ELOHIYM: All references to “God” in Genesis chapter one, are the Hebrew word, “Elohiym” (Strong’s Hebrew reference #430).
The word refers to more than two (Martin/Ankerberg 1985). There is a word in Hebrew that refers to more than one but not more than two, but Elohiym is not that word.
The word “Elohiym, is a reference to the Triune Godhead.
Genesis 1:1 specifically tells us that it is the Triune God--the Godhead (Elohiym)---who created all things (Isaiah 44:24, 45:18, John 1:3,10). This is the first Biblical evidence that Jesus is Jehovah, not simply a subordinate that God “used” to create all things. According to Philippians 2:10-11, which is a New Testament quote of Jehovah who is speaking in Isaiah 45:23, Jesus is the LORD GOD—Yahweh Elohiym—of Genesis1-3.
The fullness (entirety) of the Godhead resides in Jesus in physical form (Colossians 2:9). We serve a Triune God who is one. The Old Testament reference to the "Holy of Holies" (where the Ark of God resided) literally means the Holy place of the Holy Ones—i.e., the Godhead (Cooke).
Do we understand how God can be three yet be one? No, we do not. It is as impossible for man to analyze and pry apart the Godhead as it would be to attempt to separate the soul and spirit; only God has sufficient understanding and power to accomplish such a thing in His triune personage and yet remain one.
It is sin to theologically transform the Triune Godhead into a hierarchal, idolatrous, triad. Just so, it is sin to theologically change the holy, one flesh, relationship of marriage of a woman and a man into a hierarchal duo with a god-man at the helm.
Spiritual hierarchies created by man, accomplish nothing less than the conversion of our triune God into a pagan triad of three gods, convert husbands who insist they must play the "Christ role" in marriage into mediatorial gods, and women who accept them as such into idolators.
