You know, we should always watch our mouths because God is always listening. But have you ever let a curse fly out of your mouth in front of the wrong person? Kind of humiliating, isn’t it? Imagine what would happen if you cussed in front of … I don’t know, say … Mother Teresa of Calcutta. I have a friend who did just that! And what happened gives you an insight into one of the great souls of modern times, whose feast day was this past week on Sept. 5.

Mario Enzler, former Pontifical Swiss Guard:

“The first time I met Mother Teresa, she scared the heck out of me. This is the reason. As a Swiss Guard, when you get into trouble, you are entitled to some social service. I am in the kitchen — the reason why I chose to be in the kitchen is they were serving lentil soup, and you have to scoop the lentil soup and serve it to 250 people. I didn’t really like the smell. I said, ‘Let me just stay in the kitchen and wash pots. I don’t need to be here.’ And the sister said okay.

 “What they didn’t tell me was that they wanted their pots to be spotless, and they used pots that would turn black. You know when you fry turkey — those pots? And I was complaining. I was upset, I kid you not! At a certain point, I threw a temper tantrum. I threw the pot into this sink, and water came out — my pants, my underwear, my shoes were all soaking wet. I used bad words without knowing who was next to me. 

 “And this nun was taking glasses out of the cart. She was putting them on a tray that then will be pushed under an industrial dishwasher. Well, I didn’t recognize that nun. First of all — the Missionaries of Charity, they all look alike. They are all the same height, you know? So, when I saw a nun and then I looked again, she looked at me and it was Mother Teresa.
