Totally circular, since its been clearly articulated how the BELIEF was 'doctrinally developed', and conceptually accepted thru a process of logics and rationale within certain theological or more pointedly 'Christological' contexts. - My former post and most others on this particular still HOLDS, as well as Bart Ehrmans presentation in his scholarly work on the matter.
Now as to whether one BELIEVES Jesus is God or not (in reality, as it that could really be verified or proven by any certain criteria) is another matter, or more specifically a matter of personal 'belief' and one's chosen 'preference' of Christology. - and that my dear is the truth of this relative matter.
Absolute REALITY if we would consider it, is that ALONE which is ABSOLUTE, and by classical or traditional theist theology and even in universal metaphysical definitions, can only be 'God' or 'Deity' itself (pure Spirit-Energy-Consciousness), if we are to consider the pure essence and IDentity of 'God' himself (in its essential formless incorporeal being) - This 'Deity' is the one and only absolute divine, indivisible, universal, eternal, infinite, timeless, spaceless reality. - all else (creation in space-time) is but a form, expression, manifestation, extension or emenation of 'God' ....so in that case Jesus would naturally be a 'Son' of said 'God', in a similar but nuanced way that all souls, to one degree or another, in one form or fashion...are the 'offspring' of 'God'.
Give Jesus all the Godhood you wish, but the relational differences and distinctions STILL EXIST in the realm of personality-relationships, as these are still 2 personalities RELATING to each other, per the creed's definition. Again, DEEM these 2 or 3 personalities within a 'Trinity' as being of 'one same essence' then its just the same truth of 'monotheism' and even 'monism' but with a little added 'metaphysical gymnastics' thrown in....JUST to make 'Jesus' into 'Almighty God', which in the greater cosmic context of understanding reality in all its dimensions is really NOT necessary to believe as a 'dogma' or a 'truth', but just one way of looking at and relating to 'God' and his Creative Agency, whether these 'sons' be more or less divine or human (assuming they incarnate on various worlds from time to time on 'bestowal missions' to reveal 'God' to the inhabitants of those worlds). - Then add the good ole Holy Spirit into the equation, as if to 'personify' the Spirit of God, when this is again unnecessary, since we relate to the One Spirit of 'God' just the same, whether 'personally' or 'otherwise'.
Add onto to this that 'God' is naturally the Father of spirits,...there are many spirit-offsprings of 'God'.
We could go on........
Let's not go on. I believe that Jesus is God, you don't. Let's leave it at that.
