Giovanni d'Andrea or Johannes Andreæ was an Italian expert in canon law. His contemporaries referred to him as iuris canonici fons et tuba. Most important among his works were extensive commentaries on all of the official collections of papal decretals, papal judgments in the form of letters to delegated judges that were at the core of canon law.
Pope Gregory IX was head of the Catholic Church and the ruler of the Papal States from 19 March 1227 until his death in 1241. He is known for issuing the Decretales and instituting the Papal Inquisition, in response to the failures of the episcopal inquisitions established during the time of Pope Lucius III, by means of the papal bull Ad abolendam, issued in 1184.
Decretals are letters of a pope that formulate decisions in ecclesiastical law of the Catholic Church.
The Decretum Gratiani, also known as the Concordia discordantium canonum or Concordantia discordantium canonum or simply as the Decretum, is a collection of 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 Corpus Juris Canonici. It was used as the main source of law by canonists of the Roman Catholic Church until the Decretals, promulgated by Pope Gregory IX in 1234, obtained legal force, after which it was the cornerstone of the Corpus Juris Canonici, in force until 1917.
Raymond of Penyafort was a Catalan Dominican friar in the 13th century, who compiled the Decretals of Gregory IX, a collection of canonical laws that remained a major part of Church law until the 1917 Code of Canon Law abrogated it. He is honored as a saint in the Catholic Church and is the patron saint of canon lawyers.
Huguccio was an Italian canon lawyer.
The canon law of the Catholic Church is "how the Church organizes and governs herself". It is the system of laws and ecclesiastical legal principles made and enforced by the hierarchical authorities of the Catholic Church to regulate its external organization and government and to order and direct the activities of Catholics toward the mission of the Church. It was the first modern Western legal system and is the oldest continuously functioning system of law in the West, while the unique traditions of Eastern Catholic canon law govern the 23 Eastern Catholic particular churches sui iuris.
In the history of canon law, a decretist was a student and interpreter of the Decretum Gratiani. Like Gratian, the decretists sought to provide "a harmony of discordant canons", and they worked towards this through glosses (glossae) and summaries (summae) on Gratian. They are contrasted with the decretalists, whose work primarily focused on papal decretals.
The Corpus Juris Canonici is a collection of significant sources of the Canon law of the Catholic Church that was applicable to the Latin Church. It was replaced by the 1917 Code of Canon Law which went into effect in 1918. The 1917 Code was later replaced by the 1983 Code of Canon Law, the codification of canon law currently in effect for the Latin Church.
Collections of ancient canons contain collected bodies of canon law that originated in various documents, such as papal and synodal decisions, and that can be designated by the generic term of canons.
Bernard of Botone was a noted Italian canonist of the thirteenth century. He is generally called Bern(h)ardus Parmensis or Bernard of Parma, from his birthplace Parma.
Guido de Baysio was an Italian canonist. Having held the position of archdeacon, Baysio is often known by the name Archidiaconus and thus quoted.
The Liber Septimus may refer to one of three Catholic canon law collections of quite different value from a legal standpoint which are known by this title.
The term Extravagantes is applied to the canon law of the Roman Catholic Church, to designate some papal decretals not contained in certain canonical collections which possess a special authority. More precisely, they are not found in Gratian's Decretum or the three official collections of the Corpus Juris Canonici.
The 1917 Code of Canon Law, also referred to as the Pio-Benedictine Code, is the first official comprehensive codification of Latin canon law.
In the history of canon law, the decretalists of the thirteenth century formed a school of interpretation that emphasised the decretals, those letters issued by the Popes ruling on matters of church discipline, in preference to the Decretum Gratiani (1141), which their rivals, the decretists, favoured. The decretalists were early compilers of the papal decretals, and their work, such as that of Simon of Bisignano, was used by the dominant decretist school.
Margaritae are collections of canon law and decretals.
Jus antiquum is a period in the legal history of the Catholic Church, spanning from the beginning of the church to the Decretum of Gratian, i.e. from A.D. 33 to around 1150. In the first 10 centuries of the church, there was a great proliferation of canonical collections, mostly assembled by private individuals and not by church authority as such.
The Catholic Church utilizes the oldest continuously functioning legal system in the West, much later than Roman law but predating the evolution of modern European civil law traditions. The history of Latin canon law can be divided into four periods: the jus antiquum, the jus novum, the jus novissimum and the Code of Canon Law. In relation to the Code, history can be divided into the jus vetus and the jus novum. Eastern canon law developed separately.
The Quinque compilationes antiquae is a set of five collections of twelfth and thirteenth century decretals totalling between 1,971 and 2,139 chapters.
