You replied : It can lead to paganism because we begin to associate/confuse His nature with ours. Thus, we begin to think of an "angry" God, a "vengeful" God, a passionate God, just the way we are
I agree that an incorrect notion of God can lead to problems. But I think starting from God's Person or God's nature doesn't necessarily lead to an incorrect notion. Of course, when man sees God as a "bigger" man, it becomes more likely that we forget the Transcendant nature of Him who IS.
We know of God through His Hypostatic revelations. One, the Word, became Incarnate, so that we may establish a loving and personal relationship with God, and never confuse our nature with His.
God acts through His nature. His Personhood is distinct only in relationship to the other Persons of the Trinity. Again, the West/East approach!

God is distinct in three Hypostases only to us. God is not divisible by nature, jo. We can know God only by His revelations — through the Hyposatic economy.
