 Most of the English clergy were irritated by this encounter, and attacks upon Wycliffe began.The second and third books of his work dealing with civil government carry a sharp polemic.On 22 May 1377 Pope Gregory XI sent five copies of a bull against Wycliffe, dispatching one to the Archbishop of Canterbury, and the others to the Bishop of London, King Edward III, the Chancellor, and the university; among the enclosures were 18 theses of his, which were denounced as erroneous and dangerous to Church and State.
