Overview

In the first half of the 12th century Gratian, ''clusinus episcopus'',Reali, Francesco (ed.), Graziano da Chiusi e la sua opera, 2009, pg. 63-73 and pg. 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 '' Augusti IIII idus Obiit .... ''): '' 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 "Gratianus clusinus episcopus" ('' Robertus de Monte '', Cronica, Bethman d., MGH Scriptores VI, Hannoverae 1844, p. 490) and that other sources of the twelfth and thirteenth centuries also speak of Gratian as bishop or as bishop of Chiusi. probably a jurist of the ecclesiastical forum and a teacher, ''rubricator'' at the monastery of Saints Nabor and Felix (according to the Bolognese Odofredus Denariis 3th century and starting from the 18th century believed to have been a

monk, composed the work he called ''Concordia discordantium canonum'', and others titled ''Nova collectio, Decreta, Corpus juris canonici'', or the more commonly accepted name, ''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 (''theologia practica externa''), i.e., the study and the forensic use of canon law. In spite of its great reputation and wide diffusion, the ''Decretum'' has never been recognized by the Church as an official collection. The so-called ''vulgata'' or vulgate version (an advanced editorial stage) of the ''Decretum'' is divided into three parts (''ministeria, negotia, sacramenta''). * The first part is divided into 101 distinctions (''distinctiones''), the first 20 of which form an introduction to the general principles of canon Law (''tractatus decretalium''); the remainder constitutes a ''tractatus ordinandorum'', relative to ecclesiastical persons and function. * The second part contains 36 causes (''causæ''), divided into questions (''quæstiones''), and treat of ecclesiastical administration, procedural issues and marriage. ''Quaestio'' 3 of ''Causa'' 33 on penance (''De penitentia'') is treated separately and subdivided into 7 distinctions. * The third part ''De consecratione'' deals with sacramental and liturgical law and contains 5 distinctions. Each distinction or question contains ''dicta Gratiani'', or maxims of Gratian, and ''canones''. Gratian himself raises questions and brings forward difficulties, which he answers by quoting ''auctoritates'', i. e. canons of councils, decretals of the popes, texts of the Scripture or of the Fathers. These are the ''canones''; the entire remaining portion, even the summaries of the canons and the chronological indications, are called the maxims or ''dicta Gratiani''. Many ''auctoritates'' have been inserted in the ''Decretum'' by authors of a later date. These are the ''Paleae'', so called from Paucapalea, the name of the principal commentator on the ''Decretum''. The Roman revisers of the 16th century (1566–82) corrected the text of the "Decree" and added many critical notes designated by the words ''Correctores Romani''.


Citing the ''Decretum''

The ''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 ''Causa'' 33, ''quaestio'' 3 of the second part are referred to as ''De penitentia'' (or ''De pen.''), while the distinctions of the third part are referred to as ''De consecratione'' (or ''De cons.''). The Part is usually not included, as the citation form is different for each. Citation styles for the ''Decretum'' have changed over time and can generally be categorised under the modern, obsolescent, and obsolete forms.


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 ''dicta'' are referred to with a lowercase "d. a. c." (''dictum ante canonem'', for commentary preceding the canon) or "d. p. c." (''dictum post canonem'', for commentary following the canon). Examples: *
art I Art is a diverse range of human activity, and resulting product, that involves creative or imaginative talent expressive of technical proficiency, beauty, emotional power, or conceptual ideas. There is no generally agreed definition of what ...
D. 23 c.7 * art IIC. 15 q. 2 c. 4 * art IIC. 23 q. 8 d. p. c. 25 * art II, ''De penitentia''D. 3 de pen. c. 24 *
art III Art is a diverse range of human activity, and resulting product, that involves creative or imaginative talent expressive of technical proficiency, beauty, emotional power, or conceptual ideas. There is no generally agreed definition of wha ...
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 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 (''Distinctio, Causa, quaestio'') were cited with (usually Roman) numerals. Since the numbering of the ''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. ''In Christo ii''. Examples (using the same references as above): * ''xxiii dist. episcopus'' * ''xv q. ii felix'' * ''xxiii q. viii § hinc datur'' * ''iii de pen tentiatotam'' * ''ii de cons. In Christo ii'' Early commentators might also refer to the first few canons by number (e.g. ''cap. iij'' for the third canon of a distinction), or to the last few canons as ''cap. antepenult.'' ("capitulum antepenultimum," that is, third to last), ''cap. penult.'' (or ''pen.'' or ''pe.'', second to last), and ''cap. fin.'' ("capitulum finale") or ''cap. ult.'' (last).

