Six years later he was joined in exile by Pasquier Quesnel who succeeded him as leader of the party. Long before his flight from France Quesnel had published a devotional commentary--_Réflexions morales sur le Nouveau Testament_--which had gone through many editions without exciting official suspicion. But in 1695 Louis Antoine de Noailles, bishop of Châlons, was made archbishop of Paris. He was known to be very hostile to the Jesuits, and at Châlons had more than once expressed official approval of Quesnel's _Réflexions_. So the Jesuit party determined to wreck archbishop and book at the same time. The Jansenists played into their hands by suddenly raising (1701) in the Paris divinity school the question whether it was necessary to accept the condemnation of Jansen with interior assent, or whether a "respectful silence" was enough. Very soon ecclesiastical France was in a blaze. In 1703 Louis XIV. wrote to Pope Clement XI., proposing that they should take joint action to make an end of Jansenism for ever. Clement replied in 1705 with a bull condemning respectful silence. This measure only whetted Louis's appetite. He was growing old and increasingly superstitious; the affairs of his realm were going from bad to worse; he became frenziedly anxious to propitiate the wrath of his maker by making war on the enemies of the Church. In 1711 he asked the pope for a second, and still stronger bull, that would tear up Jansenism by the roots. The pope's choice of a book to condemn fell on Quesnel's _Réflexions_; in 1713 appeared the bull _Unigenitus_, anathematizing no less than one-hundred-and-one of its propositions. Indeed, in his zeal against the Jansenists the pope condemned various practices in no way peculiar to their party; thus, for instance, many orthodox Catholics were exasperated at the heavy blow he dealt at popular Bible reading. Hence the bull met with much opposition from Archbishop de Noailles and others who did not call themselves Jansenists. In the midst of the conflict Louis XIV. died (September 1715); but the freethinking duke of Orleans, who succeeded him as regent, continued after some wavering to support the bull. Thereupon four bishops appealed against it to a general council; and the country became divided into "appellants" and "acceptants" (1717). The regent's disreputable minister, Cardinal Dubois, patched up an abortive truce in 1720, but the appellants promptly "re-appealed" against it. During the next ten years, however, they were slowly crushed, and in 1730 the _Unigenitus_ was proclaimed part and parcel of the law of France. This led to a great quarrel with the judges, who were intensely Gallican in spirit (see GALLICANISM), and had always regarded the _Unigenitus_ as a triumph of ultramontanism. The quarrel dragged indefinitely on through the 18th century, though the questions at issue were really constitutional and political rather than religious.
