{{Canon Law}}
The {{lang|la|'''Decretum Gratiani'''}}, also known as the {{lang|la|'''Concordia discordantium canonum'''}} or {{lang|la|'''Concordantia discordantium canonum'''}} or simply as the {{lang|la|'''Decretum'''}}, is a collection of [[Canon law of the Catholic Church|Catholic canon law]] compiled and written in the 12th century as a legal textbook by the [[jurist]] known as Gratian. It forms the first part of the collection of six legal texts, which together became known as the {{lang|la|[[Corpus Juris Canonici]]}}. It was used as the main source of law by [[Canon law|canonists]] of the [[Catholic Church]] until the [[Decretals of Gregory IX|''Decretals'']], promulgated by [[Pope Gregory IX]] in 1234, obtained legal force, after which it was the cornerstone of the {{lang|la|Corpus Juris Canonici}}, in force until 1917.<ref>{{cite web |series=Code of Canon Law - IntraText |url=https://www.encyclopedia.com/religion/encyclopedias-almanacs-transcripts-and-maps/gregory-ix-decretals|title=Decretals of Gregory IX|access-date=24 May 2020}}</ref>

==Overview==
In the first half of the 12th century [[#Author|Gratian]], ''clusinus episcopus'',<ref name=Reali_2009>Reali, Francesco (ed.), {{lang|it|Graziano da Chiusi e la sua opera}}, 2009, pp. 63-73 and p. 244 has found and re-evaluated a Kalendarium of the Sienese Church owned by the Library of the Intronati of Siena (Ms FI2, f. 5v) in which, in Carolina minuscule writing with a date that at most can be placed in the mid-12th century, reads the following (after {{lang|la|Augusti IIII idus Obiit&nbsp;...}}): {{lang|la|et gratianus clusinus episcopus}}; Reali observes that the text conforms to another reliable source of the 12th century, in which the author of the Decretum (who drafted the work in 1130) is referred to as {{lang|la|italic=no|"Gratianus clusinus episcopus"}} (Robertus de Monte, Cronica, Bethman [ed.], ''MGH Scriptores'' VI, Hanover 1844, p. 490) and that other sources of the twelfth and thirteenth centuries also speak of Gratian as bishop or as bishop of Chiusi.</ref> probably a jurist of the ecclesiastical forum and a teacher, {{lang|la|rubricator}} at the monastery of Saints Nabor and Felix (according to the Bolognese [[Odofredus|Odofredus Denariis]] [13th century]) and starting from the 18th century believed to have been a [[Camaldolese]] monk,<ref name=catenc/> composed the work he called {{lang|la|Concordia discordantium canonum}}, and others titled {{lang|la|Nova collectio, Decreta, Corpus juris canonici}}, or the more commonly accepted name, {{lang|la|Decretum Gratiani}}, a living text, characterized by multiple editorial stages. He did this to obviate the difficulties which beset the study and the forensic application of practical, external theology ({{lang|la|theologia practica externa}}), i.e., the study and the forensic use of canon law. In spite of its great reputation and wide diffusion, the {{lang|la|Decretum}} has never been recognized by the Church as an official collection.<ref>{{Cite conference |last=Kuttner |first=Stephan |title=Research on Gratian: Acta and Agenda |publisher=Vatican Library |publication-date=1988 |book-title=Proceedings of the Seventh International Congress of Medieval Canon Law, Cambridge |date=23–27 July 1984 |editor-last=Linehan |editor-first=Peter |series=Monumenta Iuris Canonici. Series C: Subsidia |publication-place=Vatican City |pages=3–26 |isbn=8821005704}}</ref>

The so-called {{lang|la|vulgata}} or vulgate version (an advanced editorial stage) of the {{lang|la|Decretum}} is divided into three parts ({{lang|la|ministeria}}, {{lang|la|negotia}}, {{lang|la|sacramenta}}).

