Jesus explained to Philip that in fact he could only see the Father Almighty where He intersected Philip's sensing ability, as Jesus, God with us, for He, The Father was in Jesus and Jesus was/is in The Father.
The poster to whom I was trying to relate the limits to wanted a different answer, one which would put the God that poster prefers to question into a rut of necessity to come from some greater source. Perhaps you noticed that the poster began the derisions when the answer was not following the poster's set up.
The essence of what I was seeking to convey was that God is so much more than our dimensional limits can sense or even imagine, that we can no more answer why God expresses in three persons than we can see the being to whom the hand was attached, seen in Daniel Chapter Five.
God, in Whom is no shadow of turning, does not come 'from', He is. His name is I AM. As Jesus He passed through our set of dimensional limits, but no one saw The Father Almighty, only where He passed through our limits.
Rome says:
We've shown you the Mother; why won't that suffice?
