In the drama of English church history in the nineteenth century, the reverend Mark Pattison, Rector of Lincoln College, Oxford, from 1861 to 1884, has hitherto been accorded a minor and somewhat transient role. He has appeared in two guises: first, as an Oxford Tractarian who, compelled by Newman’s secession in 1845 to choose between the Church of England and of Rome, opted for the former, but found his faith so unsettled by the process that he eventually lost it altogether; and secondly, as one of the contributors to that landmark—and landmine—of Anglican theology, Essays and Reviews. The argument of this paper is that his role was in fact both more constant and more considerable: an exploration of conflict between learning and religion, reason and faith; a conflict which in one way or another spanned his life, and in which reason did not merely criticise and challenge religion, but also aspired to replace it. In these two forms the conflict of learning and belief was, it need hardly be said, a key element in the so-called ‘Victorian crisis of faith’; insofar as Pattison’s career embodied it, he becomes a representative figure of the experience of his time, and so takes his stand, if not at the centre, then certainly in the foreground of the ecclesiastical stage.
