Chapter 16

The Anabaptist Soul-Sleep Tradition and Pietist Hope

Two Streams That Refused the Magisterial Settlement

In the spring of 1527, a small group of Anabaptists met in the village of Schleitheim, near the Swiss border, and drafted a confession of faith.1 They agreed about baptism, about the sword, about the ban. They said almost nothing about what happens to the dead. Across the next century, that silence would harden into a quiet doctrine. The dead, the Anabaptists came to say, do not pass into Catholic purgatory, and they do not fly straight to be with Christ as the Reformed insisted. They rest. They sleep in Jesus and await the resurrection. Two grand churches had grand answers about death. The Anabaptists had a small one, and they paid for it in blood.

Now jump forward more than a century and a half. Lüneburg, January 1692. Johann Wilhelm Petersen, superintendent of the city's Lutheran churches, is dragged before the consistory. He has been promoting the visions of a young noblewoman named Rosamunde Juliane von der Asseburg, and his preaching has acquired an alarming chiliastic edge.2 The consistory removes him from office and gives him four weeks to leave the city with his family. He retreats to his country estates. He will spend the rest of his life writing — and what he writes, beginning a few years later, is the most sustained Protestant defense of universal restoration that had appeared since the days of Gregory of Nyssa.

These two scenes mark the two great Protestant streams of the long hope after Luther and Calvin: the Anabaptist tradition of soul-sleep, and the Pietist recovery of universal restoration. They are not the same position. One is metaphysical, the other eschatological. One quietly waits; the other ranges across cosmic time. But both grew out of the same soil — Protestants who refused the magisterial settlement and went looking for something older, fresher, more biblical. Both proved fruitful far beyond what their first opponents imagined.

This chapter tells the two stories together — the Anabaptist sixteenth century first, then the Pietist seventeenth and eighteenth centuries, then the threads forward into modern Adventism, into Methodism, into the Blumhardts, and finally into Karl Barth. The long hope did not die in Protestantism with Luther and Calvin. It moved sideways. It found new homes.

The Radical Reformation and Its Pietist Successors

When Luther nailed his theses in 1517, he did not intend to start a movement of separatist communities. He wanted to reform the existing Church. So did Zwingli, and so did Calvin. What we now call the magisterial Reformation was reform carried out with the cooperation of the civil magistrate — princes and city councils who could enforce a single confession across their territory.

The radical Reformation was different. The radicals — the Anabaptists chief among them — wanted nothing to do with state coercion. They argued that the New Testament described a believers' church, gathered voluntarily, marked off from the wider society by adult baptism, by the refusal of the sword, and (often) by community of goods. They were despised by Catholics and Protestants alike. Hundreds were executed in the sixteenth century — drowned, burned, beheaded. Their writings were proscribed.3

The Anabaptists are not one thing. Swiss Brethren, South German radicals, the Dutch followers of Menno Simons, the communitarian Hutterites of Moravia, the wild apocalyptics of Münster — all are called Anabaptists, and they did not agree among themselves about much. A useful distinction comes from the period itself: Stäbler (staff-bearers, the pacifists) and Schwertler (sword-bearers, those willing to use force). After the Münster disaster of 1535, the Stäbler line became dominant. From it descend the Mennonites, the Hutterites, the Amish, and the broader peace-church tradition.4

Pietism was an internal Lutheran reform movement, born more than a century later in the wreckage of the Thirty Years' War. Where the Anabaptists separated from the state churches, the Pietists tried to renew them from within. Philipp Jakob Spener (1635–1705) is the founder. His Pia Desideria, a small book published in 1675, became the manifesto of a movement that would shape eighteenth-century Protestantism more than any other single current. Out of Pietism would come the orphanages of Halle, the missions of the Moravians, the conversion of John Wesley — and the most sustained Protestant universalism between the patristic period and the twentieth century.

What the Figures Actually Said

Hubmaier, Hut, Denck: The First Anabaptist Generation

Balthasar Hubmaier (1480–1528) is the most learned of the early Anabaptists. He had been a Catholic priest, then a Zwinglian, then by 1525 an Anabaptist preacher in Waldshut on the Rhine. His Christian Catechism (Eine christliche Lehrtafel), composed during his imprisonment and published in December 1526, became the most influential single document of early Anabaptist instruction.5 The catechism is, perhaps surprisingly, strongly creedal. Hubmaier insists on the Apostles' Creed. He affirms the resurrection of the body and a final judgment. On the eternal punishment of the unrepentant he is not innovative — he holds, with the medieval tradition, that those who finally refuse Christ are damned.

