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.
John 14:26
King James Version (KJV)
26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.
Did that happen? I believe it did - - 50 some days after He spoke this. Therefore, it seems that, if what you believe is only what you can figure out, then you withhold from yourself something helpful that was provided.
If the "all things" that they were to be taught were possible to be recorded, ink on paper, why then did they not get busy right away with a writing project?
Just a side note: The dramatic conversion of the Apostles at Pentecost is a strong "proof" (strong and powerful indicator?) of the truth of Christianity.
