History — Module I
The Protestant Reformation
The religious, intellectual and political movement that divided Western Christendom. From Wittenberg (1517) to the Peace of Westphalia (1648).
The Causes of the Reformation
The Reformation is a multicausal phenomenon -- neither reducible to Luther's doctrinal revolt alone nor to a mere institutional crisis. Five orders of causality interweave.
1. Theological Causes
At the heart of the Reformation lies a soteriological question: how is humanity justified before God? The late medieval Church had developed, under the influence of nominalism (Gabriel Biel), the doctrine of facere quod in se est: doing "what is within oneself" to merit grace. Luther, trained by Biel at Erfurt, suffered deeply under this soteriology. His discovery of Rom 1:17 (~1515) constitutes the founding rupture: the iustitia Dei is not punitive but donative.
2. Institutional Causes
The Renaissance papacy (Alexander VI Borgia, Julius II "the warrior pope," Leo X) reached an unprecedented level of worldliness. The sale of offices (simony), accumulation of benefices, episcopal absenteeism, and ignorance of rural clergy -- all documented grievances. The sale of indulgences by Tetzel (1517) to finance St. Peter's in Rome was the spark of a powder keg building for decades.
3. Cultural Causes -- Humanism
Erasmus of Rotterdam (Praise of Folly, 1511) prepares the ground through his critique of abuses and his return to the sources (ad fontes). Humanist philology -- Lorenzo Valla demonstrating the falsity of the Donation of Constantine -- undermines medieval traditions. Erasmus edits the Greek NT in 1516: Luther and his contemporaries read Paul in his original language.
4. Technical Causes -- The Printing Press (~1450)
Without Gutenberg, no Reformation in this form. The 95 Theses circulated within weeks. In two years, Luther published more works than any other author since the invention of printing. The press democratized the biblical text and bypassed the ecclesiastical hierarchy.
5. Political Causes -- The German Princes
The structure of the Holy Roman Empire -- with its semi-sovereign princes -- allowed the Reformation to take root before Charles V could react. The Edict of Worms (1521) condemned Luther, but Elector Frederick III of Saxony protected him at the Wartburg. The Peace of Augsburg (1555) gave constitutional recognition to Lutheranism.
The Indulgence Affair -- Concrete Trigger
Johann Tetzel sold indulgences with the popular formula (apocryphal): "As soon as the coin rings in the coffer, the soul springs from purgatory." (Sobald das Geld im Kasten klingt, die Seele aus dem Fegefeuer springt.) Luther, pastor of Wittenberg, saw his parishioners buying indulgences instead of confessing. He drew up the 95 Theses -- originally an internal academic debate, without anticipating the chain reaction triggered by the printing press.
The Four Great Reformers
Martin Luther
1483-1546 / Wittenberg
LutheranAugustinian monk, doctor of theology. His 95 Theses (1517) open the Reformation. Translator of the German Bible (1522/1534). Maintained real corporeal presence in the Supper against Zwingli.
« Here I stand, I can do no other. »
Ulrich Zwingli
1484-1531 / Zurich
Reformed (Zurich)Humanist, priest of the Grossmuenster. Reformed Zurich from 1519, independently of Luther. Symbolic presence in the Supper. Died in battle at Kappel (1531).
« The bread is bread, the wine is wine. »
John Calvin
1509-1564 / Geneva
Reformed (Geneva)Humanist jurist. Institutes (1536). Organized Geneva with the Ecclesiastical Ordinances (1541): pastors, doctors, elders, deacons. His international correspondence network made him the most influential Reformer long-term.
« Our heart is a perpetual factory of idols. »
Martin Bucer
1491-1551 / Strasbourg
Reformed (Strasbourg)Converted Dominican. Great mediator between Luther and Zwingli. Influenced Calvin during his Strasbourg stay (1538-1541). Fled to England under Edward VI. His irenicism prefigures ecumenism.
« Let us first agree on the essentials. »
Chronology of the Reformation (1517-1648)
Beyond the Reformation (1648–2025): Legacy and Posterity
The Peace of Westphalia ended the wars of religion but did not close the dynamic of reformation. Over the four following centuries, Christian theology — Protestant, Catholic, and Orthodox — has been profoundly reconfigured. This section presents the main phases of this legacy and the major theologians of the three traditions.
