Diogenes Allen’s new book . . . begins with an autobiographical exploration as to his discovery of ‘spiritual theology’ after years of being ‘a teacher of philosophy and theology to students preparing to be ministers.’“This introduction is helpful and sets the scene for Allen’s endeavour, which is to open up the depths and vistas of the Great Tradition as a practice of holy living—a bodily practice of learning ‘to live every moment of one’s life with an awareness of God.’ Allen writes fluently, and in eleven shortish chapters covers the classical pattern of the spiritual journey as it has been repeatedly performed in the tradition. Above all his work bears the very real enthusiasm of a ‘convert’ who you sense is discovering something for the first time and is exceptionally eager to pass it on.
