Perjury

Perjury is the sin of swearing a false oath — calling on God to witness a statement that is untrue, or a promise one does not mean to keep. The foundational prohibition in Scripture is stated in Leviticus 19:12: "'You shall not swear by my name falsely, and profane the name of your God. I am Yahweh.'" The text treats the offense as double: a wrong against the neighbor whom the lie injures, and a profanation of God's own name, since the oath enlisted that name as guarantor. The prophets take up the same charge. Jeremiah 7:9 lists swearing falsely alongside stealing, murder and adultery in an indictment of covenant-breaking (Jeremiah 7:9), and Zechariah 5:4 pictures a curse that goes out from Yahweh and settles in the house of "him who swears falsely by my name," destroying it. Malachi 3:5 places perjurers among those against whom God himself will be "a swift witness," and ties the offense to a root charge: "and don't fear me," says Yahweh of Armies.

Scripture's narratives show what perjury does in a courtroom. In 1 Kings 21:13 two hired witnesses testify that Naboth "cursed God and the king," and on that false testimony he is carried out and stoned — a judicial murder engineered through perjured evidence. Matthew 26:59 records that the chief priests, the elders and the whole council "sought false testimony against Jesus, that they might put him to death," and Acts 6:13-14 describes false witnesses brought against Stephen. In each case the lie is spoken in a legal setting, and an innocent person dies. Isaiah 48:1 adds a subtler form of the same offense: a people who "swear by Yahweh's name" but "not in truth, nor in righteousness," invoking God's name while living contrary to it.

The New Testament restates the prohibition and then presses further. Matthew 5:33 cites the traditional teaching, "You shall not make false vows, but shall perform to the Lord your vows," and the same discourse goes on to redirect hearers away from oath-taking altogether toward simple truthfulness (Matthew 5:34-37). First Timothy 1:9-10 places "perjurers" among the lawless and insubordinate for whom the law was given, alongside liars, treating false swearing as one of the marks of conduct "contrary to the sound doctrine."

Traditions differ chiefly over what the Sermon on the Mount requires of oath-taking, not over whether perjury is grave. Jewish law has long distinguished several forbidden categories — the vain oath, the false oath, and the oath to do evil — grounding the prohibition in the third commandment and in Leviticus 19:12. Among Christians, Anabaptist and Quaker bodies have read Matthew 5:34-37 as an absolute prohibition of oaths, while Catholic, Orthodox, Lutheran and Reformed teaching has generally permitted oaths in judicial settings, reading Jesus as condemning the evasive oath-practice of his contemporaries rather than oath-taking as such, and pointing to instances where God swears by himself or an apostle calls God as witness (Romans 1:9). What the traditions hold in common is the substance of the offense: to swear falsely by God's name is to make God a party to a lie.
