rity are not sufficient.

_On the contrary,_ Our Lord said (Matt. 22:40): "On these two
commandments dependeth the whole Law and the prophets."

_I answer that,_ Charity, as stated above (Q. 23, A. 1), is a kind of
friendship. Now friendship is between one person and another,
wherefore Gregory says (Hom. in Ev. xvii): "Charity is not possible
between less than two": and it has been explained how one may love
oneself out of charity (Q. 25, A. 4). Now since good is the object of
dilection and love, and since good is either an end or a means, it is
fitting that there should be two precepts of charity, one whereby we
are induced to love God as our end, and another whereby we are led to
love our neighbor for God's sake, as for the sake of our end.

Reply Obj. 1: As Augustine says (De Doctr. Christ. i, 23), "though
four things are to be loved out of charity, there was no need of a
precept as regards the second and fourth," i.e. love of oneself and
of one's own body. "For however much a man may stray from the truth,
the love of himself and of his own body always remains in him." And
yet the mode of this love had to be prescribed to man, namely, that
he should love himself and his own body in an ordinate manner, and
this is done by his loving God and his neighbor.

Reply Obj. 2: As stated above (Q. 28, A. 4; Q. 29, A. 3), the other
acts of charity result from the act of love as effects from their
cause. Hence the precepts of love virtually include the precepts
about the other acts. And yet we find that, for the sake of the
laggards, special precepts were given about each act--about joy
(Phil. 4:4): "Rejoice in the Lord always"--about peace (Heb. 12:14):
"Follow peace with all men"--about beneficence (Gal. 6:10): "Whilst
we have time, let us work good to all men"--and Holy Writ contains
precepts about each of the parts of beneficence, as may be seen by
anyone who considers the matter carefully.

Reply Obj. 3: To do good is more than to avoid evil, and therefore
the positive precepts virtually include the negative precepts.
Nevertheless we find explicit precepts against the vices contrary to
charity: for, against hatred it is written (Lev. 12:17): "Thou shalt
not hate thy brother in thy heart"; against sloth (Ecclus. 6:26): "Be
not grieved with her bands"; against envy (Gal. 5:26): "Let us not be
made desirous of vainglory, provoking one another, envying one
another"; against discord (1 Cor. 1:10): "That you all speak the sa
