In the Nicene Creed, there is the part that says:
"…We believe in one Lord, Jesus Christ, the only Son of God, eternally begotten of the Father,** God from God, Light from Light, true God from true God**, begotten, not made, one in being with the Father…
In my CCD class, a boy asked about the part that I bolded and underlined, asking what this particular part meant. I explained how the Creed is the statement of our faith in a nutshell, and it was done to combat certain heresies of the time.
But I would like to go deeper and find out just what each phrase is defining. How is “true God from true God” different from “God from God”? And why did they find it necessary to add “Light from Light”?
