Where Scripture speaks of the world's creation, it is not plainly said whether or when the angels were created; but if mention is made, it is implicit under the name of "heaven," when it is said, "In the beginning God created the heavens and the earth."
Saint AugustineThe mind commands the body, and it obeys forthwith; the mind commands itself, and is resisted. The mind commands the hand to be moved, and such readiness is there that the command is scarce to be distinguished from the obedience. Yet the mind is mind, and the hand is body. The mind commands the mind to will, and yet, though it be itself, it obeyeth not. Whence this monstrous thing? and why is it?
Saint Augustine
