If you have a light, and the whole world should come to you in order to take light from it—the light itself does not diminish—and yet each person has it all. It is true that everyone participates more or less in this light, according to the substance into which each one receives the fire…. Each one carries his own candle, that is the holy desire, with which he receives this Sacrament.
–Saint Catherine of Siena (1347-1380
