Whether every law is derived from the eternal law?

Objections

Objection 1 : It would seem that not every law is derived from the eternal law. For there is a law of the "fomes," as stated above (Question [91], Article [6]), which is not derived from that Divine law which is the eternal law, since thereunto pertains the "prudence of the flesh," of which the Apostle says (Rm. 8:7), that "it cannot be subject to the law of God." Therefore not every law is derived from the eternal law.
Objection 2 : Further, nothing unjust can be derived from the eternal law, because, as stated above (Article [2], Objection [2]), "the eternal law is that, according to which it is right that all things should be most orderly." But some laws are unjust, according to Is. 10:1: "Woe to them that make wicked laws." Therefore not every law is derived from the eternal law.
Objection 3 : Further, Augustine says (De Lib. Arb. i, 5) that "the law which is framed for ruling the people, rightly permits many things which are punished by Divine providence." But the type of Divine providence is the eternal law, as stated above (Article [1]). Therefore not even every good law is derived from the eternal law.
