Know the Holy Spirit as Scripture, creed, and history reveal Him
A full-curriculum pneumatology — from the Spirit hovering over creation to His eschatological work at the end of the age — built on careful exegesis, creedal theology, and the great doctors of the Church. This is the doctrinal depth most believers never receive.

"I want you to leave this school able to say not just that you believe in the Holy Spirit, but that you know — from Scripture, from creed, from the great doctors of the Church — exactly what it is you believe, and why it changes everything."

What you'll learn
What you'll be able to do
- Trace the Holy Spirit's presence and activity across both the Old and New Testaments, from creation and inspiration through Pentecost and the early Church
- Articulate the biblical and creedal basis for the Holy Spirit as the Third Person of the Trinity, drawing on the Nicene and Constantinopolitan Creeds and the Cappadocian Fathers
- Analyze the Spirit's role in the life and ministry of Jesus — incarnation, baptism, miracles, resurrection, and ascension — and explain its implications for Christology and soteriology
- Explain the major theological works of the Spirit — regeneration, indwelling, sanctification, illumination, assurance, and intercession — and apply them to the Christian life and spiritual formation
- Evaluate differing Christian traditions on baptism in the Spirit, continuationism vs. cessationism, prophecy, healing, and tongues with biblical precision and charitable theological judgment
- Situate pneumatology within the broader framework of systematic theology, demonstrating how a robust doctrine of the Spirit deepens discipleship, unifies the Church, and draws believers into communion with the triune God

Who it's for
Is this you?
Seminary students
Building a systematic theology from the ground up, they need pneumatology that integrates exegesis, historical theology, and creedal formation — not a survey.
Pastors & preachers
They preach on the Spirit regularly but want the doctrinal scaffolding — from Cappadocian theology to the filioque to Romans 8 — that makes their preaching theologically coherent.
Lay theologians
Serious self-taught believers who have outgrown popular-level treatments and are ready to engage primary sources, creeds, and the full arc of pneumatology in Scripture.
Charismatic & Reformed dialogue seekers
Sitting at the intersection of traditions, they want a fair-handed, exegetically grounded treatment of baptism in the Spirit, continuationism, and spiritual gifts — not a polemic.
Spiritual formation students
Drawn to deeper prayer, sanctification, and life in the Trinity, they need a doctrinal foundation that explains why the Spirit's works — regeneration, assurance, intercession — actually matter for formation.
Church leaders & elders
Guiding congregations through questions about the Spirit's gifts, unity, and mission, they need the historical and systematic grounding to lead with wisdom and confidence.

Theoria
If you are reading this, I suspect you already sense the problem. You have confessed the Holy Spirit in the Creed for years. You have heard Him invoked in sermons, praised in worship, and appealed to in theological arguments from nearly every direction. And yet — if you are honest — you have never worked through a full, grounded, historically-anchored account of who He is, what Scripture actually says about His work, and how the Church came to confess what it confesses about the Third Person of the Trinity. That gap is not a failure of faith. It is a gap in formation, and it is precisely what this school exists to close.
I designed Spirit & Doctrine because I kept meeting serious Christians — pastors, seminary students, lay leaders, committed laypeople — who could articulate the gospel with precision, defend the authority of Scripture, and explain the atonement in some depth, but who had never traced the Spirit's presence across the whole of Scripture, never read Basil of Caesarea on the Spirit's deity, and never worked through the exegetical questions that actually divide charismatics and cessationists. The doctrine of the Spirit was either crowded out by other topics or reduced to a battlefield. Neither outcome serves the Church.
What you will find in this school is theology that begins with the text. Every major doctrinal claim is anchored in careful exegesis — of Genesis 1, of the Servant Songs, of the Upper Room Discourse, of Romans 8 — before it is synthesized into a systematic account. Technical terms are not assumed; they are introduced, defined, and illustrated before being used. Primary sources are quoted directly, because there is no substitute for reading what Basil, Augustine, and Calvin actually wrote. I want you to engage the tradition, not merely hear about it.
I also want to be clear about what this school will and will not do. It will give you the tools to hold a well-reasoned position on the disputed questions — baptism in the Spirit, the continuation or cessation of the sign gifts, the nature of prophecy today — and to understand charitably the positions you do not hold. It will not tell you that the debate is simple, or that one tradition has nothing to learn from another. Theological honesty requires us to sit with complexity before we reach for resolution.
The goal, finally, is not a theology degree. It is a life more deeply rooted in the triune God — a discipleship that knows why the Spirit regenerates, sanctifies, assures, intercedes, and draws every believer toward the Father through the Son. Come ready to read carefully, think precisely, and be formed. There is no better subject for it than the One whom Jesus called the Spirit of truth.
