Fr Bouyer is never superficial, but it is a pity that his profound thought should not be expressed with more clarity and economy. This is particularly true of'an essay on the place of the Virgin Mary in Christian theology and its significance for humanity,' since a subject of such maystery and delicacy suffers in its impact on the reader from a very analytical and somewhat heavy and repetitive treatment. Nevertheless the basic thought of this book is of great value, particularly at this time when much attention is necessarily given to the subject of sexuality. Fr Bouyer faces questions which arise in many minds and, in the light of the scriptural exegesis of the early church and of the gospel account of the place of our Lady in the work of redemption, he strives to provide answers on the subjects of sex, virginity, marriage and the family as seen in the light of revelation.
