How have others that are not religious themselves go about introducing a general understanding of the basics to kids that haven't really experienced any religion? I am struggling with a good way to do it - my kids have a vague idea of Jesus as being similar to Father Christmas, from school I think, a really dodgy few bible stories they got from Veggie Tales and they have been to my MIL's catholic church a few times (eldest was baptised, if that's what catholics call it, I am really not well informed)... they still call churches castles which i thought was cute when thy were little, but at 7 and 5 I think I ought to be giving them more information.
What has brought this on is that the other day we walked past the local church near my mother's home - a gloomy smog-darkened affair, with the vicar standing outside handing out leaflets. My 5 year old son tugged on my arm and whispered 'mummy, is that the dark lord and his dark castle?' - which at the time had me giggling, but later struck me that even though my own parents had no religious beliefs, I read the bible and learned a fairly large amount from school about Christianity as well as other religions. My kids aren't getting that at school as they are in the USA school system, which isn't C of E. I don't know how to tell them anything without sounding disrespectful or frivilous, or putting my own slant on things. I've tried saying things like 'that's not a castle, it's a church, it's a place that some people go to because they are religious and they believe it is God's house', but it always sounds wrong to me... my husband is a devout atheist (that must be an oxymoron?!) so I can't get much help from him on the subject, and if I were asked to give a religion it would of course be that of his Great Noodliness the FSM, but obviously I have no intention of confusing my kids like that and making it a joking matter to them.
So how have others approached it? Is there a way to help a child decide for themselves if they would like a religion, to explain it without making it clear that it is not my own beliefs?
Thanks for any ideas...
