christians believe in 3 presence that is father, holy spirit , jesus ('word' after getting flesh). all three had the status of God, thus being equal.
however if we research roman christian scriptures. we can see that 'word' need to be supported by father (just like how Jacob was supported on right hand of God).
and when 'word' need to be on earth in the form of man. 'word' need the aid of holy spirit to be born in womb of woman. word does not posses the ability to perform miracle by itself or mightiness as it seems. but still based on what was mentioned in their doctrine, status of 'word' is equal to the other two.
father does not need holy spirit to be inside father's body. while 'word' need to have holy spirit supporting each other. and if we look at holy spirit ranking by comparing to father, holy spirit does not stay in the same realm that is in the realm of father's throne. but holy spirit stays in the realm of water. thus we see holy spirit hovers over the water. realm of water is the realm below father's throne.
