The followers of the Silesian Reformation theologian Caspar Schwenckfeld (1490–1561). Schwenckfeld, who was a mystic by temperament, was impressed by the writings of J. Tauler and M. Luther, but soon found that he could not give unreserved assent to many of the Protestant doctrines. He also came to hold a doctrine of the deification of Christ's humanity, and in 1540 he issued an account of his beliefs on this subject. A few years later he withdrew from the Lutheran Church. After his death a small band of disciples, calling themselves the ‘Confessors of the Glory of Christ’, continued to propagate his teaching. A branch, established in Philadelphia in 1734, survives.
