Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.

Paul never says that they will not be justified before God because they have not kept the law of righteousness in the commandments but because they have refused to believe the sacrament of the mystery of God, which is in Christ. For God has declared that they should be justified by Christ and not by the law, which may justify for a time, but not before God. Therefore those who keep the law are justified in time, not before God, because faith, by which they are justified before God, is not in them. For faith is greater than the law. The law pertains to us but faith pertains to God. The law has a temporary righteousness, but faith has an eternal one. When Paul says “all flesh” he means every human being … but when he says “in the flesh” he means those who are bound by sin. For just as righteousness makes them spiritual, so also sins make them carnal, and they take the name from the deed. By faith the law is abolished, and faith then follows. What then is this law through which he says that sin is made known? Made known how? It is evident that long before Moses the patriarchs were not ignorant of sin. Joseph was thrown into prison, albeit by the wickedness of others, and both the butler and the baker of Pharaoh were in prison because of their sins. In what way then did sin lie dormant? In fact, the law has three aspects to it. The first concerns the mystery of God’s divinity. The second is what is fitting according to natural law, which forbids sin. And the third is the deeds of the law, e. g., sabbaths, new moons, circumcision, etc. Here Paul refers to the natural law which was partly reformed and partly confirmed by Moses, which made sin known to all who were bound in wickedness…. The law shows the coming judgment of God and that no sinner will escape punishment, in case someone who has escaped for a time thinks that the law is an illusion. This is what the law shows: that sin will be dealt with by God. Commentary on Paul’s Epistles.
