"Do you believe in one Lord Jesus Christ, the only begotten Son of God, begotten of the Father before all ages, Light of Light, true God of True God, begotten not made of one essence with the Father, by Whom all things were made.....?"
Do you hold this belief?
Ok... I will say that I suspect that it is true - However, I cannot affirm it wholly, because I have no right or warrant to define God beyond what has been given. How can one declare a formula for what is not defined? In that, assuming 'essence' is presumptuous. Yeshua is YHWH (by empirical proof). But how that works, I cannot say... and neither can you.
I don't say this to be contentious - But such a precise definition cannot be proven.
