For Luther the Reformation was a watershed because it moved Western Christendom from a long period of captivity under strict papal rule to a new age of freedom. Luther was still a medieval man. Luther extended the notion of church to include every assembly of believers who lived in ‘true faith, hope, and love’. What about those who did not live in that way? ‘Angels and Demons’ explains Luther's views on the threats to the new Christianity and his views on angelic existence. Feeling constantly beset by the devil he was more troubled by that discomfort than he was consoled by the concept of angelic protection.
