Or rather, parts of it, because it's rather long to be requiring high schoolers to read the whole thing. Maybe just Genesis? It would, of course, be taught as literature, in the same way as Homer's Odyssey. But there are so many things embedded in our culture that ultimately come from the Bible, it seems a shame that so few people actually read it. (It's also a shame that so few people actually read Homer's works, and so few people actually read Dante's Inferno, and so few people actually read Shakespeare.)
