12. God is immaterial; that is to say, his nature differs from all that which we call matter: otherwise he could not be immutable, for he would be subject to the transformations of matter.
God has not a form appreciable to our senses: if he had, he would be matter. We say, the hand of God, the eye of God, the mouth of God, because men knowing him only by themselves, takes themselves as a term of comparison of all that which they comprehend not. Pictures representing God as an old man with a long beard, covered with a mantle, are ridiculous: they have the disadvantage of lowering the Supreme Being to the level of poor humanity. It is but one step from that to endow him with the passions of humanity, and to make of him a jealous and angry God.
