John Wycliffe

====''De officio regis''====
The attacks on Pope Gregory XI grew ever more extreme. Wycliffe's stand concerning the ideal of poverty became continually firmer, as well as his position with regard to the temporal rule of the clergy. Closely related to this attitude was his book ''De officio regis'', the content of which was foreshadowed in his 33 conclusions. This book, like those that preceded and followed, was concerned with the reform of the Church, in which the temporal arm was to have an influential part.

From 1380 onwards, Wycliffe devoted himself to writings that argued his rejection of [[transubstantiation]], and strongly criticised the [[friars]] who supported it.<ref name="hudson">{{ cite book |last=Hudson |first=Anne |url=https://archive.org/details/prematurereforma0000huds |title=The premature Reformation: Wycliffite texts and Lollard history |date=2002 |publisher=Clarendon |isbn=978-0-19-822762-5 |location=Oxford |author-link=Anne Hudson (academic) |url-access=registration }}</ref>{{Rp|281}}
