In serving spiritual demands, it became weak and even hostile to them. The Mosaic Law, given to determine the action of the will, could only prove more clearly the inner division and weakness of fallen man. It also awakened in him a thirst for the help of grace. This law helped the natural law of man's conscience. By positive external punishments it restrained man's sinful inclinations, and by rewards it encouraged the fulfillment of the good. But the weaknesses of the flesh, the inborn inclinations, and acquired habits of sin became so customary and constant that the Apostle directly calls them, taken together, the law of sin. According to the chief place of their activity, he calls them the law of the flesh, the law of the members, which opposes the law of the mind, or conscience. The opposition of this law to the law of the mind is so strong that man does what he does not will. For what he wills, he does not find sufficient strength in himself. Therefore the Apostle cries out on behalf of all suffering mankind: "O wretched man that I am! Who will deliver me from this body of death?" The Western Church, following the opinion of Augustine, Ambrose, and others, confirmed by the canons of the Council of Trent, applies the state of man described above to regeneration. Yet even among Western interpreters, some, for example Calmet, Allioli, and Bisping, rely on the opinions of Chrysostom, Theodoret, Theophylact, and other Eastern Fathers. They find it more consistent to see here the state of man before regeneration.
