2LCF Chapter 8 - Of Christ the Mediator, Part 4
Chapter 8 of the 1689 London Baptist Confession sets forth the person and work of Christ the Mediator, and this study works through its latter paragraphs (4–10) covering the historical description of Christ's obedience, the specific operation of His atoning work, the retrospective application of redemptive benefit to Old Covenant saints, the communication of idioms, and the effectual application of redemption to the elect. The confession grounds definite atonement, active and passive obedience, and penal substitutionary atonement in Christ's willing entrance into the state of humiliation and His perfect fulfillment of the law, establishing the foundation for the confession's later treatment of justification by faith alone. The threefold office of Christ as prophet, priest, and king is shown to be not an imposition on Scripture but its exegetical fruit, meeting precisely the threefold need of God's people for revelation, reconciliation, and kingly rule.
2LCF Chapter 8 - Of Christ the Mediator, Part 3
The sinlessness of Christ, the efficient and instrumental causes of the incarnation, and the hypostatic union are examined through a clause-by-clause exposition of 2LCF Chapter 8, paragraph 2, with supporting analysis of paragraphs 3 and 7. The confession's language — 'yet without sin,' 'conceived by the Holy Spirit,' 'of the seed of Abraham and David,' 'without conversion, composition, or confusion' — is unpacked against the background of patristic Christology, Chalcedonian definition, and Reformed theological precision. The ministry of the Holy Spirit throughout the entire mediatorial life of Christ is recovered as an often-neglected dimension of Christology. Incarnational and interpretive rules drawn from paragraph 7 equip hearers to handle Scripture passages that appear to diminish Christ's deity, by distinguishing what is predicated of a nature from what is predicated of the one person according to a nature.
2LCF Chapter 8 - Of Christ the Mediator, Part 5
The work of Christ as Mediator — his active and passive obedience, definite atonement, and threefold office as prophet, priest, and king — is the subject of this exposition of 2 London Baptist Confession of Faith Chapter 8, paragraphs 4 through 10. The confession traces Christ's voluntary humiliation, his satisfaction of divine justice as a propitiation, and the retroactive efficacy of that work for Old Covenant saints who looked forward to him through promises, types, and sacrifices. Paragraph 8's teaching that Christ certainly and effectually applies redemption to all for whom he obtained it grounds the assurance of salvation entirely in the sovereign purpose of God rather than foreseen conditions in the sinner. The threefold office — prophet to instruct the ignorant, priest to reconcile the alienated, king to subdue and preserve the unwilling — frames the believer's comprehensive dependence on Christ alone.
The Necessity of Christ's Passion
Matthew 16:21–23 presents the first formal announcement of what Christ himself calls a divine necessity: he must go to Jerusalem, suffer at the hands of the elders and chief priests, be killed, and be raised on the third day. The sermon traces this necessity through the covenant of redemption, the Old Testament prophetic witness — Psalms 22, 69, and 110, Isaiah 52–53, Daniel 9, Zechariah 9–14 — and a series of informal anticipations across Matthew's Gospel. Peter's sharp rebuke is examined as a representative failure to grasp the messianic agenda of a suffering Servant, and Christ's equally sharp response — 'Get behind me, Satan' — is shown to be the definitive affirmation that substitutionary curse-bearing is non-negotiable: error here is not a skin disease but a disease at the heart. The congregation is urged to hold fast to the doctrine of Christ crucified and risen as the only stable ground of perseverance in the Christian life.
2LCF Chapter 30 - Of the Lord's Supper
The Lord's Supper is a divinely instituted ordinance of the New Covenant, not a repeated sacrifice but a perpetual memorial of Christ's once-for-all offering upon the cross. This confession study works through 2LCF Chapter 30 paragraph by paragraph, exposing the errors of Roman Catholic transubstantiation and Lutheran consubstantiation on Christological grounds — to predicate ubiquity of Christ's humanity is to deny true humanity — while recovering the Calvinian understanding of Christ's real spiritual presence by the Holy Spirit. The chapter is shown to be comprehensive: institution, nature, celebration, elements, and recipients of the supper are each addressed. Worthy receivers feed spiritually upon Christ crucified and all the benefits of his death; the supper functions as a means of grace confirming faith, nourishing the soul, and promoting obedience.
