In the same year in which the above-mentioned Bulgarian tyrant reigned and instituted so much wickedness against the Christian believers, namely, A. D. 842, the kings of the Franks, through their wars, though they were brothers, it appears, grievously persecuted and martyred the poor believers, everywhere in the French territories; so that said persecution and martyrdom is compared and regarded as equal to the persecutions instituted in earlier times by the heathen emperors. Of this, the following is found in the last-mentioned chronicle, and in the same place, "The fraternal wars between the kings of the Franks, were the cause of much calamity and distress to the poor believers throughout France, so that they might well be compared to the cruel persecutions which in former times occurred under the heathen princes."
Concerning this, Remigius, bishop of Auxerre, who lived about this time, writes thus (on Ps. 69), "There are different times of persecution; one, when the heathen fall unmercifully upon the Christians; the other, when the evil purpose of the (false) Christians persecutes the believers, which time still continues in the church; for, though the heathen kings, and others, are dead, still the devil is not dead, who secretly vents his cruelty, by secret instruments, that is, through bad Christians.
