Tsadhe–Righteousness of the Law

The key word in the Tsadhe section of Ps 119 (verses 137-144) is “righteous”. Twice God is called righteous and three times God’s laws are called right or righteous:

137 You are righteous, LORD,
   and your laws are right.
138 The statutes you have laid down are righteous;
   they are fully trustworthy.

142 Your righteousness is everlasting
   and your law is true.

144 Your statutes are always righteous;
   give me understanding that I may live.

This theme of God’s laws being righteous regularly surfaces throughout the Psalm (see also verses 7, 62, 75, 106, 123, 160, 164, 172). But while it may make sense for us to speak of God being righteous, or of a person being righteous, what does it mean to call God’s law righteous? I’ll consider two possibilities briefly:

Law as the standard of righteousness

First, we could say that the law is righteous in that it defines a standard of righteousness. It reflects the nature and character of the righteous God. This fits in with the general observation that in this Psalm, the writer more or less conflates God with his law – the things he says about God’s law are also true of God. For example, when he says he delights in God’s law, he is also delighting in God. When he says God’s law is righteous, he is saying that every word that proceeds from a righteous God must by nature be righteous.

It poses an interesting question. Is something right because God commands it, or is it commanded because it is right? Similarly, is something wrong because God forbids it, or is it forbidden because it is inherently wrong? The fact that some of the Old Testament laws have been explicitly abrogated under the new covenant suggests the former is the case. God himself is the standard of what is right. If he forbids something, then doing it is not right. If later he permits the same thing (e.g. eating pork), the moral status of that action has changed.

Law as a means of attaining righteousness?

The relationship between the law and righteousness is something that Paul reflects on at length in Romans. If the law is the standard of righteousness, does it not follow logically that law-keeping is a means of attaining righteousness?

In some places Paul seems to suggest that this might be at least a theoretical possibility. For example:

For it is not the hearers of the law who are righteous before God, but the doers of the law who will be justified. (Rom 2:13)

But he goes on to make it abundantly clear that this never happens. In reality, the law simply reveals how far short we have fallen, highlighting our sin, and effectively condemning us.

For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin. (Rom 3:20)

We might expect that the gospel would make us righteous by enabling us to keep the law. But that isn’t how Paul explains it. We have a righteousness that is by faith, completely disconnected from our personal success at law-keeping.

For we hold that one is justified by faith apart from works of the law. (Rom 3:28)

So though we agree with the Psalmist that the law is righteous, because it is the words of the righteous God, we cannot look to it as our source of righteousness. Simon Ponsonby says that the function of the law is “SOS” – “Shows our sins” and “Shows our Saviour”. And this surely is the most valuable facet of the law of God – it points us to Christ (through the symbols and types of the ceremonial law), an it drives us to Christ (by revealing the full extent of our own shortcomings). In the New Covenant, delighting in God’s law means delighting in Christ.

For Christ is the end of the law for righteousness to everyone who believes (Rom 10:4)
