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, Nicaea I

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

The latter was long held in esteem and passed into the Russian Church, but it was by degrees supplanted by the "Nomocanon of Photios I of Constantinople, 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.

and common law (legal system), common law bear the influences of canon law.
Much of the legislative style was adapted from that of Roman Law especially the Justinian I, 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 Rule according to higher law, higher law of ultimate justice, over and above the momentary law of the state.

Canonists have formulated interpretive Regulæ Juris, rules of law for the magisterial (non-legislatorial) Interpretation (Catholic canon law), interpretation of canonical 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 Aristotelianism, Aristotelian-Treatise on Law, Thomistic philosophy of law, legal philosophy,[ Thomas Aquinas never explicitly discusses the place of canon law in his ''Treatise on Law'' However, Aquinas himself was influenced by canon law. While many canonists apply the Treatise on Law, Thomistic definition of law (''lex'') to canon law without objection, some authors dispute the applicability of the Thomism, Thomistic definition to canon law, arguing that its application would impoverish ecclesiology (Catholic Church), ecclesiology and corrupt the very supernatural end of canon law.

The Second Ecumenical Council of the Vatican, commonly known as the , or , was the 21st ecumenical 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 justice, juridical in the Catholic Church, Church of Jesus Christ." The discipline seeks to better explain the nature of law in the church and engages in theological discussions in post-Vatican II, conciliar Catholicism and seeks to combat "postconciliar antijuridicism".

Canonistics, faculties, and institutes
The academic degrees in canon law are the J.C.B. (''Iuris Canonici Baccalaureatus'', Bachelor of Canon Law, normally taken as a graduate degree), J.C.L. (''Iuris Canonici Licentiatus'', Licentiate of Canon Law) and the J.C.D. (''Iuris Canonici Doctor'', Doctor of Canon Law), and those with a J.C.L. or higher are usually called "canonists" or "canon lawyers". Because of its specialized nature, advanced degrees in civil law or theology are normal prerequisites for the study of canon law. Canon law as a field is called Canonistics.
