This is a fair summary of my attitude. I enjoy seders and a few other things, but I would not go out of my way to participate. My wife, which has no more religious faith than me, grew up in a household that had more rituals than mine and rather enjoys them. So, for example, she will light candles on some holidays and say the appropriate prayers. She doesn’t expect me to participate, and I have learned to avoid snide remarks.
I pretty much ignore all other rituals. Except for the ritual cannibalism and blood drinking by Catholics, which I find revolting–for the symbolism, not for the reality, which is harmless.
I grew up Catholic. I’m now somewhere on the agnostic/atheistic end of the scale, but I do miss the ritual and community aspects of it. Some things I still do, like Christmas trees and so on, because those were comforting parts of my childhood. I’d never be able to rejoin a Catholic church; my personal beliefs about human ethics and morality are too different. It would be nice to find a community group with a similar framework, minus the things that I can’t agree with.
