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.
I strongly advise honest fundamentalists not to read this book. They might find their whole position collapsing in ruins. The fruit of his exhaustive work may be commended most earnestly to all who yearn for the fulfillment of Our Lord's prayer for unity in John 17. A highly readable and accurate presentation of both historical facts and religious truth. Keating gives a solid defense of Catholicism against the critical attacks of fundamentalists, done with patient charity that is bound to convince even the most prejudiced critic of Roman Catholicism.
