TREATISE ON THE LAST END (Questions -5)
Since, as Damascene states (De Fide Orth. ii, 12), man is said to be
made in God's image, in so far as the image implies "an intelligent being
endowed with free-will and self-movement": now that we have treated of
the exemplar, i.e. God, and of those things which came forth from the
power of God in accordance with His will; it remains for us to treat of
His image, i.e. man, inasmuch as he too is the principle of his actions,
as having free-will and control of his actions.