Protestant Orthodoxy and Confessional Theology (1580–1700)
A generation that systematized and codified the heritage of the Reformers in great dogmatic summae inspired by the scholastic method. On the Lutheran side, Martin Chemnitz (Loci Theologici, 1591) and Johann Gerhard (Loci Theologici, 9 vols., 1610–1622). On the Reformed side, Theodore Beza, Amandus Polanus (Syntagma Theologiae Christianae, 1609), Johannes Wollebius, Gisbertus Voetius (Utrecht), Johannes Cocceius (covenant theology), Francis Turretin (Institutio Theologiae Elencticae, 3 vols., 1679–1685, Academy of Geneva). National Synod of Dordrecht (1618–1619) — canons fixing Reformed doctrine against Arminianism. Westminster Assembly (1643–1649) — Westminster Confession, Larger and Shorter Catechisms, normative for Anglo-Saxon Presbyterianism.
Pietism and Revivals (1675–1830)
A reaction to orthodox intellectualism: return to personal piety, conversion, sanctification. Philipp Jakob Spener, Pia Desideria (1675) — the manifesto. August Hermann Francke at Halle. Nikolaus Ludwig von Zinzendorf and the Herrnhut community (Moravians, 1722). On the English side, John Wesley and Methodism (1738 — Aldersgate conversion). American revivals: Jonathan Edwards and the Great Awakening (1734–1742). Geneva Revival around Robert Haldane (1816–1817), then Louis Gaussen, Merle d'Aubigné, César Malan. Revival of Lyon, of Northern France.
Enlightenment, Liberal Theology, and Historicism (1750–1914)
Application of critical reason to theology. Hermann Samuel Reimarus (Fragments, 1774–1778) inaugurates the historical criticism of the Jesus of the Gospels. Friedrich Schleiermacher (1768–1834), "father of modern theology," Reden über die Religion (1799), Der christliche Glaube (1821–1822) — religion as the "feeling of absolute dependence." Albrecht Ritschl, Adolf von Harnack (Das Wesen des Christentums, 1900) — "essence of Christianity" reduced to the ethics of the Kingdom. School of the history of religions (Hermann Gunkel, Wilhelm Bousset). Ernst Troeltsch (Die Absolutheit des Christentums, 1902; Die Soziallehren, 1912). On the Catholic side: Loisy and the modernist crisis (Pascendi, 1907). Neo-Thomist revival under Leo XIII (Aeterni Patris, 1879).
Dialectical Theology and Neo-Orthodoxy (1918–1968)
A reaction to liberalism after the First World War. Karl Barth, Der Römerbrief (1919, 2nd ed. 1922), then Kirchliche Dogmatik (13 vols., 1932–1967) — revelation as "Wholly Other," primacy of the Word of God. Emil Brunner, Friedrich Gogarten, Eduard Thurneysen. Rudolf Bultmann and demythologization (1941). Dietrich Bonhoeffer, martyr of Nazism, Nachfolge (1937), Ethik (posthumous 1949), Widerstand und Ergebung (posthumous 1951). Paul Tillich, Systematic Theology (3 vols., 1951–1963) — correlation of theology and culture. Oscar Cullmann at Basel/Paris — theology of salvation history.
Vatican II, Ecumenism, and Contemporary Theologies (1965–2025)
Second Vatican Council (1962–1965): Catholic aggiornamento, recognition of ecumenism and dialogue with other religions. World Council of Churches (WCC, founded Amsterdam 1948). Major documents: Baptism, Eucharist, and Ministry (Lima, 1982); Joint Declaration on the Doctrine of Justification (Augsburg, 1999) between the Roman Catholic Church and the Lutheran World Federation. Proliferation of contextual theologies: liberation (Gutiérrez 1971, Boff, Sobrino), feminist (Ruether, Schüssler Fiorenza), Black (Cone), postcolonial (Sugirtharajah), ecological (McFague, late Moltmann).

Luther at the Diet of Worms -- Sola Scriptura in Action
Acts of the Diet of Worms, 18 April 1521 / WA 7, 838 / LW 32, 112
🔍 Analysis
This text formulates Sola Scriptura in a crisis context. Luther doubly refuses: absolute pontifical authority AND infallible conciliar authority. What remains is only Scripture and "evident reason." Conscience is not sovereign -- it is bound to the Word. A formula that foreshadows the Enlightenment while remaining within a scriptural framework.
📚 Glossary
Indulgence
indulgentia
Total or partial remission of the temporal penalty for sin. The sale of indulgences for the deceased (purgatory) triggered the 1517 controversy.
DH 1467-1472Cuius regio eius religio
Peace of Augsburg, 1555
As the ruler, so the religion -- the prince determines the confession of his territory. Calvinism excluded until 1648.
Peace of Augsburg, §15Marburg Colloquy
1529
Attempted reconciliation Luther-Zwingli. Failed on the 15th article (Supper) -- founding rupture between Lutherans and Reformed.
