We say that Christ, to Whom be glory, is “Light of Light.” Does this mean that the Light came from another Light? Is one of these lights the light that was at the beginning, which is mentioned at the beginning of the Book of Genesis?

The answer

Certainly not. “Light of Light,” is because God is light. His nature is light, and He dwells in light. God is not material or corporeal; He is all pure light.

“Light of Light” indicates that He is pure light. Christ says that He is from the Father, meaning that He is of the nature and essence of the Father. This is the meaning of “Light of Light.”
