God (n.) is immaterial, purely spiritual and intellectual. God is pure thought which is entirely incapable of performing any kind of physical, bodily action.
God (n.) is incapable of thinking of anything but himself. He is defined entirely as 'thought of thought' or 'thinking about thinking'.
God (n.) is necessarily independent of all else for his existence. He never changes or has any potential to change, never begins and never ends, and so is eternal, and cannot be bad (insofar as badness is 'lack' which he cannot possess).
God (n.) is not that which pushed existence into being but that which draws all things to himself and remains unaffected. God did not create the stars like baking a cake, but stars and the planets form and take their movement out of a spiritual desire to imitate God and to push forward in order to return to God.
God (n.) is pure thinking about itself and thus cannot know this physical world that we inhabit, he does not have a plan for us, and he is not affected by us.
God (n.) is the unmoved mover, or the prime mover which is to suggest that it is a cause not in the sense of providing the initial push (i.e. Is an efficient cause) but rather is a 'cause' in the odd sense that it is the purpose or the teleology or attraction of the movement (i.e. Is a final cause) much like a saucer of milk attracts a cat.
God (n.) is a prime mover unmoved (primum mobile immotum), a being incorporeal, indivisible, spaceless, sexless, passionless, changeless, perfect and eternal.
God (n.) is not an entity that creates, but he moves, the world; and he moves it not as a mechanical force but as the total motive of all operations in the world.
God (n.) is pure energy, not so much a person as a magnetic power.
God (n.) is a mover, but he moves the world as the beloved object moves the lover.
God (n.) is an existence, but not perhaps the simple and human god conceived by the forgivable anthropomorphism of the adolescent mind.
God (n.) is an entity whose only occupation is to contemplate the essence of things; and since he himself is the essence of all things, the form of all forms, his sole employment is the contemplation of himself.
God (n.) is without qualities. He never does anything; he has no desires, no will, no purpose. He is activity so pure that he never acts.
