The canon law of the Catholic Church has all the ordinary elements of a mature legal system: laws, courts, lawyers, judges.

Definitions

The term "canon law" (''ius canonicum'') was only regularly used from the twelfth century onwards.Berman, ''Law and Revolution'', pg. 202. The term ''ius ecclesiasticum'', by contrast, referred to the secular law, whether imperial, royal, or feudal, that dealt with relations between the state and the Catholic Church. The term '' corpus iuris canonici'' was used to denote canon law as legal system beginning in the thirteenth century. Other terms sometimes used synonymously with ''ius canonicum'' include ''ius sacrum'', ''ius ecclesiasticum'', ''ius divinum'', and ''ius pontificium'', as well as ''sacri canones'' (sacred canons). is the

James Socias (gen. edit.), ''Our Moral Life in Christ''. (Chicago: Midwest Theological Forum, 2003), 84. Fernando della Rocca used the term "ecclesiastical-positive law" in contradistinction to ''civil''-positive law, in order to differentiate between the human legislators of church and state, all of which issue "positive law" in the normal sense. Examples of ecclesiastical positive law are fasting during the liturgical season of

Etymology of "canon"

The word "canon" comes from the Greek ''kanon'', which in its original usage denoted a straight rod, was later used for a measuring stick, and eventually came to mean a rule or norm.Berman, ''Law and Revolution'', pg. 199 In 325, when the first ecumenical council,

Sources of canon law

The term source or fountain of canon law (''fons iuris canonici'') may be taken in a twofold sense: a) as the formal cause of the existence of a law, and in this sense, we speak of the ''fontes essendi'' ( Latin: "sources of being") of canon law or lawgivers; b) as the material channel through which laws are handed down and made known, and in this sense the sources are styled ''fontes cognoscendi'' ( Latin: "sources of knowing"), or depositaries, like sources of history.A COMMENTARY ON THE NEW CODE OF CANON LAW

The Eastern Catholic canon law of the Eastern Catholic Churches, which had developed some different disciplines and practices, underwent its own process of codification, resulting in the '' Codex Canonum Ecclesiarum Orientalium'' promulgated in 1990 by Pope John Paul II.

''Ius antiquum''

The period of canonical history known as the ''ius antiquum'' ("ancient law") extends from the foundation of the Church to the time of Gratian (mid-12th century).Wigmore, ''Panorama'', p. 951 This period can be further divided into three periods: the time of the apostles to the death of

" councils (the Emperor summoning all of the known world's bishops to attend with at least the acknowledgement of the Bishop of Rome) or "local" councils (bishops of a region or territory). Over time, these canons were supplemented with decretals of the Bishops of Rome, which were responses to doubts or problems according to the maxim, "''Roma locuta est, causa finita est''" ("Rome has spoken, the case is closed"). A common misconception, the Catholic Encyclopedia links this saying to St Augustine who actually said something quite different: "''jam enim de hac causa duo concilia missa sunt ad sedem apostolicam; inde etiam rescripta venerunt; causa finita est''" (which roughly translate to: "there are two councils, for now, this matter as brought to the Apostolic See, whence also letters are come to pass, the case was finished") in response to the heretical Pelagianism of the time. In the first millennium of the Roman Church, the canons of various ecumenical and local councils were supplemented with decretals of the popes; these were gathered together into collections.


''Ius novum''

The period of canonical history known as the ''Ius novum'' ("new law") or ''middle period'' covers the time from Gratian to the Council of Trent (mid-12th century–16th century). The spurious conciliar canons and papal decrees were gathered together into collections, both unofficial and official. In the year 1000, there was no book that had attempted to summarize the whole body of canon law, to systematize it in whole or in part. The first truly systematic collection was assembled by the

In the thirteenth century, the Roman Church began to collect and organize its canon law, which after a millennium of development had become a complex and difficult system of interpretation and cross-referencing.

