Czech religious reformer Jan Hus (1369-1415) read the Bible to his congregations in their native language, whereas the Catholic Church demanded that the Bible only be read in Latin. Also, the practice of the church at the time was that during communion, the chalice was reserved for the clergy, the laity only receiving bread. When a church council condemned the practice of some priests who were giving the chalice to their congregants, Hus refused to support the condemnation. After his execution by burning in 1415, Hus' followers adopted the "lay chalice" as an important symbol of their movement.
