" The most learned men (I shall not name them) held temporal government for a heathen, human, ungodly thing, as though it were perilous to salvation to be in the ranks of the rulers. Therefore, the priests and monks had so driven kings and princes into the corner, as to persuade them that, to serve God, they must undertake other works, such as hearing mass, saying prayers, endowing masses, etc. In a word, princes and lords who wanted to be pious men held their rank and office as of no value and did not consider it a service of God. They became really priests and monks, except that they did not wear tonsures and cowls. If they would serve God, they must go to church. "
