The way I was taught in Orthodoxy was basically using a couple of passages in John.
First passage: John 1:1-5
1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was with God in the beginning. 3 Through him all things were made; without him nothing was made that has been made. 4 In him was life, and that life was the light of all mankind. 5 The light shines in the darkness, and the darkness has not overcome it.
Second passage: John 1:14
And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
The word = Christ
If you substitute "word" in John 1
In the beginning was Christ, and Christ was with God, and Christ was God. HE was with God in the beginning. Through HIM all things were made, with out HIM nothing was made that has been made. In HIM was life, and that life was the light of all mankind ("I am the light of the world" John 8:12)
In Genesis "Let us make man in OUR image".
That's basically how the church taught me of those scriptures.
Now, I'm not positive what you are asking but I think you are asking if "everything is the essence of God", and what the church teaches about it? Like basically is a chair, a car, or a marble an "essence of God?".
I know the creed states of Jesus is "of one essence with the Father through whom all things were made" which is a church teaching. I have not heard anything about "all things that were made" being an essence or part of God ever in Orthodoxy. I've only heard it as "things which God made" and not "things that are God's essence". However, I know that the Eucharist is considered God (the body and blood of whom is of one essence with the Father) which is also part of the creation which was transmuted.
The only way that I could PERSONALLY conclude this is to use the Eucharist as an example. The Eucharist is God because Jesus is of one essence. If any object of creation was really of one essence would it be considered as important as the Eucharist itself? Though I've never heard it in Orthodox teaching directly, I haven't witnessed candles, books, cars, food, or the church itself, even remotely held to the magnitude of the Eucharist which is of one essence.
