“Radio Replies” are questions and answers about the Catholic faith compiled and published by the famous radio priests Fathers Rumble and Carty. Father Rumble broadcast from Sydney, Australia, and Father Carty from St. Paul, Minnesota. The questions printed here were sent in by the many listeners of these intrepid priests, who answered them over the air. Later, they assembled into these three volumes their best questions and answers about the Catholic faith. That work now comprises a unique body of apologetics. The immense popularity of these books is due in no small part to the direct and succint style of their answers, plus the prodigious learning these men display. Containing some 4,374 questions and answers, these books provide hours of stimulating, informative reading on virtually every subject relating to the Church, and being fully indexed, they readily serve as a wonderful source of reference about the Faith. Further, these writings, like none other, impart an immediacy and a crusading spirit, which convey to the reader a warmth and a love and a zeal for our holy religion.
