aright, it makes us do freely those things that are becoming to
grace, and shun what is opposed to it.

Accordingly the New Law is called the law of liberty in two respects.
First, because it does not bind us to do or avoid certain things,
except such as are of themselves necessary or opposed to salvation,
and come under the prescription or prohibition of the law. Secondly,
because it also makes us comply freely with these precepts and
prohibitions, inasmuch as we do so through the promptings of grace.
It is for these two reasons that the New Law is called "the law of
perfect liberty" (James 1:25).

Reply Obj. 3: The New Law, by restraining the mind from inordinate
movements, must needs also restrain the hand from inordinate acts,
which ensue from inward movements.

SECOND ARTICLE [I-II, Q. 108, Art. 2]

Whether the New Law Made Sufficient Ordinations About External Acts?

Objection 1: It would seem that the New Law made insufficient
ordinations about external acts. Because faith that worketh through
charity seems chiefly to belong to the New Law, according to Gal.
5:6: "In Christ Jesus neither circumcision availeth anything, nor
uncircumcision: but faith that worketh through charity." But the New
Law declared explicitly certain points of faith which were not set
forth explicitly in the Old Law; for instance, belief in the Trinity.
Therefore it should also have added certain outward moral deeds,
which were not fixed in the Old Law.

Obj. 2: Further, in the Old Law not only were sacraments instituted,
but also certain sacred things, as stated above (Q. 101, A. 4; Q.
102, A. 4). But in the New Law, although certain sacraments are
instituted by Our Lord; for instance, pertaining either to the
sanctification of a temple or of the vessels, or to the celebration
of some particular feast. Therefore the New Law made insufficient
ordinations about external matters.

Obj. 3: Further, in the Old Law, just as there were certain
observances pertaining to God's ministers, so also were there certain
observances pertaining to the people: as was stated above when we
were treating of the ceremonial of the Old Law (Q. 101, A. 4; Q. 102,
A. 6). Now in the New Law certain observances seem to have been
prescribed to the ministers of God; as may be gathered from Matt.
10:9: "Do not possess gold, nor silver, nor money in your purses,"
nor other things which are mentioned here and Luke 9, 10. Therefore
