So Mary is then the mother of 1\3 of the Godhead meaning she is the earthly mother of Christ Jesus the risen King..

Meaning she is the mother of His humanity because HE was before he became Flesh..

For she bore the earthly body of Christ.. His Spiriutal body was before He became flesh. This is why His kingdom is not of this world and why we are not to know men according to the flesh.. For Christ true reign and rule is a Spiritual Kingdom.. Not built with the hands of men. Hebrews is also an awesome read..We see many times in the OT where He was called the Angel of the Lord..

He is called Emmanuel on earth meaning Christ is with us.. Now He is the risen King and seated on the right hand side of God. the Mediator between God and men..
Do you not understand, dear one, that God is not divided? A fraction, consisting of a numerator and a denominator, is in point of fact, a mathematical operation of DIVISION (1 divided by 3, in your example).
There can be no "1/3 of the Godhead." "If you have seen me, you have seen the Father." Their persons are distinct, yet undivided, just as Christ's natures were distinct, yet undivided.
Think of it this way: When you are quiet, sometimes you hear your own inner voice. So one is thinking, and one listening- yet are these divided? Is thinking 1/2 of your person? There can be no such ratio, for you think from who you are, and are as you think.
Regarding mothers, bodies, and spirits:
Do you indeed have a spirit? And is that spirit wed at this time to your fleshly body?
Do you only resemble your mother physically, or in your personality? Even human spirit was NEVER intended to be torn from its flesh, this is a consequence of the Fall.
Our mothers carry us- body and spirit- and bear us forth, flesh and spirit. No human or divine spirit can be born in flesh without the mother being its mother indeed.
You say His kingdom is not of this world, quoting Jesus' answer o Pilate and to the Pharisees. But His kingdom is in this world "for now have the kingdoms of this world become the Kingdom of our God." When He said that His kingdom was not of this world, what He was saying is that His Kingdom is not WORLDLY. He did not say that said Kingdom was not in this world, in fact, He taught us to pray that His Kingdom would come. "The earth is the Lord's and the fulness thereof."
Your perspective here has indicated a certain other error on your part, that of Gnosticism and its false condemnation of things material.
One last thing: He is not seated at the right hand side of God, as a sort of Divinen wingman, two pals side by side. Rather, He is seated at the right hand of the Father, meaning He is the power and oath of the Father.
Best regards
