What does Paul mean by “works of the law”?

Romans 3:20 (ESV)

20 For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin.

In short

By works of the law Paul means

  1. the things that are done in obedience to the Mosaic law; or

  2. the markers that identify Jews.

Likely, by works of the law, Paul has in mind obedience to the prescriptions of the Mosaic law. The prescriptions of the Mosaic law are good works, and Paul is saying that no one will be righteous before God by performing good works. We can detect that works of the law refers to obedience to the prescriptions of the Mosaic law for two reasons.

First, we have textual evidence from Jewish sources prior to Paul that there were some Jews who thought by performing the works of the law, one would be righteous before God. Second, that the works of the law refers to the prescriptions of the Mosaic law aligns with the logic of Paul’s thought. For in Romans 2:13 Paul says that the doers of the law are justified before God. Then in Romans 3:9 he says that all are under the power of sin. Now he explains that by works of the law, no one will be justified. In other words, Paul is saying that if one could perform the law, one would be righteous, but we all sin, so no one can perform the works of the law and be righteous.

Others contend that when Paul refers to the works of the law, he has in mind Jewish boundary markers. These hold that God gave the Jews certain religious practices, which were meant to distinguish them from the Gentiles. These practices included circumcision, keeping the Sabbath, and certain dietary restrictions. Paul is saying that while there is nothing inherently wrong with these practices, the Jews mistakenly thought that one would be justified before God by doing them.

The problem with this view is that Paul’s overall argument in Romans up until this point is not that Jewish identity markers make the Jews no better off than the Gentiles. Rather, his point is that because both Jews and Gentiles are under the power of sin, the Jews are no better off than the Gentiles. In other words, the problem the Jews face is not misunderstanding the means of salvation, but the power of sin. Further, Paul says that boundary markers such as circumcision are only useful if one keeps the whole law, implying that the works of the law are not equivalent to activities such as circumcision.

In the end, when Paul says that no one is justified by works of the law, his point is that no one is justified by obeying the precepts of the law.

Interpretation 1:
Paul means the things that are done in obedience to the Mosaic law.

Summary:

God gave the Israelites the law, which expresses God’s will for human behaviour. Unfortunately, because humans are under the power of sin, humans are not able to obey the law. For this reason, no one will be justified by the works of the law.

We have a corrupt nature, which means we can never please God by our own power. We are under the control of sin so that our works never measure up to God’s standard. Of course, God knows this, and he offers to redeem our sinful nature through Jesus Christ.

  • Douglas Moo

  • Leon Morris

  • Thomas Schreiner

Minor differences:

Our authors agree that the works of the law refers to the deeds done in accordance with the Mosaic law.

Richard Longenecker explains the view clearly when he points out that according to Paul, those who obey the law will be declared righteous (Romans 2:13). In other words, the law prescribes how one ought to live in order to be righteous, so that if one obeys the prescriptions of the law, one is righteous. Now Paul says in Romans 3:20 that no one will be justified by works of the law, by which he means that no one is able to obey the deeds prescribed by the law.1

Leon Morris contends that Paul is not only opposing the Jewish view that one could maintain the law and therefore be righteous before God, but he is also saying that no works of any kind can make one righteous.2

Interpretation 2:
Paul means the markers that identify Jews.

Summary:

The Israelites were given distinctive ways of living out their covenant relationship with God. In particular, the Israelites marked themselves from Gentiles by circumcision, observing the Sabbath, and other rights. Paul explains that by following through on these distinctive markers, no Israelite will be justified before God.

Advocates:

  • James Dunn

  • Craig Keener

Minor differences:

Our authors agree that when Paul uses the phrase works of the law, he has in mind Jewish identity markers.

James Dunn’s position is more comprehensively maintained. According to Dunn, the Jews were given certain laws which marked them off as the distinct people of God. The laws of particular significance included circumcision, and certain food laws. 8 The Jews mistakenly believed that by obedience to these religious laws one maintained their covenant relationship with God, but Paul is explaining that this is not the case.

Craig Keener seems to agree with Dunn, but his reasons are vague. He simply contends that Jewish distinctiveness seems to be an important theme for Paul in this section.9
