Forty years ago the story of the Church in late medieval England was a simple one and not very different from the version which had prevailed half a century before that. The interpretation presented by W. Capes in 1900 had been slightly modified but largely underlined by 1950, and the Church and its development which was commonly depicted in that year would not have been strikingly unfamiliar to him. The current version was that, after the reforming efforts of the thirteenth century, which failed to achieve their end, and the advent of the friars, who even by the middle of that century were departing from their earlier zeal and purity, the Church in the following hundred years was exploited by the pope when it was not saved or oppressed by the Crown. The resulting corruption of the clergy contributed to its negligence and provoked an eruption of heresy which in due course was savagely suppressed and virtually expunged; rid of this threat, the fifteenth-century clergy were so notorious for their laxity, greed and mediocrity that a few devout members of the laity, perhaps inspired by the mystical writings, took refuge in private devotions which anticipated the individualism of the Protestant. The Reformation was viewed as the inescapable result of these circumstances.
