Among the principal evidences in favour of the Vaudois, I must here refer to the large collection of edicts respecting them, published by the court of Turin. It is deemed unnecessary to recapitulate their dates. The Monk Belvedere, chief of a mission, sent to convert the Vaudois in 1630, in his answer to the College of Propaganda fide,* excuses himself for not having converted a single person, because "the valleys of Angrogna have always, and at every period, been inhabited by heretics."--Again, Reynerus Sacco, expressly appointed by the court of Rome, Inquisitor against the Vaudois, goes still farther than Belvedere; and in a book he published against them, calls them Leonists, from one of their ministers named Leon, who lived in the third century; he affirms that no sect was so pernicious to the church as the Leonists; and this for three reasons: 1st. Because it was the most ancient of all; some deriving its origin from the time of Pope Sylvester (the fourth century), and others from the Apostles themselves. 2ndly, Because it was the most extensive, there being scarcely any country into which it had not penetrated; and, 3dly, That instead of inspiring horror as other sects did, by their frightful blasphemies against the Divinity, it had a great appearance of piety; since its members "lived justly before men, believed rightly on God, and received the Apostles' Creed; but they blasphemed against the Roman church and clergy."** * Relatione al consiglio de Prop. Fid. Turin, 1636. ** Bibliothèque des Pères, de Gretserus Traité contra les Vaud. The most obstinate opponents of the antiquity of the Vaudois must give way before the authority of Claude de Seyssel, Archbishop of Turin, who has this passage in his book against us, printed by privilege of Francis the First of France: "The sect of Vaudois," says he, "took its origin from one Leon, a truly religious man, who, in the time of Constantine the Great, detesting the extreme avarice of Pope Sylvester, and the lavish expenditure of Constantine, preferred living in poverty, with simplicity of faith, to the reproach of accepting a rich benefice with Sylvester. To this Leon all attached themselves who thought rightly of their Creed." The same author, after having made useless researches after the commencement of the Vaudois sect, concludes with these remarkable words: "That there must be some important and efficacious reason why this Vaudois sect had endured during so many ages. Again; all kind of different attempts to extirpate them have been made at different times, but they always remained victorious, and absolutely invincible, contrary to the expectation of all." The reader will observe that this expression, "during so many ages," was written by Seyssel in 1500.
