For many, the best way to reach an understanding of the Catholic Church is to see how other people misunderstand it. This book is full of misunderstandings.The people quoted in these pages came to their confusions in various ways. Sometimes it was by reading the wrong books or by failing to read the right books. Sometimes it was a matter of heredity, with prejudices passed down from father to son and from mother to daughter. At other times errors were imbibed at the foot of the pulpit, in the university lecture hail, or from door-to-door missionaries.Whatever their origin, misunderstandings are misunderstandings. They should be recognized for what they are and set aside, even if that means a break from personal habit or family tradition. More than a century ago, Pope Leo XIII noted that there is nothing so salutary as to understand the world as it really is. That is true particularly of the Church that Christ established because to misunderstand her is to misunderstand him.
