Page "Jansenism" Paragraph 22

Then Jesuits attacked the Jansenists, claiming they were guilty of heresy similar to that of the Calvinists.

In response, Arnauld wrote Théologie morale des Jésuites ( Moral Theology of the Jesuits ), which was the basis of most of the arguments later used by Pascal in his Provincial Letters denouncing the " relaxed morality " of Jesuitism.

The Jesuit Nicolas Caussin, former spiritual director to Louis XIII, was charged by his order with writing a defense against Arnauld's book, titled Réponse au libelle intitulé La Théologie morale des Jésuites ( 1644 ).

Other works published against Arnauld's Moral Theology of the Jesuits included the one written by the Great Jesuit polemist François Pinthereau ( 1605 – 1664 ), under the pseudonym of " the abbé de Boisic ", titled Les Impostures et les ignorances du libelle intitulé: La Théologie Morale des Jésuites ( 1644 ).

Pinthereau was also the author of a critical history of Jansenism titled La Naissance du Jansénisme découverte à Monsieur le Chancelier ( The Birth of Jansenism Revealed to the Chancellor, Leuven, 1654 ).
