The strange phenomenon of a Catholic candidate for the presidency being required to be put to a test of his loyalty by some of the people-in direct contradiction to the intention of the Founding Fathers of the United States- is here reviewed in historical detail. Though a Catholic President is in the White House, the issue is not dead. Some might want to forget what happened in the last campaign as well as in other campaigns of the past but our system of government could not be served by doing so. The authors argue that a study such as this is needed to see the broader implications of what was involved and what might follow. The book is, therefore, a history of the religious issue reviewed in terms of anti-Catholicism. The sources used are extensive and responsible and do represent all sides of the question. While bigotry is the book's subject, the authors are objective in their evaluations. This is indeed a timely analysis of a hotly debated area of human relationships peculiar to a ""society of incompatible faiths"".
