7 Again, if We consider the achievements of the see of Rome, what can be more wicked than to deny how much and how well the Roman bishops have served civilized society at large? For Our predecessors, to provide for the peoples' good, encountered struggles of every kind, endured to the utmost burdensome toils, and never hesitated to expose themselves to most dangerous trials. With eyes fixed on heaven, they neither bowed down their head before the threats of the wicked, nor allowed themselves to be led by flattery or bribes into unworthy compliance. This apostolic chair it was that gathered and held together the crumbling remains of the old order of things; this was the kindly light by whose help the culture of Christian times shone far and wide; this was an anchor or safety in the fierce storms by which the human race has been convulsed; this was the sacred bond of union that linked together nations distant in region and differing in character; in short, this was a common center from which was sought instruction in faith and religion, no less than guidance and advice for the maintenance of peace and the functions of practical life. In very truth it is the glory of the supreme Pontiffs that they steadfastly set themselves up as a wall and a bulwark to save human society from falling back into its former superstition and barbarism.
