The First Council of the Lateran was the 9th ecumenical council recognized by the Catholic Church. It was convoked by Pope Callixtus II in December 1122, immediately after the Concordat of Worms. The council sought to bring an end to the practice of the conferring of ecclesiastical benefices by people who were laymen, free the election of bishops and abbots from secular influence, clarify the separation of spiritual and temporal affairs, re-establish the principle that spiritual authority resides solely in the Church and abolish the claim of the Holy Roman Emperor to influence papal elections.
Ultramontanism is a clerical political conception within the Catholic Church that places strong emphasis on the prerogatives and powers of the Pope. It contrasts with Gallicanism, the belief that popular civil authority—often represented by the monarch's or state's authority—over the Church is comparable to that of the Pope.
The Avignon Papacy was the period from 1309 to 1376 during which seven successive popes resided in Avignon rather than in Rome. The situation arose from the conflict between the papacy and the French crown, culminating in the death of Pope Boniface VIII after his arrest and maltreatment by Philip IV of France. Following the subsequent death of Pope Benedict XI, Philip forced a deadlocked conclave to elect the French Clement V as pope in 1305. Clement refused to move to Rome, and in 1309 he moved his court to the papal enclave at Avignon, where it remained for the next 67 years. This absence from Rome is sometimes referred to as the "Babylonian captivity of the Papacy".
The Holy See exercised political and secular influence, as distinguished from its spiritual and pastoral activity, while the pope ruled the Papal States in central Italy.
The Council of Florence is the seventeenth ecumenical council recognized by the Catholic Church, held between 1431 and 1449. It was convoked as the Council of Basel by Pope Martin V shortly before his death in February 1431 and took place in the context of the Hussite Wars in Bohemia and the rise of the Ottoman Empire. At stake was the greater conflict between the conciliar movement and the principle of papal supremacy.
In English history, praemunire or praemunire facias refers to a 14th-century law that prohibited the assertion or maintenance of papal jurisdiction, or any other foreign jurisdiction or claim of supremacy in England, against the supremacy of the monarch. This law was enforced by the writ of praemunire facias, a writ of summons from which the law takes its name.
Clericis laicos was a papal bull issued on February 5, 1296 by Pope Boniface VIII in an attempt to prevent the secular states of Europe, in particular France and England, from appropriating church revenues without the express prior permission of the pope. The two expansionist monarchies had come to blows, and the precedents for taxation of the clergy for a "just war" if it was declared a crusade and authorized by the papacy had been well established. The position of Boniface was that prior authorization had always been required and that the clergy had not been taxed for purely secular and dynastic warfare.
Gallicanism is the belief that popular civil authority—often represented by the monarch's or the state's authority—over the Catholic Church is comparable to that of the pope. Gallicanism is a rejection of ultramontanism; it has something in common with Anglicanism, but is nuanced, in that it plays down the authority of the Pope in church without denying that there are some authoritative elements to the office associated with being primus inter pares. Other terms for the same or similar doctrines include Erastianism, Febronianism, and Josephinism.
The Gregorian Reforms were a series of reforms initiated by Pope Gregory VII and the circle he formed in the papal curia, c. 1050–80, which dealt with the moral integrity and independence of the clergy. The reforms are considered to be named after Pope Gregory VII (1073–85), though he personally denied it and claimed his reforms, like his regnal name, honoured Pope Gregory I.
Unam sanctam is a papal bull that was issued by Pope Boniface VIII on 18 November 1302. It laid down dogmatic propositions on the unity of the Catholic Church, the necessity of belonging to it for eternal salvation, the position of the Pope as supreme head of the Church and the duty thence arising of submission to the Pope in order to belong to the Church and thus to attain salvation. The Pope further emphasized the higher position of the spiritual in comparison with the secular order. The historian Brian Tierney calls it "probably the most famous" document on church and state in medieval Europe. The original document is lost, but a version of the text can be found in the registers of Boniface VIII in the Vatican Archives. The bull was the definitive statement of the late medieval theory of hierocracy, which argued for the temporal as well as spiritual supremacy of the pope.
Conciliarism was a reform movement in the 14th-, 15th- and 16th-century Catholic Church which held that supreme authority in the Church resided with an ecumenical council, apart from, or even against, the pope.
A benefice or living is a reward received in exchange for services rendered and as a retainer for future services. The Roman Empire used the Latin term beneficium as a benefit to an individual from the Empire for services rendered. Its use was adopted by the Western Church in the Carolingian Era as a benefit bestowed by the crown or church officials. A benefice specifically from a church is called a precaria, such as a stipend, and one from a monarch or nobleman is usually called a fief. A benefice is distinct from an allod, in that an allod is property owned outright, not bestowed by a higher authority.
Church and state in medieval Europe was the relationship between the Catholic Church and the various monarchies and other states in Europe during the Middle Ages.
John of Jandun or John of Jaudun was a French philosopher, theologian, and political writer. Jandun is best known for his outspoken defense of Aristotelianism and his influence in the early Latin Averroist movement.
In the Middle Ages, the term universal power referred to the Holy Roman Emperor and the Pope. Both were struggling for the so-called dominium mundi, or world dominion, in terms of political and spiritual supremacy.
The Defensor minor is a work by Marsilius of Padua written around 1342. The Defensor minor is a restatement and defense of Marsilius's best known work, the Defensor pacis.
The history of the papacy from 1046 to 1216 was marked by conflict between popes and the Holy Roman Emperor, most prominently the Investiture Controversy, a dispute over who— pope or emperor— could appoint bishops within the Empire. Henry IV's Walk to Canossa in 1077 to meet Pope Gregory VII (1073–85), although not dispositive within the context of the larger dispute, has become legendary. Although the emperor renounced any right to lay investiture in the Concordat of Worms (1122), the issue would flare up again.
Marsilius of Padua was an Italian scholar, trained in medicine, who practiced a variety of professions. He was also an important 14th-century political figure. His political treatise Defensor pacis, an attempt to refute papal claims to a "plenitude of power" in affairs of both church and state, is seen by some scholars as the most revolutionary political treatise written in the later Middle Ages. It is one of the first examples of a trenchant critique of caesaropapism in Western Europe. Marsilius is sometimes seen as a forerunner of the Protestant reformation, because many of his beliefs were later adopted by Calvin and Luther.
The Sun and Moon allegory is used to depict a medieval political theory of hierocracy which submits the secular power to the spiritual power, stating that the Pope is like the Sun i.e. the only source of his own light, while the Emperor is like the Moon, which merely reflects lights and has no value without the Sun. It was espoused by the Roman Catholic Church of Innocent III and instantiated to some extent in medieval political practice.
In the Middle Ages, hierocracy or papalism was a current of Latin legal and political thought that argued that the pope held supreme authority over not just spiritual, but also temporal affairs. In its full, late medieval form, hierocratic theory posited that since Christ was lord of the universe and both king and priest, and the pope was his earthly vicar, the pope must also possess both spiritual and temporal authority over everybody in the world. Papalist writers at the turn of the 14th century such as Augustinus Triumphus and Giles of Rome depicted secular government as a product of human sinfulness that originated, by necessity, in tyrannical usurpation, and could be redeemed only by submission to the superior spiritual sovereignty of the pope. At the head of the Catholic Church, responsible to no other jurisdiction except God, the pope, they argued, was the monarch of a universal kingdom whose power extended to Christians and non-Christians alike.
