"Immense," says Guizot, "was the influence which the Christian church exercised over the civilization of modern Europe. In the outset, it was an incalculable advantage to have a moral power, a power destitute of physical force, which reposed only on mental convictions and moral feelings, established amidst that deluge of physical force and selfish violence which overwhelmed society at that period. Had the Christian church not existed, the world would have been delivered over to the influence of physical strength, in its coarsest and most revolting form. It alone exercised a moral power. It did more; it spread abroad the idea of a rule of obedience, a heavenly power, to which all human beings, how great soever, were subjected, and which was above all human laws. That of itself was a safeguard against the greatest evils of society; for it affected the minds of those by whom they were brought about; it professed that belief--the foundation of the salvation of humanity--that there is above all existing institutions, superior to all human laws, a permanent and divine law, sometimes called Reason, sometimes Divine Command, but which, under whatever name it goes, is for ever the same. "Then the church commenced a great work--the separation of the spiritual and temporal power. That separation is the origin of liberty of conscience; it rests on no other principle than that which lies at the bottom of the widest and most extended toleration. The separation of the spiritual and temporal power rests on the principle, that physical force is neither entitled to act, nor can ever have any lasting influence, on thoughts, conviction, truth; it flows from the eternal distinction between the world of thought and the world of action, the world of interior conviction and that of external facts. In truth, that principle of the liberty of conscience, for which Europe has combated and suffered so much, which has so slowly triumphed, and often against the utmost efforts of the clergy themselves, was first founded by the doctrine of the separation of the temporal and spiritual power, in the cradle of European civilization. It is the Christian church which, by the necessities of its situation to defend itself against the assaults of barbarism, introduced and maintained it. The presence of a moral influence, the maintenance of a Divine law, the separation of the temporal and spiritual power, are the three great blessings which the Christian church has diffused in the dark ages over European society.
