The fastest way to misunderstand Christianity is to treat the Trinity like a math puzzle or a dusty debate from the fourth century. We pick up Westminster Confession of Faith chapter two and follow the doctrine of the Trinity where it actually comes from: the Bible’s own speech about the Father, the Son, and the Holy Spirit, with the Gospel of John front and center. Drew Brackbill helps us connect Scripture, church history, and the real-world stakes of orthodox Christian doctrine.

From the apostle John’s insistence on the Word’s full divinity to the Anti-Nicene Fathers like Ignatius, we trace how Trinitarian theology shows up early and clearly before any ecumenical council meets. Then we explain why the word “Trinity” appears later than the belief, how terms like “one substance” (consubstantiality) help the church speak precisely, and why that precision is meant to protect biblical faith rather than replace it.

We also walk through the major Trinitarian controversies that shaped the early church: modalism (Sabelianism) and Arianism, why they sounded persuasive, and why the Council of Nicaea and Athanasius mattered. Finally, we bring it into the present with modern examples and the ongoing question of creeds, confessions, and “no creed but the Bible.” If you care about the atonement, salvation, and faithful worship, this conversation lands close to home.

Pastor Cisco Victa sits down with Drew Brackbill to discuss Chapter 2 of the Westminster Confession of Faith, Of God and of the Holy Trinity. Together they explore what the Confession teaches about the nature and attributes of the one true and living God and how Scripture reveals that this one God exists eternally as Father, Son, and Holy Spirit.

In this conversation they begin to look at the historical development of the doctrine of the Trinity and the early church controversies that forced Christians to clarify their theology. From the writings of the early church fathers to the Council of Nicaea in 325 AD, they discuss how the church responded to errors such as modalism and Arianism and defended the biblical teaching that Christ is begotten, not made, and of the same essence as the Father.

Join us as we consider why the doctrine of the Trinity stands at the center of the Christian faith and why it continues to matter for the church today.

In this episode of Catechizing Conversations, Cisco Victa and Drew Brackbill continue their study of the Westminster Standards by focusing on Westminster Shorter Catechism Q.2 and Chapter 1 of the Westminster Confession of Faith.

They explore why Scripture is the only rule to direct us how to glorify and enjoy God, clarifying the Reformed doctrine of sola Scriptura. The conversation addresses the role of church tradition, contrasts Protestant and Roman Catholic views of authority and canon, and explains how the Holy Spirit bears witness to Scripture’s divine authority.

They also discuss the self-authenticating nature of Scripture, the perspicuity (clarity) of the Bible in matters necessary for salvation, and the responsibility of every believer to test teaching by God’s Word—like the Bereans in Acts 17. The episode concludes with practical encouragement to approach Scripture prayerfully, trusting the Spirit to illuminate the gospel through the written Word.
