When I was growing up, I loved hearing my father talk about religion. It didn't happen very often, because my mother always seemed to get nervous and tried to change the subject, but it was from him that I first heard about a scholarly and philosophical side to religion. My childhood view of it was very matter-of-fact and unquestioned, so it was always thrilling to hear a more skeptical set of opinions. 

I've described myself as an atheist since I was sixteen, but whatever religious beliefs I had for a few years before then were indistinct and not very well thought-out. I haven't considered myself to be a Catholic since I was thirteen.
