Christian Heresies of the
Fifteenth Century:

Hussites:
    The followers of John Huss, the Rector at the University of Prague. He publicly condemned many practices of the Catholic Church. These included the sale of Indulgences and the riches controlled by the Church. Huss had studied the writings of John Wycliffe and supported many of his ideas. The Catholic Church declared over 40 of Wytcliffes Theses as Heretical. Jan Huss however continued to argue that the Church was inherently corrupt and in need of reform. This earned him many admirers and just as many enemies.
    Although it ultimately failed, the Hussite movement is of permanent historical significance. It was the first substantial attack upon the two bulwarks of medieval society, feudalism and the Roman Catholic Church. As such it helped pave the way for both the Protestant Reformation and the rise of modern nationalism.
    After the burning of Huss (1415) and Jerome of Prague (1416), the Hussites continued as a powerful group in Bohemia and Moravia. They drew up (1420) the Four Articles of Prague, demanding freedom of preaching, communion in both kinds (i.e., both wine and bread) for the laity as well as priests, the limitation of property holding by the church, and civil punishment of mortal sin, including simony.

Moravians, "Church of the Brotherhood", United Brethren, after Huss:
    The English priest "Wycliff", denied the authority of the Pope 200 years before Luther. "John Huss", a Bohemian priest (now western Czechoslovakia), followed his ideas... In 1457, some followers of Huss founded the "Church of the Brotherhood", considered the pioneer and the earliest independent Protestant body, even before Luther.
    Later, in 1727, it became the "United Brethren, or Moravian Church". There are now 70,000 in Bethlehem, Nazareth, and Lititz (Pennsylvania, USA), a small number, but their influence has been enormous, the first to light the torch of Protestant missionary zeal.
