Subsidiary works followed rapidly from his pen, strengthening the civil power against the clerical; but in 1610 came a treatise, which marked an epoch,--his History of Ecclesiastical Benefices.[2] In this he dealt with a problem which had become very serious, not only in Venice, but in every European state, showed the process by which vast treasures had been taken from the control of the civil power and heaped up for ecclesiastical pomp and intrigue, pointed out special wrongs done by the system to the Church as well as the State, and advocated a reform which should restore this wealth to better uses. His arguments spread widely and sank deep, not only in Italy, but throughout Europe, and the nineteenth century has seen them applied effectively in every European country within the Roman obedience. [2] The old English translation of this book, published in 1736 at Westminster, is by no means a very rare book, and it affords the general reader perhaps the most accessible means of understanding Fra Paolo's simplicity, thoroughness, and vigor. In 1611 he published his work on the Inquisition at Venice, presenting historical arguments against the uses which ecclesiasticism, under papal guidance, had made of that tribunal. These arguments spread far, and developed throughout Europe those views of the Inquisition which finally led to its destruction. Minor treatises followed, dealing with state questions arising between the Vatican and Venice, each treatise--thoroughly well reasoned and convincing--having a strong effect on the discussion of similar public questions in every other European nation. In 1613 came two books of a high order, each marking an epoch. The first of these was upon the Right of Sanctuary, and in it Sarpi led the way, which all modern states have followed, out of the old, vicious system of sanctioning crime by sheltering criminals. The cogency of his argument and the value of its application gained for him an especial tribute by the best authority on such questions whom Europe had seen,--Hugo Grotius. Closely connected with this work was that upon the Immunity of the Clergy. Both this and the previous work were in the same order of ideas, and the second fastened into the European mind the reasons why no state can depend upon the Church for the punishment of clerical criminals. His argument was a triumphant vindication of Venice in her struggle with Paul V on this point; but it was more than that. It became the practical guide of all modern states. Its arguments dissipated the last efforts throughout Europe to make a distinction, in criminal matters, between the priestly caste and the world in general.
