You are the light of the world. A city set on a hill cannot be hidden. Nor do men light a lamp only to put it under a bushel basket; they put it on a stand where it gives light to all in the house. The Lord called his disciples the salt of the earth because they seasoned with heavenly wisdom the hearts of men, rendered insipid by the devil. Now he calls them the light of the world as well, because they have been enlightened by him, the true and everlasting light, and have themselves become a light in the darkness.
-- Saint Chromatius of Aquileia
