Almighty and eternal God,
Brightness of faithful souls,
you brought the Gentiles to your light,
and made known to them him who is the true Light,
and the bright and morning Star.
Fill the world with your glory,
and show yourself by the radiance of your light to all nations;
through Jesus Christ our Lord. Amen.
