Before 1515, Karlstadt was a proponent of a modified
scholasticism. He was a "secular" cleric with no official ties to any
monastic order. His beliefs were challenged during his stay in Rome, where he alleges he saw large-scale corruption in the
Catholic Church, and on a document dated 16 September 1516 he wrote a series of 151 theses. (These should not be confused with Luther's
95 theses (1517) that attacked
indulgences.) In 1519,
Johann Eck challenged Karlstadt to the
Leipzig Debate. There, Eck debated with Luther as well as Karlstadt. On 15 June 1520 Pope Leo X issued the
papal bull Exsurge Domine that threatened Luther and Karlstadt with
excommunication, and condemned several of their theses. Both reformers remained steadfast, and excommunication followed in 1521 in the
papal bull Decet Romanum Pontificem. After the
Diet of Worms (January–May, 1521), and while Luther was hiding at
Wartburg Castle, Karlstadt worked toward reform in Wittenberg. On Christmas Day 1521, he performed the first
reformed communion service. He did not elevate the elements of communion, wore secular clothing during the service, and purged all references to sacrifice from the traditional Mass. He shouted rather than whispered the
words of institution ("This is my body....", etc.) in German instead of Latin, rejected
confession as a prerequisite for communion, and let the communicants take both bread and wine on their own during the
Communion. In January 1522, the Wittenberg city council authorized the removal of imagery from churches and affirmed the changes introduced by Karlstadt on Christmas. Karlstadt wrote his thesis "On the Removal of Images and That There Should Be No Beggars Among Christians" in 1522, shortly after this authorization from the city council. On 19 January Karlstadt married Anna von Mochau, the fifteen-year-old daughter of a poor nobleman. On 20 January the
imperial government and the Pope ordered
Frederick the Wise, Elector of Saxony to undo the changes. Frederick let most of the Mass revert to its Catholic form, but in a letter to the Wittenberg Council, he noted his personal compassion for Karlstadt.
Relationship with Luther In the first week of March, Luther returned from Wartburg. From 9–16 March Luther gave eight sermons in which he stressed some theological similarities with Karlstadt, but, in hindsight, urged caution. This was a major turning point between Karlstadt and Luther. Karlstadt reasserted some of his moderately
mystical leanings, continued wearing peasants' clothing, asked to be called "Brother Andreas," and became disillusioned with academic life, party due to the influence of the
Zwickau Prophets, whose theology stressed an importance on revelation from the
Holy Spirit, rather than scripture. In fact, he renounced his three doctoral degrees, and, according to one source, "gave excellent but infrequent lectures." In May 1523, Karlstadt was invited by the church of
Orlamünde to be its pastor, and he accepted at once. Here he instituted all his radical reforms, and
Orlamünde became the model of a
congregationalist reformation. Church music and art were set aside,
clerical matrimony was preached, and
infant baptism was rejected. Perhaps most importantly, in Orlamünde Karlstadt denied the physical but affirmed the spiritual presence of
Christ in the communion. From Spring 1524, Luther started to campaign against Karlstadt, denying his right to publish and preach without Luther's authorization. In June, Karlstadt resigned as archdeacon. In July, Luther published the
Letter to the Saxon Princes, in which he argued that
Thomas Müntzer and Karlstadt agreed, and were both dangerous sectarians with revolutionary tendencies. Karlstadt defended the observance of the
Sabbath, the seventh day of the week, as a holy day to the Lord. Martin Luther differed from him as he believed that Christians were free to observe any day of the week, provided it was uniform. His defense of the Sabbath, and others among the
Anabaptists, caused him to be censured as a Jew and a heretic. On 22 August 1524, Luther preached in
Jena. Karlstadt hid in the crowd during Luther’s preaching, and wrote to Luther, asking to see him. This led to the well-known confrontation at the Black Bear Inn in a conversation recorded by a Martin Reinhardt and published within a month. There was a number of misunderstandings between the two men. For example, Luther said that he was convinced that Karlstadt had revolutionary tendencies, despite the fact that Karlstadt had all along rejected violence in the name of religion, and rejected
Thomas Müntzer's invitation to join the League of the Elect. Karlstadt's answer was published in 1524 in Wittenberg, and is still extant. This showed that Karlstadt continued to reject the violence that led to the
German Peasants' War. Another defamation was Luther's accusation that Karlstadt was not authorized to preach at the city church in Wittenberg during Luther’s stay at Wartburg. The conversation ended when Luther gave Karlstadt a
guilder and told him to write against him. In September 1524 Karlstadt was exiled from Saxony by
Frederick the Wise and
George, Duke of Saxony. Luther also wrote against Karlstadt in his 1526
The Sacrament of the Body and Blood of Christ—Against the Fanatics.
