us an example; hence Augustine says in a
sermon (xxii de Temp.): "Man who might be seen was not to be
followed; but God was to be followed, Who could not be seen. And
therefore God was made man, that He Who might be seen by man, and
Whom man might follow, might be shown to man." Fifthly, with regard
to the full participation of the Divinity, which is the true bliss of
man and end of human life; and this is bestowed upon us by Christ's
humanity; for Augustine says in a sermon (xiii de Temp.): "God was
made man, that man might be made God."

So also was this useful for our _withdrawal from evil._ First,
because man is taught by it not to prefer the devil to himself, nor
to honor him who is the author of sin; hence Augustine says (De Trin.
xiii, 17): "Since human nature is so united to God as to become one
person, let not these proud spirits dare to prefer themselves to man,
because they have no bodies." Secondly, because we are thereby taught
how great is man's dignity, lest we should sully it with sin; hence
Augustine says (De Vera Relig. xvi): "God has proved to us how high a
place human nature holds amongst creatures, inasmuch as He appeared
to men as a true man." And Pope Leo says in a sermon on the Nativity
(xxi): "Learn, O Christian, thy worth; and being made a partner of
the Divine nature, refuse to return by evil deeds to your former
worthlessness." Thirdly, because, "in order to do away with man's
presumption, the grace of God is commended in Jesus Christ, though no
merits of ours went before," as Augustine says (De Trin. xiii, 17).
Fourthly, because "man's pride, which is the greatest stumbling-block
to our clinging to God, can be convinced and cured by humility so
great," as Augustine says in the same place. Fifthly, in order to
free man from the thraldom of sin, which, as Augustine says (De Trin.
xiii, 13), "ought to be done in such a way that the devil should be
overcome by the justice of the man Jesus Christ," and this was done
by Christ satisfying for us. Now a mere man could not have satisfied
for the whole human race, and God was not bound to satisfy; hence it
behooved Jesus Christ to be both God and man. Hence Pope Leo says in
the same sermon: "Weakness is assumed by strength, lowliness by
majesty, mortality by eternity, in order that one and the same
Mediator of God and men might die in one and rise in the other--for
this was our fitting remedy. Unless He was God, He would not have
brought a remedy; a
