Enchiridion symbolorum, definitionum et declarationum de rebus fidei et morum
The Enchiridion is a compendium of all basic texts of Catholic dogma and morality since the apostles. Commissioned by Pope Pius IX, it has been in use since 1854, and has been updated since. Enchiridion (from Greek cheir, "hand") means "handbook."
The Enchiridion is sometimes referred to as Denzinger, after its first editor, Heinrich Joseph Dominicus Denzinger. It is commonly abbreviated 'Dz' in early editions and 'DS' in editions edited by Schönmetzer due to a revisioning in numbering. By including all basic texts of Catholic teachings, it is a compendium of faith through the centuries. It is also a search instrument for theologians, historians and anybody interested in Christianity. The latest updates extend to the teachings of Pope John Paul II. The Enchiridion can thus be used for research on contemporary issues, such as the social teachings of the Church, subsidiarity, poverty, social justice, death penalty, birth control or the ordination of women. The Enchiridion, published originally as "Enchiridion Symbolorum et Definitionum" is today published as "Enchiridion symbolorum, definitionum et declarationum de rebus fidei et morum". In 2012 Ignatius Press published a bilingual Latin-English version of the 43rd 2010 edition of Denzinger-Hünermann with entries up to 2008 A.D. This English edition was edited by Robert Fastiggi and Anne Englund Nash.
The Enchiridion is chronologically ordered, starting with the Symbolum Apostolicum. It includes the teachings of popes and ecumenical councils since. It does not repeat all the full texts, but only those central parts which are relevant to dogmatic or moral theology. All texts in Denzinger-Schönmetzer listed in Latin. Since the 37th edition of Denzinger-Hünermann (1991), the original language (mostly Latin) is put in the left-hand column with a corresponding vernacular translation in the right hand column. In addition to the 2012 English edition of Denzinger-Hünermann, there are also editions in French, Italian, Spanish, and other languages (as well as the original German of Denzinger-Hünermann).
In addition to the texts, the Enchiridion supplies certain indices:
- Index scripturisticus, on the uses of scripture in various dogmas
- Index systematicus of dogmatic and moral Church teachings
- Index alphabeticus of names and subjects
Quote of Cardinal Gibbons
James Gibbons, Cardinal Archbishop of Baltimore, co-author and driving force behind the Baltimore Catechism stated, that every theologian should have always two books at hand, the Holy Bible and this Enchiridion.
- Optandum est, ut quilebet Theologiae lector semper duo volumina praemanibus habeat: Bibliam Sacram et hoc Enchiridion: ita ut, si omnibus non licet omnia catolicae traditionis monumenta consulere, ea saltem, quae maxima authentica sunt et quasi medullam aliorum continent, frequenter adire possint.