October 1529Counter-Reformation
Contreformatio
Catholic reforms in response to the Reformation: Trent (1545-1563), Jesuits (1540), Inquisition (1542), Index (1559).
16th-17th c.Peasants' War
Bauernkrieg, 1524-1525
Social revolt using Luther's Reforming arguments. Luther violently condemned it, supported repression. Reveals the social conservatism of the magisterial Reformation.

Primary Sources
Reference Monographs
Supper
When and where did Luther post his 95 Theses?
↩
✓
October 31, 1517 at Wittenberg. Luther sent them to Bishop Albert of Mainz. According to tradition, he posted them on the door of the Castle Church (All Saints). The printing press circulated them rapidly throughout Germany and Europe. Luther initially expected an internal academic debate.
Peace
On what point did Luther and Zwingli break at Marburg?
↩
✓
The 15th article: the Lord's Supper. Luther: real corporeal presence in, with and under the bread and wine (Hoc est corpus meum = this IS my body). Zwingli: symbolic presence (est = significat). The Colloquy (1529) failed on this single point. Permanent rupture between Lutherans and Reformed.
Politics
What does cuius regio eius religio mean?
↩
✓
Peace of Augsburg (1555): 'as the ruler, so the religion.' The prince determines the confession of his territory (Lutheran or Catholic). Subjects who disagree must emigrate (ius emigrandi). Calvinism excluded until the Peace of Westphalia (1648). Principle that creates territorial confessionalization.
Irenicism
Which prince protected Luther after Worms?
↩
✓
Elector Frederick III of Saxony ('the Wise'), 1463-1525. He organized Luther's kidnapping to the Wartburg (1521) where Luther translated the NT into German (September Bible, 1522). Frederick never openly converted to Lutheranism, but protected Luther against Charles V.
Trent
Why is Bucer a key figure?
↩
✓
Mediator (concord attempts Luther-Zwingli: Wittenberg Concord, 1536). Influenced Calvin during Strasbourg (1538-1541) -- Calvin learned pastoral theology and liturgy. Irenicism prefigured ecumenism. Died in Cambridge (1551) under Edward VI. His book De Regno Christi inspired the English Reformation.
Death
What did Trent (1545-1563) reform in response to the Reformation?
↩
✓
Council of Trent: Catholic doctrinal response. Defined: 7 sacraments, transubstantiation, Tradition = co-normative with Scripture, justification (transformative, not forensic), Latin Vulgate as authentic. Reformed: seminary formation of the clergy, prohibited plurality of benefices, liturgical standardization (Tridentine Mass).
Language
How did Ulrich Zwingli die?
↩
✓
Battle of Kappel (October 11, 1531): Zurich Catholics against the Catholic cantons. Zwingli died in battle as a military chaplain. He was captured, executed, quartered, and burned. His death ended the first Reformed phase and opened the way for Bullinger at Zurich.
Lightning
What is the linguistic importance of Luther's Bible?
↩
✓
Luther's translation (NT 1522, complete 1534) forged standard German (Hochdeutsch). Luther used the Saxon chancellery language to be understood by all. He studied peasant dialects to find natural idioms. The Bible became the foundation of German literary culture. Similar influence: Tyndale for English (1525).
Calvin
What was the St. Bartholomew's Day Massacre (1572)?
↩
✓
Massacre of French Protestants (Huguenots) in Paris on the night of August 23-24, 1572, ordered by Charles IX under Catherine de Medici's influence. 3,000-5,000 deaths in Paris, 10,000-30,000 throughout France. Triggered by the assassination of Admiral Gaspard de Coligny. Decisive episode in the Wars of Religion (1562-1598).
The Reformation cannot be reduced to a single cause. Five interconnected factors: (1) Theological: Luther's soteriological crisis (how is humanity justified?) and his discovery of the donative justice of God (Rom 1:17). (2) Institutional: scandals of the Renaissance papacy, simony, sale of indulgences. (3) Cultural: humanist philology (Erasmus, Valla), return to sources, critical reading of Scripture. (4) Technical: the printing press (Gutenberg, ~1450) -- without it, the 95 Theses would not have spread beyond Wittenberg. (5) Political: the structure of the Holy Roman Empire and the support of German princes. Multicausal analysis is essential because monocausal explanations (individual revolt / clerical corruption / sociological phenomenon) each capture a dimension but miss the complex interaction.
Oberman. Luther: Man Between God and the Devil. Yale, 1989.
