History testifies of her artful and persistent efforts to insinuate herself into the affairs of nations; and having gained a foothold, to further her own aims, even at the ruin of princes and people. In the year 1204, Pope Innocent III extracted from Peter II, king of Arragon, the following extraordinary oath: “I, Peter, king of Arragonians, profess and promise to be ever faithful and obedient to my lord, Pope Innocent, to his Catholic successors, and the Roman Church, and faithfully to preserve my kingdom in his obedience, defending the Catholic faith, and persecuting heretical pravity.”—John Dowling, The History of Romanism, b. 5, ch. 6, sec. 55. This is in harmony with the claims regarding the power of the Roman pontiff “that it is lawful for him to depose emperors” and “that he can absolve subjects from their allegiance to unrighteous rulers.”—Mosheim, b. 3, cent. 11, pt. 2, ch. 2, sec. 9, note 17.
