Catholic Encyclopedia (1913)/Constantine, Baron von Schäzler
Theologian, b. at Ratisbon, 7 May, 1827; d. at Interlaken, 9 September, 1880. By birth and training a Protestant, he was a pupil at the Protestant gymnasium St. Anna of Ratisbon; took the philosophical course at the University of Erlangen in 1844-45; then studied law at Munich, 1845-47, and at Heidelberg, 1847-48. After this he decided to enter military life and became a Bavarian officer; in 1850, however, he left the army, received the degree of Doctor of Laws at Erlangen, and took up the practice of law. He entered the Catholic Church at Brussels on 10 October, 1850, and began the study of theology. At Louvain in 1851 he entered the Society of Jesus; after completing the studies he was ordained priest at Liege on 11 September, 1856; in 1857 he left the Society and went on with his studies at Munich where in 1859 he took the degree of Doctor of Theology. In 1861 he became a tutor m the seminary at Osnabruck; in 1862 privatdozent in the history of dogma at Freiburg; in 1866 archiepiscopal councillor. During the Vatican Council (1869-70) he was at Rome as theologian to Bishop Fessler; in 1873 he settled at Rome; in 1874 he was made a domestic prelate and was employed as consultor to various congregations. Shortly before his death he re-entered the Society of Jesus. Schäzler's acuteness and learning made him one of the most prominent representatives of Thomism. He was the author of the following works: "Die Lehre von der Wirksamkeit der Sakramente ex opere operato in ihrer Entwicklung innerhalb der Scholastik und ihrer Bedeutung für die christliche Heilslehre dargestellt" (Munich, 1860); "Natur und Uebernatur. Das Dogma von der Gnade und die theologische Frage der Gegenwart. Eine Kritik der Kuhn'schen Theologie" (Mainz, 1865); "Neue Untersuchungen über das Dogma von der Gnade und das Wesen des christlichen Glaubens" (Mainz, 1867) (these last two works belong to the controversy that Schäzler carried on with Johannes von Kuhn, q. v.); "Das Dogma von der Menschenwerdung Gottes, im Geiste hes hl Thomas dargestellt" (Freiburg, 1870); "Die päpstliche Unfehlbarkeit aus dem Wesen der Kirche bewiesen. Eine Erklärung der ersten dogmatischen Constitution des vaticanischen Conncils über die Kirche Christi" (Freiburg, 1870); "Divus Thomas Doctor angelicus contra Liberalismum invictus veritatis catholicae assertor" (Rome, 1874); "Introductio in s. theologiam dogmaticam ad mentem D. Thomae Aquinatis", a posthumous work ed. by Thomas Esser (Ratisbon, 1882); "Die Bedeutung der Dogmengeschichte vom katholischen Standpunkt aus erortert", ed. Thomas Esser (Ratisbon, 1884).
