Dr. Robert Letham joins Lane Tipton and Camden Bucey to discuss Dr. Letham’s recent book The Eternal Son (P&R Publishing). Their conversation presses into a simple but urgent claim: Christology is not a side department of theology—it is the living center. When the church loses clarity about who the Son is, the gospel itself becomes unclear because salvation depends on the identity of the Savior. They also explore why the church must listen carefully to the whole ecumenical tradition, especially the often-neglected debates after Chalcedon.

Dr. Letham explains why it matters that the acting subject in the Gospels is the eternal Son, who assumes a true human nature without change in his divine person. From there, they engage contemporary confusions—especially biblicism that isolates Scripture from the church’s confession—and they address the claim that Christ was “adopted” at the resurrection, showing how such proposals unravel both orthodox Christology and the gracious character of adoption for believers.

In this episode, Dan Ragusa speaks about Letters from America (Reformed Forum). Between 1935 and 1940, Cornelius Van Til (1895–1987) wrote twenty-four letters from America for the Dutch magazine De Reformatie at the invitation of its editor Klaas Schilder (1890–1952). Daniel Ragusa’s translation presents these letters in English for the first time.

Letters from America opens a window into a critical moment in Reformed history—when orthodox and confessional Presbyterianism in America was under siege from both modernism and the rising influence of Barthianism, which Van Til labeled “the new modernism.” Ragusa introduces these letters by situating them within the broader relationship between the Dutch Reformed in the Netherlands and the orthodox Presbyterians in America—a relationship that reaches back to the seventeenth century.

Van Til’s wartime-like correspondences—written in the heat of theological conflict—offer a firsthand account of the spiritual and ecclesiastical upheavals of the era. Through Van Til’s eyes, fixed steadfastly on his risen and reigning Lord, readers witness pivotal moments in American Presbyterian history, among them J. Gresham Machen’s trial, deposition, and sudden death; the founding of Westminster Theological Seminary and the evangelistic work of its graduates; and the formation of the Presbyterian Church of America and its subsequent renaming as the Orthodox Presbyterian Church.

These letters bring to life a pivotal chapter in the defense and development of the Reformed faith that helps us to make sense of our present ecclesiastical and theological landscape.

In this episode, we continue engaging Geerhardus Vos’s treatment of repentance and the righteousness of the kingdom. The discussion begins by clarifying the close relationship between faith and repentance: Both are saving graces, sovereignly gifted by God, inseparably joined in conversion, yet not identical. Faith uniquely receives and rests upon Christ for justification, while repentance—though necessary—never functions as the instrument of union with Christ or the ground of God’s verdict. This careful distinction protects the gospel from subtle moralism and keeps repentance in its proper place as fruit flowing from mercy apprehended in Christ.

Vos then situates repentance within Jesus’ proclamation of the kingdom: Repentance corresponds to the kingdom’s righteousness-aspect, just as faith corresponds to its power-aspect. Repentance is not a meritorious condition for entry, but the moral-spiritual “fitness” that belongs to life under God’s righteous reign. The episode explores Vos’s “vernacular of repentance” in the Gospels—regret, inner reversal, and outward turning—showing that biblical repentance is comprehensive, God-centered, and transformative. Far from mere remorse or isolated moral adjustment, repentance is a whole-life reorientation toward God, forming a people whose inner and outer life increasingly reflects the righteousness of the kingdom.

In this episode we welcome church historian Stephen O. Presley to explore the life, theology, and enduring relevance of Irenaeus of Lyons. Writing in the latter half of the second century, Irenaeus emerges not merely as a polemicist against Gnosticism but as a deeply pastoral theologian—one whose doctrine, biblical interpretation, and ecclesial commitments were inseparably bound to the life of the church.

Presley highlights Irenaeus’s vision of Scripture as a unified, Christ-centered story, summed up in his doctrine of recapitulation: All things find their meaning, coherence, and redemption in Christ, the true head of humanity. Against both ancient Gnosticism and modern disembodied spiritualities, Irenaeus affirms the goodness of creation, the integrity of the human person, and the necessity of catechesis rooted in the rule of faith. For today’s church—navigating doctrinal confusion, cultural fragmentation, and questions of discipleship—Irenaeus offers a compelling model of theological method that is biblical, confessional, pastoral, and profoundly Christ-centered.

Dr. Stephen O. Presley is Director of Education and Engagement and Senior Fellow for Religion and Public Life at the Center for Religion, Culture and Democracy and Associate Professor of Church History at Southern Seminary. He is the author of Irenaeus of Lyons: His Impact and Life (Christian Focus) and Cultural Sanctification: Engaging the World like the Early Church (Eerdmans).

In this episode of Christ the Center, Camden Bucey and Lane Tipton discuss a deceptively brief but theologically weighty section of Geerhardus Vos’s Biblical Theology, exploring Jesus’s critique of first-century Jewish ethics. Far from addressing merely surface-level moral failures, Vos shows that Jesus exposes a deeper religious collapse—one marked by practical deism and pervasive self-centeredness. When God’s glory is displaced as the center of ethical life, obedience becomes external, fragmented, and ultimately irreligious.

This conversation presses the listener to consider how these same distortions reappear across church history and into the present—whether in moralistic fundamentalism, liberal Protestant ethics, or debates surrounding the New Perspective on Paul. The antidote Vos commends is not tighter rules or refined casuistry, but a recovery of true religion: life coram Deo, grounded in union with Christ, animated by delight in God himself as our supreme reward. In Christ, obedience is restored to its proper place as worship, flowing from grace rather than self-reliance.

