It would leave been very surprising if the Church, menaced as she was by an ever-increasing flood of heresy, had not accepted the State's eager offer of protection. She had always professed a horror for bloodshed. But as long as she was not acting directly, and the State undertook to shed in its own name the blood of wicked men, she began to consider solely the benefits that would accrue to her from the enforcement of the civil laws. Besides, by classing heresy with treason, she herself had laid down the premises of the State's logical conclusion, the death penalty. The Church, therefore, could hardly call in question the justice of the imperial laws, without in a measure going against the principles she herself had advocated. Church and State, therefore, continually influenced one the other. The theology upheld by the Church reacted on the State and caused it to adopt violent measures, while the State in turn compelled the Church to approve its use of force, although such an attitude was opposed to the spirit of early Christianity. The theologians and the canonists put the finishing touches to the situation. Influenced by what was happening around them, their one aim was to defend the laws of their day. This is clearly seen, if we compare the _Summa_ of St. Raymond of Pennafort with the _Summa_ of St. Thomas Aquinas. When St. Raymond wrote his work, the Church still followed the criminal code of Popes Lucius III and Innocent III; she had as yet no notion of inflicting the death penalty for heresy. But in St. Thomas's time, the Inquisition had been enforcing for some years the draconian laws of Frederic II. The Angelic Doctor, therefore, made no attempt to defend the obsolete code of Innocent III, but endeavored to show that the imperial laws, then authorized by the Church, were conformable to the strictest justice. His one argument was to make comparisons, more or less happy, between heresy and crimes against the common law.
