Jean-Pierre Gury was a French Jesuitmoral theologian. He is accounted one of the restorers of the old casuisticmethod, a fact that made him worthy of personifying the "Jesuit Moral" in the eyes of some, who, especially in Germany, attacked his doctrine. An ardent follower of Hermann Busenbaum and of Alphonsus Ligouri, he contributed largely towards the final defeat of Jansenism.
It was in 1850, after his return from Rome necessitated by the events of 1848, that the first edition of his Compendium theologiæ moralis appeared, which at the time of the author's death had reached the seventeenth edition, to mention neither the German translation of Wesselack, not the imitations and adaptations published in Belgium, Italy, Spain, Austria, and Germany. In the last-named country the annotated edition of Professor Seitz itself already reached the fifth edition in 1874. Deserving of note is the specially annotated edition of Antonio Ballerini and D. Palmieri ; the edition of Dumas ; the abridged edition of Sabetti-Barret ; the edition adapted to Spain and Latin America by Ferreres ; finally the "Compendium ad mentis P. Gury" by Bulot. In 1862, Gury published his Casus conscientiæ in præcipuas quæstiones theologiæ moralis". Of this work the following editions have appeared: Dumas, 8th ed., Lyons, 1891; Ferreres, for the second time in 1908 ; and a German edition at Ratisbon. The brevity of the compendium led inevitably to a lack of scientific solidarity. For the uses of his classes at Vals, Gury lithographed a more scientific manual which was never published. His mind was essentially practical, orderly and clear. His method was to proceed by question and answer, taking in the exposition of principles and their conclusions, and finally adding the discussion of more special points. He also knew how to blend happily in his lessons solidity and variety, a quality that gained for him the appointment to the chair of moral theology at the Roman College from Father General Roothaan. Opportunity for actual contact with souls was afforded him by numerous confessions, which he heard during retreats and missions conducted by him in vacations.
