The Lord is my light and my salvation; whom shall I fear? How great was that servant who knew how he was given light, whence it came, and what sort of man he was when he was favored by that light. The light he saw was not that which fades at dusk, but the light which no eye has seen. Souls brightened by this light do not fall into sin or stumble on vice. Our Lord said: Walk while you have the light in you. What other light did he mean but himself? For it was he who said: I came as a light into the world, so that those who have eyes may not see and the blind may receive the light. The Lord then is our light, the sun of justice and righteousness, who has shone on his Catholic Church spread throughout the world. The prophet spoke as a figure of the Church when he cried: The Lord is my light and my salvation; whom shall I fear?
