This is William Johnston's summary of the message of The Cloud of Unknowing. Nobody knows who wrote the book, or exactly where he lived, or whether he was a member of a religious order, or even, really, whether he was part of any church at all. The text first appeared in Middle English in the 14th century, and it has inspired generations of mystical searchers (from St. John of the Cross to Teilhard de Chardin). The mysterious conditions of its composition, however, focus the reader's attention squarely on the book's message--an almost Zen rendering of Christianity, which has a great deal to teach our querulous, doctrine-obsessed churches: "And so I urge you," the author writes, "go after experience rather than knowledge. On account of pride, knowledge may often deceive you, but this gentle, loving affection will not deceive you. Knowledge tends to breed conceit, but love builds. Knowledge is full of labor, but love, full of rest." --Michael Joseph Gross