What is striking is not what Hubmaier says but what he does not say. He spends almost no energy on speculative eschatology. The afterlife is real, judgment is real, but the believer's task is to follow Christ in the present life and trust the Lord for what comes after. This pastoral restraint — eschatology as background rather than foreground — will become characteristic of the peace-church tradition. Hubmaier was burned at the stake in Vienna in March 1528, and his wife was drowned in the Danube three days later. In one of his prison writings he had told his captors that the truth could not be killed by killing him. The catechism circulated for centuries.6

Two of his older contemporaries pushed Anabaptist eschatology in a more visionary direction. Hans Hut (c. 1490–1527) was an apocalyptic preacher who calculated that the Second Coming would arrive in 1528, and he traveled the south German countryside with the urgency of a man who had done the math. Hans Denck (c. 1495–1527) is more interesting for the long hope. Two of his contemporaries — the Lutheran reformer Urbanus Rhegius and the sympathetic pastor Sigelsbach — reported that Denck told them privately that no man or devil was eternally damned, that the blasphemy of the damned would end in time.7 Whether Denck was a settled universalist or merely a hopeful one is debated to this day. What is not debated is that magisterial Protestants accused early Anabaptism of universalism, and that they were not entirely making it up.

Note: The Universalism Question in Early Anabaptism

The most careful modern study, Morwenna Ludlow's 2004 essay in the Journal of Ecclesiastical History, argues that Denck's universalism is overstated by his accusers and that he held at most a hopeful universalism. A more recent study by Andrew Raines (Duke, 2021) reaches the opposite conclusion, taking the Rhegius account seriously and reading Denck as a true universalist with limited but real Anabaptist disciples. The historical question remains open. What is clear is that sixteenth-century magisterial Protestants treated Anabaptist universalism as a real and recurring problem — not an invention.

Soul-Sleep and the Anabaptist Doctrine of the Intermediate State

The Anabaptist position with the longest historical legacy was not universalism but psychopannychism — pronounced "sy-ko-pan-NIK-izm," from Greek roots meaning "all-night-sleep of the soul." The teaching, in its strict form, is that the dead are unconscious between death and the resurrection. They are not in heaven, they are not in hell, they are not in purgatory. They sleep in Christ and await the trumpet.

The position is older than Anabaptism. Variants of it appear in some early Syriac writers and in some medieval mystics. Luther himself, on several occasions, spoke of the dead as "asleep" until the resurrection — though Luther also said other things, in other places, that imply a conscious intermediate state. The tension in Luther was real, and his theological heirs took it in different directions.8 But it was the Anabaptists who pressed soul-sleep into a fully argued doctrine.

The young John Calvin, in 1534, wrote his first theological work against them. Psychopannychia — drafted in Latin at Orléans, and finally published in Strasbourg in 1542 — is a passionate defense of the conscious intermediate state.9 Calvin calls the soul-sleep doctrine a cancer and an insanity. He thinks it threatens the whole structure of Christian comfort: if believers do not go to be with Christ at death, then Paul's longing to "depart and be with Christ" (Phil. 1:23) makes no sense.

Calvin's vehemence is itself useful historical evidence. He clearly thought the Anabaptist position was spreading, and that it had become a real challenge to the developing Reformed consensus. He was right. Across the next four centuries, soul-sleep in some form would be embraced by Socinians, by some Polish Brethren, by Christadelphians, by the Adventist family of churches, and by a substantial minority of modern conditional-immortality advocates. Anabaptist psychopannychism is the seed from which much of this would grow.

Menno Simons and the Pastoral Quiet

By the time Menno Simons (c. 1496–1561) emerged in the late 1530s, the Anabaptist movement was reeling from the Münster catastrophe — the violent apocalyptic takeover of the city of Münster in 1534–35 that ended in slaughter and gave magisterial authorities a permanent excuse to associate all Anabaptists with chaos. Menno, a former Catholic priest in Friesland, took up the work of regathering the Stäbler — the peaceful Anabaptists — and giving them a settled identity.

