Christ is the LIGHT. God said... let there be LIGHT.
Genesis 1:1 and John 1:1 start with the same exact phrase, "In the beginning."
" In the beginning God created the heavens and the earth. "
vs
"In the beginning was the Word, and the Word was with God, and the Word was God."
This shows us that the Logos was present in Genesis 1:1 which means Christ is ETERNAL. You are saying that the darkness was present, but NOT the Logos. That isn't just wrong, it's blasphemy.
