In the New Testament, “law” most often refers to the Mosaic law given through Moses, though it can also mean Scripture more broadly or a governing principle in a given context. The New Testament teaches that the law is holy and good, yet unable to justify sinners, and that its goal is fulfilled in Christ.
“Law” in the New Testament usually means the Mosaic law, though it may also refer to Scripture or to a ruling principle in context.
“Law” in the New Testament commonly refers to the Mosaic law given through Moses, though some passages use the term more broadly for the Old Testament Scriptures or more narrowly for a principle operating in human experience. The New Testament presents the law as holy, righteous, and good because it comes from God, yet it also teaches that fallen sinners cannot be justified by keeping it. Jesus did not treat the law as evil or obsolete; rather, he fulfilled it and brought its purpose to completion. Apostolic teaching shows that the law exposes sin, bears witness to God’s standards, and served a preparatory role in redemptive history, but justification and new life come through faith in Christ, not through works of the law. Christians therefore read the law through its fulfillment in Christ, while carefully distinguishing what Scripture clearly teaches from broader questions about how Old Testament commands apply under the new covenant.
In the Gospels, Jesus affirms the authority of God’s law while also exposing hearts, correcting misuse, and declaring his fulfillment of the Scriptures. In Romans and Galatians, Paul explains that the law reveals sin and guards God’s people in redemptive history, but it cannot produce righteousness before God. Hebrews and related New Testament writings place the Mosaic covenant in relation to Christ’s better covenant and priesthood.
Second Temple Judaism held the law in high honor as the covenant charter of Israel. By the time of the New Testament, many Jews understood law-keeping as central to covenant faithfulness, which helps explain the intensity of apostolic debates over Gentile inclusion and justification. The early church therefore had to distinguish the law’s continuing witness to God’s character from its non-saving role under the new covenant.
In Jewish usage, Torah could mean instruction, teaching, or the law of Moses, and the New Testament sometimes reflects that broad range. The apostles’ discussions of circumcision, food laws, and covenant boundaries must be read against that Jewish background, especially in debates over Gentile believers and table fellowship.
The main Greek word is nomos, which can mean law, custom, principle, or a legal standard depending on context. In passages about Israel’s covenant, it commonly corresponds to the Hebrew Torah, meaning instruction or law.
The New Testament’s teaching about the law protects the gospel from legalism and also protects holiness from antinomianism. It shows that God’s moral will is real and binding, but that righteousness before God comes through Christ alone. The law therefore functions as witness, revealer of sin, and guide to understanding the need for grace.
The New Testament presents law as objectively good but limited in what it can accomplish because of human sin. In that sense, the issue is not a flaw in the law itself but the inability of sinful people to keep it perfectly. The gospel resolves this problem by providing in Christ both atonement and the new life needed for obedient faith.
The word “law” is used in several senses in the New Testament, so context must determine whether a passage refers to the Mosaic law, Scripture as a whole, or a principle at work in experience. Readers should also avoid collapsing all Old Testament commands into one category without distinguishing moral, ceremonial, and covenantal functions. The New Testament clearly rejects justification by works of the law, but Christians continue to differ on the exact continuity of particular Mosaic regulations.
Evangelical interpreters generally agree that the law cannot justify and that Christ fulfills it. They differ, however, on how the Mosaic law relates to the believer’s life under the new covenant: some stress strong continuity in the moral law, while others emphasize fulfillment in Christ and the new covenant’s governing ethic. The common ground is that salvation is by grace through faith and that obedience flows from redemption, not toward it.
This entry does not support legalism, covenantal works-righteousness, or the claim that believers are justified by law-keeping. It also does not erase the moral authority of Scripture or make obedience optional. The New Testament upholds both grace and holiness, with Christ as the fulfillment and center of God’s redemptive purpose.
Understanding the New Testament’s use of “law” helps believers read Scripture carefully, avoid legalism, and appreciate the freedom and responsibility of life in Christ. It also clarifies why Christians still learn from the Old Testament while no longer living under the Mosaic covenant as a covenant of obligation.
