*Canon law considered incorrect or false judgement to be error when such a judgement was not based upon ignorance. Such an error might be opinions or judgements made by Lollards or more specifically John Wyclif.
Among the errors attributed to Wyclif were the following: that it was against Holy Writ for clerics to have temporal property; that it was lawful for anyone to preach, even though they were neither deacon nor priest; that a *friar who begged after giving a sermon was simoniacal. -
