Since i wrote that years ago, and am far more articulate now a days; please ask, and will explain anything that is needed.
You could do with studying what scholars put forward, and not what Jewish Tradition dictates:
Elyon - Wikipedia
Deuteronomy 32:7-9 Remember the days of old. Consider the years of many generations. Ask your father, and he will show you; your elders, and they will tell you. When the Most High gave to the nations their inheritance, when he separated the children of men, he set the bounds of the peoples according to the number of the
children of 'God'. For Yahweh's portion is his people. Jacob is the lot of his inheritance.
Christians do not put forward the argument, there was a Divine Council of Elohim and One God Most High (El Elyon),
scholars do; as the text shows two references in multiple places (2 Samuel 22:14 & Psalms 18:13, Psalms 50:14, Psalms 78:35, Psalms 92:1), as the Jews after the Babylonian Exile have been trying to follow a stricter form of monotheism, that didn't exist in the Tanakh.

The ideas of an incarnation of YHVH Elohim 'becoming' 'Yeshua' Elohim (Psalms 98:3, Isaiah 52:10) is also throughout the Tanakh (H3444 + H1961 = Exodus 15:2-3, Psalms 118:14-21, Isaiah 12:2), and Jewish reading comprehension is to blame.
In my opinion.
