Of God and His Creatures
That there is in God Active Power
As passive power, or passivity, follows upon being in potentiality, so
active power follows upon being in actuality; for everything acts by
being in actuality, and is acted upon by being in potentiality. But it
belongs to God to be in actuality; and therefore there is suitably
ascribed to Him active power, but not passive power.
Hence it is said: Thou art powerful, O Lord (Ps. lxxxviii, 9);
and Thy power and thy justice, O God, are even to the highest
heaven, in the wonders that thou hast made (Ps. lxx, 18, 19).
