Recognizing that the Universal Father has created(begotten) divine sons whom he calls 'gods' and furthermore qualify as 'elohim' (which includes human leaders, ruler, judges, administrators, etc.) does not make the recognizer a 'polytheist', for there is always and absolutely only ONE UNIVERSAL FATHER, whose primacy is foremost and utmost, because The Father is the Most High God, the Father of all in the cosmos. Only One eternal, infinite, universal, omnipresent, ultimate, primal DEITY...qualifies as 'Deity' proper, the First Source and Center of all things and beings, the unbegotten itself.
Recognizing this is wholly monotheistic, since there is only one divine Creative Nature, Essence, Being, even though there may be many gods, sons and co-creators within a universal hierarchy who are also 'elohim'.
There is always and forever one infinite and universal Father.
No problems.
God is ONE, always, forever. God extends himself and brings forth (begets) offspring. All is an extension of 'God'. There is only 'God', and the expression(s) of 'God'. One God Being.
