Grâce
He became known to the academic world in 1632, by a publication of a defense of the Jesuit doctrine of Divine grace against the Oratorian Gibieuf. In 1644 he began a series of more lengthy contributions of the famous controversy that sought to reconcile human freedom with Divine efficacious grace. He was prominent in defending Catholic orthodoxy against the attacks of the Port-Royal theologians, and in consequence came to the notice of Pascal, who directed the last of the "Provincial Letters" against Père Annat. A full description of his published works may be found in Carlos Sommervogel's "Bibliothèque de la Compagnie de Jésus" (Jesuit Bibliography). A complete edition, in three volumes, of his writings appeared in Paris, in 1666, under the title "Opuscula Theologica". He died in Paris.
