MY DEAR READER:-Perhaps this is the first time in your life that you have handled a book in which the doctrines of the Catholic Church are expounded by one of her own sons. You have, no doubt, heard and read many things regarding our Church; but has not your information come from teachers justly liable to suspicion? You asked for bread, and they gave you a stone. You asked for fish, and they reached you a serpent. Instead of the bread of truth, they extended to you the serpent of falsehood. Hence, without intending to be unjust, is not your mind biased against us because you listened to false witnesses? This, at least, is the case with thousands of my countrymen whom I have met in the brief course of my missionary career. The Catholic Church is persistently misrepresented by the most powerful vehicles of information.
