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 them into three individual volumes containing 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 succinct style of their answers, plus the prodigious learning these men display. Containing over 1500 questions and answers on every aspect of the Catholic faith they are fully indexed, and readily serve as a wonderful source of reference.