His major work, The Foundation of Christian Doctrine (Dat Fundament des Christelycken leers), appeared in 1539–40.10 It is more pastoral than systematic. Menno wants to teach repentance, faith, baptism on confession, the discipline of the gathered church, separation from violence, and the imitation of Christ. On the fate of the dead he is restrained — he speaks of the dead resting with Christ until the resurrection, language that could be read either as soul-sleep proper or as a softer "soul rest."

This restraint is itself a tradition. The Mennonites, the Hutterites, and (later) the Quakers and the broader peace-church tradition will all, on the whole, downplay speculative eschatology. The fight for them is not over who goes where after death but over how the gathered community lives as the body of Christ here and now. Eschatology hovers in the background, real but not central. The pastoral character of Anabaptist eschatology is itself a contribution to the long hope — a refusal to over-specify what only God knows.

Spener, Francke, and the Pietist Beginnings

Now move to Frankfurt-am-Main, 1675. Philipp Jakob Spener, a thirty-nine-year-old pastor, has been asked to write a preface to a new edition of Johann Arndt's True Christianity. Spener takes the assignment and produces something larger than a preface. He calls it Pia Desideria — "pious longings," or as the German subtitle ran, "heartfelt desire for God-pleasing reform." Within six months it has been republished as a stand-alone book.11 Pietism is born.

Spener's six proposals — more serious Bible study by the laity, small-group meetings (collegia pietatis), practical Christianity over scholastic dispute, an irenic spirit, reformed preaching, and a renewed sense of Hoffnung besserer Zeiten ("hope for better times") — became the program of the movement. The last is where the long hope quietly enters. Spener was not a universalist. But he refused the Lutheran orthodox consensus that the world's situation could only get worse until Christ's return. He believed God still had a great work to do in history — including the conversion of the Jews and a deeper Christianization of the nations.

August Hermann Francke (1663–1727), Spener's protégé and the great organizer of the movement at Halle, made Pietism practical — orphanages, schools, missions, a printing house, a Bible institute.12 The "hope for better times" became programmatic. From this fertile soil, more radical Pietist eschatologies emerged. Some of them went very far indeed.

The Petersens and Mystērion Apokatastaseōs Pantōn

Among the most far-reaching was the work of Johann Wilhelm Petersen (1649–1727) and his wife Johanna Eleonora Petersen, née von Merlau (1644–1724). They had married in 1680. They were both Spener's friends. Johann Wilhelm had risen quickly — pastor at Hanover, court preacher at Eutin, then in 1688 superintendent of Lüneburg.13 They were also both drawn to chiliasm — the belief in a literal future thousand-year reign of Christ — and increasingly to the visions of a young noblewoman named Rosamunde Juliane von der Asseburg, whom they took into their home and whose "testimonies" they published.

In January 1692 the Lüneburg consistory had had enough. Petersen was deposed and given four weeks to leave with his family. The deposition was technically over chiliasm and the von der Asseburg matter; what followed afterward was more consequential than what was being suppressed.14

Beginning in 1695, on their estates at Niederndodeleben near Magdeburg, the Petersens moved from chiliasm to apokatastasis — pronounced "ah-poh-kah-TAH-stah-sis," the Greek word for "restoration of all things" that Peter uses in Acts 3:21. They read Origen. They read Gregory of Nyssa. They corresponded with the English mystic Jane Lead and the broader Philadelphian circle.15 In 1698 they published, anonymously at first, The Eternal Gospel of the Universal Return of All Creatures. Then, between 1700 and 1710, came the three folio volumes of Mystērion Apokatastaseōs PantōnThe Mystery of the Restoration of All Things.16 It was the most sustained Protestant defense of universal restoration that had appeared since the patristic period.

Primary Source: Petersen on the Pastoral Cost of Eternal Damnation

In the second volume of Mystērion, Petersen turns from his biblical and patristic arguments to a pastoral one. He asks his Lutheran readers a question he plainly expects to sting: What fruit has the doctrine of eternal damnation borne up till now? Has it made men more pious? His answer is that it has not — that when serious people have grasped the cruel disproportion between finite human sins and an infinite punishment, many of them have ended by believing nothing at all. The doctrine of ECT, on Petersen's reading, was driving the educated classes of Lutheran Germany not into deeper devotion but into private atheism.17

— J. W. Petersen, Mystērion Apokatastaseōs Pantōn, II.222 (1700–1710)

The Petersens' argument was Origenist in its broad shape and biblicist in its surface. They argued that the New Testament's "eternal" language refers to ages rather than absolute endlessness; that God's saving will revealed in 1 Timothy 2:4 cannot finally be frustrated; that Christ's victory over sin and death must extend to every rational creature. Gottfried Wilhelm Leibniz read their work and was impressed enough to begin a correspondence with Johann Wilhelm in 1706.18 The Petersens were not isolated. The anonymous Everlasting Gospel of Georg Klein-Nicolai, also from around 1700, would be translated into English in the eighteenth century and would shape the early American universalist Elhanan Winchester. Their restorationism crossed the Atlantic almost as soon as it crossed the Channel.

