This on the face of it is no letter from one young man to another. It is the artful production of the zealot and bigot in one, well informed of the antecedents of the man he is denouncing, and but poorly disguised by the name under which he is writing. The letter from first to last is Calvin’s, and was accompanied by the two first leaves of the newly printed book, the ‘Christianismi Restitutio,’ containing the title and table of contents, sufficient, as Calvin knew full well, to alarm the hierarchs of Papal Christianity, which in their estimation needed no restoration, and was indeed susceptible of none; whilst any discussion of such transcendental topics as the Trinity, Faith in Christ, Regeneration, Baptism, and the Reign of Antichrist, smacked at best of schism when undertaken by a layman even of orthodox views, but became flat blasphemy when treated by such a one in any adverse sense. Cardinal Tournon, at this time Archbishop of Lyons, was the implacable enemy of all innovators, and in his zeal for what he believed to be the truth well disposed to resort to the severest measures against the spread of heresy, which to him and his co-religionists, then as now, was most especially embodied in the principles of Luther and Calvin’s Reformation. Exposed as were the south and east of France from their contiguity with Switzerland to infection of the kind, Tournon had not relied exclusively on himself and his own subordinate clergy as watchers over the faith of the district under his charge. He had further summoned to his aid one of the regularly trained inquisitors from Rome, Matthew Ory by name, who designated himself: _Pénitencier du Saint Siége Apostolique, et Inquisiteur général du Royaume de France et dans toutes les Gaules_. This man, as we may imagine, had a real relish for his calling and was watchfulness itself in ferreting out heresy, as, with all of his kind, he was relentless in pursuing it to the death. The notable letter of Trie to Arneys was immediately brought under the notice of the clergy of Lyons, as Calvin intended and foresaw that it would be; and by one of them, was communicated to Ory, the Inquisitor, and to Bautier, Vicar-General, and Canon of the Cathedral Church of Lyons. Here was work of more than common interest to the Inquisitor, who proceeded forthwith, under date of March 12, 1553, to write to Villars, Auditor of Cardinal Tournon, absent at the moment from Lyons, but no farther away than his Château of Roussillon, a few miles distant from Vienne.
