There must be some variety in them, after all, this song which was made the Pop Top 40 when I was 16 was recorded by a Nun named Sister Janet Mead. Any nun who can produce music like this is OK in my book. (Sorry, imbed has been disabled again.)
I am a Protestant but I have nothing but respect for a woman who would dedicate her life to God the way many nuns do. The way they are often treated on Saturday Night Live skits and movies is a disgrace. These women deserve more dignity then they are getting. It wasn't always like this.
Remember The Singing Nun?
My favorite movie involving nuns, other than The Sound of Music, is The Lilies of the Field where Sidney Poitier played a shiftless drifter who was unwittingly recruited by some Nuns to build a chapel, and while he felt that he was being taken advantage of as he was working without pay, he came to love these women of God and found direction and meaning in his life that had been missing. Doesn't sound like much of movie, but it has a lot of heart.