* The first part is divided into 101 distinctions ({{lang|la|distinctiones}}), the first 20 of which form an introduction to the general principles of canon law ({{lang|la|tractatus decretalium}}); the remainder constitutes a {{lang|la|tractatus ordinandorum}}, relative to ecclesiastical persons and function. 
* The second part contains 36 causes ({{lang|la|causæ}}), divided into questions ({{lang|la|quæstiones}}), and treat of ecclesiastical administration, procedural issues and marriage. {{lang|la|Quaestio}} 3 of {{lang|la|Causa}} 33 on penance ({{lang|la|De penitentia}}) is treated separately and subdivided into 7 distinctions. 
* The third part {{lang|la|De consecratione}} deals with sacramental and liturgical law and contains 5 distinctions.

Each distinction or question contains {{lang|la|dicta Gratiani}}, or [[Maxim (philosophy)|maxims]] of Gratian, and {{lang|la|canones}}. Gratian himself raises questions and brings forward difficulties, which he answers by quoting {{lang|la|auctoritates}}, i. e. canons of councils, decretals of the popes, texts of the Scripture or of the Fathers. These are the {{lang|la|canones}}; the entire remaining portion, even the summaries of the canons and the chronological indications, are called the maxims or {{lang|la|dicta Gratiani}}.

Many {{lang|la|auctoritates}} have been inserted in the {{lang|la|Decretum}} by authors of a later date. These are the {{lang|la|Paleae}}, so called from [[Paucapalea]], the name of the principal commentator on the {{lang|la|Decretum}}. The Roman revisers of the 16th century (1566–1582) corrected the text of the "Decree" and added many critical notes designated by the words {{lang|la|Correctores Romani}}.

=== Citing the {{lang|la|Decretum}} ===
The {{lang|la|Decretum}} is cited by referring to the larger units of the distinction or the cause and question, and then the specific canon or dictum. For clarity, the distinctions of {{lang|la|Causa}} 33, {{lang|la|quaestio}} 3 of the second part are referred to as {{lang|la|De penitentia}} (or {{lang|la|De pen.}}), while the distinctions of the third part are referred to as {{lang|la|De consecratione}} (or {{lang|la|De cons.}}). The Part is usually not included, as the citation form is different for each.

Citation styles for the {{lang|la|Decretum}} have changed over time and can generally be categorised under the modern, obsolescent, and obsolete forms.<ref>{{Cite book |last=Brundage |first=James |title=Medieval Canon Law |publisher=Taylor & Francis |year=2014 |location=London and New York |pages=192–3}}</ref>

==== Modern form ====
This form, common since the twentieth century, cites all units in Arabic numerals, from largest unit to smallest unit.

Distinctions are referenced by an uppercase "D.", Causes by an uppercase "C.", questions by a lowercase "q.", and canons by a lowercase "c.". Gratian's {{lang|la|dicta}} are referred to with a lowercase "d. a. c." ({{lang|la|dictum ante canonem}}, for commentary preceding the canon) or "d. p. c." ({{lang|la|dictum post canonem}}, for commentary following the canon).

Examples:

* [Part I] D. 23 c.7 
* [Part II] C. 15 q. 2 c. 4 
* [Part II] C. 23 q. 8 d. p. c. 25 
* [Part II, {{lang|la|De penitentia}}] D. 3 de pen. c. 24 
* [Part III] D. 2 de cons. c. 82

==== Obsolescent form ====
Commonly used between the seventeenth and early twentieth centuries, this form generally begins with a reference to the smallest unit in Arabic numerals, followed by the Distinction or Cause in Roman numerals and (if required) the question in Arabic numerals, e.g. "c. 5, C.3<!--should be III, surely?--> q.1".

==== Obsolete form ====
This is the form used by medieval and early modern writers, falling out of use after the eighteenth century. Major divisions ({{lang|la|Distinctio, Causa, quaestio}}) were cited with (usually Roman) numerals. Since the numbering of the {{lang|la|Decretum}}'s capitula only became standard in the sixteenth century, canons were cited by their opening word(s). Two or more canons beginning with the same word/phrase might be distinguished with numbers, e.g. {{lang|la|In Christo ii}}.

