It appears to be in St. Louis, yes.

At any rate, knowing where this girl went to high school tells me more about the O'Reilly lawsuit than I'd ever be able to figure out from 80 pages of depositions.
My son applied there and the interview was between two men from the board (it's a covenant school) and husband and me. They said that there would only be one question, "How do you know you're saved?" My husband is Catholic and a parochial school alum from the 60's, and given his uncertainty and guilt about just about everything theological, moral, and otherwise, he wasn't quite sure if he was saved---or would ever be saved no matter what they did. I had been to a fundamentalist Bible study but couldn't remember the verses that assured salvation. Needless to say, neither answer was the right one and our son was permanently "wait-listed". Guess that was the equivalent of always waiting at the Gate to Heaven with St. Peter--you can look in but you can never enter. (Or like being the SNL disco brothers in the disco line.)
At any rate, they pride themselves on their academic performance and many bright kids from very nice upper-middle-class go there. It is a very white-bread school. Kids behave no better there by virtue of being admitted or attending but parents are more confident in their children's behavior because they have a sense of security (or spiritual certainty) about the place.
My worst fears about the school, however, have been confirmed by the original thread post. Jeez--I couldn't even tell what the subject matter was! If this is a reflection of the intellectual growth that happens at Westminster Christian, I'm thrilled that my son didn't go there. (BTW, he ended up at a pagan school with a diverse bunch of liberals. He became a better writer than he had been, excellent public speaker, student government leader, and a committed conservative. The first thing he did when he got to college was join the College Republicans. It was obviously divine intervention that kept him out of the Christian school.)
