In what sense does the Mosaic law still speak to Christians today?
Question 01166
The New Testament is unambiguous that Christians are not under the Mosaic covenant. Galatians 3:24-25 states plainly that the law was a guardian until Christ came, “but now that faith has come, we are no longer under a guardian.” Hebrews 8:13 describes the old covenant as obsolete, growing old, and ready to vanish. Romans 7:4 tells believers they have died to the law through the body of Christ. These are strong statements, and they raise an obvious question: if the Mosaic covenant has been set aside as a covenant governing the believer’s relationship with God, does it still speak to Christians at all, and if so, how?
Why the Mosaic Covenant Was Always Temporary
The Mosaic covenant was never intended to be permanent. Jeremiah 31:31-33 anticipated a new covenant that would replace it, and the writer to the Hebrews quotes this passage at length (Hebrews 8:8-12) precisely to demonstrate that the Mosaic economy was always provisional. It was given to Israel as a nation, at a specific moment in redemptive history, for specific purposes: to govern the life of God’s covenant people in the land, to reveal the holiness of God and the sinfulness of humanity, and to function as a custodian pointing toward Christ (Galatians 3:24). When Christ came, the system the covenant embodied found its fulfilment and its terminus. The ceremonial law pointed to Him; He fulfilled it. The sacrificial system anticipated His death; He accomplished it. The covenant as a legal arrangement governing Israel’s relationship with God has been superseded by the better covenant of which He is the mediator (Hebrews 9:15).
The Threefold Distinction
Christian theology has traditionally divided the Mosaic law into moral, ceremonial, and civil categories. The moral law, most comprehensively expressed in the Ten Commandments, reflects God’s eternal moral character and continues to function as the standard of righteousness. The ceremonial law governed Israel’s worship, its sacrifices, its calendar, and its dietary regulations, all of which were fulfilled in Christ and no longer bind Christians as observances (Colossians 2:16-17; Hebrews 10:1). The civil law regulated the social life of Israel as a theocratic nation in the land and does not directly apply to Christians or to modern states, though its underlying moral principles continue to express God’s concern for justice and human dignity.
This threefold distinction is useful as a rough guide but needs to be handled with care, because the Mosaic law itself does not observe these boundaries with the tidiness the categories suggest. The prohibition of mixing fibres (Leviticus 19:19) sits alongside “love your neighbour as yourself” (Leviticus 19:18) in the same chapter. The categories are a later systematic framework imposed on material that does not always sort neatly. Used as a guide for understanding how different types of legislation relate to the Christian differently, they are helpful; treated as if the distinctions were clean and exhaustive, they can mislead.
How the Moral Law Continues to Speak
The moral law continues to function in Christian life in at least two ways. It reveals the character of God, who is unchanging, and therefore what He requires of those who bear His image. The commands not to murder, not to steal, not to commit adultery, to honour one’s parents are not arbitrary regulations tied to a particular covenant moment. They express what human beings, made in God’s image, are designed for. Jesus does not abolish these (Matthew 5:17) but deepens them, pressing into the heart-level reality behind the external command.
The moral law also functions as a standard that exposes sin. Paul says in Romans 3:20 that “through the law comes knowledge of sin,” and this function is not abolished. Before a person comes to Christ, the law’s demands show how far short of God’s standard they fall, contributing to the work of bringing them to recognise their need of a Saviour. For the believer, the law continues to inform the conscience of what genuine righteousness looks like, not as a means of earning standing before God but as a description of the life that the Spirit produces in those He indwells.
What Christians Are Not Doing
Christians are not observing the Sabbath as a binding weekly obligation in the Mosaic sense, though the one-in-seven pattern of rest has a creational foundation (Genesis 2:3) that the Mosaic law formalised. They are not keeping the Jewish dietary laws, which were ceremonial markers of Israel’s distinctness as a people and were explicitly set aside in the New Testament (Mark 7:19; Acts 10:15). They are not offering animal sacrifices, and they are not bound by the purity laws of Leviticus. These regulations belonged to a specific covenant with a specific people at a specific point in God’s redemptive programme, and the New Testament is explicit that they do not bind those who are in Christ.
The Law as Revelation of God’s Character
What continues beyond the Mosaic covenant is not the covenant itself but what the law reveals about God. His holiness, His justice, His compassion for the vulnerable, His hatred of deception and exploitation, His concern for the dignity of those made in His image: these do not change when the Mosaic covenant is superseded, because they are not products of that covenant. They are expressions of who God eternally is. The whole of the Torah continues to speak to the Christian in this sense: as a revelation of God’s character, as a record of His dealings with His people, as a preparation for Christ, and as a resource for understanding what faithfulness to God looks like in practice. It simply no longer functions as the covenant framework through which the believer’s standing before God is defined.
So, now what?
The Christian who reads the Old Testament law is not reading a document that has nothing to say to them. They are reading a revelation of God that speaks to their own nature as image-bearers, to the moral character of the God they worship, and to the history of redemption that reaches its fulfilment in Jesus. What they are not doing is asking whether they have kept the covenant, because they are not in that covenant. They are in a better one, established on better promises (Hebrews 8:6), secured by the perfect obedience of the One who did keep the law in their place.