In this episode of Christ the Center, we welcome Josiah Leinbach to discuss William Whitaker’s A Disputation on Holy Scripture—a monumental sixteenth-century defense of sola Scriptura, newly edited and republished by Prolego Press. Written in 1588 against leading Roman Catholic theologians such as Robert Bellarmine, Whitaker’s work offers a comprehensive treatment of Scripture’s authority, canon, clarity, and sufficiency. Leinbach explains how Whitaker combined Renaissance humanism with scholastic rigor, engaging Scripture, church history, and patristic sources to show that Protestant convictions about Scripture were neither novel nor reactionary, but deeply rooted in the catholic tradition of the church.

The conversation also explores the modern relevance of Whitaker’s work—especially amid contemporary debates over authority, tradition, and ecumenism. Leinbach reflects on how advances in historical and textual scholarship have confirmed many of the Reformers’ arguments, while Rome’s own positions have shifted over time. Whitaker’s insistence on the perspicuity of Scripture, the singular infallibility of God’s Word, and the Spirit’s inward testimony offers not only apologetic clarity but deep pastoral comfort. This episode invites listeners to recover confidence in Scripture as God’s clear and sufficient means of revealing Christ to his people.

In this episode, Camden Bucey and Marcus Mininger reflect together on Resurrection and Redemption by Richard B. Gaffin Jr.—a work that has profoundly shaped Reformed biblical theology over the past half century. Rather than offering a technical review, the conversation unfolds as a guided meditation on the book’s central claim: Christ’s resurrection is not a theological afterthought but the controlling center of Paul’s soteriology and eschatology. Gaffin’s careful exegesis helps readers see how redemption is inseparable from resurrection life in union with the risen Christ.

This discussion is part of Reformed Forum’s broader effort to offer conversational commentaries on formative Reformed texts—books that have formed us as pastors and theologians. Bucey and Mininger highlight why Resurrection and Redemption remains so enduringly fruitful: It teaches the church to think biblically about salvation, not as a static transaction, but as participation in the resurrected life of Christ. The result is theology that serves the pulpit, strengthens assurance, and orients the Christian life toward the hope of glory already secured in the risen Lord.

Dr. C. N. Willborn, pastor of Covenant PCA in Oak Ridge, Tennessee, speaks about the life, ministry, and enduring theological legacy of John Lafayette Girardeau—a figure often hidden in the shadow of Thornwell and Dabney, yet towering in pastoral warmth, covenant theology, and confessional clarity. Girardeau emerges as a remarkably gifted scholar, a pastor deeply loved by both enslaved and free Black congregants, and a theologian who married doctrinal precision with heartfelt pastoral care. Through stories of his early intellectual formation, his ministry at Zion Presbyterian Church, his courageous stand against segregation in 1874, and his role in shaping debates on adoption, the will, worship, and evolution controversies, listeners gain a moving portrait of a man captivated by Christ and devoted to the communion of the saints.

This episode invites us to look beyond caricatures of Southern Presbyterianism and see a pastor who was shaped by his Huguenot and Scottish heritage, attentive to the spiritual well-being of the marginalized, and unwavering in his conviction that the church must be governed by Scripture and formed by a robust federal theology. Girardeau’s story not only expands our understanding of American Presbyterian history—it encourages believers today to pursue ministry marked by doctrinal fidelity, Christ-centered preaching, and sacrificial love.

In this conversation from Austin, Jim Cassidy, Lane Tipton, and Camden Bucey reflect on the abiding value of the Westminster Shorter Catechism as a tool for cultivating a God-centered, covenantally rich, and confessionally rooted Christian life. The discussion highlights Jim’s new book, Introducing the Faith: A Study of the Westminster Shorter Catechism, which serves as a written complement to his two free Reformed Academy courses through which he teaches the Shorter Catechism (Questions 1–38 and Questions 39–106). Together, the hosts trace their own histories with the Standards, demonstrating how catechesis shapes believers in the chief end of man—to glorify and enjoy God forever. They also explore how the catechism’s covenant theology anchors the church in biblical teaching, safeguarding the glory of God amid contemporary pressures.

The discussion turns to the weighty task of confessional subscription—its history, responsibilities, and the risks of revision. With pastoral clarity and historical attentiveness, the hosts encourage churches and teachers to handle their confessions with both gratitude and vigilance. The episode concludes with a look at the ongoing mission of Reformed Academy and the resources being developed to strengthen the church in catechesis and confessional fidelity.

In this installment of Vos Group, Camden Bucey and Lane Tipton explore pages 392–395 of Geerhardus Vos’s Biblical Theology and his rich, God-centered understanding of righteousness within the kingdom of God. They emphasize that true righteousness is never a human-centered moral construct but is rooted entirely in the character, will, and sovereign rule of the triune God. Vos contrasts biblical righteousness with pagan and modern distortions that treat ethics as merely horizontal or civic. Instead, righteousness is what agrees with, pleases, and exists for God—meaning believers live every moment coram Deo, before His face, in covenant fellowship.

The episode also unpacks how righteousness relates organically to the coming of God’s kingdom: it is concurrent with God’s reign, a gift worked by the Spirit, and graciously rewarded for Christ’s sake. Camden and Lane draw out the pastoral comfort that Christ—who possesses unlimited dominion—reigns not only from heaven but also within the hearts of His people. This kingdom reality transforms daily obedience into worship, participation in God’s redemptive purposes, and hopeful anticipation of our final inheritance in Him.