Oetinger, Bengel, and the Württemberg Stream

Württemberg — the Lutheran duchy of southwestern Germany centered on Stuttgart and Tübingen — produced its own Pietist trajectory, more cautious in its universalism than the Petersens, but more lasting in its institutional influence.

Friedrich Christoph Oetinger (1702–1782) studied at the Tübinger Stift from 1722 to 1728 and absorbed Jakob Böhme, the Christian Kabbalah, Newton, and Leibniz in roughly equal measure.19 His Theologia ex Idea Vitae Deducta — "theology drawn from the idea of life" — and his other writings sketched a Christological universalism that ran beneath the surface of Württemberg piety for generations. Oetinger was repeatedly investigated by ecclesiastical superiors and repeatedly protected by the Duke of Württemberg, who valued him. He died a prelate at Murrhardt.

Johann Albrecht Bengel (1687–1752) is the more public figure. Bengel was a textual scholar of the first rank — his critical edition of the Greek New Testament prepared the way for modern textual criticism — and his commentary, the Gnomon Novi Testamenti (1742), is still consulted today.20 Bengel's prophetic system was elaborate. He calculated, on the basis of his reading of Revelation, that the millennium would begin in 1836.21 His eschatology was a "wider hope": a multi-stage divine economy through which God works to bring all things to their end in Christ. He did not call himself a universalist, but his system left wide doors open.

The crucial fact about Bengel is downstream. John Wesley carried Bengel's Gnomon on his preaching circuits. Wesley translated most of it into English and incorporated it into his own Explanatory Notes on the New Testament.22 Through Wesley, Bengel's eschatology — chiliastic, hopeful, expansive — entered Methodism. Through Methodism it entered the English-speaking evangelical world. The hidden inheritance of Württemberg Pietism is more pervasive than most modern evangelicals realize.

The Blumhardts and the Watchword "Jesus Is Victor"

One more stop in this chain. In the early 1840s, in the village of Möttlingen, the Württemberg pastor Johann Christoph Blumhardt (1805–1880) presided over the long, exhausting, and finally successful exorcism of a young woman named Gottliebin Dittus. As the deliverance came, she cried out: "Jesus ist Sieger!" — "Jesus is Victor!"23 That phrase became the watchword of Blumhardt's later ministry. It would also become, a century later, the watchword of Karl Barth.

A revival followed. In 1852 the Blumhardts moved to a healing community at Bad Boll, in Württemberg, that drew visitors from across Europe.24 Johann Christoph's son, Christoph Friedrich Blumhardt (1842–1919), eventually took over the work and turned it in a more radical direction — joining the Social Democratic Party, refusing the German national church's accommodations to militarism, and preaching a Christ whose reign is for the whole creation. The younger Blumhardt's universalism was unmistakable. The kingdom of God for him was not a salvage operation rescuing souls from a doomed world; it was the renewal of the whole earth and the gathering of all people to Christ in the end.25

Insight: From Bad Boll to Basel

Eduard Thurneysen, a young Reformed pastor and Karl Barth's closest friend, brought Barth to Bad Boll in the early years of their break with liberal theology. Barth would later write three separate essays on the Blumhardts. The motto "Jesus ist Sieger" would become the title of the climactic § 69.3 of Church Dogmatics IV/3, the section that more than any other has fueled the modern debate about whether Barth's theology is finally universalist. The Pietist long hope, refined through two centuries, walked directly into twentieth-century Reformed dogmatics and reshaped it.26

Reception and Controversy

The reception story has two distinct arcs.

