Father Capon (Episcopal) has this going for him -- he is one of the most graceful and entertaining writers on the religious scene today. He amuses, delights, and astonishes. And when the last page has been read, these things remain -- but nothing more. His present work, on images and mystery in Christian faith, is like Supper of the Lamb (1970), a theological delicacy which leaves the soul empty. These ""excursions, into the fearful and wonderful world of what Christian revelation has to say about God"" are restatements, in elegant rhetoric, of what the Church, at least in its Protestant manifestations, has always taught on matters such as the Bible, the Incarnation, the priesthood, the soul -- and sixteen other subjects which, despite the piquancy of the titles, are predictable. This is not to say that Hunting the Divine Fox is not an exciting, articulate little book. It is that, and more. But one questions whether what Christians really need from a man of Father Capon's talents is merely entertainment.
