These fundamental truths are well illustrated in the following pages. The special period of history chosen, serves to show clearly the real points of dispute. Even Voltaire acknowledged that it was the "wisdom" of Alexander III. that triumphed over the "violence" of Barbarossa. As the same writer observes:--"Alexander revived the rights of the people and suppressed the crimes of Kings." A Pontiff to whom such testimony is borne by Voltaire, cannot fairly be accused of ambitious designs. In his contest with Frederic, from the beginning to the end, he simply asserted the independence of the Church. Antipope after antipope was opposed to him, all of them were puppets of the Emperor; but in the end, even Frederic was obliged to yield, and to acknowledge the patient but determined Alexander as the Vicar of Christ. The subserviency of these pretended Pontiffs is well described by our author. There is no exaggeration here. These men were merely Vicars of the Emperor, existing by his favor, the creatures of his breath. They cared little for the ratification of their decrees in Heaven; so that they knew that they pleased the rulers of this world! What the Emperor wished bound, they did bind, and what he wished loosed, they did loose, even the holy bonds of matrimony. Their degradation and that of the courtier bishops, so graphically depicted in these pages, is a practical proof of the great truth, that while there is no human greatness more exalted than the dignity of the ecclesiastical character, there is no fall lower than that of a churchman who, forgetful of his calling, makes himself the slave of the world's power, be it wielded by a crowned King or by an uncrowned mob. The heartless repudiation of his wife by Henry the Lion, after the mock sentence of the miserable Victor, and the recourse of Constance to Alexander, himself a fugitive, and persecuted, is a touching instance of the manners of the times, and of the protection the Church and her real Pontiffs ever gave to the sanctity of marriage. Little do women in our day think how much they owe to the Popes, who so bravely and so constantly fought their battles in those rude and licentious ages, protecting their innocence, defending their rights, making them the companions, not the servants of those rough warriors. There was more than one Constance in those ages: but never did any of them appeal to the Head of Christendom, that her demand for justice was not heard, and her rights courageously vindicated.