Examples (using the same references as above):

* {{lang|la|xxiii dist. episcopus}}
* {{lang|la|xv q. ii felix}} 
* {{lang|la|xxiii q. viii § hinc datur}} 
* {{lang|la|iii de pen[itentia] totam}}
* {{lang|la|ii de cons. In Christo ii}}

Early commentators might also refer to the first few canons by number (e.g. {{lang|la|cap. iij}} for the third canon of a distinction), or to the last few canons as {{lang|la|cap. antepenult.}} ({{lang|la|"capitulum antepenultimum"}}, that is, third to last), {{lang|la|cap. penult.}} (or {{lang|la|pen.}} or {{lang|la|pe.}}, second to last), and {{lang|la|cap. fin.}} ({{lang|la|"capitulum finale"}}) or {{lang|la|cap. ult.}} (last).

==Author==
[[File:Graciano.jpg|upright=0.8|thumb|left|Gratian]]

Gratian ({{langx|la-x-medieval|Gratianus}}) was a [[Canon law (Catholic Church)|canon law]]yer from [[Etruria]], probably operating in the former feudal state of [[Matilda of Tuscany]] (mainly in [[Tuscany]] and [[Emilia (region)|Emilia region]]) as well as in [[Reims]] (1131), [[Rome]], [[Bologna]], [[Venice]] (1143) and [[Chiusi]]. He flourished in the second quarter of the twelfth century. He died on 10 August around the middle of the 12th century as bishop of [[Chiusi]] in [[Tuscany]]. Little else is known about him.<ref>{{Cite EB1911 |wstitle= Gratianus, Franciscus |volume = 12 |last= |first= |author-link= |pages=378-379 |short=1}}</ref>

He is sometimes incorrectly referred to as Franciscus Gratianus,<ref>{{Cite EB9|wstitle=Franciscus Gratianus |volume=XI |page=60|short=1}}</ref> Johannes Gratian,<ref name=catenc>{{cite encyclopedia |last=Van Hove |first=Alphonse |url=http://www.newadvent.org/cathen/06730a.htm |title=Johannes Gratian |encyclopedia=Catholic Encyclopedia |volume=6 |publisher=Robert Appleton Co. |location=New York |year=1909 |access-date=19 September 2014}}</ref> or Giovanni Graziano. For a long time he was believed to have been born around 1100, at [[Ficulle]] in [[Umbria]], based on a chronicle of illustrious men of the 14th century attributed to an exponent of the powerful [[Colonna family]], who had possessions in [[Ficulle]]. He was said to have become a monk at [[Camaldoli]] and then taught at the [[monastery]] of [[St. Felix]] in Bologna and devoted his life to studying theology and canon law,<ref>{{cite journal |last=Noonan |first=John T. |title=Gratian Slept Here: The Changing Identity of the Father of the Systematic Study of Canon Law |journal=Traditio |volume=35 |pages=145–172 |year=1979 |doi=10.1017/S0362152900015038|s2cid=148787058 }}</ref> but contemporary scholars do not attach credibility to these traditions.

Since the 11th century, some cities of central-northern Italy such as [[Arezzo]], [[Pisa]], [[Bologna]] had been the centre of the study of [[Roman law]], after the {{lang|la|[[Corpus Juris Civilis]]}} was rediscovered in western Europe. In the second half of the 11th century and at the beginning of the 12th century Roman law was generally studied and applied only in the cities (seat of the diocese) in which there was an imperial Prefecture, where imperial and ecclesiastical jurists (and courts) coexisted (such as [[Pisa]] and [[Bologna]]), with mutual interference. However, from the first editorial stages of the {{lang|la|Decretum}} it is clear that Gratian had little knowledge of Roman law and that he had a great sense of depth in the disputes dealt with in the ecclesiastical seats, especially in the appeal judgments dealt with in the Roman curia. Therefore, some scholars today exclude that he was trained in Justinian Roman law and that (at the beginning of his career) he worked mainly in certain cities (such as [[Arezzo]], [[Pisa]] or [[Bologna]]) where Roman law was known and applied for years, it being plausible that he came from an episcopal city in which all jurisdiction, both civil and ecclesiastical, was dealt with by the only court present: the ecclesiastical one. Perhaps also for this reason he feels the need to create a legal work to be applied only in ecclesial courts and only for cases relating to canon law, putting an end to the mixture between civil and ecclesiastical jurisdictions. It is no coincidence that [[Dante Alighieri]] writes that he helped "one and the other forum", that is, he separated the canonical jurisdiction from the civil one.<ref name=Reali_2020>Reali, Francesco, {{lang|it|italic=no|"Alle origini del diritto civile europeo"}}, in {{lang|la|Studia Gratiana}} 30 (2020), 27–114</ref> Gratian's work was an attempt, using early [[scholasticism|scholastic]] method, to reconcile seemingly contradictory canons from previous centuries. Gratian quoted a great number of authorities, including the [[Bible]], papal and conciliar legislation, church fathers such as [[Augustine of Hippo]], and secular law in his efforts to reconcile the canons. Gratian found a place in [[Dante]]'s ''Paradise'' among the doctors of the Church:<ref>{{cite web |url=http://danteworlds.laits.utexas.edu/paradiso/04sun.html |title=4. Sun |work=Dante's Paradiso |type=lecture notes |publisher=University of Texas at Austin |access-date=3 February 2023}}</ref>

