The 'everything is god' is the metaphysical problem intrinsic to the Trinity due to its expressed teachings of-
Hypostatic union
Indivisibilty
Omnipresence
Can you cite any authority? The hypostatic union concerns the christology of Christ, His nature, that he was/is God-man. It does not stand for the proposition that "everything is God" as you claim and accordingly can't be a metaphsical problem intrinsic to the Trinity. The triune God's indivisibility refers to the fact that the three persons of the Trinity - Father, Son and Holy Spirit, are inseparable, indivisible among themselves, yet distinct. It does not mean "Everything is God." I think you are comingling Hindu religions with Trinitarian Christianity.
In most formularies the doctrine is stated by saying that God is one in His essential being, but that in this being there are three Persons, yet so as not to form separate and distinct individuals. They are three modes or forms in which the divine essence exists. ‘Person’ is, however, an imperfect expression of the truth in as much as the term denotes to us a separate rational and moral individual. But in the being of God there are not three individuals, but only three personal self-distinctions within the one divine essence. (New Bible Dictionary, 1299, 1300)
With respect to the Almighty's "omnipresence," what exactly are we arguing about? Are you saying that Hinduism and western theism hold to the exact same definition of omnipresence? I'm trying to sharpen the issue, and see how it relates to whether Jesus was, and is, God. Help me understand what point you are trying to make with respect to God's "omnipresence."
