Caspar (or Kaspar) Schwen(c)kfeld von Ossig ( listen (help·info)) (1489 or 1490 – 10 December 1561) was a German theologian, writer, and preacher who became a Protestant Reformer and spiritualist, one of the earliest promoters of the Protestant Reformation in Silesia.
Schwenckfeld came to Reformation principles through Thomas Müntzer and Andreas Karlstadt. However, he developed his own principles and fell out with Martin Luther over the eucharistic controversy (1524). He had his own views on the sacraments - the Heavenly Flesh doctrine - developed in close association with his humanist colleague, Valentin Crautwald (1465–1545). His followers became a new sect, which was outlawed in Germany, but his ideas influenced Anabaptism, Pietism on mainland Europe, and Puritanism in England.
Schwenckfeld was born in Ossig near Liegnitz, Silesia now Osiek, near Legnica, Poland, to noble parents in 1489. From 1505 to 1507 he was a student in Cologne, and in 1507 enrolled at the University of Frankfurt on the Oder. Between 1511 and 1523, Schwenckfeld served the Duchy of Liegnitz as an adviser to Duke Charles I (1511–1515), Duke George I (1515–1518), and Duke Frederick II (1518–1523).
From Catholic to Reformer to Radical Reformer
In 1518 or 1519, Schwenckfeld experienced an awakening that he called a "visitation of God." Luther's writings had a deep influence on Schwenckfeld, and he embraced the "Lutheran" Reformation and became a student of the Scriptures. In 1521, Schwenckfeld began to preach the gospel, and in 1522 won Duke Friedrich II over to Protestantism. He organized a Brotherhood of his converts for the purpose of study and prayer in 1523. In 1525, he rejected Luther's idea of Real Presence and came to a spiritual interpretation of the Lord's Supper, which was subsequently rejected by Luther. Schwenckfeld began to teach that the true believer ate the spiritual body of Christ. He pushed for reformation wherever he went, but also criticized reformers that he thought went to extremes. He emphasized that for one to be a true Christian, one must not change only outwardly but inwardly. Because of the communion and other controversies, Schwenckfeld broke with Luther and followed what some describe as a "middle way". Because of his break from Luther and the Magisterial Reformation, scholars typically categorize Schwenckfeld as a member of the Radical Reformation. He voluntarily exiled himself from Silesia in 1529 in order to relieve pressure on and embarrassment of his duke. He lived in Strassburg from 1529–1534 and then in Swabia.
Some of the teachings of Schwenckfeld included opposition to war, secret societies, and oath-taking, that the government had no right to command one's conscience, that regeneration is by grace through inner work of the Spirit, that believers feed on Christ spiritually, and that believers must give evidence of regeneration. He rejected infant baptism, outward church forms, and "denominations". His views on the Eucharist prompted Luther to publish several sermons on the subject in his 1526 The Sacrament of the Body and Blood of Christ—Against the Fanatics.
In 1540 Martin Luther expelled Caspar Schwenckfeld from Silesia. In 1541, Schwenckfeld published the Great Confession on the Glory of Christ. Many considered the writing to be heretical. He taught that Christ had two natures, divine and human, but that he became progressively more divine. He also published a number of works about interpreting the Scriptures during the 1550s, often responding to the rebuttals of the Lutheran Reformer Matthias Flacius Illyricus.
In 1561, Schwenckfeld became sick with dysentery, and gradually grew weaker until he died in Ulm on the morning of December 10, 1561. Because of his enemies, the fact of his death and the place of his burial were kept secret.
Schwenckfeld did not organize a separate church during his lifetime, but followers seemed to gather around his writings and sermons. In 1700 there were about 1,500 of them in Lower Silesia. Many fled Silesia under persecution of the Austrian emperor, and some found refuge on the lands of Count Nicolaus Ludwig Zinzendorf. These followers became known as Schwenkfelders. A group arrived in Philadelphia in 1731, followed by five more migrations up to 1737. In 1782, the Society of Schwenkfelders was formed, and in 1909 the Schwenkfelder Church was organized.
The Schwenkfelder Church has remained small, and currently there are five churches with about 3,000 members in southeastern Pennsylvania. All of these bodies are within a fifty-mile radius of Philadelphia.
Schwenkfelder Library & Heritage Center
The Schwenkfelder Library & Heritage Center is a small museum, library and archives in Pennsburg, Pennsylvania. It is the only institution dedicated to the preservation and interpretation of the Schwenkfelder story, including Caspar Schwenckfeld, the Radical Reformation, religious toleration, the Schwenkfelders in Europe and America, and the Schwenkfelder Church. The Schwenkfelder Library & Heritage Center has exhibits and programs throughout the year.
