St. John of Damascus, An Exposition of the Orthodox Faith, Book 1, Chapter 8 has:
All then that the Son and the Spirit have is from the Father, even their very being: and unless the Father is, neither the Son nor the Spirit is. And unless the Father possesses a certain attribute, neither the Son nor the Spirit possesses it: and through the Father, that is, because of the Father’s existence , the Son and the Spirit exist, and through the Father, that is, because of the Father having the qualities, the Son and the Spirit have all their qualities, those of being unbegotten, and of birth and of procession being excepted. For in these hypostatic or personal properties alone do the three holy subsistences differ from each other, being indivisibly divided not by essence but by the distinguishing mark of their proper and peculiar subsistence.
Further we say that each of the three has a perfect subsistence, that we may understand not one compound perfect nature made up of three imperfect elements, but one simple essence, surpassing and preceding perfection, existing in three perfect subsistences.
Let’s read it again:
. And unless the Father possesses a certain attribute, neither the Son nor the Spirit possesses it
What is this attribute? Is a good attribute or bad attribute?
If it is a good attribute, then the Son and the Holy Spirit are not God, because there is a goodness that they do not have.
If it is a bad attribute, Then The Father is not God, Because there is no vice in the God.
and through the Father, that is, because of the Father’s existence , the Son and the Spirit exist
Yes, And while “the Son and the Spirit exist, because of the Father’s existence.” The Son and the Spirit can’t be God, because God is self-exist, and no one gives him anything (Romans 11:35)
and through the Father, that is, because of the Father having the qualities, the Son and the Spirit have all their qualities
So The Father gave them all their qualities. And I just notify that Saint Paul says: “Who has ever given to God, that God should repay them?” (Romans 11:35)
For in these hypostatic or personal properties alone do the three holy subsistences differ from each other, being indivisibly divided not by essence but by the distinguishing mark of their proper and peculiar subsistence.
My problem is not about being peculiar, but about possibility.
