Saadia Gaon introduced ex nihilo creation into the readings of the Jewish bible in the 10th century CE in his work "Book of Beliefs and Opinions" where he imagines a God far more awesome and omnipotent than that of the rabbis, the traditional Jewish teachers who had so far dominated Judaism, whose God created the world from pre-existing matter. Today Jews, like Christians, tend to believe in creation "ex nihilo," although some Jewish scholars recognise that Genesis 1:1 recognises the pre-existence of matter to which God gives form.
