The king's conciliatory policy triumphed in a quarrel which broke out between Rome and Venice. The Papacy desired to enforce a system of its own in matters of Church and State, and, in other words, to make laws for the nations to obey. The Canon Law did not come down from heaven, but was enacted from time to time in the past, and was to be enacted furthermore in the future. Venice, as a modern state, self-sufficing and concentrating power, legislated for its clergy as well as for its laity, resenting interference outside questions of pure doctrine. The two pretensions clashed under Paul V, a zealous and uncompromising pontiff, the founder of the House of Borghese. He claimed a jurisdiction in Venice which could not have been asserted successfully in France or Spain, because a surrender of authority which may be made to superior force cannot be made voluntarily where there is no compulsion. But the court of Rome was the chief seat of those aspirations after the control of states, which had been so lately renewed. Since the failure of the schemes against Elizabeth and the victory of Gallicans over the League and the medieval ideal, a new heresy, the political heresy, had been discovered, which Cardinal Baronius, the foremost of the Roman divines, denounced as the most damnable of all heresies. By that was meant the notion of a science of politics limiting the ecclesiastical domain; an ethical and political system deriving its principles elsewhere than from the Church, and setting up a new and rival authority yet to be defined, ascertainable in no book, and not accepted by the nations. Those amongst us who deny the existence of a political science, and believe that ethics cannot be made to include politics, have ardent supporters in the Roman clergy of three centuries ago. The Venetian theorists who could be caught were burnt at Rome. One, who did not trust himself in Roman hands, was badly wounded near his own door. This was the famous Father Paul, whose History of the Council of Trent issued from this controversy. He was a Servite monk and theological adviser to the government, and the emissaries who flocked from England, France, Geneva, and the German states, to see how far the Venetians would move away from Rome, believed that he was at heart a Calvinist. In reality Sarpi had more of the eighteenth century than of the sixteenth in his turn of mind, and stood far aloof from the doctrines over which his contemporaries contended, and the expectations entertained of his countrymen were illusory. The city was placed under an interdict, and the orders that were faithful to Rome departed across the Lagoon, singing hymns. The Pope looked about for means of coercion when Henry mediated. He owed much to Venice, which was the first of the Catholic Powers to recognise him. In action, he called to his men to watch where his white plume waved, and to follow wherever they saw it.
