A series of quotes and extracts from Cardinal Newman's work focussing on the Pope.
Deeply do I feel, ever will I protest, for I can appeal to the ample testimony of history to bear me out, that, in questions of right and wrong, there is nothing really strong in the whole world, nothing decisive and operative, but the voice of him, to whom have been committed the keys of the kingdom and the oversight of Christ’s flock. The voice of Peter is now, as it ever has been, a real authority, infallible when it teaches, prosperous when it commands, ever taking the lead wisely and distinctly in its own province, adding certainty to what is probable, and persuasion to what is certain. Before it speaks, the most saintly may mistake; and after it has spoken, the most gifted must obey.
Peter is no recluse, no abstracted student, no dreamer about the past, no doter upon the dead and gone, no projector of the visionary. Peter for eighteen hundred years has lived in the world; he has seen all fortunes, he has encountered all adversaries, he has shaped himself for all emergencies. If there ever was a power on earth who had an eye for the times, who has confined himself to the practicable, and has been happy in his anticipations, whose words have been deeds, and whose commands prophecies, such is he in the history of ages, who sits from generation to generation in the Chair of the Apostles, as the Vicar of Christ and Doctor of His Church.
It was said by an old philosopher, who declined to reply to an emperor’s arguments, “It is not safe controverting with the master of 20 legions.” What Augustus had in the temporal order, that, and much more, has Peter in the spiritual. When was he ever unequal to the occasion? When has he not risen with the crisis? What dangers have ever daunted him? What sophistry foiled him? What uncertainties misled him? When did ever any power go to war with Peter, material or moral, civilized or savage, and got the better? When did the whole world ever band together against him solitary, and not find him too many for it?
Did the Pope speak against Conscience in the true sense of the word, he would commit a suicidal act. He would be cutting the ground from under his feet. His very mission is to proclaim the moral law, and to protect and strengthen that “Light which enlighteneth every man that cometh into the world.” On the law of conscience and its sacredness are founded both his authority in theory and his power in fact. Whether this or that particular Pope in this bad world always kept this great truth in view in all he did, it is for history to tell. I am considering here the Papacy in its office and its duties, and in reference to those who acknowledge its claims. They are not bound by the Pope’s personal character or private acts, but by his formal teaching. Thus viewing his position, we shall find that it is by the universal sense of right and wrong, the consciousness of transgression, the pangs of guilt, and the dread of retribution, as first principles deeply lodged in the hearts of men, it is thus and only thus, that he has gained his footing in the world and achieved his success. It is his claim to come from the Divine Lawgiver, in order to elicit, protect, and enforce those truths which the Lawgiver has sown in our very nature, it is this and this only that is the explanation of his length of life more than antediluvian. The championship of the Moral Law and of conscience is his raison d’être. The fact of his mission is the answer to the complaints of those who feel the insufficiency of the natural light; and the insufficiency of that light is the justification of his mission.
