2LCF Chapter 8 - Of Christ the Mediator, Part 2
The incarnation of the Son of God — his taking to himself a true and complete human nature — is the greatest of all gospel mysteries and the life and soul of the church. Working through paragraphs one, two, three, seven, and nine of the Second London Confession chapter eight, this study examines the timing, manner, and extent of the Son's assumption of humanity, arguing that the incarnation was neither a subtraction from deity nor an addition to it, but a terminative assumption by which the eternal Son united human nature to his own divine person in the hypostatic union. The full extent of that assumption — body, reasonable soul, human will, human affections, and the common sinless infirmities of our nature — is not a speculative nicety but a soteriological necessity: what is not assumed is not healed.
2LCF Chapter 8 - Of Christ the Mediator, Part 4
The person of the Lord Jesus Christ — his true humanity, sinlessness, and mediatorial office — is examined through paragraphs 2, 3, and 7 of the 1689 London Baptist Confession of Faith chapter 8. The session works through the Virgin birth by the power of the Holy Spirit, the essential properties and common infirmities of Christ's assumed human nature, his sinlessness according to that nature, and the role of the Holy Spirit in equipping him for his mediatorial task. Paragraph 7's doctrine of the communicatio idiomatum is then treated, establishing what may and may not properly be said of Christ given the hypostatic union of two natures in one person.
2LCF Chapter 8 - Of Christ the Mediator, Part 3
The incarnation of the Son of God — that the eternal, divine Son took to himself a true and complete human nature without ceasing to be God — stands at the centre of the Christian religion and is inseparable from the doctrine of salvation. This confession study works through 2LCF Chapter 8, paragraphs 2 and 7, first clearing away eight historical errors about what the incarnation is not (mutation, docetism, a heavenly body, a bodyless appearance, an animal soul without a human soul, a mixing of natures, a divestiture of divine attributes, and a Nestorian conjunction of persons), then positively establishing the language of assumption, union, and incarnation as the church's consistent witness from the apostolic era forward. The Son did not subtract from nor add to himself; he took to himself that which he was not while remaining fully what he eternally is, and the Trinity — Father, Son, and Spirit — acts undividedly in this work, though it terminates on the Son alone.
2LCF Chapter 8 - Of Christ the Mediator, Part 1
What does it mean to confess that Jesus Christ is very God and very man, and why does the precision of that confession matter for eternal life? This introductory session on 2LCF Chapter 8 surveys the doctrine of Christ the Mediator by establishing both the necessary posture and the interpretive rules required for sound Christology, then sets out seven reasons why the study of Christ stands at the center of all Christian theology. The session moves from the scope of Scripture as Christ-centered revelation, through the connection of eternal life to a right knowledge of Christ, to the comprehensiveness of all redemptive benefits being located in union with Him, calling the hearer to pursue a high Christology as the only safe and saving confession.
Of Christ the Mediator 1 (2LCF 8)
The person and work of Christ as mediator stands at the center of Christian theology, as this study of 2nd London Baptist Confession chapter 8 makes clear. Working through all ten paragraphs of the chapter in overview, the session traces the pre-temporal appointment of Christ as mediator in the covenant of redemption, the historical stages of his mediatorial work, and the necessity of his threefold office as prophet, priest, and king. Particular attention falls on paragraph 2's account of the incarnation — the eternal Son taking true human nature with all its essential properties yet without sin — and paragraph 7's careful rule for reading Scripture passages that attribute what belongs to one nature to the other, guarding against both a divinized humanity (Lutheran ubiquitarianism) and a humanized deity. Hearers are called to hold fast the church's historic confession of Christ as one person in two natures, whole, perfect, and distinct, without conversion, composition, or confusion.
The Cross of Christ in the Book of Acts, Part 1
What does the book of Acts reveal about the cross of Christ? This sermon works through Acts 2:22–23 and supporting passages in Acts 3, 4, and 20 to establish four of six planned headings on the cross: divine purpose (the cross was decreed in eternity past by the triune God), divine promise (the Old Covenant prophets announced the suffering Christ throughout redemptive history), divine providence (God brought about His eternal plan through the lawless hands of human agents), and divine performance (the one who shed His blood on Calvary was very God of very God, as Acts 20:28 declares). The sermon closes with a direct application to the Lord's Supper observed that evening, exhorting believers to prepare by meditating on these doctrinal realities rather than by anxious self-examination, and calling unbelievers to repent and trust Christ before the wrath of God abides on them.
