It's a natural for Leah to shift to Christianity/Catholicism, and to raise her daughter in a traditional group that is a little more love centered than what she was raised in. Then there's the freedom and lack of control, compared to Scientology.
But since I was raised Catholic, even though it was a relatively liberal dose compared to a few friends who went to Catholic school, Catholicism was still a trip, complete with irrational and unnecessary fears they impose on children, some by parents but more in religious education.
Leah's daughter may not be subjected to a lot of that and actually, a lot has changed since I was raised. American Catholics are especially liberal. You won't find as much self-flagellation going on over contraception or premarital sex compared to the old days. Even while I grew into adolescence, they kind of threw out the idea of roasting your sins off in purgatory, along with the Latin Mass. Now it's more unless you murder someone, it's a straight shot to heaven. If you're a Catholic, you're in like Flynn, and we know that even Mother Teresa was riddled with doubts, so doubt and even apostasy is not a huge problem. "Go in peace," as is said at the end of Mass.
My father was the stricter Catholic in our family and after I was off to college it was like, "You're an adult now and free to choose." I really liked that. In retrospect, I found the Catholic trip more confusing and irrational than rewarding and comforting. On balance, it provoked more fears, confusion and guilt than joy and love. I was off to college and I shed that cuckoo like a soiled pair of underwear, but it sticks with you too, for years, and I regret that my parents imposed it on me, mostly because their parents imposed it on them.
Even though Scientology took on religion as a disguise, I don't think it would be a bad idea for an ex-member to take a breather from religion, and to consider what it's all about anyway. Sure, religions may provide community, and answers about why we're here (to be in that particular religion and become enlightened, usually) and where we go after we're dead. But we are not living in the same world as when most of these religions sprang up. For example, we no longer conduct human and animal sacrifices to appease God and avoid crop failure.