The Anabaptist arc was one of brutal external repression and slow internal consolidation. In the sixteenth century, Anabaptism was a capital crime in much of Europe. The Mennonites and Hutterites who survived did so by withdrawing — to the rural Netherlands, to Moravia, to Polish-Prussian Vistula, eventually to South Russia and North America. Their doctrine of the intermediate state stayed quietly in their confessions and catechisms. When Calvin's Psychopannychia finally appeared in print in 1542, it functioned for the Reformed tradition as a permanent immunization against soul-sleep. Reformed orthodoxy never seriously revisited the question. The Lutheran tradition, more ambivalent because of Luther's own occasional language of "sleep," eventually settled on the conscious intermediate state — but never with Calvin's polemical edge.

The longer Anabaptist arc came in the nineteenth century. Adventism — first William Miller's movement, then the Seventh-day Adventists under Ellen White — recovered soul-sleep, often combined with conditional immortality (the destruction rather than the eternal torment of the finally impenitent). The Christadelphians did the same. So did a smaller stream of British conditionalists in the wake of Edward White. Modern Adventism alone now numbers more than twenty million adherents. The Anabaptist seed of psychopannychism — once a marginal Reformation-era position — is now one of the most widely held intermediate-state doctrines among living Protestants. The full story belongs to Chapter 20.

The Pietist arc is different. The Petersens were never executed. They were deposed, censured, and gradually marginalized. But because they were Lutheran insiders writing in German, they were never extinguished. Mystērion Apokatastaseōs Pantōn circulated quietly. Klein-Nicolai's Everlasting Gospel, translated into English by the Pennsylvania printer Christopher Sauer, became foundational for the early American Universalists; Elhanan Winchester read it carefully and built much of his case on it.27 Through Bengel, Pietist eschatology entered Methodism and shaped Wesley's openness to a wider hope. Through the Württemberg Stift, it formed Hegel, Schelling, and a long line of nineteenth-century German theologians whose intellectual ancestry runs through Oetinger and Bengel. Through the Blumhardts, it entered Karl Barth, Emil Brunner, and Jürgen Moltmann — three of the most influential twentieth-century Protestant theologians, all of whom inherited from the Württemberg Pietists a refusal of the strict eternal damnation framework.

Both arcs include episodes of mainstream backlash. Calvin's Psychopannychia is one. The Lutheran formal response to the Petersen revival was another, with the universalism of Origen named in Article XVII of the Augsburg Confession now invoked against the Petersens by the consistorial authorities of Hanover, Saxony, and Hesse. Eighteenth-century Württemberg consistories investigated Oetinger more than once. Pietist universalism never gained official approval anywhere in mainstream Lutheranism. But it never died either. It traveled along less visible institutional routes — through pious laymen, through translated tracts, through the libraries of pastors who admired Bengel's biblical scholarship and (sometimes quietly) absorbed his eschatology along with it.

Assessment — What We Can and Cannot Conclude

What did these two streams actually teach? Where the historical record is contested, what can we say with confidence, and what remains debated?

The Anabaptist soul-sleep tradition is well documented. Psychopannychism was held in multiple forms. The strict form taught that the soul has no conscious existence between death and the resurrection. A softer form held that the dead "rest" with Christ without active awareness — they are with Christ in the way that a sleeping person is in the room with their friend, but they are not awake to it. Which form a given Anabaptist confession holds is sometimes hard to say without close reading.28

We should also distinguish soul-sleep from conditional immortality. They are not the same. Soul-sleep is a position about the intermediate state — what is happening between physical death and resurrection. Conditional immortality is a position about the final state — what happens to the finally impenitent. A person could in principle hold strict soul-sleep and still believe the resurrected wicked endure eternal conscious torment after the resurrection. The Adventist tradition combined the two positions; modern Rethinking Hell conditionalists, treated in Chapter 28, do not all share the soul-sleep half. But the historical convergence is real, and the Anabaptist intermediate-state doctrine was one of its sources.

The Pietist universalism of the Petersens is also well documented. Mystērion Apokatastaseōs Pantōn is in three folio volumes, in print, with marked Origenist and Gregorian sources. The Petersens believed in a final restoration of all rational creatures, including the devil. Their argument was biblical first, philosophical second. They cited 1 Timothy 2:4, Colossians 1:20, 1 Corinthians 15:28, Acts 3:21, and a range of Old Testament restoration texts, and they answered the standard objections at length. Whether one finds their case persuasive is a different question from whether they made it.