Peasant War When the Peasant War broke out, Karlstadt was threatened and wrote to Luther and asked for assistance. Luther took him in, and Karlstadt lived secretly in Luther's house for eight weeks. However, Karlstadt had to sign a pseudo retraction, titled "Apology by Dr. Andreas Karlstadt Regarding the False Charge of Insurrection Which has Unjustly Been Made Against Him." It also contained a preface by Luther. In March,
Katharina, Luther's wife, became godmother to one of Karlstadt's children. Karlstadt was not allowed to preach or publish, and supported his family as a farmer and
peddler near Wittenberg until 1529.
Iconoclasm Some of the
Protestant reformers, in particular Andreas Karlstadt, together with
Huldrych Zwingli and
John Calvin encouraged the removal of religious images by invoking the
Decalogue's prohibition of idolatry and the manufacture of graven images of God. As a result, religious statues and images were destroyed and damaged in spontaneous individual attacks as well as unauthorised iconoclastic riots.
Erasmus described in a letter of 1529 such a riot that had occurred in Basel: Karlstadt has been seen as closely associated with
"Bildersturm" (see
Beeldenstorm), as he was at the time. In 1522, he convinced the Council of Wittenberg to order the removal of a number of images from the local churches, which had "catastrophic consequences."
Martin Luther distanced himself from these actions. On 12 March 1522 Karlstadt spoke about Marian pictures, which were venerated at the time, and urged that they all be removed. Special aim was taken at Marian pictures visited in pilgrimages, but he also called for the removal of all public religious imagery and symbols. He asked for the destruction of Marian shrines such as the church Mary the Beautiful in
Regensburg. Karlstadt was supported by
Martin Bucer,
Huldrych Zwingli and
John Calvin. Yet this was more than a local German event. Significant iconoclastic riots took place in
Zürich (in 1523),
Copenhagen (1530),
Münster (1534),
Geneva (1535),
Augsburg (1537), and
Perth (1559). The
Seventeen Provinces (now the
Netherlands and
Belgium and parts of northern France) were hit by a large wave of Protestant iconoclasm in the summer of 1566. In the Netherlands this is called the
"Beeldenstorm" and began with the destruction of all the images of the Monastery of
Saint Lawrence in
Steenvoorde after a
"Hagenpreek" (field sermon) by Sebastiaan Matte, and the sacking of the Monastery of
Saint Anthony after a sermon by Jacob de Buysere. The
"Beeldenstorm" is often held to mark the start of the
Dutch Revolt against the Habsburg rulers of the Netherlands, although the fighting did not begin in earnest for some years.
Death and legacy Fleeing
Saxony, Karlstadt served as a
minister in Switzerland in
Altstätten and
Zürich. In 1534, he went to
Basel as minister of the university church and Professor of Hebrew and Dean of the university. He remained in Basel until he died of the
plague on 24 December 1541. During Karlstadt's lifetime he published about 90 writings in about 213 editions. Between the years 1518–1525, 125 editions of his works were published in
Germany, more than any other writer, save Luther. Karlstadt anticipated many
Anabaptist viewpoints. His books on
the Lord's Supper were published with the co-operation of the Swiss Brethren in Zürich, specifically Felix Mantz and probably Andreas Castelberg, as well as Karlstadt's brother-in-law, Gerhard Westerburg of Cologne, who baptized over 2,000 adults in his swimming pool. Karlstadt's influence on Protestantism in general included the abolition of mandatory celibacy (he married more than three years before Luther, and published several writings on the subject, both in Latin and German). As to images and liturgy, Karlstadt influenced, directly and indirectly, Zwingli, the Anabaptists, the
Presbyterians, the
Congregationalists, the
Baptists and other Protestant groups. He had a remarkable impact on the furrier
Melchior Hoffman, who spread Anabaptist ideas to northern Germany and what is now the Netherlands. == Works ==
