Sooner or later, the Feudal System was certain to result in a period of anarchy. In this country, that period occurred on the death of Henry I., when the feudal party refused to abide by the oaths which the late king had made them swear to his daughter Mathilda. The Peterborough continuation of the English Chronicle describes this period of anarchy "in words with which in their pregnant simplicity no modern description can possibly vie."[117] "They filled the land full of castles, and filled the castles with devils. They took all those that they deemed had any goods, men and women, and tortured them with tortures unspeakable: many thousand they slew with hunger ... and they robbed and burned all the villages so that thou mightest for a day's journey nor ever find a man dwelling in a village nor land tilled. Corn, flesh, and cheese, there was none in the land. The bishops were for ever cursing them but they cared nought therefor.... Men said openly that Christ and His saints slept. Such and more than we can safely say we suffered nineteen years for our sins." Apart from the practical and tangible effects of the Feudal System, medieval theorising on politics brought forward arguments to support the contention that the Church was not only distinct from, but was in certain essential respects superior to, the State. The starting point in such theorising was the dogma of the two powers, the Spiritual and the Temporal, the power of the priesthood derived from the King of Kings, the power of the State derived from the ability to exercise force. Ecclesiastics maintained that of these two powers the greater dignity pertained to the spiritual. This arose directly from the views of the early Church as to the relative importance of the earthly life and of the life to come. To save souls was more important than to regulate physical life; hence, those whose function it was to save souls were not only more worthy of honour than those who simply sought to control temporal activities, but they possessed an authority of a higher and more responsible character. The claim of the Church to a power of inspection and correction in reference to the behaviour and motives of secular rulers enhanced its authority still further. To the sacerdotal mind not only were princes laymen, but of all laymen they were the class most prone to sin and consequently were most in need of clerical censure. Among the duties of the kings which were imperatively insisted upon were "respect for and protection of the Church and her ministers." Hincmar, Gregory VII., and Innocent III. are prominent among those who may be quoted as the protagonists of the claim to ecclesiastical pre-eminence.
