forbidden.

And these four causes are touched upon in Ps. 118:8, where it is
said: "The law of the Lord is unspotted," i.e. allowing no foulness
of sin; "converting souls," because it directs not only exterior, but
also interior acts; "the testimony of the Lord is faithful," because
of the certainty of what is true and right; "giving wisdom to little
ones," by directing man to an end supernatural and Divine.

Reply Obj. 1: By the natural law the eternal law is participated
proportionately to the capacity of human nature. But to his
supernatural end man needs to be directed in a yet higher way. Hence
the additional law given by God, whereby man shares more perfectly in
the eternal law.

Reply Obj. 2: Counsel is a kind of inquiry: hence it must proceed
from some principles. Nor is it enough for it to proceed from
principles imparted by nature, which are the precepts of the natural
law, for the reasons given above: but there is need for certain
additional principles, namely, the precepts of the Divine law.

Reply Obj. 3: Irrational creatures are not ordained to an end higher
than that which is proportionate to their natural powers:
consequently the comparison fails.

Whether There Is but One Divine Law?

Objection 1: It would seem that there is but one Divine law. Because,
where there is one king in one kingdom there is but one law. Now the
whole of mankind is compared to God as to one king, according to Ps.
46:8: "God is the King of all the earth." Therefore there is but one
Divine law.

Obj. 2: Further, every law is directed to the end which the
lawgiver intends for those for whom he makes the law. But God intends
one and the same thing for all men; since according to 1 Tim. 2:4: "He
will have all men to be saved, and to come to the knowledge of the
truth." Therefore there is but one Divine law.

Obj. 3: Further, the Divine law seems to be more akin to the
eternal law, which is one, than the natural law, according as the
revelation of grace is of a higher order than natural knowledge.
Therefore much more is the Divine law but one.

_On the contrary,_ The Apostle says (Heb. 7:12): "The priesthood being
translated, it is necessary that a translation also be made of the
law." But the priesthood is twofold, as stated in the same passage,
viz. the levitical priesthood, and the priesthood of Christ. Therefore
the Divine law is twofold, namely the Old L
