ID is not Creationism and not a Christian movement (for example
David Berlinski is a secular Jew). It's an evidential approach that basically tries to answer the question of what is designed, - not who, when, why, where and how. Which is why the movement is not Christian. Because the Bible does tell us who, why, when, where and how. And so while there are Christians within the intelligent-design movement, the movement itself is not Christian.
