This text began in the 1860s as a phrase from Matthew Arnold's picture of the decline of religion as the retreat of the tide on Dover's beach. The book has had a significant impact, for its account of historical developments and its presentation of Christian non-realism.

The Sea of Faith made a huge impact when it was first published to accompany a major television series in the mid 1980's. For a generation that was embodying the ebbing of the tide of faith, it articulated the huge intellectual and cultural shifts that had resulted in most people no longer having any connection with official religion. For many who, whilst still going to church, glimpsed horizons wider than those offered by traditional forms of religious thought, The Sea of Faith offered liberating freedom, encouraging them to have minds of their own in matters of faith. For many more who had abandoned the church, it once again made the wider question a matter of serious and worthwhile concern. Today, the Sea of Faith networks exist in Britain, Australia and New Zealand and the movement is known around much of the world. The Sea of Faith is rightly acknowledged as one of the most influential theological texts of recent years. With a preface by George Pattison
