Martin Bucer (; Early German: ; 11 November 1491 – 28 February 1551) was an Alsatian Protestant reformer based in Strasbourg who influenced Lutheran and Anglican doctrines and practices as well as Reformed theology. Bucer was originally a member of the Dominican Order, but after meeting and being influenced by Martin Luther in 1518 he arranged for his monastic vows to be annulled. He then began to work for the Reformation, with the support of Franz von Sickingen.
Bucer's efforts to reform the church in Wissembourg resulted in his excommunication from the Catholic Church, and he was forced to flee to Strasbourg. There he joined a team of reformers which included Matthew Zell, Wolfgang Capito, and Caspar Hedio. He acted as a mediator between the two leading reformers, Martin Luther and Huldrych Zwingli, who differed on the doctrine of the Eucharist. Later, Bucer sought agreement on common articles of faith such as the Tetrapolitan Confession and the Wittenberg Concord, working closely with Philipp Melanchthon on the latter.
Bucer believed that the Catholics in the Holy Roman Empire could be convinced to join the Reformation. Through a series of conferences organised by Charles V, he tried to unite Protestants and Catholics to create a German national church separate from Rome. He did not achieve this, as political events led to the Schmalkaldic War and the retreat of Protestantism within the Empire. In 1548, Bucer was persuaded, under duress, to sign the Augsburg Interim, which imposed certain forms of Catholic worship. However, he continued to promote reforms until the city of Strasbourg accepted the Interim, and forced him to leave.
In 1549, Bucer was exiled to England, where, under the guidance of Thomas Cranmer, he was able to influence both Edwardine Ordinals and the second revision of the Book of Common Prayer. He died in Cambridge, England, at the age of 59. Although his ministry did not lead to the formation of a new denomination, many Protestant denominations have claimed him as one of their own. He is remembered as an early pioneer of ecumenism.
Historical context
In the 16th century, the Holy Roman Empire was divided into many princely and city states that provided a powerful check on the rule of the Holy Roman Emperor. The division of power between the emperor and the various states made the Reformation in Germany possible, as individual states defended reformers within their territories. In the Electorate of Saxony, Martin Luther was supported by the elector Frederick III and his successors John and John Frederick. Philip I, Landgrave of Hesse—whose lands lay midway between Saxony and the Rhine—also supported the Reformation, and he figured prominently in the lives of both Luther and Bucer. The Emperor Charles V was often distracted by war with France and the Ottoman Empire and in Italy. The political rivalry among all the players greatly influenced the ecclesiastical developments within the Empire.
In addition to the princely states, free imperial cities, nominally under the control of the Emperor but really ruled by councils that acted like sovereign governments, were scattered throughout the Empire. As the Reformation took root, clashes broke out in many cities between local reformers and conservative city magistrates. It was in a free imperial city, Strasbourg, that Martin Bucer began his work. Located on the western frontier of the Empire, Strasbourg was closely allied with the Swiss cities that had thrown off the imperial yoke. Some had adopted a reformed religion distinct from Lutheranism, in which humanist social concepts and the communal ethic played a greater role. Along with a group of free imperial cities in the south and west of the German lands, Strasbourg followed this pattern of Reformation. It was ruled by a complex local government largely under the control of a few powerful families and wealthy guildsmen. In Bucer's time, social unrest was growing as lower-level artisans resented their social immobility and the widening income gap. The citizens may not have planned revolution, but they were receptive to new ideas that might transform their lives.
Early years (1491–1523) Martin Bucer was born in Sélestat (Schlettstadt), Alsace, a free imperial city of the Holy Roman Empire. His father and grandfather, both named Claus Butzer, were coopers (barrelmakers) by trade. Almost nothing is known about Bucer's mother. Bucer likely attended Sélestat's prestigious Latin school, where artisans sent their children. He completed his studies in the summer of 1507 and joined the Dominican Order as a novice. Bucer later claimed his grandfather had forced him into the order. After a year, he was consecrated as an acolyte in the Strasbourg church of the Williamites, and he took his vows as a full Dominican friar. In 1510, he was ordained as a deacon.
By 1515, Bucer was studying theology in the Dominican monastery in Heidelberg. The following year, he took a course in dogmatics in Mainz, where he was ordained a priest, returning to Heidelberg in January 1517 to enroll in the university. Around this time, he became influenced by humanism, and he started buying books published by Johannes Froben, some by the great humanist Erasmus. A 1518 inventory of Bucer's books includes the major works of Thomas Aquinas, leader of medieval scholasticism in the Dominican Order.
