CTF 2026 - Session 3: Is God the Author of Sin?
Two difficult theological questions frame this conference session: Is God the author of sin, and do a believer's sins work together for good? Drawing on 1689 LBCF 3.1, Acts 2:23, Acts 17:28, and Romans 8:28, the session argues that God's comprehensive, eternal decree encompasses all things — including sin — without making God personally culpable for evil, because sin is a privation of good rooted in the creature's deformed nature rather than in God's infinitely good being. The session closes by showing from Romans 8:28, with support from Robert Haldane and Genesis 50:20, that God's overruling providence turns even the believer's own sins toward their ultimate good and his glory — not as license to sin, but as ground for humility, dependence, and hope.
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.
