**To say that the Father is greater than the Son does not mean that the only begotten Son does not possess the full nature of the Father.**
The Son DOES possess the full nature of the Father.........that’s why Paul said in Col. 2:9, “For IN him DWELLETH ALL the fulness of the Godhead bodily”.
Which is not unlike:
“Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that DWELLETH IN ME, he doeth the works.” John 14:10
**..that the Son is God.**
He isn’t if you take the omniscient, omnipotent, and omnipresent Father out of him. Of course, that’s not going to happen.
