Some (Roman) Catholic writers say that he had become enlightened by Bossuet’s _Exposition of the Doctrines of the Catholic Church_,—a book, indeed, well arranged, soberly penned, and of wonderful skill, in which the author hides the greatest errors of doctrine and practice of (Roman) Catholicism under the artifices of deeply-studied diction. It is possible that the old soldier did not investigate very narrowly, and that his limited information upon controversial questions might have failed to protect him against the subtilties of the theologian. The Reformed historians explain the matter otherwise. They relate that Turenne, who was at all times lax in his religion, had only been retained in it by his wife and his sisters, Mesdames de Duras and de la Trémoille, both very zealous for the Reformed belief. When he was left alone, and had surrendered himself to gallantries little compatible with the faith, he accepted the reasoning of Bossuet. This is the place to observe that the greater part of the court nobility,—the families of Bouillon, Châtillon, Rohan, Sully, La Trémoille,—regulating themselves by the will of the monarch, had one by one re-entered the (Roman) Catholic church. Their licentious manners had also prepared them for abjuration; these were not less inordinate than those of the rest of the courtiers, according to the testimony of Tallemant des Réaux, who was himself a Calvinist by birth. Among the people of importance, who had remained faithful to the Reformation, we may cite the Count de Schomberg, who had been commander-in-chief of the armies; the Duke de la Force and his house; a younger branch of the family of La Rochefoucault; several descendants of Duplessis-Mornay; the Marquises de Ruvigny, of whom one was minister-plenipotentiary at London, and the other deputy-general of the churches. The lesser nobility in the provinces had been more firm than the great noblemen. Languedoc, Guienne, Quercy, Saintonge, Poitou, Normandy, still reckoned thousands of gentlemen devoted to the faith of their fathers, and who, in return for the good services they rendered to the king in his armies and his fleets, asked only for a little justice and protection. XIII. The abjuration of Turenne renewed the projects of reunion, which had never been entirely abandoned since the attempt of Cardinal de Richelieu. The Prince de Conti, governor of Bas-Languedoc, desirous of making himself agreeable to Louis XIV., had already renewed the endeavour in 1661. The provincial synod of Nismes answered him, in the rude language of the period, by the mouth of their moderator Claude, that the Reformed would be guilty of unpardonable cowardice if they consented to “_unite light with darkness, Christ with Belial_.”
