And, it works in so many ways in Elizabeth Scalia's (The Anchoress) latest at First Things. Here's a taste and then you can go enjoy it all.
This sister gave an example: “When we were in our habits, a fellow with an Italian ice barrow would always insist on giving us free ices, but why should he? Why shouldn’t we pay like anyone else? Why should we deprive him of his living because we were in a costume?”
Sister was operating under a willful delusion; she justified forsaking the habit with appeals to solidarity, compassion, and humility, but her story illustrated egoism and presumption. She bemoaned a possibility of cheating a man out of his wages. In fact, she wascheating that man, but not in the way she imagined.
The ice-barrow man was not giving sister a free ice because she wore a habit, but because a man who revered (or at least respected) God saw an opportunity to demonstrate his regard in a little way that St. Therese might have applauded.
