Sam2 there is a disagreement between the Rambam and Ravaad if believing in corporeality makes one into a heretic. The Rambam says yes. The Ravaad says no, however even according to him that does not mean that such a person is not going to Gehenom for such a belief. Read the various commentators. The Ravaad says that there were great people who made such MISTAKES based on verses and midrashim that cause mistaken ideas when taken literally. (In other words, they are not understood correctly.)
You make is sound like there is some valid opinions about this out there. GOD FORBID. First off, the greatest philosophers, jewish and gentile, agreed that the first cause is in NO way physical. And besides, the Rambam codified the 13 cardinal beliefs (codified, not made them up) and the majority of the greatest men in all later generations accepted it as did the masses of Jews the world over. One of the beliefs is that Hashem is not corporeal. So I would advise you to be careful what you write.
