This article is the first of three that will evaluate the work and legacy of the Cambridge non-realist theologian and philosopher of religion, Don Cupitt. We begin by suggesting that Cupitt might be depicted as a ‘prophet without honour’ in both his ecclesiastical home of the Church of England and at the University of Cambridge, where he spent most of his professional life. This is based on the observation that, after a promising early career, Cupitt never received the ecclesiastical preferment or academic promotion that many argued he deserved. This arguably represents a missed opportunity for both Church and academy, because Cupitt is more accurately understood not as an enemy of religion but as essentially an ecclesiastical insider whose chief motivation was to uphold the contemporary relevance and credibility of Christianity.
