Whether the Old Law was good?

Objections

Objection 1 : It would seem that the Old Law was not good. For it is written (Ezech. 20:25): "I gave them statutes that were not good, and judgments in which they shall not live." But a law is not said to be good except on account of the goodness of the precepts that it contains. Therefore the Old Law was not good.
Objection 2 : Further, it belongs to the goodness of a law that it conduce to the common welfare, as Isidore says (Etym. v, 3). But the Old Law was not salutary; rather was it deadly and hurtful. For the Apostle says (Rm. 7:8, seqq.): "Without the law sin was dead. And I lived some time without the law. But when the commandment came sin revived; and I died." Again he says (Rm. 5:20): "Law entered in that sin might abound." Therefore the Old Law was not good.
Objection 3 : Further, it belongs to the goodness of the law that it should be possible to obey it, both according to nature, and according to human custom. But such the Old Law was not: since Peter said (Acts 15:10): "Why tempt you (God) to put a yoke on the necks of the disciples, which neither our fathers nor we have been able to bear?" Therefore it seems that the Old Law was not good.
