here. - I see you do acknowledge subordination of the Son,...good, since such is a logical observation of relational order and process, to say nothing of hierarchy. Both Unitarian and Trinitarians accept this obvious 'relation',...the latter however can fluctuate between both 'divine' and 'human' aspects of Jesus, so they can always claim Jesus humanity is being referred to in certain situational-contexts, whereas he still always has his pure or total divinity somehow ever intact within his personhood (the divine and human elements being 'fused' yet distinct), while Unitarians either maintain a purely human origin and constitution of Jesus at his conception and then only some divine infusion, anointing or joining to 'God' from his incarnational birth onwards,
but the man Jesus certainly never becomes 'God' Almighty.
I think we already addressed Heb. 1:8 here or in other threads on this subject, but I'll be working on a commentary on that verse forthcoming soon. Thorough research shows that this passage does Not necessarily prove Jesus is God, since the grammatical structure of the passage is ambiguous and can be variously translated, not to mention that the original psalm 45 that is quoted, which is about a Davidic King and his wedding to a foreign Princess, which is probably Solomon, is not being referred to as 'God' Almighty, yet the Messiah and other mighty men (judges, kings, anointed ones) can be called 'elohim', and since they are representations of 'God', this is appropriate indicating their are agents of God, and so serve in God's stead. But this exclamation can be relating a different emphasis altogether as the verse traditionally rendered "thy throne O God, is forever and ever", can also be translated(arranged) as "God is thy throne", or "your throne is God", meaning the Anointed one's power or authority is 'God', so the Messiah's throne is 'God', 'God' is his power, his authority, so he sits on God's throne,
figuratively speaking. No Jewish scripture ever teaches that the Messiah is YHWH himself, but is an anointed Man whom God chooses and makes into his Messiah(Son), who represents him, and therefore when this Messiah-King is ruling, He most certainly rules by God's power, the Messiah is 'enthroned' in God's mantle, his authority,...the throne of the Messiah is the throne of God! The Messiah-King in his divinely ordained office, has 'God' as his throne, - he sits on God's throne delegating and governing the affairs of God's kingdom.
Anyways,...its important to understanding the rightful traditional and scriptural Jewish understanding and definition of 'Messiah' here, as
YHWH's representative. While views on Messiah from within a full judeo-Christian spectrum varies from pure human to an eternal 'God-being' coming down in the flesh (with all kinds of variations inbetween, depending on your 'Christology'), I hold a
holistic view of Jesus in all his human and divine features, which includes all appropriate attributes of any human and divine qualities, both inherent and/or acquired (additionally granted or brought into being by joining, merging or transformation).
My Christology is not limited to any literal definition, but must include all that is figurative, allegorical and esoteric, since we do not only observe the outer dress of the logos, but its inner meangings and values.
