Prospero Fagnani (born in Italy, place and date of birth uncertain; died 1678) was an Italian canon lawyer. Some writers place his birth in 1598, others in 1587 or in 1588.
It is certain that he studied at Perugia. At the age of twenty he was a doctor of civil and canon law; at twenty-two, secretary of the Congregation of the Council. He held this office for fifteen years. He fulfilled the same functions in several other Roman Congregations. It is not certain that he ever lectured on canon law at the Roman University (Sapienza).
He became blind at the age of forty-four. This affliction did not prevent him from devoting himself to canonical studies and from writing a commentary of the Decretals of Gregory IX, which gained for him the title of "Doctor Caecus Oculatissimus", i.e. the blind yet most far-sighted doctor. This commentary includes interpretations of the texts of the most difficult of the Decretals of Gregory IX. It is distinguished by the clearness with which the most complex and disputed questions of canon law are explained. The work is also of value for the purpose of ascertaining the practice of the Roman Congregations, especially that of the Congregation of the Council, of which the author quotes numerous decisions.
Pope Benedict XIV gave this work the highest praise, and its authority is still continually appealed to in the Roman Congregations. It is divided, like the Decretals of Gregory IX, into five books. The first edition was published at Rome, in 1661, under the title of "Jus canonicum seu commentaria absolutissima in quinque libros Decretalium". It has been reprinted several times.
Fagnani is reproached with excessive rigour in his commentary on the chapter of the Decretals "Ne innitaris" (Book I, De constitutionibus), in which he combats the doctrine of probabilism. Saint Alphonsus calls him "magnus rigoristarum princeps", the great prince of the rigorists (Homo apostolicus, Tract. I, no. 63; Theologia Moralis, IV, no. 669).
Giovanni d'Andrea or Johannes Andreæ was an Italian expert in canon law, the most renowned and successful canonist of the later Middle Ages. 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.
Simony is the act of selling church offices and roles or sacred things. It is named after Simon Magus, who is described in the Acts of the Apostles as having offered two disciples of Jesus payment in exchange for their empowering him to impart the power of the Holy Spirit to anyone on whom he would place his hands. The term extends to other forms of trafficking for money in "spiritual things".
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 legal system in the West, while the unique traditions of Eastern Catholic canon law govern the 23 Eastern Catholic particular churches sui iuris.
Gerard la Pucelle was a peripatetic Anglo-French scholar of canon law, clerk, and Bishop of Coventry.
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. In 1990, Eastern Catholic canon law was codified in the Code of Canons of the Eastern Churches, which is currently in effect for the Eastern Catholic Churches.
Dominium mundi is an idea of universal dominion developed in the Middle Ages. Inspired by the memory of the Roman Empire, dominium mundi implied the recognition of one supreme authority, which generated a prolonged political and spiritual struggle between imperial and ecclesiastical power. This struggle can be said to have begun with the Investiture Controversy, and was mainly embodied by the Holy Roman Empire and Catholic Church, which elevated the emperor and Pope, respectively, to the status of supreme ruler. The idea of universal dominion divided Italy into the warring faction of Guelphs and Ghibellines. Guelphs supported the Church, while the Ghibellines supported the Empire. After two hundred years of division during the 12th and 13th centuries, neither one of the powers had prevailed, due to their mutual dependency and the rise of the powerful and practically independent reigns of Church and the State. The idea of dominium mundi did not reappear in its original form, despite the fact that both universal powers subsisted.
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.
The Decretals of Gregory IX, also collectively called the Liber extra, are a source of medieval Catholic canon law. In 1230, Pope Gregory IX ordered his chaplain and confessor, St. Raymond of Penyafort, a Dominican, to form a new canonical collection destined to replace the Decretum Gratiani, which was the chief collection of legal writings for the church for over 90 years. It has been said that the pope used these letters to emphasize his power over the Universal Church.
Francesco Lorenzo Brancati di Lauria was an Italian cardinal and theologian.
The Liber Septimus may refer to one of three canonical 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.
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 legal history of the Catholic Church is the history of 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 Collectiones canonum Dionysianae, also known as Collectio Dionysiana or Dionysiana Collectio, are the several collections of ancient canons prepared by a Scythian monk, Dionysius 'the humble' (exiguus). They include the Collectio conciliorum Dionysiana I, the Collectio conciliorum Dionysiana II, and the Collectio decretalium Dionysiana. They are of the utmost importance for the development of the canon law tradition in the West.
In Catholic canon law, the canon law of contract follows that of the civil jurisdiction in which Catholic canon law operates.