{{blockquote|This next flamelet issues from Gratian's smile, he who gave such help to the [[canon law (Catholic Church)|ecclesiastical]] and [[law|civil]] spheres as is acceptable in Paradise.<ref>[[Dante]], [http://www.poetryintranslation.com/PITBR/Italian/DantPar8to14.htm#_Toc64099871 ''Paradiso'', Canto X], accessed 25 June 2013</ref>
}}
He has long been acclaimed as {{lang|la|Pater Juris Canonici}} ([[Ecclesiastical Latin|Latin]]: "Father of Canon Law"), a title he shares with his successor [[Raymond of Penyafort|St. Raymond of Penyafort]]. Gratian was the father and the first teacher of the {{lang|la|scientia nova}} which he himself coined: the new canon law or {{lang|la|ius novum}}. Many of his disciples have become highly renowned canonists.

==Textual history==
The vulgate version of Gratian's collection was completed at some point after the [[Second Council of the Lateran]] of 1139, which it quotes. Research by [[Anders Winroth]] established that some manuscripts of an early version of Gratian's text, which differs considerably from the mainstream textual tradition, have survived.<ref>Winroth (Cambridge 2004), 138</ref>
With later commentaries and supplements, the work was incorporated into the {{lang|la|[[Corpus Juris Canonici]]}}. The {{lang|la|Decretum}} quickly became the standard textbook for students of canon law throughout Europe, but it never received any formal, official recognition by the papacy. Only the [[1917 Code of Canon Law|{{lang|la|cat=no|Codex Juris Canonici}} of 1917]] put it out of use.<ref name=Crompton>Crompton (2006):174</ref>

As late as 1997, scholars commonly set the date of completion at 1140, but this accuracy in dating is not possible after [[Anders Winroth]]'s groundbreaking scholarship.<ref>Hartmann & Pennington, ''History of Medieval Canon Law in the Classical Period'', pg. 7.</ref> Winroth's research shows that the {{lang|la|Decretum}} existed in two published [[recension]]s.<ref>Winroth, (Cambridge, 2004), 3</ref> The first dates to sometime after 1139, while the second dates to 1150 at the latest. There are several major differences between the two recensions:
*The first recension is a more coherent and analytical work.
*The second recension places a much greater emphasis on papal primacy and power.
*The second recension includes Roman law extracts taken directly from the {{lang|la|Corpus Juris Civilis}}, whereas the first recension does not demonstrate substantial familiarity with Roman jurisprudence.

These differences led Winroth to conclude that Roman law was not as far developed by 1140 as scholars had previously thought. He has also argued that the second recension was due not to the original author of the first recension (whom he calls Gratian 1), but rather another jurist versed in Roman law.<ref>Winroth, (Cambridge, 2004), 146–174</ref> However, Winroth's thesis of two Gratians remains controversial.<ref>See most recently Atria Larson, ''Master of Penance: Gratian and the Development of Penitential Thought and Law, ca. 1120-1215'', Washington, DC: Catholic University Press, 2013, arguing for even greater complexity in the addition and adaptation of the text of the {{lang|la|Decretum}}.</ref>

