The Reformation at 500

Introduction

In January 2025, we will mark five hundred years since the free-church movement began to take shape in the form of a body of believers who voluntarily joined together through baptism upon their confession of faith in Christ. On January 21, 1525, a small group of laypeople in the Alpine city of Zurich gathered for prayer and Bible study in a citywoman’s home, apart from the parish church and its state-sanctioned clergy. It ended with one member asking another to baptize him “upon his faith,” representing his belief that his faith made the baptism an important moment in his life as a follower of Christ, rather than the official status of the baptizer or the links that his society made between baptism and recognition by the state.         

The idea of a free church, loosed from reliance on the coercive potential of the state, was by no means new; it had been present throughout the centuries since the church began to experience the privileges of imperial patronage in the late Roman Empire.  But popular excitement about reforming the Church in the 1520s—now that common people in Europe had easier access to printed copies of the Scriptures in their native languages—emboldened some reformers to imagine restarting a church that would be more like the one they read about from the days of the apostles. The proponents of a free church were guided by the Great Commission to preach the Gospel and make disciples, and then to baptize and train members in obedience to the commands of Christ. They believed the Great Commission implied that the church would not be composed of all people born within the territory of a Christian ruler, but rather of people who consciously decided to repent of their sins and lead distinctive lives in pursuit of conformity with Christ.   

To help our college community recall God’s provisions for this movement, even in the midst of persecution and the leadership failings that are so common to human nature, we will be including a new feature in our weekly emails for the next few years: a developing “timeline” that will track events in the free-church movement as they happened 500 years ago.  

The entries will draw on Reformation-era transcripts of theological debates and trials, letters and treatises of reformers, and chronicles of eye-witnesses to give us a “real-time” sense of the relationship of key events as they unfolded precisely 500 years ago.  We hope you find it a valuable contribution to your appreciation of church history and even your devotional life.

October 26-28, 1523: Zurich Holds Second Doctrinal Disputation

At the “Second Doctrinal Disputation” of Zurich, Conrad Grebel and Simon Stumpf challenged Ulrich Zwingli’s caution in reforming the Mass and removing images from churches. While Zwingli deferred to the Zurich town council’s authority, his challengers believed that church leaders should independently reform worship based on New Testament principles, setting the stage for a split from Zwingli’s more politically measured approach.

Late October – December, 1523: Zurich Council Issues Mandates to Preserve Public Peace over Worship

Zurich’s town council attempted to balance conservative and reformist views by restricting new religious imagery in churches while respecting existing artworks, and by mandating that the Mass continue unchanged. However, as tensions rose, reform supporters began disrupting services, prompting stricter council measures to prevent conflict, but also an openness to some congregational decision-making on worship matters.

November – December, 1523: Zurich Council Expels Simon Stumpf and Zwingli Rejects a Separate Church

In November 1523, the Zurich Council deposed Simon Stumpf from his pastorate after he advocated for church practices to be decided by clergy rather than the Council, which led to his eventual banishment from Zurich. Ulrich Zwingli, rejecting Stumpf’s vision of a separate “pure” church, insisted on a unified territorial church that included both devout and less devout members, citing Christ’s parables to argue for tolerance within a single community of believers.

Late 1523 – August 1524: Home Bible study group forms in Zurich / Zurich Bible is published / Conrad Grebel writes to Thomas Müntzer

A group of laypeople, including Conrad Grebel, started meeting in Zurich to study the Bible as well as the writings of evangelical preachers. Perceiving Andreas Karlstadt and Thomas Müntzer as the “purest proclaimers and preachers” of the “divine word,” Grebel wrote a letter to Müntzer in which he explained his vision of biblical worship most fully and advocated for Christian non-resistance against a backdrop of brewing peasant revolts. Read More.

August – November, 1524: Andreas Karlstadt Debates Luther and Publishes “Whether One Should Proceed Slowly”

Andreas Karlstadt, a reformer in Saxony respected by Conrad Grebel and his circle in Zurich, is banished after he and Martin Luther reach an impasse on the extent to which churches needed to be cleansed of icons and reenvision the sacraments of the eucharist and baptism. From his exile, Karlstadt publishes a pamphlet calling for clergy to be the vanguard of change by removing images from Christian worship spaces regardless of lay rulers’ or other lay people’s desire to continue old practices. Read More.

September – November, 1524: Balthasar Hubmaier Publishes “On Heretics and Those Who Burn Them” and Returns to His Pastorate in Waldshut

Balthasar Hubmaier, a talented preacher in southern Germany, argued against suppressing heretics with physical force, instead advocating for dialogue and discipline within the church. His tract “On Heretics and Those Who Burn Them” expressed faith that Christ had commissioned the church with sufficient tools for maintaining proper doctrine; it did not need to turn to the state’s remedies in criminal law to preserve the health of the body of Christ.  Read More.

