There are no ordinary people. You have never talked to a mere mortal. Nations, cultures, arts, civilization—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—immortal horrors or everlasting splendors.

This does not mean that we are to be perpetually solemn. We must play. But our merriment must be of that kind (and it is, in fact, the merriest kind) which exists between people who have, from the outset, taken each other seriously—no flippancy, no superiority, no presumption. And our charity must be a real and costly love, with deep feeling for the sins in spite of which we love the sinner—no mere tolerance or indulgence which parodies love as flippancy parodies merriment. Next to the Blessed Sacrament itself, your neighbor is the holiest object presented to your senses. If he is your Christian neighbor he is holy in almost the same way, for in him also Christ vere latitat—the glorifier and the glorified, Glory himself, truly is hidden.

From The Weight of Glory and Other Addresses by C.S. Lewis