This field of inquiry is hampered by ignorance of the compiler's identity and the existence of manuscripts with abbreviated versions of the text or variant versions not represented by Winroth's two recensions. One of these is the manuscript St. Gall, {{lang|de|Stiftsbibliothek}}, 673 (=Sg),{{explain|reason=this equals sign and abbreviation seems to be a continental citation practice which isn't comprehensible to English readers|date=February 2023}} which some have argued contains the earliest known draft (Larrainzar's {{lang|es|borrador}}) of the {{lang|la|Decretum}},<ref>{{cite journal |first=Carlos |last=Larrainzar |title=El borrador de la 'Concordia' de Graciano: Sankt Gallen, Stiftsbibliothek MS 673 (=Sg) |language=es |journal=Ius Ecclesiae: Rivista internazionale di diritto canonico |issue=11 |year=1999 |pages=593–666}}</ref> but which other scholars have argued contains an abbreviation of the first recension expanded with texts taken from the second recension.<ref>Lehnherr, Titus, [http://www.t-j-l.de/Sg-Entw.PDF Titus "Ist die Handschrift 673 der St. Galler Stiftsbibliothek (Sg) der Entwurf zu Gratians Dekret?: Versuch einer Antwort aus Beobachtungen an D.31 und D.32"] (unpublished paper) {{webarchive|url=https://web.archive.org/web/20120402122239/http://www.t-j-l.de/Sg-Entw.PDF |date=2012-04-02 }}; Anders Winroth, "Recent Work on the Making of Gratian's {{lang|la|italic=no|Decretum}}", ''Bulletin of Medieval Canon Law'', n.s. 26 (2004–2006): 1–29; John Wei, "A Reconsideration of St. Gall, Stiftsbibliothek 673 (Sg) in light of the Sources of Distinctions 5–7 of the {{lang|la|italic=no|De penitentia}}", ''Bulletin of Medieval Canon Law'', n.s. 27 (2007): 141–180.</ref>

== Criticism ==
During the [[Reformation]], individuals such as [[Martin Luther]] strongly criticized the claims of papal primacy within the {{lang|la|Decretum}}.<ref>{{Cite book |last=Luther |first=Martin |url=https://books.google.com/books?id=_h-OIPKasccC |title=Dris Martini Lutheri Colloquia Mensalia<!--the rest is superfluous: Or, Dr Martin Luther's Divine Discourses at His Table, &c: Which in His Life Time Hee Held with Divers Learned Men (such as Were Philip Melancthon, Casparus Cruciger, Justus Jonas, Paulus Eberus, Vitus Dietericus, Joannes Bugenhagen Joannes Forsterus, and Others) Conteining Questions and Answers Touching Religion, and Other Main Points of Doctrine, as Also Many Notable Histories, and All Sorts of Learning, Comforts, Advises, Prophesies, Admonitions, Directions and Instructions.

== Sources ==
Gratian's sources were Roman law, the [[Bible]], the writings of (or attributed to) the [[Church Fathers]], [[papal decretal]]s, the acts of [[ecumenical council|church councils]] and [[synod]]s. In most cases, Gratian obtained the material not from a direct reading of the sources but rather through intermediate collections. Thanks to the research of modern scholars (in particular Charles Munier, Titus Lenherr, and Peter Landau) it is now known that Gratian made use of a relatively-small number of collections in the composition of most of the {{lang|la|Decretum}}:

*[[Anselm of Lucca|Anselm (II) of Lucca]]'s canonical collection, originally compiled around 1083 and existing in four main recensions: A, B, Bb, and C. Peter Landau suggests that Gratian probably employed a manuscript containing an expanded form of recension A which he calls recension A’;
*the {{lang|la|Collectio tripartita}} attributed to [[Ivo of Chartres]], usually thought to date to 1095;
*the {{lang|la|Panormia}} of [[Ivo of Chartres]], also usually dated to 1095, although several scholars have argued for a later date and some even question Ivo's authorship;
*[[Gregory of St. Grisogono]]'s {{lang|la|Polycarpus}}, completed some time after 1111;
*the {{lang|la|Collectio canonum trium librorum}} (Collection in Three Books), inspired by the doctrines of [[Paschal II]] and the reform of the Church, composed in [[Italy]] (probably in [[Pistoia]], [[Tuscany]], by an anonymous Roman canonist) between 1111 and 1123<ref name="Wei_2016">{{cite book|title= Gratian the Theologian|last= Wei|first= John C.|year= 2016|publisher= The Catholic University of America Press|location= Washington D.C.|isbn= 978-0-8132-2803-7|page= 22}}</ref> or 1124;<ref name="Jaser_2013">{{cite book|title= Ecclesia maledicens|last= Jaser|first= Christian|year= 2013|publisher= Mohr Siebeck|location= Tübingen|isbn= 978-3-16-151927-7|page= 279}}</ref>
*the {{lang|la|[[Lex Romana Visigothorum]]}};
*secular texts such as [[Plato]];
*the {{lang|la|Glossa ordinaria}} to the Bible.

