Bossuet appealed to the civil authority, denouncing Dupin to the Chancellor of France, Louis Boucherat and to Archbishop de Harlay of Paris. Bossuet simply enumerated the points in the Bibliothèque of which he disapproved. These concerned original sin, purgatory, the canonicity of the Sacred Scriptures, the eternity of hell's torments, the veneration of saints and of their relics, the adoration of the Cross, grace, the pope and the bishops, Lent, divorce, the celibacy of the clergy, tradition, the Eucharist, the theology of the Trinity, and the Council of Nicæa. He demanded a censure and a retractation. Like Petit-Didier, Bossuet would not admit that any of the Greek or Latin Fathers differed from St. Augustine on the subject of grace, nor that this matter could be called subtle, delicate, and abstract. Between Dupin and Bossuet there was a still wider difference and Bossuet wrote, "The liberty M. Dupin takes of so harshly condemning the greatest men of the Church should, in general, not be tolerated". On the other hand, Bossuet strongly contended that heretics could not be too severely dealt with: "It is dangerous to call attention to passages that manifest the firmness of these people without also indicating wherein this firmness has been overrated: otherwise they are credited with a moral steadfastness which elicits sympathy and leads to their being excused". Dupin submitted, but was nevertheless condemned by the Archbishop of Paris (14 April 1696). Dupin continued his Bibliothèque, which was put on the Index long after his death (10 May 1757), though other works of his were condemned at an earlier date. He was also criticized by Richard Simon, though the two had similar views and employed similar methods so that when Bossuet was writing the Défense de la Tradition et des Saints Pères (which did not appear, however, until 1743), he included both in his invectives against the "haughty critics" who inclined to rabbinism and the errors of Socinus. Although Dupin spoke favourably of Arnauld and signed the "Cas de conscience", he was not a Jansenist. Rather, on these matters he shared the opinions of Launoy, who "had found a way to be at once both demi-Pelagian and Jansenist". Exile and return Dupin was pre-eminently a Gallican. It was probably on this account that Louis XIV had him exiled to Châtellerault, on the occasion of the "Cas de conscience". Dupin retracted and returned, but his chair in the
