Transcript for New Reality Show Follows Young Women Thinking About Becoming Nuns
. We're back now at 7:42 with a reality show breaking new ground. It's about a group of young women thinking about becoming nuns. Call it reality meets spirituality. And Dan Harris explains. Women don't enter with halos. They don't come in holy. God called them from where they are, and all come from different backgrounds. It will be very difficult.

I think there is definitely a place for religion in television and in pop culture. It just needs to be done in a tasteful way. Reporter: Lifetime, hoping tonight's debut will score in the ratings, getting both the faithful and the doubtful to watch. For "Good morning America," Dan Harris, ABC news, New York. Just when you think you've seen it all. Yep. There's something else. The discernment phase. Yeah.