'' 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 ''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

, 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.Reali, Francesco, ''Alle origini del diritto civile europeo'', in ''Studia Gratiana'' 30 (2020), 27-114 Gratian's work was an attempt, using early 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

, and secular law in his efforts to reconcile the canons. Gratian found a place in Dante's ''Paradise'' among the doctors of the Church: He has long been acclaimed as ''Pater Juris Canonici'' ( Latin, "Father of Canon Law"), a title he shares with his successor St. Raymond of Penyafort. Gratian was the father and the first teacher of the ''scientia nova'' which he himself coined: the new canon law or "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. With later commentaries and supplements, the work was incorporated into the ''

''. The ''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 ''Codex Juris Canonici'' of 1917 put it out of use.Crompton (2006):174 As late as 1997, scholars commonly set the date of completion at 1140, but this accuracy in dating isn't possible after Anders Winroth's groundbreaking scholarship. Research by Anders Winroth shows that the ''Decretum'' existed in two published recensions. 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 ''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. However, Winroth's thesis of two Gratians remains controversial. 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, ''Stiftsbibliothek'', 673 (=Sg), which some have argued contains the earliest known draft (Larrainzar's ''borrador'') of the ''Decretum'', but which other scholars have argued contains an abbreviation of the first recension expanded with texts taken from the second recension.


Criticism

During the reformation, individuals such as Martin Luther strongly criticized the claims of papal primacy within the Decretals One of Luther's chief concern surrounded Distinctio 40 (Chapter "Si papa") which read: ''"If the pope fails, and neglects fraternal salvation, if he is found useless, and remiss in his works, and moreover silent from good, which offends him more, and nevertheless leads countless peoples with him as the first slave of hell, with himself to be scourged with many plagues for eternity. No mortal may presume to rebuke the sins of this man, because he himself is to judge all".'' Additional concerns about papal primacy in the context of 2 Thessalonians 2:4 were raised regarding Distinctio 96 chapter 7 which read: ''“It is quite clearly shown that the pontiff cannot be bound by the secular power, which is evidently called a god by the pious prince Constantine, since it is clear that even god cannot be judged by men”'' Protestants also took concern with the assertion that the pope had the authority to change divine law. Comparisons were made between the little horn of Daniel 7:25 and the pope's claim of ability to change divine law as seen in Lib III of Gratian's Liber Extra with the statement: ''"for He

Effect

Gratian himself named his work ''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 dialectical approach allowed for other law professors to work with the ''Decretum'' and to develop their own solutions and commentaries. These

s are known as the decretists. These commentaries were called 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 ''Lectura in Decretum'' (see also glossator). Systematic commentaries were called ''Summae''. Some of these ''Summae'' were soon in circulation as well and obtained the same level of fame as the ''Decretum'' itself. Early commentators included Paucapalea and Magister Rolandus. The most important commentators were probably Rufin of Bologna (died before 1192) and Huguccio (died 1210). Less well-known was the commentary of

Importance to Western law

The ''Decretum'' served as a model for 12th-century jurists in the formation of Western law, based on rational rules and evidence to replace barbaric laws which often involved trial by ordeal or battle. The ''Decretum'' has been called "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 ''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 included consent for marriage, and wrongful intent in determining whether a certain act constituted a crime.
