I think creationism is, in a sense, a kind of category mistake, as if the Bible were a theory like other theories. Whatever the biblical account of creation is, it's not a theory alongside theories...So if creationism is presented as a stark alternative theory alongside other theories I think there's just been a jarring of categories. It's not what it's about.
And the telling quote of his is where he points out, "My worry is creationism can end up reducing the doctrine of creation rather than enhancing it." And there it is... teaching creationism as a science actually diminishes its scope, and I agree with this. Not that I think it means that science is less than religion, but that trying to put a religious ideal into a scientific context ... misses the point. In fact, it misses the point so much, it disqualifies it as the original religious object.
And I go back to the point I keep trying to point out time and time again: The Separation Between Church and State isn't there to protect the state, it's there to protect the church(es). I find it marvelous and appalling that the very people who would suffer the most by breaking down this barrier are the ones pushing for it to be broken.
