" We shall conclude this chapter by a melancholy truth, which obtrudes itself on the reluctant mind; that even admitting, without hesitation or inquiry, all that history has recorded, or devotion has feigned, on the subject of martyrdoms, it must still be acknowledged, that the Christians, in the course of their intestine dissensions, have inflicted far greater severities on each other, than they had experienced from the zeal of infidels. During the ages of ignorance which followed the subversion of the Roman empire in the West, the bishops of the Imperial city extended their dominion over the laity as well as clergy of the Latin church. The fabric of superstition which they had erected, and which might long have defied the feeble efforts of reason, was at length assaulted by a crowd of daring fanatics, who from the twelfth to the sixteenth century assumed the popular character of reformers.
