I'm the married mom of a 6.5 y/o ds - and we do not attend church.
That's a really good question.
Hi. I'd like to chime in just to say that I don't see how "social reasons" are such a bad reason to attend church. I would call it "community," though, and in my experience it's been really enriching for my life. I was raised Methodist by parents who were not especially religious, and having another social environment that was separate from my school life and friends was very valuable, particularly in the teen years. My parents have also been friends with a group of people from church for the last 30 years or so. My husband and I have 10- and 7-year old kids and started going to church about five years ago (and neither of us would consider ourselves super-religious--we wouldn't have started going if it weren't for the kids). It took a couple of years, but now I don't know what we'd do without our church community. Practically all of my close friends and not-so-close friends come from church--it's an amazingly smart, thoughtful, funny group of people overall.
For what it's worth, we also started taking the kids because we wanted them to be able to choose what they thought about God and religion as they grew up. In my experience, people who haven't grown up with some sort of consistent experience with church don't really have the information to make this choice. It's sort of like, say, growing up watching a normal amount of TV and then considering not having TV as an adult. You understand that some people don't have TVs and must have good reasons to, but you can't really envision or understand that decision because you ahve no experience with it. It's hard to take the option seriously. DOes that make sense? It's a pretty lame analogy, I know, but I know that while many of my friends who grew up going to church don't anymore, or go to a different kind of church, but I don't know anyone who grew up without any sort of church at all who consistently goes as an adult.
Gotta run to work now, but I did want to offer another point of view about the whole "social" thing.
I was raised as nothing.
I was raised an atheist and continue to be so. My DH is agnostic. We don't go to church obviously but we have created a strong community with people who share our interests. Some have the same religious beliefs as we do, others don't. We are very connected to extended family.
