Zeal for religion was not the motive which inspired the chief authors of this extraordinary crime. They were trained to look on the safety of the monarchy as the sovereign law, and on the throne as an idol that justified sins committed in its worship. At all times there have been men, resolute and relentless in the pursuit of their aims, whose ardour was too strong to be restricted by moral barriers or the instinct of humanity. In the sixteenth century, beside the fanaticism of freedom, there was an abject idolatry of power; and laws both human and divine were made to yield to the intoxication of authority and the reign of will. It was laid down that kings have the right of disposing of the lives of their subjects, and may dispense with the forms of justice. The Church herself, whose supreme pontiff was now an absolute monarch, was infected with this superstition. Catholic writers found an opportune argument for their religion in the assertion that it makes the prince master of the consciences as well as the bodies of the people, and enjoins submission even to the vilest tyranny.[75] Men whose lives were precious to the Catholic cause could be murdered by royal command, without protest from Rome. When the Duke of Guise, with the Cardinal his brother, was slain by Henry III., he was the most powerful and devoted upholder of Catholicism in France. Sixtus V. thundered against the sacrilegious tyrant who was stained with the blood of a prince of the Church; but he let it be known very distinctly that the death of the Duke caused him little concern.[76] Catherine was the daughter of that Medici to whom Machiavelli had dedicated his _Prince_. So little did religion actuate her conduct that she challenged Elizabeth to do to the Catholics of England what she herself had done to the Protestants of France, promising that if they were destroyed there would be no loss of her good will.[77] The levity of her religious feelings appears from her reply when asked by Gomicourt what message he should take to the Duke of Alva: "I must give you the answer of Christ to the disciples of St. John, 'Ite et nuntiate quae vidistis et audivistis; caeci vident, claudi ambulant, leprosi mundantur.'" And she added, "Beatus qui non fuerit in me scandalizatus."[78]
