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 the director of Catholic Answers, a lay organisation which explains and defends the beliefs, history and practices of the Catholic Church. He engages in public debates with leading anti-Catholic, and edits Catholic Answers, a monthly journal of apologetics.
