The flesh, from being the instrument of the spirit, became its master. It even drew the spiritual faculties into devising various means to satisfy its needs. It became weak in serving spiritual demands, and even hostile to them.
The Mosaic Law, given to define the action of the will, could only reveal more clearly the inward division and impotence of fallen man. It could also awaken in him a thirst for gracious help.
This Law assisted 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 good.
But the weaknesses of the flesh, inborn inclinations, and acquired habits of sin became so usual and constant that the Apostle directly calls them, taken together, the law of sin.
From 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 want. For what he does want, he does not find sufficient strength within himself.
Therefore the Apostle cries out on behalf of all suffering humanity: "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 decrees of the Council of Trent, applies the condition described above to regeneration.
Yet even among Western interpreters, some, such as Calmet, Allioli, and Bisping, rely on Chrysostom, Theodoret, Theophylact, and other Eastern Fathers. They find it more consistent to see here man's condition before regeneration.
