I agree completely with Wolfgang's reasons for the choices he made regarding his children's schooling. This idiomatic cultural baggage is the lingua franca we must deal with. The mythological and linguistic elements must be taken into account to raise a child with adequate cultural literacy. It's something that English-as-second-language speakers also have to sort out, even if they don't practice the dominant religion among English speakers.

I would not go so far as to send my children to a religious school, but make a point of discussing the occasions when they or I myself recognize some new (to them) use of biblical or liturgical references in everyday usage. I don't know a great deal about a lot of religions, but we also have discussed (at least in passing) what we know about other religions or spiritual practices going on around us. We try to be open minded and look to good sources when the need arises. I have a few reference books on the subject of World Religions in the shelves next to where the kids do their homework.