''Ius codicis''

The fourth period of canonical history is that of the present day, initiated by the promulgation of the 1917 Code of Canon Law on 27 May 1917. Benedict XV, in his bull of promulgation, refers to the ''motu proprio'' ''Arduum sane'', which was issued by Pius X, March 17, 1904, and gave rise to the 1917 Code. In that memorable pronouncement the late Pontiff stated the reasons which prompted him as the supreme Pastor of souls, who has the care of all the churches, to provide for a new codification of ecclesiastic laws, with a view " to put together with order and clearness all the laws of the Church thus far issued, removing all those that would be recognized as abrogated or obsolete, adapting others to the necessities of the times, and enacting new ones in conformity with the present needs." It is sometimes referred to as the ''ius codicis'' ("law of the code") or, in comparison with all law before it, the ''ius novum'' ("new law"). From time to time, the Pontifical Council for Legislative Texts issues authentic interpretations regarding the code. The pope occasionally amends the text of the codes.


Pio-Benedictine law

By the 19th century, the body of canonical legislation included some 10,000 norms. Many of these were difficult to reconcile with one another due to changes in circumstances and practice. The situation impelled
Pope Pius X Pope Pius X ( it, Pio X; born Giuseppe Melchiorre Sarto; 2 June 1835 – 20 August 1914) was head of the Catholic Church from 4 August 1903 to his death in August 1914. Pius X is known for vigorously opposing modernist interpretations of C ...
to order the creation of the first Code of Canon Law, a single volume of clearly stated laws. Under the aegis of the Cardinal Pietro Gasparri, the Commission for the Codification of Canon Law was completed under Benedict XV, who promulgated the Code on 27 May 1917,De Meester, ''Compendium'' Tomus Primus, p. 52 effective on 29 May 1918. The work having been begun by Pius X, it was sometimes called the "Pio-Benedictine Code" but more often the 1917 Code to distinguish it from the later 1983 Code which replaced it. In its preparation, centuries of material was examined, scrutinized for authenticity by leading experts, and harmonized as much as possible with opposing canons and even other codes, from the Code of Justinian to the Napoleonic Code.


Johanno-Pauline law

In the succeeding decades, some parts of the 1917 ''Code'' were retouched, especially under
Pope Pius XII Pope Pius XII ( it, Pio XII), born Eugenio Maria Giuseppe Giovanni Pacelli (; 2 March 18769 October 1958), was head of the Catholic Church and sovereign of the Vatican City State from 2 March 1939 until his death in October 1958. Before his e ...
. In 1959, Pope John XXIII announced, together with his intention to call the Second Vatican Council, that the 1917 ''Code'' would be completely revised. In 1963, the commission appointed to undertake the task decided to delay the project until the council had been concluded. After Vatican II closed in 1965, it became apparent that the 1917 ''Code'' would need to be revised in light of the documents and theology of Vatican II. When work finally began, almost two decades of study and discussion on drafts of the various sections were needed before Pope John Paul II could promulgate the revised edition, which came into force on 27 November 1983, having been promulgated via the apostolic constitution '' Sacrae Disciplinae Leges'' of 25 January 1983. Containing 1752 canons, it is the law currently binding on the Latin Church. This codification is referred to as the 1983 ''Code of Canon Law'' to distinguish it from the 1917 ''Code''. Like the preceding codification, it applies to Roman Catholics of the Latin Church. As the currently-in-force law for the Latin Church, it constitutes a major part of the ''Ius vigens'' ( Latin: "active law").

'' particular Eastern Catholic Church. Originating with the canons of particular councils and the writings of the Eastern Church Fathers, oriental canon law developed in concert with Byzantine Roman laws, leading to the compilation of nomocanons. Oriental canon law is distinguished from Latin canon law, which developed along a separate line in the remnants of the Western Roman Empire under the direct influence of the Roman Pontiff, and is now chiefly codified in the 1983 ''Code of Canon Law''.


