tion 1: It would seem that charity demands of a man to show his
enemy the signs or effects of love. For it is written (1 John 3:18):
"Let us not love in word nor in tongue, but in deed and in truth."
Now a man loves in deed by showing the one he loves signs and effects
of love. Therefore charity requires that a man show his enemies such
signs and effects of love.

Obj. 2: Further, Our Lord said in the same breath (Matt. 5:44): "Love
your enemies," and, "Do good to them that hate you." Now charity
demands that we love our enemies. Therefore it demands also that we
should "do good to them."

Obj. 3: Further, not only God but also our neighbor is the object of
charity. Now Gregory says in a homily for Pentecost (In Evang. xxx),
that "love of God cannot be idle for wherever it is it does great
things, and if it ceases to work, it is no longer love." Hence
charity towards our neighbor cannot be without producing works. But
charity requires us to love our neighbor without exception, though he
be an enemy. Therefore charity requires us to show the signs and
effects of love towards our enemies.

_On the contrary,_ A gloss on Matt. 5:44, "Do good to them that hate
you," says: "To do good to one's enemies is the height of perfection"
[*Augustine, Enchiridion lxxiii]. Now charity does not require us to
do that which belongs to its perfection. Therefore charity does not
require us to show the signs and effects of love to our enemies.

_I answer that,_ The effects and signs of charity are the result of
inward love, and are in proportion with it. Now it is absolutely
necessary, for the fulfilment of the precept, that we should inwardly
love our enemies in general, but not individually, except as regards
the mind being prepared to do so, as explained above (A. 8).

We must accordingly apply this to the showing of the effects and
signs of love. For some of the signs and favors of love are shown to
our neighbors in general, as when we pray for all the faithful, or
for a whole people, or when anyone bestows a favor on a whole
community: and the fulfilment of the precept requires that we should
show such like favors or signs of love towards our enemies. For if we
did not so, it would be a proof of vengeful spite, and contrary to
what is written (Lev. 19:18): "Seek not revenge, nor be mindful of
the injury of thy citizens." But there are other favors or signs of
love, which one shows to certain persons in particular: and it is not
