The Ten Commandments was required viewing every year for CCD class when I was young. It was so ingrained that at the first CCD class one year when I was in fourth grade, the nun asked the class who parted the Red Sea, and Albie Rosar with a straight face answered, "Charlton Heston."
I went to Catholic school and the nuns arranged field trips for us to see it in downtown Pittsburgh at the Warner Theater. I'll never forget the experience.