In April 1518, Johannes von Staupitz, the vicar-general of the Augustinians, invited the Wittenberg reformer Martin Luther to argue his theology at the Heidelberg Disputation. Here Bucer met Luther for the first time. In a long letter to his mentor, Beatus Rhenanus, Bucer recounted what he learned, and he commented on several of Luther's Ninety-five Theses. He largely agreed with them and perceived the ideas of Luther and Erasmus to be in concordance. Because meeting Luther posed certain risks, he asked Rhenanus to ensure his letter did not fall into the wrong hands. He also wrote his will, which contains the inventory of his books. In early 1519, Bucer received the baccalaureus degree, and that summer he stated his theological views in a disputation before the faculty at Heidelberg, revealing his break with Aquinas and scholasticism.
The events that caused Bucer to leave the Dominican Order arose from his embrace of new ideas and his growing contact with other humanists and reformers. A fellow Dominican, Jacob van Hoogstraaten, the Grand Inquisitor of Cologne, tried to prosecute Johann Reuchlin, a humanist scholar. Other humanists, including the nobles Ulrich von Hutten and Imperial Knight Franz von Sickingen, took Reuchlin's side. Hoogstraten was thwarted, but he now planned to target Bucer. On 11 November 1520, Bucer told the reformer Wolfgang Capito in a letter that Hoogstraaten was threatening to make an example of him as a follower of Luther. To escape Dominican jurisdiction, Bucer needed to be freed of his monastic vows. Capito and others were able to expedite the annulment of his vows, and on 29 April 1521 he was formally released from the Dominican Order.
For the next two years, Bucer was protected by Sickingen and Hutten. He also worked for a time at the court of Ludwig V, Elector Palatine, as chaplain to Ludwig's younger brother Frederick. Sickingen was a senior figure at Ludwig's court. This appointment enabled Bucer to live in Nuremberg, the most powerful city of the Empire, whose governing officials were strongly reformist. There he met many people who shared his viewpoint, including the humanist Willibald Pirckheimer and the future Nuremberg reformer Andreas Osiander. In September 1521, Bucer accepted Sickingen's offer of the position of pastor at Landstuhl, where Sickingen had a castle, and Bucer moved to the town in May 1522.; In summer 1522, he met and married Elisabeth Silbereisen, a former nun.
Sickingen also offered to pay for Bucer to study in Wittenberg. On his way, Bucer stopped in the town of Wissembourg, whose leading reformer, Heinrich Motherer, asked him to become his chaplain. Bucer agreed to interrupt his journey and went to work immediately, preaching daily sermons in which he attacked traditional church practices and monastic orders. On the basis of his belief that the Bible was the sole source for knowledge to attain salvation (), he preached that the Mass should not be considered as the recrucifying of Christ, but rather the reception of God's gift of salvation through Christ. He accused the monks of creating additional rules above what is contained in the Bible. He summarised his convictions in six theses, and called for a public disputation. His opponents, the local Franciscans and Dominicans, ignored him, but his sermons incited the townspeople to threaten the town's monasteries. The bishop of Speyer reacted by excommunicating Bucer, and although the town council continued to support him, events beyond Wissembourg left Bucer in danger. His leading benefactor, Franz von Sickingen, was defeated and killed during the Knights' War, and Ulrich von Hutten became a fugitive. The Wissembourg council urged Bucer and Motherer to leave, and on 13 May 1523 they fled to nearby Strasbourg.
Reformer in Strasbourg (1523–1525) Bucer, excommunicated and without means of subsistence, was in a precarious situation when he arrived in Strasbourg. He was not a citizen of the city, a status that afforded protection, and on 9 June 1523 he wrote an urgent letter to the Zürich reformer, Huldrych Zwingli, pleading for a safe post in Switzerland. Fortunately for Bucer, the Strasbourg council was under the influence of the reformer, Matthew Zell; during Bucer's first few months in the city he worked as Zell's unofficial chaplain and was able to give classes on books of the Bible. The largest guild in Strasbourg, the or Gardeners, appointed him as the pastor of St Aurelia's Church on 24 August 1523. A month later the council accepted his application for citizenship.
In Strasbourg, Bucer joined a team of notable reformers: Zell, who took the role of the preacher to the masses; Wolfgang Capito, the most influential theologian in the city; and Caspar Hedio, the cathedral preacher. One of Bucer's first actions in the cause of reform was to debate with Thomas Murner, a monk who had attacked Luther in satires. While the city council vacillated on religious issues, the number of people supporting the Reformation and hostile towards the traditional clergy had grown.
The hostility reached a boiling point when Conrad Treger, the prior provincial of the Augustinians, denounced the reformist preachers and the burghers of Strasbourg as heretics. On 5 September 1524, angry mobs broke into the monasteries, looting and destroying religious images. Many opponents of the Reformation were arrested, including Treger. After the council requested an official statement from the reformers, Bucer drafted twelve articles summarising the teachings of the Reformation, including justification by faith (). He rejected the Mass and Catholic concepts such as monastic vows, veneration of saints, and purgatory. He refused to recognise the authority of the pope and instead emphasised obedience to the government. Treger was released on 12 October and left Strasbourg. With his departure, overt opposition to the Reformation ended in the city.
