2LCF Chapter 23 - Of Lawful Oaths and Vows
The lawful use of oaths and vows — their definition, sanctity, necessary care, and required clarity — is examined through 2LCF Chapter 23 against the backdrop of three historical abuses: Roman Catholic monastical vows, state imposition on conscience, and the Anabaptist and Quaker rejection of oaths altogether. The chapter is read in full and then expounded paragraph by paragraph, demonstrating from Deuteronomy, Matthew 5, Matthew 26, and Hebrews 6 that oaths are a legitimate element of religious worship reserved for matters of weight and moment, taken only in the name of God with holy fear and reverence. The session concludes by connecting the call to truthfulness with the person of Christ, who as the only one who ever spoke in perfect truth, stands as the substitute for those who break their word.
The Lawful Use of Vows in Israel
Leviticus 27 addresses the Israelite practice of making vows to God — acts of religious zeal, often rash or imprudent, by which persons consecrated people, animals, houses, or land to the Lord. The chapter does not license vow-breaking but rather underscores the gravity of vowing by legislating a costly redemption mechanism, warning the would-be vower to count the cost before speaking. The sermon situates the passage within the 1689 LBCF chapter 23 framework distinguishing oaths from vows, then draws three applications against popish monastical vows, Protestant legalistic vows, and pietistic circumventions of God's law — all forms of man-made religion condemned repeatedly in Scripture.
2LCF Chapter 23 - Of Lawful Oaths and Vows
Second London Confession of Faith chapter 23 treats the doctrine of lawful oaths and vows, distinguishing Reformed Baptist practice from the Anabaptist rejection of oath-taking and from Roman Catholic monastical vows. The sermon argues that swearing by God's name is itself an act of religious worship — acknowledging his omniscience, omnipresence, and vindictive justice — and that Scripture warrants oaths in matters of weight and moment while condemning their careless everyday use. Matthew 5:33–37 is shown to address the abuse of casual, trivial oath-making rather than solemn oaths before lawful authority, as confirmed by Christ's own oath before the Sanhedrin, God's oath to Abraham, and Paul's repeated appeals to God as witness. The sermon closes by exposing popish monastical vows of celibacy, poverty, and obedience as superstitious devices of men that contradict Scripture's positive assessment of marriage, honest labor, and just remuneration.
The Third Commandment
The Third Commandment — 'You shall not take the name of the Lord your God in vain' (Deuteronomy 5:11) — grounds its prohibition and its positive demands in the theological weight of the divine name itself: God's name is the vehicle by which He reveals His nature, being, and attributes to His creatures, so every misuse is a direct offense against God. The sermon works through five concrete violations (blasphemy, false oaths, magic and sorcery, misapplication of providence, and misinterpretation of Scripture) before turning to the positive duties of reverent use, worshipful fear, and a sincere profession of faith matched by answerable conduct. Throughout, the law-gospel distinction is maintained: no sinner is accepted by God on the basis of keeping this commandment, but on the basis of Christ's perfect obedience rendered in the sinner's place; those united to Christ by grace through faith are then pointed back to the law as a rule of grateful living.
2LCF Chapter 23 - Of Lawful Oaths and Vows
Lawful oaths and vows, treated in 1689 London Baptist Confession chapter 23, are grounded in the third and ninth commandments and constitute genuine acts of religious worship — invoking God's omniscience, omnipresence, and vindictive justice as witness and judge. The confession distinguishes oaths (promises made to men before God) from vows (promises directed to God himself), insisting both require solemn care and plain sincerity without equivocation or mental reservation. Against Anabaptist denial and Roman Catholic abuse, the sermon defends the legitimacy of lawful oaths in matters of weight and moment, refutes the reading of Matthew 5 as a suspension of oath-taking, and condemns popish monastical vows — perpetual celibacy, professed poverty, and regular obedience — as superstitious snares without scriptural warrant. Hearers are called to prize truth-telling as a reflection of the character of God and to take every solemn oath with a full awareness of its theological gravity.
2LCF Chapter 23 - Of Lawful Oaths and Vows
What makes an oath lawful, and what does the Bible say about vows? Working through Chapter 23 of the 1689 London Baptist Confession of Faith, this study distinguishes between oaths (solemn promises made before God to men) and vows (solemn promises made directly to God), and defends the lawfulness of both against the Anabaptist refusal to swear. The Confession's four characteristics of lawful oaths — their nature as acts of worship, their sanctity as sworn in God's name alone, their solemnity requiring due consideration of weightiness, and their sincerity requiring plain speech without equivocation — are traced through Scripture and illustrated with examples ranging from courtroom testimony to marriage vows. The study closes by warning against rashly multiplying vows and condemning the Roman Catholic tradition of monastic vows as superstitious snares that mistake asceticism for holiness.
Judges 11:29-40
Judges 11:29–40 presents one of the most disputed passages in the Old Testament: Jephthah's vow and its fulfillment. This study argues, against the view that Jephthah's daughter was merely consecrated to perpetual virginity, that the plain meaning of the text — confirmed by the language of burnt offering, the grief of the father, the lamentation of the daughters of Israel, and the brevity of the narrative's account of her death — demands the literal interpretation that Jephthah carried out a human sacrifice. The vow is shown to be unnecessary, manipulative, presumptuous, and wicked, yet God's sovereign deliverance of Israel is not thereby frustrated, and Jephthah's presence in Hebrews 11 demonstrates that the sins of the godly do not utterly extinguish their faith. The episode ultimately points beyond Jephthah to the perfect Deliverer who, in Gethsemane, made no rash bargain with his Father but submitted in full obedience.
The Third Commandment: Oath-Taking
Jesus' instruction in Matthew 5:33–37 is not a universal prohibition against oath-taking but a condemnation of the Pharisaic practice of swearing by created things — heaven, earth, Jerusalem, one's own head — as a device to lend apparent solemnity to speech while evading accountability to God. The sermon exposes this abuse by tracing the Old Testament's positive teaching on oaths, demonstrating from Christ's own submission to adjuration in Matthew 26 and from Paul's sworn affirmations that lawful oath-taking remains valid. The corrective Jesus offers is the kingdom ethic of simple truthfulness: the citizen of Christ's kingdom needs no oath to be believed, because his yes is yes and his no is no, and any compulsion to pad speech beyond this reveals the depraved bent traced ultimately to the father of lies. The Sermon on the Mount, rightly understood, drives the hearer to the cross, where Christ — who honored every commandment and swore to his own hurt — provides the righteousness no oath-keeper can supply for himself.
