Madeline L'Engle writes in her autobiography that she didn't believe in God, but needed to act like she did in order to live a good life. So she went to church. I can't decide if this is necessary or not, if this makes any sense or not.

I do need church, but I don't need the Catholic Church. It hurts and disappoints me more than anything else. It's a lot like a friend you relied upon for a long time that you expected was one way, but then find out that it actually represents everything you hate. And I can't see past that.
