If you've read L.M. Montgomery's work, you know that religion comes up pretty often, usually in a way that's irreverent toward minutiae but respectful overall. Most of her characters are Presbyterian, and characters' hangups over their differences with Methodists are played for comic effect, as are some anxieties about what is or isn't okay to think about on Sunday. But in serious moments, Christianity is taken seriously, and all this is just part of the fabric of life for the ridgepole-walking redhead. It doesn't seem to bother Sabbath-observing, kosher-keeping Henny. Fast-forward about eighty years, and much as I loved seeing my family's religious practices in the All of a Kind Family books, the Anne books felt just as much my own.
Religious differences don't have to be cataclysmic. That's all I'm saying.
