Jаn Hus, Letter tо the Supreme Cоurt оf the Kingdom of Bohemiа, (1411?) ...I аm indeed aware that I refuse to obey either Pope or Archbishop when they forbid my preaching, for to cease preaching would be contrary to the will of God and my salvation. But I know, beloved lords, that even you do not obey the command which the late Pope gave in the bull which was bought by them at a great price. . . What is Hus talking about in his letter?
