From The Days of Vengeance, page 554
“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, or else a horror and a corruption such as you now meet, if at all, only in a nightmare. All day long we are, in some degree, helping each other to one or the other of these destinations. It is in the 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…. Next to the Blessed Sacrament itself, your neighbour is the holiest object presented to your senses. If he is your Christian neighbour, he is holy in almost the same way, for in him also Christ vere latitat – the glorifier and the glorified, Glory Himself, is truly hidden.”