Nomocanons

A nomocanon (nomokanon) is a collection of

, consisting of the elements from both the civil law (nomoi) and the canon law (kanones). Collections of this kind were found only in Eastern law. The Greek Church has two principal nomocanonical collections, the "Nomocanon of John Scholasticus" of the sixth century and the "Nomocanon in 14 titles", which dates from the reign of the Byzantine Emperor Heraclius (), made by fusion of the ''Collectio tripartita'' (collection of Justinian's imperial law) and "Canonic syntagma" (ecclesiastical canons). The latter was long held in esteem and passed into the Russian Church, but it was by degrees supplanted by the "Nomocanon of Photios" in 883. Photius compiled systematically the canons of the East which amount to a counterpart of Gratian in the West. His 2-part collection, a chronological collection of synodal canons and his nomocanon revision with updated civil laws, became a classical source of ancient canon law for the Greek Church.

These parts were revised as part of the application of Pope John XXIII's decision to carry out a general revision of the Church's canon law; as a result, a distinct Code for members of the Eastern Catholic Churches came into effect for the first time on 1 October 1991 ( Apostolic Constitution ''Sacri Canones'' of 18 October 1990).

Jurisprudence of canon law

The institutions and practices of canon law paralleled the legal development of much of Europe, and consequently both modern civil law and common law bear the influences of canon law. Much of the legislative style was adapted from that of Roman Law especially the Justinianic '' Corpus Iuris Civilis''. After the 'fall' of the Roman Empire and up until the revival of Roman Law in the 11th century canon law served as the most important unifying force among the local systems in the Civil Law tradition. The Catholic Church developed the inquisitorial system in the Middle Ages. The canonists introduced into post-Roman Europe the concept of a higher law of ultimate justice, over and above the momentary law of the state. The primary canonical sources of law are the 1983 ''Code of Canon Law'',Dr. Edward Peters

the ''Code of Canons of the Eastern Churches'', and '' Pastor Bonus.'' Other sources include apostolic constitutions, ''motibus propriis'', particular law, and—with the approbation of the competent legislator— custom. A law must be promulgated for it to have legal effect. A later and contrary law obrogates an earlier law. Canonists have formulated interpretive rules of law for the magisterial (non-legislatorial) interpretation of canon laws. An authentic interpretation is an official interpretation of a law issued by the law's legislator, and has the force of law.


Philosophy, theology, and fundamental theory of Catholic canon law

Although canonical jurisprudential theory generally follows the principles of Aristotelian- Thomistic legal philosophy, Thomas Aquinas never explicitly discusses the place of canon law in his ''
Treatise on Law ''Treatise on Law'' is Thomas Aquinas' major work of legal philosophy. It forms questions 90–108 of the ''Prima Secundæ'' ("First artof the Second art) of the ''Summa Theologiæ'', Aquinas' masterwork of Scholastic philosophical theology. ...
'' However, Aquinas himself was influenced by canon law. While many canonists apply the Thomistic definition of law (''lex'') to canon law without objection, some authors dispute the applicability of the Thomistic definition to canon law, arguing that its application would impoverish ecclesiology and corrupt the very supernatural end of canon law. In the decades following the Second Vatican Council, many canonists called for a more theological, rather than philosophical, conception of canon law,Errázuriz, "Justice in the Church", pg. 71 acknowledging the "triple relationship between theology, philosophy, and canon law". Some authors conceive of canon law as ''essentially'' theological and the discipline of canon law as a theological subdiscipline, but Msgr. Carlos José Errázuriz contends that "in a certain sense, all postconciliar canonical scholarship has shown a theological concern in the widest sense, that is, a tendency to determine more clearly the place of the juridical in the mystery of the Church." The fundamental theory of canon law is a discipline covering the basis of canon law in the very nature of the church. Fundamental theory is a newer discipline that takes as is object "the existence and nature of what is