Other sources are known to have been used in the composition of particular sections of the {{lang|la|Decretum}}:
*[[Isidore of Seville]]'s ''Etymologies'' for DD. 1-9 (the so-called ''Treatise on Laws'');
*[[Alger of Liège]]'s {{lang|la|Liber de misericordia et iustitia}} for C. 1;
*the {{lang|la|Sententiae magistri A.}} for the {{lang|la|De penitentia}} and some other sections.

Gratian himself named his work {{lang|la|Concordia Discordantium Canonum}} – "Concord of Discordant Canons". The name is fitting: Gratian tried to harmonize apparently contradictory canons with each other, by discussing different interpretations and deciding on a solution, as a judge in a case. This [[dialectic]]al approach allowed for other law professors to work with the {{lang|la|Decretum}} and to develop their own solutions and commentaries. These [[legist]]s are known as the [[decretist]]s.

{{blockquote|...&nbsp;the ''Concordance of Discordant Canons'' or {{lang|la|Decretum}} served the function of giving the canonists a text like that of the {{lang|la|[[Corpus Iuris Civilis]]}} for the civilians or the bible for the theologians.<ref>Donahue, Jr., ''A Crisis of Law?'', pg. 16.</ref>}}

These commentaries were called [[Gloss (annotation)|glosses]]. Editions printed in the 15th, 16th or 17th century frequently included the glosses along with the text. Collections of glosses were called "gloss apparatus" or {{lang|la|Lectura in Decretum}} (see also [[glossator]]). Systematic commentaries were called {{lang|la|Summae}}. Some of these {{lang|la|Summae}} were soon in circulation as well and obtained the same level of fame as the {{lang|la|Decretum}} itself. Early commentators included [[Paucapalea]] and [[Magister Rolandus]]. The most important commentators were probably [[Rufinus (decretist)|Rufin of Bologna]] (died before 1192) and [[Huguccio]] (died 1210). Less well-known was the commentary of [[Simon of Bisignano]], which consisted of the ''Glosses on the {{lang|la|Decretum}}'' and the {{lang|la|Summa Simonis}}.

Because of its influence as a source of canon law, the {{lang|la|Decretum}} served as an influence for 12th-century jurists in the development of Western legal systems and their rules of evidence, which in canon law (including in the Decretum) did not include trial by ordeal and by battle.<ref name="Woods_2005">{{cite book |title=How the Catholic Church Built Western Civilization |last=Woods |first=Thomas E. |year=2005 |publisher=Regency |location=Washington, DC |isbn=0-89526-038-7 |url-access=registration |url=https://archive.org/details/howcatholicchurc0000wood}}</ref>

The author Thomas Woods called the {{lang|la|Decretum}} "the first comprehensive and systematic legal treatise in the history of the West, and perhaps in the history of mankind – if by 'comprehensive' is meant the attempt to embrace virtually the entire law of a given polity, and if by 'systematic' is meant the express effort to codify that law as a single body, in which all parts are viewed as interacting to form a whole." The {{lang|la|Decretum}} made a direct contribution to the development of Western law in areas that it dealt with such as marriage, property and inheritance. Specific concepts preferred included consent for marriage, and wrongful intent in determining whether a certain act constituted a crime.<ref name="Woods_2005"/> The [[Corpus Juris Civilis]] and [[Digest (Roman law)|Digesta]] were 'comprehensive' and preceded it, and so did the 'systematic' [[Institutes (Gaius)|Institutes]] but covered only '[[private law]]'.
