John Strype became involved in interpreting the English Reformation as a result of his complacent Anglicanism, his antiquarian and scholarly interests, and his ambition. The Catholic Nicholas Sander(s) had attacked the English Reformation with, Gilbert Burnet alleged, great scurrility in his De Origine et Progressu Schismatis Anglicani libri tres. Peter Heylyn began to collect materials for a history of the English Reformation and to prepare historical defences for the retention of episcopacy and for the English liturgy. Probably much criticism of Heylyn as an unscrupulous polemicist derives from the fact that his views were so influential. Thomas Fuller's The Church History of Britain was a reply to the various Catholic detailed versions of English Church history since the break with Rome, bore witness to the continued strength of the Foxian apocalyptic vision.
