The Bible does indeed call Jesus "theos" but this is not a word that is as limited in Greek or Hebrew as it is in English.
In going back to the Hebrew words that are translated “God” we see "ʼEl", probably meaning “Mighty One; Strong One.” (Gen 14:18)
It is used with reference to Yahweh, to other gods, and to men. It is also used extensively in the makeup of proper names, such as Elisha (meaning “God Is Salvation”) and Michael (“Who Is Like God?”). In some places ʼEl appears with the definite article (ha·ʼElʹ, literally, “the God” as in Greek with "ho theos") with reference to Jehovah, thereby distinguishing him from other gods. (Gen 46:3; 2Sam 22:31)
At Isaiah 9:6 Jesus Christ is prophetically called ʼEl Gib·bohrʹ, “Mighty God”, not ʼEl Shad·daiʹ [God Almighty], which is applied to Jehovah at Genesis 17:1.
The Hebrew word ʼelo·himʹ (gods) appears to be from a root meaning “be strong.” ʼElo·himʹ is the plural of ʼelohʹah (god). Sometimes this plural refers to a number of gods (Gen 31:30, 32; 35:2), but more often it is used as a plural of majesty, dignity, or excellence. ʼElo·himʹ is used in the Scriptures with reference to Jehovah himself, to angels, to idol gods (singular and plural), and to men.
So "theos" (Greek) and "elohim" (Hebrew) both mean either "God" or "a god"....a divine being or one who has divine authority. No one can deny that Jesus is a divine being, one coming directly from his God and Father, who was given divine authority. (Matt 28:18)
There are two individuals who are spoken about in Gen 1:26. The Creator, YHWH and his firstborn son. The son was used by the Father as the agency through whom creation came, as Paul stated in Col 1:15,16...
"He is the image of the invisible God, the firstborn of all creation. 16 For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things have been created through Him and for Him." (NASB)
Please read the words carefully. An image of something is not the original...it is a reflection of the original.
The term "firstborn" means that he is the first of God's sons (of which he has many.) "Only begotten" means that he is an "only child" of his kind, but still "begotten", which means he needed a "begetter"...a Father who existed before him.
There is no one like this uniquely created son because he is the first and only direct creation of his Father. This son was then used by the Father to fabricate the raw materials that God had brought into existence. There is only one Creator and there is one who was at his Father's side through the whole process as a "master craftsman". (Prov 8:22, 30, 31)
It may well have been the Logos (which means spokesman) because he spoke on behalf of his God. If "no man may see God and yet live", then this was not God....it was his representative, delivering an important message about the birth of Isaac. The angels that accompanied him went on to rescue Lot and his family from Sodom before they brought the cities to ruin. These angels too ate and drank when in human form.
Of course, no one can dispute that Jesus was made "a little lower than the angels" as a human on earth.....he said he was from "the realms above" and that he was sent by God to offer a ransom for Adam's children as a means to reconcile them with their Creator.
However, the scriptures do not identify Jesus as Yahweh......not once. Jesus called his Father "the only true God" without including himself. (John 17:3) The apostles identified the Father as their "one God" separately to Jesus their Lord. (1 Cor 8:5, 6)...were they mistaken? Do you just ignore those scriptures that expose your trinity as false?
