In 1415, three decades after Wycliffe’s death, the Council of Constance declared him a heretic. It decreed that copies of his writings be destroyed and his remains removed from consecrated ground. The latter order wasn’t carried out until 1428, when Wycliffe’s body was exhumed and burned. Many of his followers weren’t so lucky and were burned alive, including the Bohemian preacher Jan Hus at Constance.
Wouldn't it have been more effective to punish him while he was alive?
It seems a little late that the Chruch condemed Wycliffe after his death. It is even more unfair to punish someone for following his beliefs 30 years after his death.
It would be akin to punishing someone born in the 1990's for believing in something already baked into the culture.
