Prothero may be overly sanguine about the workings of the U.S. court system. But even if he's wrong, this shouldn't stop schools from making some effort to teach the Bible. The study doesn't have to be mandatory. In a national school system overscheduled with basic skills, other topics such as history and literature deserve core status more than Scripture--provided that these classes address it themselves, where appropriate. But if an elective is offered, it should be twinned mandatorily with a world religions course, even if that would mean just a semester of each. Within that period students could be expected to read and discuss Genesis, the Gospel of Matthew, a few Moses-on-the-mountain passages and two of Paul's letters. No one should take the course but juniors and seniors. The Bible's harmful as well as helpful uses must be addressed, which could be done by acknowledging that religious conservatives see the problems as stemming from the abuse of the holy text, while others think the text itself may be the culprit. The course should have a strong accompanying textbook on the model of The Bible and Its Influence but one that is willing to deal a bit more bluntly with the historical warts. And some teacher training is a must: at a bare minimum, about their constitutional obligations.
And, oh yes, there should be one faith test. Faith in our country. Sure, there will be bumps along the way. But in the end, what is required in teaching about the Bible in our public schools is patriotism: a belief that we live in a nation that understands the wisdom of its Constitution clearly enough to allow the most important book in its history to remain vibrantly accessible for everyone.
So the question remains should we do it? I think that Van Biema is on the right track. Probably not mandatory, as long as history and lit classes at least deal somewhat with the biblical allusions and contexts, but it should be offered. But training and a good curriculum are essential.
