A Reformation Sourcebook

Based on the provided sourcebook, the main topics covered center on the multifaceted debates and events of the Reformation era, structured as follows:

Late Medieval Background: Explores the state of Christianity before Martin Luther, including debates over papal authority (conciliarism vs. papalism), late medieval heresies (John Wyclif and Jan Hus), the tension between scholasticism and humanism, and various forms of lay piety like pilgrimages and the veneration of relics.
The Thought and Development of Martin Luther: Details the emergence of Luther’s theology, starting with the indulgence controversy and progressing to his core doctrines such as “justification by faith alone,” the “priesthood of all believers,” and his rejection of the Catholic sacramental system. It also covers his debate with Erasmus on free will.
The Radical Reformation and Social Unrest: Examines the more radical wings of the movement, including Andreas Karlstadt’s push for rapid liturgical reform and iconoclasm, Thomas Müntzer’s spiritualism, and the social revolution of the German Peasants’ War.
Zwingli and the Reformed Tradition: Covers the Reformation in Zurich led by Ulrich Zwingli, the theological rift with Luther over the Eucharist at the Marburg Colloquy, and the rise of the Swiss Anabaptist movement.
French Reform and Calvinism: Traces evangelical efforts in France, from the Meaux group to the Affair of the Placards, and the subsequent development of John Calvin’s thought and moral discipline in Geneva.
The English Reformation: Details England’s unique break from Rome under Henry VIII, the further Protestantization under Edward VI, the Catholic restoration under Mary I, and the Elizabethan settlement that birthed Anglicanism while facing Puritan opposition.
The Catholic (Counter) Reformation: Highlights the Roman Catholic Church’s institutional response, primarily through the Council of Trent’s doctrinal clarifications and the rise of new religious orders like the Jesuits (Society of Jesus), alongside a resurgence in mysticism.
Wars of Religion: Documents the actual military conflicts sparked by religious division, including the Wars of Kappel in Switzerland, the Schmalkaldic War in Germany, and the French Wars of Religion (notably the St. Bartholomew’s Day Massacre).
Cultural and Social Impact: Analyzes how the Reformation changed daily life and social customs, including baptismal and funeral rites, practices like fasting and carnival, the use of music in worship, and shifting attitudes toward women, marriage, slavery, and the Jewish community.

The core theological differences between Martin Luther and Ulrich Zwingli, particularly regarding the Eucharist, are primarily illustrated through the following documents:

The Debate at the Colloquy of Marburg (1529): This is a hybrid account of a formal meeting between Luther and Zwingli where they attempted to reach a theological agreement. The debate highlights their fundamental disagreement over the nature of the Eucharist:
- Luther’s Position: He insisted on the real, corporeal presence of Christ’s body and blood in the bread and wine, based on a literal reading of the words “This is my body”.
- Zwingli’s Position: He argued for a symbolic or figurative understanding, maintaining that the bread and wine merely represent Christ’s body and blood, and that Christ’s human nature is in heaven and cannot be physically present on earth.
The Babylonian Captivity of the Church (1520): In this treatise, Luther attacks the Catholic sacramental system and provides his early views on the Eucharist. While he rejects transubstantiation, he argues for the presence of Christ’s real flesh and blood in real bread and wine. This document serves as a foundational text for Luther’s position that Zwingli would later challenge.
Concerning Choice and Liberty Respecting Food (1522): This document by Zwingli illustrates his broader approach to reform, which was more thorough than Luther’s in areas of church practice. It highlights his belief in “Christian freedom” regarding religious fasts, a principle that both he and Luther initially shared but applied with different degrees of rigor to liturgical practices.
Luther’s “Invocavit Sermons” (1522): Although primarily directed at Andreas Karlstadt, these sermons illustrate Luther’s cautious approach to liturgical reform and his disagreement with the rapid, radical removal of traditional elements like images and the Mass. Zwingli’s Reformed tradition, by contrast, advocated for a more thorough removal of such items, which is another key area where the two movements diverged.

The main positions of the Anabaptists are detailed in the Schleitheim Confession of Faith (1527), to which Ulrich Zwingli provided a point-by-point rebuttal in his Refutation of the Tricks of the Catabaptists (1527).

