Theoria: The Protestant Reformation

"The Reformation deserves to be understood on its own terms — its theology taken seriously, its sources read carefully, and its complexity honored rather than flattened."

Theoria

What you'll learn

What you'll be able to do

  • Trace the religious, political, and cultural conditions of late medieval Europe that made the Reformation possible, including the role of humanism, the printing press, and pre-Reformation reformers like Wycliffe and Hus.
  • Explain the core theological convictions of the Reformation — sola Scriptura, sola fide, sola gratia, solus Christus, and soli Deo gloria — and articulate what was genuinely at stake in each debate.
  • Compare the distinct contributions and theological differences of major Reformation figures: Luther, Zwingli, Calvin, Cranmer, Knox, and Menno Simons, across Lutheran, Reformed, Anglican, and Anabaptist traditions.
  • Analyze the Catholic Counter-Reformation, the Council of Trent, and the confessional conflicts that reshaped the religious map of Europe in the sixteenth and seventeenth centuries.
  • Interpret key Reformation primary sources — theses, confessions, catechisms, and treatises — within their proper historical and theological contexts, evaluating arguments with discernment rather than anachronism.
  • Assess the Reformation's long-term influence on Bible translation, literacy, education, political thought, denominational identity, and the shape of global Christianity today.

Theoria

Theoria

If you have spent any time studying the Reformation, you have likely felt the frustration of resources that give you the outline but not the substance — Luther posts his theses, Calvin writes his Institutes, the church fractures, and somehow we arrive at the denominational landscape of today. The story moves quickly, the theology stays thin, and you are left with the sense that something essential has been skipped over.\n\nThat frustration is what this school was built to address. The Reformation is, at its core, a theological event — a set of urgent, costly convictions about how sinners stand before God, where authoritative teaching comes from, and what the church is for. Those convictions drove real people to risk their careers, their freedom, and their lives. To understand the history without understanding the theology is to watch the action without hearing the dialogue.\n\nWhat you will find here is a curriculum that moves slowly enough to actually read the sources, carefully enough to hold the theological distinctions clearly, and honestly enough to acknowledge that the people involved — reformers and defenders of Rome alike — were not simple heroes and villains but serious men and women grappling with serious questions. Luther at Worms, Zwingli at Marburg, the Anabaptists before the magistrates, the fathers at Trent: each moment is examined on its own terms, with the historical context that makes sense of it and the theological stakes that made it matter.\n\nI want you to leave this school able to read a Reformation confession or catechism and know what it is doing — what question it is answering, what opponent it has in view, what it is willing to stake a claim on. I want you to understand why Luther and Zwingli, though they agreed on so much, could not reach agreement at Marburg, and why that failure had consequences that ripple into the present. I want you to see the Counter-Reformation not as a mere reaction but as a genuine effort at self-examination within a tradition that also took theology seriously.\n\nWhether you are a pastor working through the confessional heritage of your tradition, a student building the historical foundation your seminary courses assumed you had, or simply a historically serious Christian who wants more than a Wikipedia-level account, this school was made for the kind of careful, sustained attention you are ready to bring. Come prepared to read, to think, and to have your understanding of one of history's most consequential movements genuinely deepened.
