You've surely noticed that, among worldlings, the word Holy is today frequently juxtaposed with various curse words and other profanations. The most frequent is the juxtaposition of Holy with a common curse word referring to feces. And of course the original Batman television series is known for Robin's constant juxtapositions of the word Holy with various profane absurdities, which though seemingly innocuous actually serve to make light of this tremendous word.
Whenever you hear this word juxtaposed in so perverse a fashion, do you ever correct the speaker by saying something like, "You know, those words have no business being said together"? I said this once to a Catholic friend. He was surprised at first, but then after he thought about it he came back later and said I was right, but that he'd never thought about it before. It was just habit, and he's since broken it.
We can do a good deed whenever we remind someone that the word Holy is never to be cheapened.
