2LCF Chapter 25 - Of Marriage
The 1689 London Baptist Confession of Faith chapter 25 offers a concise yet comprehensive definition of marriage as a lifelong covenant between one man and one woman, established by God in creation for companionship, procreation, and the lawful expression of sexual relations. This study works through each paragraph of the confession's chapter on marriage, examining the monogamous nature of marriage, the major purposes for which it was ordained, and the lawful parties who may enter it. The session also draws on Westminster Confession chapters 24, paragraphs 5 and 6, together with Deuteronomy 24, Matthew 5 and 19, and 1 Corinthians 7, to argue that Scripture authorizes divorce on the grounds of porneia and desertion, and that a lawfully divorced innocent party is free to remarry. The Protestant 'permanence view' of marriage is examined and found to be both exegetically deficient and pastorally harmful to innocent parties whom God's own law was designed to protect.
The Seventh Commandment, Part 2
The seventh commandment's prohibition against adultery extends, by the interpretive principle of the Decalogue, to every form of sexual sin Scripture addresses. This study works through homosexuality, bestiality, unlawful divorce, immodesty, polygamy, prostitution, and lust — demonstrating from the Old and New Testaments that each represents a violation of God's creation ordinance for marriage. The study closes with the recognition that the law's exposure of sexual sin drives the believer back to the cross, where the imputed righteousness of Christ and free and sovereign grace provide both forgiveness and the motive for sanctification.
Restrictions on Levitical Priesthood
Leviticus 21–22 sets out restrictions governing the Levitical priesthood: whom priests may mourn, whom they may marry, what physical conditions disqualify them from service, who may eat from their food, and what animals are acceptable for sacrifice. The underlying logic in every category is the same — the holy God who dwells among his people demands a priesthood, a sacrifice, and a manner of worship that reflect his holiness and are not corrupted by defilement or defect. These chapters point typologically beyond themselves to the Lord Jesus Christ, who alone fulfils what the Levitical order only approximated: the perfect high priest who is holy, harmless, and undefiled, and the perfect sacrifice offered once for all. The superiority of the new covenant is seen precisely here — the exclusions of the old order (eunuchs, the maimed, the lame) give way to the great invitation of Christ to the broken and outcast to come to the wedding feast.
Exodus 20:14, the 7th Commandment, Part 2
Expounding the seventh commandment (Exodus 20:14), this study completes a survey of the sins the commandment prohibits — polygamy, prostitution, pornography, transvestitism, and transgenderism — before turning to the manner in which the commandment is violated: externally through the act, internally through lustful imagination, and verbally through corrupt speech. The Westminster Larger Catechism frames the duties required: chastity in body, mind, affections, words, and behavior. The threefold use of the law (civil, pedagogical, normative) is applied to contemporary sexual ethics, and 1 Corinthians 6:9-11 is held out as the ground of gospel hope: the same sinners who practiced these things were washed, sanctified, and justified in the name of the Lord Jesus.
The 7th Commandment, Part 1
The Seventh Commandment — 'You shall not commit adultery' (Exodus 20:14) — prohibits not only the specific act of adultery but subsumes all sexual sins under its scope, while positively requiring chastity and the promotion of righteous sexual ethics. This exposition establishes the basis of the commandment in the creational purpose of marriage (Genesis 2), the function of God's law as a revelation of his character, and the severe sanctions — capital punishment in Israel, present social consequences, and the final judgment of God — attached to its violation. The sermon then works through the prohibited acts: adultery, fornication, incest, rape (with careful exegesis of the contested cases in Deuteronomy 22), homosexuality, bestiality, unlawful divorce (tracing the lawful grounds of porneia and desertion through Deuteronomy 24, Matthew 19, and 1 Corinthians 7), and immodesty. Throughout, the law's severity is balanced by the gospel: 'such were some of you, but you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus.'
The Seventh Commandment
The seventh commandment, 'You shall not commit adultery' (Deuteronomy 5:18), governs not merely the act of adultery but the full range of sexual conduct God defines in Scripture. Preached against the backdrop of Canada's Bill C-4, this sermon grounds sexual ethics in the creation order of Genesis 2, expounds twelve prohibited acts — from adultery and fornication through homosexuality, transgenderism, and pornography — and confronts the state's attempt to criminalise biblical teaching on sexuality. The law is preached so that sinners will see their need for Christ, whose blood alone washes, sanctifies, and justifies those who come to Him in faith.
2LCF Chapter 25 - Of Marriage
The 1689 London Baptist Confession chapter 25 sets forth a comprehensive theology of marriage as a monogamous, creational institution between one man and one woman, ordained for companionship, procreation, and the prevention of sexual immorality. This study walks through each paragraph of the chapter, examining the biblical case against polygamy, homosexuality, bestiality, and unequal yoking, while grounding each prohibition in specific Old and New Testament texts. The two paragraphs on divorce and remarriage that the Westminster Confession adds but the 1689 omits receive extended treatment, with the conclusion that Scripture's exception clauses permit dissolution of the marriage bond in cases of adultery and desertion, without penalising the innocent party. Hearers are exhorted to treasure their spouses, pursue marriage only in the Lord, and rear their children in the fear of God.
