"there is in him no real relation to the creature, although there is a relation of the creature to him, that of effect to cause."

"God does not act through an intervening action which is understood as proceeding from God and terminating in the creature, but his action is his substance and whatever is in him is wholly outside the genus of created existence by which the creature is related to God."
