The Reformation: Overview

Historical Theology

The Church in This Era

The sixteenth century opened upon a church outwardly magnificent and inwardly troubled. The Latin West was one visible communion under the bishop of Rome, its calendar full of feast and fast, its cathedrals rising toward heaven, its scholars heirs to a thousand years of accumulated learning. Yet beneath the splendor ran a deep ache. Conscientious souls could not find peace. The treasury of merit, the round of penances, the purchasing of indulgences, the long ladder of works by which a sinner was to climb toward an uncertain acceptance — these had bred not assurance but dread. The late medieval system had not failed to be religious; it had failed to comfort.

Into this ache the gospel broke again, not as novelty but as recovery. The Reformation was, at its heart, the rediscovery that a sinner is justified before God by faith alone, on the ground of Christ alone, received by grace alone, as Scripture alone teaches, to the glory of God alone. What looked to Rome like rebellion the Reformers understood as homecoming — the church returning to her own foundation.

“For in it the righteousness of God is revealed from faith for faith, as it is written, ‘The righteous shall live by faith.’” (Rom. 1:17)

Where We Are in the Story

We stand at the great hinge between the medieval church and the modern. Behind us lie the forerunners: Wycliffe and Hus, the devotio moderna, the Christian humanists with their cry ad fontes — back to the sources. Erasmus had given Europe a printed Greek New Testament in 1516, and the printing press now carried words across borders faster than any council could chase them. Before us lie the confessional churches, the post-Reformation scholastics, and the Westminster Assembly. This era is the watershed from which the streams of Lutheran, Reformed, Anabaptist, and Anglican Christianity all flow.

Key Figures

Martin Luther (1483–1546), the Augustinian friar whose tortured conscience and tower discovery lit the fuse, and whose courage at Worms set the tone for an age.

Huldrych Zwingli (1484–1531), the Zurich reformer who came to the gospel by way of humanist study of Scripture and pressed reform by the plain Word.

John Calvin (1509–1564), the second-generation Frenchman in Geneva whose Institutes gave the Reformed faith its enduring order and depth.

Thomas Cranmer (1489–1556), Archbishop of Canterbury, author of the Book of Common Prayer, and martyr.

Menno Simons (1496–1561) and the Swiss Brethren, who carried reform further than the magisterial Reformers would go.

Ignatius of Loyola (1491–1556), founder of the Jesuits and emblem of Rome’s vigorous renewal.

Key Controversies and Developments

The age turned on a handful of questions. How is a sinner justified? — by imputed righteousness received through faith, or by grace infused and cooperated with unto a final verdict? What is the supreme authority? — Scripture alone, or Scripture-and-tradition interpreted by the magisterium? What happens at the Lord’s Table? — and here even the Reformers divided, Luther holding a bodily presence, Zwingli a memorial, with Calvin later seeking a true spiritual feeding. Who belongs to the visible church? — the baptized infant of the covenant household, or only the professing believer? What is the relation of church and magistrate? The Reformation did not produce a single answer to all of these; it produced families of answers, and the boundaries between those families are still with us.

Councils, Creeds, and Confessions

The era was extraordinarily fertile in confession. Luther’s catechisms (1529) taught a generation; the Augsburg Confession (1530) defined Lutheran identity. In the Reformed lands came the Tetrapolitan and First Helvetic Confessions, and later the towering Heidelberg Catechism (1563) and Second Helvetic Confession (1566). The radicals set down the Schleitheim Confession (1527). England produced the Book of Common Prayer (1549, 1552) and the Thirty-Nine Articles (1563/1571). And Rome answered all of these at the Council of Trent (1545–1563), which fixed Catholic doctrine for four centuries and pronounced its anathemas against the evangelical gospel.

What Was Settled — and What Was Left

Within the evangelical churches, the material principle (justification by faith) and the formal principle (the supremacy of Scripture) were settled with a clarity that has never been wholly lost. What was left unsettled was the visible unity of Protestantism. Marburg (1529) failed to reconcile Wittenberg and Zurich over the Supper. The baptismal question divided magisterial from radical. The English settlement left a half-reformed church that would breed the Puritan struggle of the next century (see 05_04). The Reformation healed the church’s understanding of grace and fractured her outward fellowship — a sober inheritance.

A Reformed Assessment

We receive this era with deepest gratitude, for in it the lamp of the gospel was set again upon its stand. Yet semper reformanda forbids idolatry even of the Reformers. They were men, and they erred — in the harshness that crept into Luther’s later polemics, in the entanglement of gospel and sword at Münster and elsewhere, in the persecutions that stained every party including our own. We honor Calvin’s Geneva without canonizing it. The wheat is the recovered gospel of free grace; the chaff is the residue of an age that still confused the church’s spiritual weapons with the magistrate’s temporal ones. We test even our fathers by Scripture (WCF 1.10), and finding the gold, we give thanks.

Lessons for the Church Today

The Reformation teaches the church to keep the main thing the main thing: a guilty conscience needs a righteousness it cannot manufacture. It teaches that doctrine is pastoral — Luther’s whole upheaval began as the cure of one terrified soul. It warns that recovered truth can harden into new partisanship, and that zeal for the Word must be wedded to charity toward the brother who reads it differently. And it summons every generation to the same posture: not novelty, but recovery; not the church’s voice over Scripture, but Scripture over the church.
