 Only God’s most efficacious volition is that truly acting power (virtutem), which moves while not being moved, which rigorously speaking moves, which moves one body by means of (per) another, which moves the whole corporeal world, its parts, some by means of (per) others, and in this way He brings about (efficiat) every one of the natural effects that happens in even the most remote corners of the Universe by means of his sole immediate power.
