Gospel." Hence then the
New Law is in the Old as the corn in the ear.

Reply Obj. 1: Whatsoever is set down in the New Testament explicitly
and openly as a point of faith, is contained in the Old Testament as
a matter of belief, but implicitly, under a figure. And accordingly,
even as to those things which we are bound to believe, the New Law is
contained in the Old.

Reply Obj. 2: The precepts of the New Law are said to be greater than
those of the Old Law, in the point of their being set forth
explicitly. But as to the substance itself of the precepts of the New
Testament, they are all contained in the Old. Hence Augustine says
(Contra Faust. xix, 23, 28) that "nearly all Our Lord's admonitions
or precepts, where He expressed Himself by saying: 'But I say unto
you,' are to be found also in those ancient books. Yet, since they
thought that murder was only the slaying of the human body, Our Lord
declared to them that every wicked impulse to hurt our brother is to
be looked on as a kind of murder." And it is in the point of
declarations of this kind that the precepts of the New Law are said
to be greater than those of the Old. Nothing, however, prevents the
greater from being contained in the lesser virtually; just as a tree
is contained in the seed.

Reply Obj. 3: What is set forth implicitly needs to be declared
explicitly. Hence after the publishing of the Old Law, a New Law also
had to be given.

Whether the New Law Is More Burdensome Than the Old?

Objection 1: It would seem that the New Law is more burdensome than
the Old. For Chrysostom (Opus Imp. in Matth., Hom. x [*The work of an
unknown author]) say: "The commandments given to Moses are easy to
obey: Thou shalt not kill; Thou shalt not commit adultery: but the
commandments of Christ are difficult to accomplish, for instance:
Thou shalt not give way to anger, or to lust." Therefore the New Law
is more burdensome than the Old.

Obj. 2: Further, it is easier to make use of earthly prosperity than
to suffer tribulations. But in the Old Testament observance of the
Law was followed by temporal prosperity, as may be gathered from
Deut. 28:1-14; whereas many kinds of trouble ensue to those who
observe the New Law, as stated in 2 Cor. 6:4-10: "Let us exhibit
ourselves as the ministers of God, in much patience, in tribulation,
in necessities, in distresses," etc. Therefore the New Law is more
bur
