When I was early-teens (pretty much areligious[1]) some of the usual suspects came in to school and basically handed out handy-sized bibles and 'answered any questions' in their gentle happy-clappy version of a kind of missionary-style zeal. Somewhere I still have mine, I'm sure, but it's not where I immediately thought it might be (probably in a different pile of half-forgotten tomes, slid into a gap it nicely slots into) so who exactly these Gideon-maybes were I don't currently know.
I think I was mostly dissapointed that this was the
New Testament, only, as I clearly remember discovering when I had browsed through looking for the 'intetesting stuff'; which I later realised is probably OT, on the whole. I read what I got, though. Not sure I could ever quote chapter and verse[2], but I think I get the general gist of the bits that I do subscribe to, and it meshes well with the gist of any other 'decent' religion (also humanism, Bill And Ted, etc).
BTW, super-coincidental honourable mention goes to the
latest xkcd, in the context of where this thread's current conversation is going...
[1] I'd years before been registered as a Cub Scout as "'
CofE', I suppose", because they needed something to write in their little ledger, alongside emergency contact details, and in general the question didn't ever really come up because I could sing hymns in School Assembly as good (or as bad) as I could sing any other song they shone up on the OHP screen for hundreds of kids to attempt to reproduce synchronously if individually atonously.
