“It is a great and very rare thing for a man, after he has contemplated the whole creation, physical and nonphysical, and has discerned its mutability, to pass beyond it, and, by the continued soaring of his mind, to attain to the unchangeable substance of God, and, in the height of contemplation, to learn from God Himself that none but He has made all that is not of the divine essence.”

Augustine The City of God