December 6, 1524: Zwingli Holds First Discussion on Baptism and Writes a Treatise “Against Those Who Cause Rebellion”

Objectors to infant baptism in Zurich hold the first of several meetings with Ulrich Zwingli and other clerical leaders specifically about baptism. Zwingli comes away from the meeting viewing their position on baptism as linked to Grebel’s earlier push for a separatist church. He admonishes the objectors that their separatist disposition was rooted in spiritual pride and a lack of love for neighbors. Read More.

December 13, 1524: Zwingli Holds Second Discussion on Baptism and Felix Mantz Writes “Petition of Defense” for Believers’ Baptism

Conrad Grebel and others who were critical of infant baptism had a contentious meeting with the leading clergy in Zurich. In response, Felix Mantz wrote a petition to the Zurich Council, arguing that baptism should follow personal repentance for sins and a desire to live a reformed life with Christ. It was the clearest rationale for believers’ baptism that Grebel’s circle produced. Read More.

January 17, 1525: Zurich Holds First Disputation on Baptism

The Zurich Council held a formal disputation on the matter of baptism, giving Conrad Grebel, Felix Mantz, and Wilhelm Reublin a chance to argue for believers’ baptism alone. But the Council supported Zwingli’s arguments for infant baptism and followed up the disputation with a threat of banishment for anyone who failed to have their newborn children baptized. Read More.

January 21, 1525: Prayer Service Revives Believers’ Baptism

On the evening of January 21, 1525, a group of about fifteen critics of infant baptism met in Zurich to pray after several of their colleagues were ordered into exile. There they felt led to revive the practice of believers’ baptism. Read More.

January 22-30, 1525: An Anabaptist Congregation Sprouts in Zollikon, but Arrests Quickly Follow

In the week following the January 21 prayer meeting in Zurich, a congregation of people excited about believers’ baptism began to commune frequently and share in intimate fellowship in the village of Zollikon. But on Jan. 30, the cantonal government imprisoned 25 individuals in an effort to squelch the growth of a movement that it feared would divide the state church. Read More.

January 30 – February 8, 1525: Zollikon Anabaptists Defend Rebaptism in Prison

On February 8, the 25 imprisoned Anabaptists from Zollikon were released after their examinations by the Zurich town council’s special delegation. Among the conversations they had in prison was an interview with Ulrich Zwingli over the scriptural precedent for rebaptism. The Anabaptists referred to early believers’ action in Acts 19 to show precedent for undertaking a new baptism upon confession of faith in Jesus. Read More.

Mid-February, 1525: Hans Brötli Writes Letters from Exile to the Zollikon Congregation

After complying with Zurich’s order of banishment, Hans Brötli and his family journeyed with Wilhelm Reublin to the northern Swiss canton of Schaffhausen, where they found hospitality and a receptive audience for Anabaptist preaching among local villagers. Brötli’s continued to support his young congregation in Zollikon, however, with two letters based on the models of the apostolic epistles, professing great love for the Christian fellowship and constancy in the faith that they shared. Read More.

February 24-26, 1525: Blaurock is Released from Prison and Baptizes More in Zollikon

On the Sunday after George Blaurock’s release from prison, around 200 people in Zollikon gathered in two house-church meetings, where they heard Blaurock preach and witnessed the baptisms of several more women and men. Read More.

February 27 – March 1, 1525: Upper Swabian Peasants Call for Congregational Authority over Pastors and Tithing in their “Twelve Articles” 

South German peasants mobilizing for armed rebellion against their lords held an assembly of their leaders, who published a manifesto summing up their grievances and visions for reform. Among them, they set out demands for congregational elections of pastors and management of tithes by congregationally-elected officials. Both of these reforms would have significantly reduced the role of the state in church life. Read More.

March 8-15, 1525: Zollikon Congregation Grows with Eighty Baptisms and Blaurock Is Imprisoned Again 

It was an eventful week among the vibrant Zollikon congregation of Anabaptists, as eighty new people asked for baptism during meetings there. The congregation’s members were meeting frequently, sharing in the Lord’s Supper even outdoors amid an orchard. But the growing meetings soon came to the attention of the Zurich Council, which began planning a crackdown. Read More.

March 16, 1525: Nineteen Members of the Zollikon Congregation are Arrested and Interrogated

Zurich officers rounded up most of the men in Zollikon who had been baptizing adults in the region and brought them to Zurich for questioning. Zwingli personally tried to convince some of the prisoners to accept the instruction of the church regarding baptism. In the midst of this pressure to conform to the state church’s practices, one prisoner wrote a touching letter to the Zollikon congregation expressing his desire to stay strong in the faith and praying for God to raise up someone to baptize and teach in the absence of the congregation’s first leaders.
