The eighth session of the Council of Constance condemns religious reformers John Wycliffe and John Hus. John Hus had personally appeared before the Council of Constance to propose reforms for the Church.
Rather than listen to him, however, they imprisoned Hus and will put him on trial for heresy within a month of today's condemnation. Eventually he will be sentenced to death by burning at the stake, and his betrayal and execution will inspire further revolt by his followers.
John Hus had brought Wycliffe's ideas to Bohemia, and like Wycliffe, Hus condemned the abuses and corruption in the church. Both Hus and Wycliffe argued that the holy scriptures were superior to any human, including clergy and the pope. This means that anyone who does not strictly obey the Bible — even the pope — should not themselves be obeyed.
Hus had become the head of the University of Prague, giving him with a very powerful and public position for spreading his ideas. He had acquired the support of both his king and many of the people throughout Bohemia. Being excommunicated didn't stop his preaching or his reform efforts; in fact, the excommunication may have made him more famous and popular.
