Let me start by saying that I was taught by nuns from first through eighth grade at St. Mary's Byzantine Catholic School in Chicago's Back of the Yards neighborhood, the sisters of St. Basil.

Some of the sisters were great teachers, others were not. Some were wonderful human beings, others were not. But all of them were human beings. They were not caricatures or stereotypes, and they weren't cute little elements to put in an advertisement.

I'm not going to make a federal case here, but I am regularly saddened by the use of nuns in TV, a phenomenon that goes back at least as far as Sally Field's ridiculous "Flying Nun," back in the 1960s.

Most recently, there's a Glidden commercial, a cool, colorful way for the paint company to sell its wares with a great Electric Light Orchestra soundtrack. Smack dab in the middle is a group of nuns painting their convent, and then, they magically appear out in the open air, dancing, because, apparently, that's what nuns do when they finish painting.

Here's the Glidden spot I'm talking about:

It's easy to see it as innocuous, but I have a couple points:

Yes, there are nuns who still wear habits, but most do not wear the traditional garb. They are out in society, rather than cloistered as they do their work.

Two, nuns are spiritual women, like many spiritual people in our society -- some of whom do wear traditional garb. Imagine the same scene with dancing men in Hasidic clothing? How about women in Islamic veils?

You wouldn't see it. It would spawn protests at least (not something I'm recommending by any means).

But the trivialization of nuns as cartoon characters isn't seen as insulting to these women of faith.

It annoys me. Not to the level of organizing a protest or calling the Catholic League. I do enjoy a religious joke and I think that religion is a human thing that can be handled comedically. I'm hardly a prude in that department.

But Catholic nuns are not a joke. They're not a device for advertising. They're women who've dedicated their life to a spiritual mission.

All I ask is that their mission isn't obscured by the silly way they're presented on the small screen. There, end of rant.
