Our potential

C S Lewis described the worth of souls with these words: "The load, or weight, or burden of my neighbor's glory should be laid daily on my back, a load so heavy that only humility can carry it, and the backs of the proud will be broken. It is a serious thing to live in a society of possible gods and goddesses, to remember that the dullest and most uninteresting person you can talk to may one day be a creature which, if you saw it now, you would be strongly tempted to worship. . . . It is in light of these overwhelming possibilities, it is with the awe and circumspection proper to them, that we should conduct all our dealings with one another, all friendships, all loves, all play, all politics. There are no ordinary people. You have never talked to a mere mortal. Nations, cultures, arts, civilizations--these are mortal, and their life is to ours as the life of a gnat. But it is immortals whom we joke with, work with, marry, snub, and exploit. . . . Next to the Blessed Sacrament itself, your neighbor is the holiest object presented to your senses." (From "The Weight of Glory," a sermon given at the Church of St. Mary the Virgin, Oxford.)