The Marburg Colloquy (October 1529) was Philip of Hesse's political initiative to unite Lutherans and Reformed against Charles V. Luther and Zwingli agreed on 14 articles out of 15 -- the only failure was the 15th (the Supper). Luther: real corporeal presence in, with and under bread and wine (Hoc est corpus meum taken literally). Zwingli: est = significat, symbolic memorial. Luther left Marburg declaring Zwingli was of 'another spirit.' Consequences: (1) Permanent theological rupture between Lutheranism and the Reformed tradition; (2) Impossibility of Protestant political union; (3) The development of two distinct confessional blocs; (4) Calvin later sought an intermediate position (Wittenberg Concord, 1536 with Bucer). The Marburg rupture remains one of the deepest divisions within Protestantism.
Lienhard. Martin Luther. Labor et Fides, 1983.
Calvin organized Geneva according to a fourfold ministry based on Scripture: (1) Pastors: preaching and administration of the sacraments; (2) Doctors (teachers): theological instruction; (3) Elders: moral oversight of the community (Consistory); (4) Deacons: assistance to the poor and sick. The Consistory (pastors + elders) exercised moral discipline, including excommunication. Calvin faced resistance: the libertines (1553 crisis) challenged his authority. His success in Geneva made it a 'school of Christ' (Knox): Reformed pastors trained and sent throughout Europe. Calvin's international correspondence network made him the most influential Reformer long-term.

Quiz -- The Reformation
8 questions
Q1/8
The 95 Theses of 1517 were originally intended by Luther as:
💡
The 95 Theses (Disputatio pro declaratione virtutis indulgentiarum) were written by Luther as academic propositions for internal theological debate -- not as a popular manifesto. Luther sent them to Bishop Albert of Mainz. The printing press transformed this academic text into a pan-German polemical document within weeks.Q2/8
The Edict of Worms (1521) declared Luther:
💡
The Edict of Worms (May 25, 1521, Charles V): Luther is declared a heretic and put under imperial ban (Reichsacht) -- an outlaw. Anyone can kill him without legal penalty. It is the Elector Frederick III of Saxony who protects him by arranging his kidnapping to the Wartburg.Q3/8
The Peace of Augsburg (1555) recognized:
💡
Peace of Augsburg (September 25, 1555): cuius regio eius religio -- the prince determines the religion of his territory. Only two confessions recognized: Lutheran (Augsburg Confession of 1530) and Catholic. Calvinism is excluded until the Peace of Westphalia (1648). The right of emigration is granted to subjects who disagree.Q4/8
The Marburg Colloquy (1529) failed because Luther and Zwingli could not agree on:
💡
The Marburg Colloquy: 14/15 articles agreed. The 15th (the Supper) was irreconcilable. Luther: real corporeal presence (Hoc est corpus meum = IS). Zwingli: symbolic memorial (est = significat). The political failure to unite Protestants had major strategic consequences against Charles V.Q5/8
Luther's translation of the Bible into German is linguistically significant because:
💡
Luther's translation (NT 1522, complete Bible 1534) used the Saxon chancellery language (gemeines Deutsch) intelligible to all German speakers. He studied regional dialects to find natural expressions ('man muss die Mutter im Haus, die Kinder auf der Gasse fragen'). The Luther Bible contributed decisively to the formation of Hochdeutsch.Q6/8
The death of Zwingli at the Battle of Kappel (1531) is historically significant because:
💡
The death of Zwingli (October 11, 1531) at Kappel marked the end of the Zurich hegemony in the Reformed movement. Bullinger succeeded him. The Zurich-Bern-Geneva axis (later with Calvin) replaced the Zurich-Zurich axis. This also explains why Calvin could impose his theology beyond Zwingli's symbolic position.Q7/8
The Counter-Reformation (Council of Trent, 1545-1563) defined in response to Protestantism:
💡
Council of Trent: response to the Reformation on all contested points. Defined: (1) 7 sacraments; (2) transubstantiation; (3) Tradition co-normative with Scripture (against Sola Scriptura); (4) transformative justification (faith + charity + hope, against Sola Fide); (5) Latin Vulgate authentic. Reformed clergy education in seminaries.Q8/8
The St. Bartholomew's Day Massacre (1572) represents in the history of the Reformation:
💡
St. Bartholomew's Day (24 Aug. 1572): the Huguenot nobility gathered in Paris for the wedding of Henri of Navarre (Protestant) and Margaret of Valois. Catherine de Medici ordered the assassination of Admiral Coligny (Protestant leader), which triggered a general massacre. 3,000-5,000 deaths in Paris, 10,000-30,000 in France. Decisive turning point in the French Wars of Religion.Score
