LUCKY SEVERSON: The famous religious conversion stories are full of high drama: Saul's vision on the road to Damascus or Constantine's [vision of a] fiery cross in the sky. Modern-day religious conversions can seem tame by comparison, but tolerant attitudes toward faith-seeking have made them more common. Still, choosing a new religion is usually a major decision -- for converts and their families. In the first of a two-part series, our reporter, Stephen Dubner, himself a convert and author of the book TURBULENT SOULS, looks at the experience of John Curry, principal of a school for at-risk students in New York.

JOHN CURRY: I grew up in St. Louis, in the Bible Belt. My parents talked about religion constantly, they were in a Methodist Church ... they considered themselves born again and were very strict theologically.

RUTHIE PADOWER: I experienced Judaism in two opposite ways. At home, it was this very pleasant, defining part of who we were and then we lived in a town that was not heterogeneous at all. It was purely Christian, and so, I grew up very uncomfortable with my Judaism in that setting.

STEPHEN DUBNER: You met in college. Was the fact that you came from different religions an issue?

MS. PADOWER: Once we started thinking about living together and maybe marrying and having children, it was an issue because I wanted to raise my children Jewish, and I didn't want to raise my children in a house where Christmas was celebrated.

CURRY: Ruthie, at one point, said, well you can have a Christmas tree if you need it to be in the house ... but it will be your Christmas tree and the children and I will just consider that daddy's, and I thought, I'm gonna be sitting in the corner with my little Christmas tree. It was just ridiculous, and then I thought, well I'm gonna be like a stranger in my own family, and I couldn't really see how to resolve it at the time.

DUBNER: Did you think at all back then about converting?

CURRY: I think I did in vague ways, but I couldn't really imagine it. Not that it was something I would hate to do, but I guess I felt that [by] even saying it, I was gonna feel like a wannabe for someone else's culture.

LEWIS RAMBO (Author, UNDERSTANDING RELIGIOUS CONVERSIONS): The experience of conversion, I think, at its deepest level, is a profound and pervasive reorientation of one's entire life. Starting in many cases with self image -- Who am I as a human being? -- to, Who is God? What is the nature of reality?

RABBI MAGGIE WENIG: I think it's as significant a decision as choosing a partner to spend many years of your life with or deciding to have a child.

DUBNER: We are probably in a country and at a time when conversion is at an all time high. Conversion is rampant. Is that good?

RABBI WENNIG: I would have to say yes. But I believe that human beings long for meaning, a relationship with God, community, and are feeling an emptiness.

DUBNER: Tell me about this Christmas season visit to your sister's house in Seattle.

CURRY: At this particular Christmas service, they took a baby out of the congregation and put it in the manger for a Christian ceremony.

MS. PADOWER: And that night, I had a dream that I had a child and that they took my baby out of my arms and used him or her for their Jesus, and we couldn't get him back.

CURRY: I'd always had this idea that somehow I wanted Christmas in my family's life because, somehow, that would bring happiness to my children. And I had this horrible experience: my mother, sister, and father not getting along; me feeling watched by my parents to see if I would go up to the altar and profess my faith in Christ; conflicts around our children. ... I felt like there was this whole ball of tension and things I didn't know how to resolve. I was lying in bed, and I thought, you know, if I converted to Judaism this would just go away. And I said to Ruthie, "Maybe I should convert," and she said "Why would you want to do that?" My fear was that she would say, "That's wonderful," and I would feel this responsibility to follow through, and instead, she just put the breaks on.
