“My God can neither be imagined nor described. He is infinite. Tall or short, fat or thin, old or young, black or white. These are the human attributes that we try to apply to God into our limited minds.”

Part I, Prop. XXIX, Scholium (trans: Edwin Curley, London: Penguin, 1996)
Ethics (1677)

Context: I believe in recognizing every human being as a human being, neither white, black, brown nor red. When you are dealing with humanity as one family, there's no question of integration or intermarriage. It's just one human being marrying another human being, or one human being living around and with another human being.

Ode interview (2009)
Context: People like Thomas Aquinas would say we can't talk about God as a creator because we can only have in our heads the idea of a human creator and that can't apply to God. We can't even say that God exists because our notion of existence is too limited to apply to God. People were instructed to think about this in those terms.
