In any account of moderate puritanism, in particular of moderate puritanism in the University of Cambridge, the obvious place to start is Christ's College and the obvious person to start with is Edward Dering. For it was with Dering, a fellow of Christ's College throughout the 1560s, that the foundations of the moderate puritan tradition were laid. Writing of Dering Professor Patrick Collinson has identified, as ‘the obsessive theme’ which ‘necessarily dominates any account of the man’, ‘the intense evangelical experience by a first generation protestant of justification and union with Christ through the renunciation of “will works” and of the world and the exercise of a lively faith’. It was this, together with a ‘consuming desire to convey this experience to others’, that produce Dering's ‘puritanism’. This, as Collinson concluded, ‘should serve as a reminder that much of what we call puritanism at this time was nothing but authentic protestantism and that the reign of Elizabeth was not conspicuously a post-reformation age … but the age of the English reformation par excellence when protestantism was for the first time taking a strong hold on families of the country gentry and the urban middle classes’. The passage is the basic text upon which this study is but an extended commentary.

Certainly Dering himself was well aware that he was living in no post-reformation era; that, in his own words, ‘scarce one of a great many can give an account of their faith’.