Common Objection: "These Movements Were Fringe"

By a head-count of European magisterial Protestants in 1700, yes, the Petersens were marginal and the Anabaptists were criminalized. By a head-count of living Christians in the early twenty-first century, the descendants of these movements — Mennonites, Hutterites, Amish, Adventists, classical Methodists, modern hopeful universalists, the wider Barthian and Moltmannian streams — represent tens of millions of believers and some of the most theologically active currents in contemporary Christianity. The "fringe" has won the long demographic argument. The historical lesson is that the magisterial settlements of the sixteenth century were not the final word on Protestant eschatology. Underneath the textbook "Lutheran position" and the textbook "Reformed position" there were always alternative streams that refused the strict eternal-damnation framework. They were sometimes marginal. They were never absent.

The harder lesson is about how traditions hide and resurface. Anabaptist soul-sleep was suppressed by both Lutheran and Reformed authorities for two centuries, then came back in nineteenth-century Adventism and in the modern conditionalist conversation. Pietist universalism was suppressed by the Lutheran consistories, then came back through Methodism, through Württemberg piety, through the Blumhardts, through Barth. Position and institution can be decoupled for a very long time. A doctrine that lacks an official church to defend it can still travel — through translated tracts, through pious laypeople, through the personal libraries of unfashionable pastors. The long hope traveled that way for centuries.

Conditional immortality, as we will see in Chapter 20, has a long pedigree in the patristic period. Postmortem opportunity has a long pedigree in the patristic descent tradition (see Chapter 8). Universal restoration has a long pedigree in the patristic East (see Chapter 9). The Anabaptist and Pietist streams are where these older trajectories re-enter post-Reformation Protestantism — not as imports from outside, but as recoveries by sincere students of the Bible.

Why This Matters

Modern American evangelicals have largely inherited Reformation-era eschatology through the magisterial channels — through the Reformed confessions, through Lutheran orthodoxy as transmitted by the seventeenth-century scholastics, through eighteenth-century Calvinist preaching, through the Princetonian theology of the nineteenth century. From inside that inheritance, it can look as though the strict eternal-damnation framework is simply what Protestants believe. The Anabaptists, when remembered at all, get filed under "history of baptism." The Pietists, when remembered, get filed under "history of evangelism." Their eschatologies get filed under "forgotten."

That filing is a mistake. Anabaptist soul-sleep is not a curiosity of sixteenth-century radicalism. It is the metaphysical root of one of the largest living Protestant movements (Seventh-day Adventism) and of the modern conditional-immortality conversation. Pietist universalism is not a curiosity of late-seventeenth-century radicalism either. It is the eschatological root of much of the most influential twentieth-century Protestant theology. To remember these movements is to remember that Protestantism has always contained streams that refused the strict ECT default — streams that did not need to wait for twentieth-century existentialism or postmodernism to question the magisterial settlement, but that questioned it from inside their own century, with their own Bibles, and at considerable personal cost.

Key Argument

The Anabaptist soul-sleep tradition and the Pietist universalist tradition are not late innovations or theological eccentricities at the edge of Protestant history. They are post-magisterial alternatives that emerged within the first century and a half after Luther, that were defended at considerable personal cost by serious students of Scripture, and that have shaped — quietly but pervasively — the modern Protestant landscape on the doctrine of last things. The "modern innovation" charge against post-deadline eschatology cannot survive contact with these streams.

The Petersens lost a superintendent's salary and a city's social standing for what they wrote. Hubmaier lost his life. Menno was hunted for years. Christoph Blumhardt was repeatedly investigated by the Württemberg church authorities. None of them were silly. None of them were marginal in any sense except the political. They are part of the long hope. They remind us that the question of what the Christian tradition teaches about the fate of the dead has, since the sixteenth century, always had more than one Protestant answer. The long hope did not die in Protestantism. It moved sideways, and it lived.

Journal of Ecclesiastical History 55, no. 2 (April 2004): 257–274, argues that Denck was at most a hopeful universalist and that his accusers exaggerated his views. Andrew L. Raines, "'The Word of God in the Hearts of All Men': Hans Denck and Anabaptist Universalism" (Honors thesis, Duke University, 2021), takes the Rhegius account seriously and concludes that Denck was indeed a settled universalist.

14. The Lüneburg consistorial proceedings cited Petersen for his promotion of the von der Asseburg revelations and for chiliasm. Universalism is not the named cause of deposition. The Petersens moved from chiliasm to apokatastasis only after their removal to Niederndodeleben in 1693, with the first written defenses appearing in 1695 and the first published treatise (the anonymous Ewiges Evangelium) in 1698.
