There were also a few modern Jesuits who were conspicuous in moral theology. First, in point of time was Jean-Pierre Gury, who was born in Mailleroncourt on January 23, 1801. He taught theology for thirty-five years at Annecy and at the Roman College. He died on April 18, 1866. His work was adopted as a text-book in a number of seminaries, because of its brevity, honesty and solidity. It is true that his brevity impaired his accuracy at times, as well as the scientific presentation of questions, but his successors such as Seitz, Cercia, Melandri and Ballerini filled up the gaps by the help of the decisions of the Congregations and the more recent pronouncements of the Holy See. Besides his "Moral Theology" he also published his "Casus conscientiæ." That made him the typical "Jesuit Casuist," and drew on him all the traditional hatred of Protestant polemicists, especially in Germany. His work did much to extirpate what was left of Jansenism in Europe.
Antonio Ballerini held the chair of moral theology in the Roman College from 1856 until his death in 1881. In the cautious words of Hurter he was "almost the prince of moralists of our times." Besides his "Principi della scuola Rosminiana" he wrote his remarkable "Sylloge monumentorum ad mysterium Immaculatæ Conceptionis illustrandum," and in 1863 issued his "De morali systemate S. Alphonsi M. de Ligorio." In 1866 appeared his "Compendium theologiæ moralis." The style was somewhat acrid, and sharp, especially in the controversy it provoked with the out-and-out defenders of St. Alphonsus. His annotations were a mine of erudition and revealed at the same time a very unusual intellectual sagacity and correctness of judgment. His book, on the whole, exercised a great influence in promoting solid theological study; and its denunciation of the frivolous reasons on which many opinions were based and the unreliableness of many quotations decided the tone of subsequent works by other authors. Following Ballerini were other Jesuits such as Lehmkuhl, Sabbetti, Noldin, Genicot and Palmieri, who won fame as moralists.
Palmieri was not only a theologian, a moralist and a philosopher, but an exegete. He taught Scripture and the Oriental languages in Maastricht for seven years, and in 1886, published a Commentary on the Epistle to the Galatians and another on the historicity of the Book of Judith. He was among the first to sound the alarm about Loisy's heterodoxy and he wrote several books against the Modernistic errors. His reputation rests chiefly on his dogmatic theology; every two years, from 1902, he issued treatises that immediately attracted attention for their brilliant originality and exhaustive learning. He died in Rome on May 29, 1909. "This superlatively sagacious man," says Hurter, "blended Gury and the super-abundant commentaries of Ballerini into one continuous text, injecting, of course, his own personal views into his seven great volumes, with the result that it is a positive pleasure to read him." The wonderful theological acumen manifested in this, as in his other works apparently restored him to favor with Leo XIII, who disliked some of his philosophical speculations. Hence, when Father Steinhüber was made cardinal, Palmieri was appointed to succeed him as theologian of the Penitentiaria.
Besides all this, Palmieri gave a delightful revelation of his affectionate character as a devoted son, when he wrote, at the request of his mother, a Commentary of Dante. Ojetti says that "he brought all the profundity of his philosophy and theology to his task and produced a work which astonished those who were able to appreciate the depth of the thought and the scientific erudition employed in the exposition of each individual canto."
The great Perrone was born in Chieri in 1794 and entered the Society on December 14, 1815, one of the first novices after the Re-establishment. He began his career as professor of dogma at Orvieto, and from thence was transferred to Rome, where he remained until the outbreak of the Revolution in 1848. After a three years' stay in England he resumed his place at the Roman College. He was consultor of various congregations, was conspicuous as the antagonist of Hermes, and also in the discussion that ended in the dogmatic definition of the Immaculate Conception. His "Prælectiones theologiæ" in nine volumes reached its thirty-fourth edition, while its "Compendium" saw fifty-seven.
Carlo Passaglia is another great theological luminary. He entered the Society in 1827, and when scarcely thirty years old was teaching at the Sapienza and was prefect of studies at the Collegium Germanicum. The Gregorian University then claimed him, and, in 1850, he took a leading part in preparing the definition of the dogma of the Immaculate Conception on which he wrote three large volumes. Other great works are to his credit, but his historico-linguistic method met with criticism. It was said he substituted grammar for dogma. Passaglia left the Society, however, in 1859. Pius IX gave him a chair in the Sapienza; there he came in contact with an agent of Cavour and under his influence wrote his book "Pro causa italica". It was placed on the "Index," and Passaglia fled to Turin, where he taught moral philosophy until his death and edited a weekly called "Il Medicatore," which welcomed articles from discontented priests. He also published a daily paper called "La Pace," as well as "Il Gerdil," a theological review. He was suspended from his priestly functions, dressed as a layman, and was temerarious enough to criticise the Syllabus. The Bishop of Mondovi tried to reconcile him with the Church, but he did not retract until a few months before his death. Hurter calls him "an illustrious professor of dogma who was carried away by politics, left the Society, assailed the Temporal Power, and by his sad defection cast a stain on his former glory. His quotations from the Fathers are too diffuse, and although his work on the Immaculate Conception displays immense erudition it crushes the reader by its bulk."
Carlo Maria Curci also brought grief to his associates in those days. He had acquired great fame for his defense of the rights of the Pope against the Liberal politicians of the Peninsula, but unfortunately, soon after, became a Liberal himself and left the Society. He returned again, however, shortly before his death which occurred on June 19, 1891. He was one of the first contributors to the "Civiltà" and was, besides, a remarkable orator. His "Nature and Grace," "Christian Marriage," "Lessons from the two books of the Machabees and the Four Gospels," and "Joseph in Egypt" were the most notable of his writings.
Josef Wilhelm Karl Kleutgen was a Westphalian. He entered the Society on April 28, 1834, at Brieg; to avoid difficulties with the German Government he became a naturalized Swiss, and for some time went by the name of Peters. In 1843 he was professor of sacred eloquence in the Collegium Germanicum, and subsequently was named substitute to the Secretary of Father General, consultor of the Congregation of the Index, and collaborator in the preparation of the Constitution "De fide catholica" of the Vatican Council. He wrote the first draft of Pope Leo's Encyclical "Æterni Patris" on the revival of Scholastic theology and philosophy. His knowledge of the writings of the Angelic Doctor was so great that he was called Thomas redivivus. His first work "Theologie der Vorzeit" and his "Philosophie der Vorzeit" against Hermes, Hirscher, and Günther were declared to be epoch-making. The writing of these books coincided with a remarkable event in his life, namely suspension from his priestly office for his imprudence in allowing a community of nuns under his direction to honor as a saint one of their deceased members. He went into seclusion consequently but at the opening of the Vatican Council he was recalled by Pius IX to take part in it. All his works excel in solidity of doctrine, accuracy and brilliancy of exposition and nobility of style.
Johann Franzelin was a Tyrolese. He entered the Society on 27 July, 1834, but passed most of his life outside of his country. He studied theology in Rome, and became such an adept in Greek and Hebrew that he occupied the chair when the professor was ill. He had to leave the city in the troublous times of 1848, but on his return he gave public lectures in the Roman College on Oriental languages. In 1857 he began his career as professor of dogma and his immense erudition caused him to be called for in many of the Roman congregations. In 1876 Pius IX created him cardinal. His theological works are known throughout the Church for their solidity, erudition and scrupulous accuracy. His dignity made no change in his simple and laborious life. He continued until the end of his days to wear poor garments, occupied two small rooms in the Novitiate of Sant' Andrea, rose at four every morning and spent the time until seven in devotional exercises. He kept up his penitential practises till death came on 11 December, 1886.
