Dr. Guy Waters is the Professor of New Testament at the Reformed Theological Seminary, Jackson, Mississippi and a teaching elder in the Mississippi presbytery of the Presbyterian Church in America. Today, he joins us to speak about his book, One, Holy, Catholic, and Apostolic Church (Lexham Academic), in which he sets out a full-scale Reformed doctrine of the church. The title echoes the four classical “marks” confessed in the Niceno-Constantinopolitan Creed. This study is an extended exploration of how Scripture, read through a Reformed lens, fills out each of those creedal descriptors and binds them together into a single, coherent doctrine of the church.

Dr. Waters organizes the book in three movements:

The conclusion distills the argument into seven theses that function as a theological checksum. Throughout, Waters interlaces biblical exegesis, historical theology and confessional sources (especially the Westminster Standards). The result is both an academic survey and a pastoral manifesto aimed at equipping the church for faithful witness today.

The conversation explores the essential identity and mission of the church, the continuity between the Old and New Testaments, and what is distinctly new through Christ’s redemptive work. Waters outlines the seven theses of his book, offering clarity on ecclesiology for today’s church, particularly in light of confusion over polity, worship, and the church’s relation to the state.

This episode is an invitation to recover a robust, Reformed understanding of the church’s nature and calling, rooted in Scripture and developed in the tradition of historic confessions.

In this installment of the Vos Group, Camden Bucey and Lane Tipton turn to pages 378–381 of Geerhardus Vos’s Biblical Theology: Old and New Testaments, focusing on Jesus’ teaching and the eschatology of the kingdom. They explore the vital biblical distinction between the “already” and “not yet” aspects of the kingdom of God, examining how this two-age structure stands in contrast to various eschatological systems, including premillennialism, postmillennialism, and what Vos labels “ultra-eschatology.”

Tipton and Bucey analyze Vos’s critique of these systems, highlighting the theological implications of denying either the inaugurated or consummated dimensions of the kingdom. They also discuss the resurrection, the second coming of Christ, and the theological coherence of amillennialism within the Reformed tradition. In the course of the discussion, they reflect on the life and teaching of Dr. Robert B. Strimple, affirming his Christ-centered theological pedagogy and lasting influence.

Listeners will find this episode a robust and thought-provoking engagement with biblical theology, eschatology, and Reformed orthodoxy.

In this episode of Christ the Center, Camden Bucey is joined once again by Lane Tipton and Carlton Wynne for a substantive follow-up to their earlier discussion of Keith Mathison’s Toward a Reformed Apologetic: A Critique of the Thought of Cornelius Van Til. In the months since their first review, Dr. Mathison published a blog response, prompting deeper analysis and clarification.

Together, Drs. Bucey, Tipton and Wynne explore key critiques Mathison levels against Van Til, especially the claims of epistemological idealism and the so-called “omniscience requirement” for true knowledge. The panel addresses these concerns with thoughtful care, highlighting Van Til’s emphasis on covenantal epistemology, the distinction between psychological and ethical knowledge, and the non-neutrality of unbelieving thought.

The episode also tackles Mathison’s treatment of common grace and the antithesis—core concepts in Van Til’s apologetic system. Does Van Til teach that unbelievers attain true knowledge by way of common grace? What is the actual function of common grace in a fallen world? And how does Van Til preserve the absolute ethical antithesis between belief and unbelief without denying shared external reality or meaningful engagement?

This is a clarifying and edifying conversation for anyone interested in Reformed theology, presuppositional apologetics, or the legacy of Cornelius Van Til.

In this episode we welcome Dr. Michael Morales—professor of biblical studies at Greenville Presbyterian Theological Seminary—for a conversation exploring the profound theological vision of the book of Numbers. Drawing from his newly released two-volume commentary in the Apollos Old Testament Commentary series, Dr. Morales unveils Numbers as more than ancient census lists and wilderness wanderings. Instead, it emerges as a richly textured narrative of covenant community, leadership, and the Lord’s presence among his people.

Listeners will discover how the structure of Israel’s camp reflects Edenic hope and eschatological promise, how Numbers addresses the roles of prophet, priest, and king, and why the priestly blessing and Balaam’s oracles form theological bookends to this journey toward the Promised Land. Dr. Morales also shares personal reflections from his ten-year labor on the commentary, emphasizing the pastoral power and redemptive-historical depth of this often-overlooked book.

Whether you’re a pastor, seminary student, or serious Bible reader, this conversation will reinvigorate your love for the Pentateuch and deepen your grasp of how all Scripture points us to Christ.

Leonardo De Chirico and Mark Gilbert join the program to discuss the enduring significance of the Nicene Creed as it marks its 1700th anniversary. Drawing from their recent edited volume, The Nicene Creed: The Nature of Christian Unity and the Meaning of Gospel Words (Matthias Media), the guests explore how shared creedal language can mask deep theological differences, particularly between evangelical and Roman Catholic traditions.

Leonardo De Chirico is a pastor of a Reformed evangelical church in Rome, a scholar of Roman Catholic theology, and a leader in the Reformanda Initiative, which seeks to equip evangelical engagement with Roman Catholicism. Mark Gilbert serves as a chaplain in Sydney, Australia, and leads the ministry Certainty for Eternity, which focuses on evangelism among those from Roman Catholic backgrounds. Both men bring rich theological and pastoral insight to bear on the question of unity in Christ.

