From the Coptic Psalmody on terms of theosis and partaking of the divine nature:
God is Emmanuel
The True Food
The Immortal Tree
Of Life
Here we start with the idea that the Tree of Life is God, who is our sustenance. Only God is immortal, and by partaking of immortality, it is an uncreated energy of God.
Come to us today
O Christ our Master
Shine upon us
With Your exalted divinity
Send to us
This great grace
of Your Holy Spirit
the Comforter
Here, we ask God to give us the light of His divinity, and we call this "This great grace of Your Holy Spirit." Therefore, grace is the uncreated energy of God, and His light is an uncreated energy, which comes from from His divinity.
You are the bush
which Moses saw
Flaming with fire
And was not consumed.
That is the Son of God
Who dwelt in your womb
The fire of the Divinity
Did not consume your body.
This idea about the "fire of His divinity" was repeated in most other Theotokias of the week. Here, we see the Divinity burns, as is popular among some contemporary EO's in their eschatology. Nevertheless, we understand that this burning is not a burning of destruction, but of glorification. This fire does not consume, but deifies. Therefore, we hail the Theotokos:
Hail to the incorrupt vessel
Of the divinity
Which heals everyone
Who drinks from it
Notice the fire of the Divinity IS the Divinity. Her womb held the fire of divinity, and now she is called the "vessel of the divinity." The fire being divinity is uncreated. This distinction is implied and necessary. It agrees with Palamism. While the hymns are quite strong in their language, nevertheless, the Church teaches we are not partaking of the essence of the divinity. It is implied in this, whatever we partake of from the divine nature is necessarily distinct into whatever one wants to call it, grace, energy, glory, love, power, all from God, and all uncreated.
