Master the councils that made Christian doctrine

If you have spent any time reading theology or Church history seriously, you have almost certainly arrived at a moment of frustration — the moment when a creed, a council, or a technical term like hypostasis or homoousios appears without adequate explanation, and you realize that what lies behind it is a vast, contested, and extraordinarily consequential argument that no one has properly walked you through. That frustration is entirely reasonable. The ecumenical councils are foundational to Christian thought, referenced everywhere, and rarely taught with the rigor they deserve outside of graduate seminaries — and even there, not always well.

That gap is precisely what this course is designed to close. I have spent years working through the primary sources, the historical scholarship, and the theological debates that surround the seven great councils, and what I have come to believe is this: the councils only make sense when you hold the history and the theology together. Athanasius's defense of Nicene orthodoxy is not merely a doctrinal position — it is a life lived under exile and pressure, in a Church where emperors had very strong opinions about theology. Maximus the Confessor's insistence on two wills in Christ is not an abstraction — it is a conviction he defended at the cost of his hands and his tongue. When you see doctrine embedded in that kind of human reality, it stops being academic and becomes something you can genuinely grapple with.

I have also taken seriously the ecumenical dimension of this material. Students and clergy come to this course from Catholic, Orthodox, Anglican, and Protestant backgrounds, and they deserve a treatment that is honest about where the traditions agree, where they diverge, and why — without smuggling in a confessional verdict disguised as historical objectivity. My aim throughout is to give you the tools to think for yourself: to read a conciliar text, situate it in its context, understand what was actually at stake, and form a considered judgment.

What you will carry away from this course is not a list of councils and dates — it is a framework. A coherent, historically grounded understanding of how the Church came to confess what it confesses about the Trinity and the person of Christ, built on your own encounter with the primary sources. That framework will serve you whether you are a seminarian preparing for ordination, a lay person deepening your faith, a scholar working across traditions, or simply a serious reader who wants to understand one of the most consequential intellectual and spiritual dramas in human history.

I invite you to join me in taking these councils as seriously as the people who argued, prayed, and sometimes suffered over them did. The questions they debated are not solved puzzles to be filed away — they are living questions, and this course will help you inhabit them.
