Heinrich Joseph Dominicus Denzinger

Heinrich Joseph Dominicus Denzinger (10 November 1819 – 19 June 1883) was a leading German Catholic theologian and author of the Enchiridion Symbolorum et Definitionum (Handbook of Creeds and Definitions) commonly referred to simply as "Denzinger".

Heinrich Denzinger was born on 10 October 1819 at Liege. In 1831 his father, who was a professor at the Liege University, took him to Würzburg, the original home of the family. Here he attended the gymnasium and studied philosophy at the university, where he received the Ph.D. degree. In 1838 he entered the Würzburg seminary, went to the German College at Rome in 1841, was ordained priest in 1844, and the following year took a degree in theology.

On his return home he was first curate at Hassfurt-on-the-Main, became professor extraordinary of dogmatic theology at Würzburg in 1848, and ordinary professor in 1854. He continued to occupy this position, in spite of ill-health, until his death. Denzinger was one of the pioneers of positive theology and historical dogmatic (Dogmengeschichte) in Catholic Germany. In the generation after Johann Adam Mohler (d. 1838) and Döllinger (1799-1890) he carried on their methods and helped to establish what was the special character of the German school, exact investigation of the historical development of theology, rather than philosophical speculation about the corollaries of dogma.

He died on 19 June 1883 at Würzburg.

Nearly all his important works are in the nature of historical theology. The best-known and most useful is his Enchiridion Symbolorum et Definitionum (first ed., Würzburg, 1854), a handbook containing a collection of the chief decrees and definitions of councils, list of condemned propositions, etc., beginning with the oldest forms of the Apostles' Creed. The first edition contained 128 documents; by the sixth edition, the last edited by Denzinger himself, that number had increased to 202.

After Denzinger's death, Professor Ignatius Stahl continued the work of re-editing the Enchiridion with additional decrees of Leo XIII. Clemens Bannwart, S.J., prepared a revised and enlarged edition (10th ed., Freiburg) in 1908.
