And God said,
Let there be light:
and there was light.
All Commentaries on Genesis 1:3 Go To Genesis 1
Augustine of Hippo
We ought to understand that God did not say “Let there be light” by a sound brought forth from the lungs or by the tongue and teeth. Such thoughts are those of persons physically preoccupied. To be wise in accord with the flesh is death. “Let there be light” was spoken ineffably.
