Readers will not be surprised to find reviewer Whitall N. Perry once more brandishing his ever-sharp critical pen to expose errors in a book on religion. This time, he highlights errors in a book on Pope Pius XII. The book, The Silence of Pius XII, by Carlo Falconi, purports to be an impartial investigation into whether or not Pope Pius XII ignored the atrocities of the Nazis and whether or not he, and the Church, could have done more to stop them. Perry contends that the investigation's results are, in fact, very weighted in the negative, and ignore contrary evidence showing the Pope's efforts on behalf of the persecuted Jews. Perry suggests that the conclusions of Falconi, and others, are probably colored by motives stemming from opposition to traditional Catholicism, and thus to a pope known for his adherence to tradition.
