The Human Mystery of Sexuality is the book which recently came into the public eye when it called upon Father Oraison's head the displeasure of what was at that time. the Holy Office. From this end, it is difficult to see what all the fuss was about. The author is a psychiatric counselor and a priest, and exercising his professional competence in both fields he has outlined a method of integrating psychological and scriptural approaches to psycho-sexual development. His treatment is wholly non-sensational, and is characterized by that professional caution which is the professional virtue of both priest and psychiatrist.
