Romanism is now regarded by Protestants with far greater favor than in former years. In those countries where Catholicism is not in the ascendancy, and the papists are taking a conciliatory course in order to gain influence, there is an increasing indifference concerning the doctrines that separate the reformed churches from the papal hierarchy; the opinion is gaining ground that, after all, we do not differ so widely upon vital points as has been supposed, and that a little concession on our part will bring us into a better understanding with Rome. The time was when Protestants placed a high value upon the liberty of conscience which had been so dearly purchased. They taught their children to abhor popery and held that to seek harmony with Rome would be disloyalty to God. But how widely different are the sentiments now expressed!
The defenders of the papacy declare that the church has been maligned, and the Protestant world are inclined to accept the statement. Many urge that it is unjust to judge the church of today by the abominations and absurdities that marked her reign during the centuries of ignorance and darkness. They excuse her horrible cruelty as the result of the barbarism of the times and plead that the influence of modern civilization has changed her sentiments.
Have these persons forgotten the claim of infallibility put forth for eight hundred years by this haughty power? So far from being relinquished, this claim was affirmed in the nineteenth century with greater positiveness than ever before. As Rome asserts that the “church never erred; nor will it, according to the Scriptures, ever err” (John L. von Mosheim, Institutes of Ecclesiastical History, book 3, century II, part 2, chapter 2, section 9, note 17), how can she renounce the principles which governed her course in past ages?
The papal church will never relinquish her claim to infallibility. All that she has done in her persecution of those who reject her dogmas she holds to be right; and would she not repeat the same acts, should the opportunity be presented? Let the restraints now imposed by secular governments be removed and Rome be reinstated in her former power, and there would speedily be a revival of her tyranny and persecution.
A well-known writer speaks thus of the attitude of the papal hierarchy as regards freedom of conscience, and of the perils which especially threaten the United States from the success of her policy:
“There are many who are disposed to attribute any fear of Roman Catholicism in the United States to bigotry or childishness. Such see nothing in the character and attitude of Romanism that is hostile to our free institutions, or find nothing portentous in its growth. Let us, then, first compare some of the fundamental principles of our government with those of the Catholic Church.
“The Constitution of the United States guarantees liberty of conscience. Nothing is dearer or more fundamental. Pope Pius IX, in his Encyclical Letter of August 15, 1854, said: `The absurd and erroneous doctrines or ravings in defense of liberty of conscience are a most pestilential error—a pest, of all others, most to be dreaded in a state.’ The same pope, in his Encyclical Letter of December 8, 1864, anathematized `those who assert the liberty of conscience and of religious  worship,’ also ‘all such as maintain that the church may not employ force.’
“The pacific tone of Rome in the United States does not imply a change of heart. She is tolerant where she is helpless. Says Bishop O’Connor: ‘Religious liberty is merely endured until the opposite can be carried into effect without peril to the Catholic world.’. . . The archbishop of St. Louis once said: ‘Heresy and unbelief are crimes; and in Christian countries, as in Italy and Spain, for instance, where all the people are Catholics, and where the Catholic religion is an essential part of the law of the land, they are punished as other crimes’…