Main Positions of the Anabaptists

The Schleitheim Confession outlines seven fundamental articles:

Believers’ Baptism: Baptism should only be given to those who have learned repentance, amended their lives, and truly believe their sins are removed by Christ. This explicitly excludes infant baptism.
The Ban (Excommunication): The church should use the ban for those who have committed themselves to God but later fall into error or sin. They should be privately admonished twice before being openly disciplined or banned.
Breaking of Bread: Only those united by believers’ baptism can participate in the Lord’s Supper. This excludes those who still follow “the world” or “the devil”.
Separation from Evil: Believers must completely separate themselves from the “abominations” of the world, including all “popish and antipopish” church services, civic affairs, and drinking houses.
Pastors: The church should have pastors who are well-regarded by those outside the faith, whose duties include teaching, disciplining, and leading in prayer.
Non-Resistance and the Sword: While the “sword” (secular authority) is ordained by God to punish the wicked, it is outside the “perfection of Christ”. Therefore, Christians should not use the sword for defense or serve as magistrates.
The Oath: Christ prohibited all swearing of oaths.

Zwingli’s Response

Zwingli refutes these positions primarily by arguing they lack scriptural and historical depth:

On Baptism: Zwingli argues that infant baptism has been the custom since the time of the apostles and was mentioned by early church fathers like Origen and Augustine. He labels the Anabaptist view “pseudo-baptism”.
On the Ban: He cautions against rash excommunication, citing Christ’s parable of the tares, which suggests some things should be tolerated until the final harvest.
On Separation: Zwingli accuses Anabaptists of using separation to lure people into secret, nighttime meetings where he claims they engage in immoral behavior and “spiritual marriage with carnal copulation”.
On the Sword and Magistracy: He rejects the idea that a Christian cannot be a magistrate, noting that biblical figures like Cornelius the centurion were baptized without being told to resign their office. He views the Anabaptist position as a “monkish” assumption of absolute perfection that is impossible in this life.
On the Oath: Zwingli maintains that Christ only forbade “light” or “off-hand” swearing in ordinary discourse, not the official oaths required by magistrates for legal order.

This sourcebook, edited by Michael Bruening, analyzes the Protestant and Catholic Reformations through a collection of primary documents that illustrate the period as an “Age of Debate”. Rather than presenting a single narrative, the book explores the era by grouping documents into thematic chapters that highlight formal and informal disputes over religious authority, practice, and social order.

Core Theological and Institutional Debates

Religious Authority: The book traces the shift from late medieval papalism and conciliarism to the Protestant focus on sola scriptura (Scripture alone). It contrasts Martin Luther’s “priesthood of all believers” with the Catholic Church’s defense of a distinct, external, and hierarchical priesthood.
Justification and Sacraments: A central theme is the debate over justification by faith alone versus the necessity of good works and the Catholic sacramental system. Significant focus is given to the Eucharist, comparing Catholic transubstantiation with Luther’s real presence and Ulrich Zwingli’s symbolic view.
Free Will: The text highlights the intellectual rift between the humanist Erasmus, who argued for human cooperation with grace, and Luther, who insisted on the “bondage of the will” in matters of salvation.

Internal Conflicts and Radical Movements

The Radical Reformation: The collection documents the rise of “fanatics” or radicals, such as Andreas Karlstadt and Thomas Müntzer, who pushed for faster, more extensive reforms in liturgy and social structures than Luther was willing to support.
Anabaptism: In Switzerland, the book examines the rise of the Anabaptists, who focused on adult believers’ baptism and separation from secular society, a movement Zwingli vigorously opposed.

Geographic and Political Developments

National Reformations: Individual sections analyze how the movement varied across Europe, including John Calvin’s implementation of strict moral discipline in Geneva, the top-down state-driven Reformation in England under Henry VIII, and the struggles of French evangelicals.
Religious Warfare: The book provides accounts of the military consequences of these theological divides, such as the Swiss Wars of Kappel, the German Schmalkaldic War, and the bloody French Wars of Religion, including the St. Bartholomew’s Day Massacre.