The conversation traces the origins of the creed, its Trinitarian framework, and the implications of confessing shared historical truths while diverging in doctrinal substance—especially concerning Christology, the church, and salvation. Leonardo and Mark also share personal insights from their ministries engaging Roman Catholics, underscoring the need for unity rooted in biblical truth rather than institutional alignment or superficial consensus.

This episode invites thoughtful reflection on what true Christian unity looks like in light of Scripture, and how the creeds function as faithful, yet insufficient, summaries apart from a Reformed understanding of the gospel.

In this episode Camden Bucey welcomes Dr. Jonathan Master, president of Greenville Presbyterian Theological Seminary and host of the new podcast Dead Presbyterians Society. Together, they reflect on the theology and practice of public prayer, drawing upon the insights of 19th-century Presbyterian theologian Samuel Miller and his underappreciated classic, Thoughts on Public Prayer.

The conversation addresses the enduring importance of prayer in the public ministry of the church. Dr. Master discusses why pastors must be both God’s mouthpiece to the people through preaching and the people’s mouthpiece to God through prayer. The episode includes a full episode of Dead Presbyterian Society, in which Master offers a deep and moving treatment of Miller’s work—highlighting frequent faults in public prayer, the characteristics of excellent prayer, and the secret devotional habits that sustain it.

Whether you’re a pastor, elder, seminarian, or thoughtful church member, this episode is a call to recover the dignity, order, and spiritual power of public prayer in Reformed worship.

What did Jesus mean when he spoke of “the kingdom of God” or “the kingdom of heaven?” In this episode, we turn to Geerhardus Vos’s Biblical Theology, pages 375–378, where he unpacks the theological and biblical contours of the kingdom in the Gospels. Lane Tipton and Camden Bucey explore the critical distinction Vos draws between the abstract and concrete senses of the kingdom, the Old Testament background, and how the kingdom becomes incarnate in the person and work of Christ.

Together, we discuss

This episode offers rich theological insight and practical clarity for pastors, students, and anyone seeking to understand the kingdom according to Scripture and sound Reformed theology.

In this episode of Christ the Center, Camden Bucey and Carlton Wynne are joined by Rev. Stephen Spinnenweber, author of Loving the Law: The Law of God in the Life of the Believer (Christian Focus), to explore the enduring significance of God’s moral law in the Christian life. They discuss the book’s development, its theological foundations, and its practical applications for pastors, congregants, and Christian parents.

The conversation clarifies the Reformed understanding of the threefold use of the law and addresses common misconceptions surrounding legalism and antinomianism. Stephen offers a pastoral and theologically rich vision for delighting in the law as a gracious guide for believers—one rooted in God’s character and purpose for humanity. The trio also touches on civil use of the law, the Sabbath, and the broader cultural and political implications of God’s moral order.

This episode is a refreshing call to recover a joyful obedience to God’s commandments—not as a means of earning salvation, but as the grateful response of those saved by grace and empowered by the Spirit.

In this rich theological conversation, Camden Bucey welcomes Dr. Harrison Perkins—pastor, scholar, and author—to discuss his two latest books: Righteous by Design: Covenantal Merit and Adam’s Original Integrity (Christian Focus) and Created for Communion with God: The Promise of Genesis 1–2 (Lexham Press). Together, they explore foundational Reformed doctrines related to covenant theology, the image of God, and the eschatological purpose embedded in creation itself.

Dr. Perkins offers historical and systematic clarity on the oft-debated notion of merit in the covenant of works, contrasting Reformed and Roman Catholic anthropologies. He also unpacks the pastoral dimensions of humanity’s creation for communion with God, showing how Genesis 1–2 serves not merely as a record of origins, but as a divine love letter calling God’s people into eternal fellowship.

Whether you’re a pastor, scholar, or thoughtful layperson, this episode provides deep insight into how theology—rooted in Scripture and the Reformed tradition—shapes our understanding of God, humanity, and the gospel of Jesus Christ.

In this episode of Christ the Center, Camden Bucey welcomes Dr. J. Brandon Burks, pastor of Christ Reformed Church (URCNA) in Florence, Kentucky, to discuss his recent article published in The Confessional Presbyterian Journal (Vol. 20, 2024): “The Puritans and the Salem Witch Trials: Living According to God’s Revealed Will.”

Together, they explore the theological context of the infamous Salem witch trials of 1692, uncovering how speculative theology and reliance on so-called “spectral evidence” reflected a deeper deviation from Scripture’s clarity and sufficiency. Dr. Burks outlines the influence of figures such as William Perkins, Cotton Mather, and Richard Baxter, while also shedding light on how the distinction between God’s secret and revealed will was tragically misunderstood.

The conversation goes beyond history, offering timely insights into contemporary fascination with mysticism, the spiritual dangers of neglecting the ordinary means of grace, and the need for biblically grounded theology in facing spiritual warfare today. They conclude by considering the value of a redemptive-historical and confessional framework in pastoral ministry and theological education.
