Danny Olinger | Meredith G. Kline's Biblical-Theological Reading of the Book of Revelation
In this episode, Camden Bucey speaks with Danny Olinger, General Secretary of the OPC Committee on Christian Education, about his new book Christ and His Church-Bride: Meredith G. Kline's Biblical-Theological Reading of Revelation (Reformed Forum). Olinger traces how Kline's covenantal and redemptive-historical reading of Revelation portrays the church's transformation into the radiant Bride of Christ, moving from imperfection and suffering in the present age to consummate glory in the new creation. The discussion unfolds key themes of recapitulation, the conflict between Babylon and the Bride, and the covenantal drama of creation to consummation. Through rich historical and exegetical reflection, Olinger shows how Kline weaves together Genesis, Daniel, Zechariah, and Revelation to present a unified vision of redemptive history centered on Christ's victory and the Spirit's work in the church. The conversation is both theologically rigorous and pastorally hopeful—reminding listeners that Christ reigns now, the church's pilgrim identity is secure, and the gospel's progress continues unthwarted by the powers of this world.

Jim Cassidy | The Seed of Abraham: Christ in the Patriarchs and the Promise
Dr. James Cassidy speaks at the Reformed Forum Annual Theology Conference, held at Lakeland Church in Gurnee, Illinois on September 27, 2025. The lecture, titled "The Seed of Abraham, Christ in the patriarchs and the promise" by Dr. James Cassidy, addresses the common theological perception that New Testament authors, particularly the Apostle Paul in Galatians 3, give a "surprise ending" to the Old Testament, seemingly reading it against its original intent. Dr. Cassidy argues against this view by showing that the Abrahamic Covenant is fundamentally a covenant of grace, centered on Christ as the singular "offspring" of promise. He explains that the promise is both individual (Christ himself) and collective (all those redeemed through him from every nation), a subtlety Paul rightly handles without misinterpreting Genesis. Crucially, the address highlights that the subsequent giving of the Mosaic Law 430 years later did not and could not annul the original promise of justification by faith, thereby maintaining the primacy and immutability of God's covenant of grace.

Lane Tipton | The Seed of the Woman: Christ in Creation and the Fall
Dr. Lane Tipton speaks at the Reformed Forum Annual Theology Conference, held at Lakeland Church in Gurnee, Illinois on September 27, 2025. Dr. Tipton presents Jesus Christ as the "mountain ascending mediator" and the promised seed of the woman from Genesis 3:15. Dr. Tipton argues that God's plan for redemption is framed by the concept of a holy mountain dwelling, beginning with heaven itself and its earthly counterpart, the Garden of Eden. After Adam's fall and subsequent exile from the holy mountain, God announced the first promise of the gospel—that the seed of the woman would crush the serpent's head. This salvific ascent was foreshadowed throughout the Old Testament on key mountains (Ararat, Sinai, Moriah, and Zion), all pointing to the final ascent of Christ. Through his sacrifice, Christ successfully ascended to the heavenly mountain, providing covering for sin, overcoming the devil, and bringing his people to see God in perfected worship and everlasting beatitude.
