At the beginning of 1409 Wenceslaus tried to get Prague University to add its support to the French proposal for resolving the papal schism, which he himself supported. His effort, however, were thwarted by the opposition of the German masters, which led him to issue the Kutná Hora Decree on 18 January.

In 1410, the Archbishop ordered Wyclif´s book to be burned. Hus protested againts this from the pulpit and, as a consequence, was anathematized by the Archbishop. The archbishop then brought a complaint against Hus before the new pope, John XXIII, and Hus was summoned to appear before the papal court.

In 1412, papal emissaries arrived in the city with a papal bull authorizing them to sell indulgences. On the 7 June, Hus spoke our againts this simony in public disputation.

Prague was placed under interdict (no church offices, including baptisms, funeral, masses, were allowe to be held in the city while Hus remained there). Hus therefore left Prague in November.

During his stay in the countryside Hus preached in the Czech language to the ordinary people and laso produced a number of writing. In 1412 he wrote The Creed, the Ten Commandments and the Paternoster etc., in 1414 The essence of Christian teaching. In the winter 1412/1413 he produced the important Latin tract De ecclesia (Concerning the church) which summarizes his teachings.
