If your church is not infallible it is liable to err, for there is no medium between infallibility and liability to error. If your church and her ministers are fallible in their doctrinal teachings, as they admit, they may be preaching falsehood to you, instead of truth. If so, you are in doubt whether you are listening to truth or falsehood. If you are in doubt you can have no faith, for faith excludes doubt, and in that state you displease God, for “without faith it is impossible to please God.”(129) Faith and infallibility must go hand in hand. The one cannot exist without the other. There can be no faith in the hearer unless there is unerring authority in the speaker—an authority founded upon such certain knowledge as precludes the possibility of falling into error on his part, and including such unquestioned veracity as to prevent his deceiving him who accepts his word. You admit infallible certainty in the physical sciences; why should you deny it in the science of salvation? The astronomer can predict with accuracy a hundred years beforehand an eclipse of the sun or moon. He can tell what point in the heavens a planet will reach on a given day. The mariner, guided by his compass, knows, amid the raging storm and the darkness of the night, that he is steering his course directly to the city of his destination; and is not an infallible guide as necessary to conduct you to the city of God in heaven? Is it not, moreover, a blessing and a consolation that, amid the ever-changing views of men, amid the conflict of human opinion and the tumultuous waves of human passion, there is one voice heard above the din and uproar, crying in clear, unerring tones: “Thus saith the Lord?” It is very strange that the Catholic Church must apologize to the world for simply declaring that she speaks the truth, the whole truth, and nothing but the truth. The Roman Pantheon was dedicated to all the gods of the Empire, and their name was legion. Formidable also in numbers are the Founders of the religious sects existing in our country. A Pantheon as vast as Westminster Abbey would hardly be spacious enough to contain life-sized statues for their accommodation. If you were to confront those figures, and to ask them, one by one, to give an account of the faith they had professed, and if they were endowed with the gift of speech, you would find that no two of them were in entire accord, but that they all differed among themselves on some fundamental principle of revelation. Would you not be acting very unwisely and be hazarding your soul’s salvation in submitting to the teachings of so many discordant and conflicting oracles.
