Karl Keating defends Catholicism from fundamentalist attacks and explains why fundamentalism has been so successful in converting Romanists. After showing the origins of fundamentalism, he examines representative anti-Catholic groups and presents their arguments in their own words. His rebuttals are clear, detailed, and charitable. Special emphasis is given to the scriptural basis for Catholic doctrines and beliefs.

"Karl Keating is simply one of the best Catholic apologists alive. He writes in the tradition of, and as a worthy successor to, Fred Sheed and Archbishop Fulton Sheen. He is thoroughly orthodox, reasonable, clear, and interesting"....Ralph McInermy