2LCF Chapter 8 - Of Christ the Mediator, Part 1
Chapter 8 of the 1689 London Baptist Confession opens with the pre-temporal appointment of Christ as mediator in the covenant of redemption, then moves to the historical stages of that mediatorial work, beginning with the incarnation. The confession affirms that the Son of God, consubstantial and co-eternal with the Father, took on true human nature — with all its essential properties and common infirmities, yet without sin — so that two whole and distinct natures are inseparably united in one person: the hypostatic union. Drawing on John 1, Hebrews 2, 4, and 7, Galatians 4, and the Chalcedonian Definition of 451, the study traces the biblical and creedal foundations of Reformed Christology, and shows how the confession's language connects the Reformed Baptist tradition to the settled Christological consensus of the ancient church.
The Discourse on God's Salvation, Part 1
Jesus answers Nicodemus's question — 'How can these things be?' — by pointing to three realities: his own incarnation as the one who descended from heaven, the Old Testament typology of the bronze serpent in Numbers 21, and the necessity of his crucifixion as the antitype to whom sinners must look in faith. The sermon works through John 3:11–15, examining Christ's authority to speak of heavenly things, the doctrine of the hypostatic union and the communication of idioms, and the parallel between Israel's look-and-live prescription in the wilderness and saving faith in the crucified Son of Man. The application is direct: the antidote to sin is not moral reformation but faith in the lifted-up Christ, who alone secures justification and eternal life for believing sinners.
The Third Missionary Journey, Part 6
Acts 20:28–31 records the Apostle Paul's pastoral charge to the Ephesian elders at Miletus — a charge that functions as the first pastors' conference in the new covenant era. The passage demands that elders take heed to themselves and to all the flock, that they shepherd the blood-bought church of God, and that they remain vigilant against both external persecution and internal doctrinal corruption. The theological weight of the phrase 'the church of God which He purchased with His own blood' opens into a precise treatment of the communication of idioms, establishing that the divine and human natures of the one person of Christ are the ground on which Scripture can speak of God's own blood. Ministers are called to feed the flock with the whole counsel of God, warned that savage wolves and ambitious false teachers will arise, and exhorted to watch and warn with the same tear-stained fidelity that marked Paul's three years in Ephesus.
The Second Missionary Journey, Part 1
Acts 15:36–16:5 records the opening of Paul's second missionary journey — beginning with a sharp contention between Paul and Barnabas over John Mark, continuing through Paul's recruitment and circumcision of Timothy in Lystra, and concluding with a summary report of churches strengthened and growing daily. The sermon argues that God's sovereign providence overruled the division between two godly men to send out two missionary teams, and that Timothy's circumcision was a strategic pastoral act entirely consistent with Paul's settled rejection of Judaizing. Throughout, the exposition presses the congregation toward a recovery of faithful, word-centered ministry as the only legitimate means of church growth and stability.
Of Christ the Mediator 2 (2LCF 8)
The person and work of Christ as Mediator, as confessed in chapter 8 of the 1689 London Baptist Confession of Faith, is the most central locus in all of Christian theology — to be wrong here is damnable. This session surveys paragraphs 3 through 10 of that chapter, tracing Christ's anointing and suitability for office, the active and passive obedience by which He fully satisfied divine justice, the retrospective application of His redemption to the elect of all ages under the old covenant, the communication of idioms in His two natures, and the effectual application of salvation to His people by His Spirit and Word. The threefold office of prophet, priest, and king supplies precisely what the elect need in their ignorance, alienation, and inability — and no other mediator may share or transfer any part of that office.
2LCF Chapter 8 - Of Christ the Mediator
What is Christology, why does it matter, and how does the 1689 London Baptist Confession of Faith frame it? This introductory session works through John 17:3, Luke 24, John 20, Acts 5, 1 Corinthians 2, Colossians 1, and related texts to establish four grounds for the importance of Christology: its relation to Scripture, to preaching, to salvation, and to practical Christian living. The confession's account of Christ as mediator — truly God, truly man, two natures inseparably united in one person without conversion, composition, or confusion — is introduced as the doctrinal framework for the series. Hearers are called to approach the study of Christ's person and work not with cold detachment but with the highest reverence and the utmost joy, because eternal life itself consists in knowing the only true God and Jesus Christ whom he has sent.
