to speak of having friendship
for wine or for a horse.

Yet neither does well-wishing suffice for friendship, for a certain
mutual love is requisite, since friendship is between friend and
friend: and this well-wishing is founded on some kind of
communication.

Accordingly, since there is a communication between man and God,
inasmuch as He communicates His happiness to us, some kind of
friendship must needs be based on this same communication, of which
it is written (1 Cor. 1:9): "God is faithful: by Whom you are called
unto the fellowship of His Son." The love which is based on this
communication, is charity: wherefore it is evident that charity is
the friendship of man for God.

Reply Obj. 1: Man's life is twofold. There is his outward life in
respect of his sensitive and corporeal nature: and with regard to
this life there is no communication or fellowship between us and God
or the angels. The other is man's spiritual life in respect of his
mind, and with regard to this life there is fellowship between us and
both God and the angels, imperfectly indeed in this present state of
life, wherefore it is written (Phil. 3:20): "Our conversation is in
heaven." But this "conversation" will be perfected in heaven, when
"His servants shall serve Him, and they shall see His face" (Apoc.
22:3, 4). Therefore charity is imperfect here, but will be perfected
in heaven.

Reply Obj. 2: Friendship extends to a person in two ways: first in
respect of himself, and in this way friendship never extends but to
one's friends: secondly, it extends to someone in respect of another,
as, when a man has friendship for a certain person, for his sake he
loves all belonging to him, be they children, servants, or connected
with him in any way. Indeed so much do we love our friends, that for
their sake we love all who belong to them, even if they hurt or hate
us; so that, in this way, the friendship of charity extends even to
our enemies, whom we love out of charity in relation to God, to Whom
the friendship of charity is chiefly directed.

Reply Obj. 3: The friendship that is based on the virtuous is
directed to none but a virtuous man as the principal person, but for
his sake we love those who belong to him, even though they be not
virtuous: in this way charity, which above all is friendship based on
the virtuous, extends to sinners, whom, out of charity, we love for
God's sake.
