And God said,
Let there be light:
and there was light.
All Commentaries on Genesis 1:3 Go To Genesis 1
Ambrose of Milan
AD 397
God is the author of light, and the place and cause of darkness is the world. But the good Author uttered the word light so that he might reveal the world by infusing brightness therein and thus make its aspect beautiful. Suddenly then, the air became bright and darkness shrank in terror from the brilliance of the novel brightness.