The Instruction on Celibacy and Children
Matthew 19:10–15 presents two closely linked teachings: Christ's instruction on celibacy and His reception of little children. Against Rome's doctrine of clerical celibacy and any Protestant tendency to exalt singleness above marriage, the sermon argues that celibacy is a sovereign gift of God given to some, not a spiritual superior state to be mandated or celebrated above the married estate. The blessing of the children exposes the disciples' failure to understand that Christ receives the weak and dependent, and the passage calls fathers to the concrete duty of bringing their children to Christ through prayer, Scripture, and faithful church attendance.
The Instruction on Divorce, Part 2
Sexual immorality and willful desertion are the two lawful grounds for divorce recognized in Scripture, and this exposition of 1 Corinthians 7:10–16 establishes both the prohibition against divorce and the Pauline exception. Paul's instruction divides into two sections: the command to believing spouses not to separate, and the rule governing mixed marriages in which one partner is converted after the wedding. The sermon argues that when an unbeliever departs and dissolves the marriage, the believing spouse is released from bondage and may remarry, grounding that conclusion in the absence of a prohibition in verse 15, the consistent biblical assumption that lawful divorce permits remarriage, and the analogy with Matthew 19:9. Throughout, the original intent of marriage as a lifelong, one-flesh covenant is upheld as the governing norm, with the exceptions confirming rather than undermining that norm.
The Instruction on Divorce, Part 1
Matthew 19:7–9 presents a Pharisaic challenge to Jesus on the Mosaic permission for divorce, and this sermon works through that challenge under two heads: the Pharisees' objection and Christ's response. The exposition moves through Deuteronomy 24:1–4, demonstrating that its protasis (verses 1–3) assumes the legitimacy of divorce and remarriage, while its apodosis (verse 4) prohibits only return to a first husband — not remarriage as such. Drawing on Leviticus 21, Ezra, Jeremiah 3, and the Westminster Confession 24.5, the sermon argues that porneia (sexual immorality broadly construed) constitutes a lawful ground for divorce and remarriage, and that to forbid what God's law permits is both antinomian and a burden God never intended to lay on innocent parties.
The Descent into Idolatry
Romans 1:18–32 presents the universal condemnation of mankind, tracing the descent from the suppression of general revelation into full-blown idolatry and its attendant vices. The wrath of God is not an incidental doctrine but the necessary backdrop to the gospel: ungodliness precedes unrighteousness, and when God is rejected, judicial abandonment follows — God gives men over to the very sin they have chosen. Idolatry is not merely an ancient phenomenon but the root of every vice list Paul enumerates, and contemporary idols of false religion, mammon, and self demand the same vigilance the Apostle John commands: 'Little children, keep yourselves from idols.' The only antidote to idolatry is the gospel, in which the righteousness God demands is also the righteousness He supplies through faith in Jesus Christ alone.
The Seventh Commandment, Part 2
Matthew 5:31–32 sits within Jesus' exposition of the Seventh Commandment, where He corrects not the Mosaic legislation of Deuteronomy 24 but the Pharisaic distortion of it that permitted divorce for virtually any cause. The sermon argues that Jesus' exception clause — 'except for porneia' — establishes sexual immorality as the one lawful ground for divorce, and that the final clause of verse 32 ('whoever marries a divorced woman commits adultery') must be read as applying only to unlawfully divorced women, not as a universal prohibition on all remarriage after any divorce. Deuteronomy 24:1–4 is examined at length to demonstrate that remarriage after a lawful divorce was never treated as adultery under the Mosaic economy — a point confirmed by the death penalty for adultery in Leviticus 20 and Deuteronomy 22. The sermon closes with pastoral implications: upholding the sanctity of marriage as a creation ordinance, extending genuine gospel mercy to those who have sinned or been sinned against in divorce, and calling God's people to fidelity that surpasses the world's standards.
A Biblical View of Homosexuality
Scripture condemns homosexuality not as a cultural accident or genetic condition but as a transgression of God's creational order, a sin judged in Sodom, legislated against in the Old Covenant, and confirmed in the New Testament. This sermon works through four biblical categories — creation, Sodom and Gomorrah, Mosaic legislation, and New Covenant confirmation — to establish that homosexuality is a moral offense against the triune God, not merely a violation of Jewish or sectarian code. The consistent refrain of Scripture is that this sin, like all sins catalogued in 1 Corinthians 6, is answered by a real Savior who washes, sanctifies, and justifies sinners — making a properly biblical view of homosexuality the only view that can offer genuine hope to those in bondage to it.
