the body, and shall be brought and be arraigned before the bar of Christ the Son, and God the Father, and the Holy Spirit, which IS [not ARE] one eternal God... (Alma 11:44)
...given unto him to dwell in the presence of God in his kingdom, to sing ceaseless praises with the choirs above, unto the Father, and unto the Son, and unto the Holy Ghost, which are one God, in a state of happiness which hath no end. (Mormon 7:7: Please note: the original 1830 Book of Mormon had the word "is" prior to one God...BoM editors then changed it to "are"...a "shaking-the-head" kind of thought given that they left other "testimony" untouched -- such as the 3 witnesses -- along with 2 Nephi 31:21 and Alma 11:44)
...there is a true and living God...Is there more than one God? And he answered, No (Alma 11:27-29)
...Jesus showed himself unto this man in the spirit...and all this, that this man might know that he was God... (Ether 3:17-18)
We are ONE god and don't you forget it!
