On those little sentences have been built up the mighty edifice of the Church of Rome; in them lie the authority for the imperial power of the Popes over temporal affairs, and their godlike power to curse a soul or wash it white from sin. To sustain the position of “the only true Church,” which Rome claims was thus conferred upon her, she has fought and labored and struggled for many a century, and will continue to keep herself busy in the same work to the end of time. The memorable words I have quoted give to this ruined city about all the interest it possesses to people of the present day.
