Bernard Gui (French: [ɡi]), also known as Bernardo Gui or Bernardus Guidonis (c. 1261/62 – 30 December 1331), was a Limousin Dominican friar, Bishop of Lodève, and a papal inquisitor during the later stages of the Medieval Inquisition.
Most extant detail about Gui's early life is derived from a short vita believed to have been written by his nephew, Pierre Gui, as part of a limited and ultimately unsuccessful campaign for Gui's sainthood.
Gui was born circa 1261 or 1262 in the hamlet of Royères in the Limousin region in what today is France. He entered the Dominican monastery at Limoges as a novice in the early 1270s and was received into the order by the prior of Limoges, Stephen of Salanhac, on 16 September 1280. Gui then spent the following decade studying grammar, logic, philosophy (particularly the writings of Aristotle), and theology at Dominican studia (houses of study) across southern France, including the studium generale at Montpellier.
Following the completion of his education Gui undertook a number of administrative roles at Dominican houses across southern France: he was appointed sublector of Limoges in 1291, and prior of Albi in 1294, before going on to serve in the same capacity at Carcassonne in 1297, Castres in 1301, and Limoges in 1305.
Between 1316 and 1320 Gui acted as Procurator General of the Dominican Order, representing its interests within Pope John XXII's court at Avignon, and during this time he also undertook diplomatic missions on behalf of the papacy. In January 1317, accompanied by the Franciscan Bertrand de la Tour, he was sent on a papal mission to Italy to instigate peace negotiations between the cities of northern Italy and Tuscany. Following their return to Avignon early in 1318, the two were sent to Flanders to mediate in the conflict between King Philip V of France and the Count of Flanders, Robert III. Both efforts were ultimately unsuccessful. Pierre Gui's hagiography claims that while in Avignon, Gui also performed two miracles, curing the inquisitor of Barcelona, Arnaldus Borgueti's insomnia and the friar Guillermus de Gardaga's fever and dysentery.
Gui was made Bishop of Tui on 26 August 1323, although his inquisitorial activities meant he was largely absent from the see, and Bishop of Lodève in October 1324. He died in his episcopal residence at Lauroux castle on 30 December 1331, and following his funeral in Lodève Cathedral his body was transported to Limoges to be buried in the church of the Dominican monastery. However, his tomb was looted during the late-sixteenth-century Wars of Religion.
Between 1307 and 1323, at the behest of Pope Clement V and Pope John XXII, Gui served as the chief inquisitor of Toulouse, publicly styling himself as 'Friar Bernard Gui, of the Order of Preachers, inquisitor of heretical depravity delegated to the kingdom of France by the apostolic authority'. He also assisted the inquisitors of Carcassonne, Geoffrey of Ablis and his successor Beaune, and the bishop of Pamiers, Jacques Fournier (later Pope Benedict XII). Gui's inquisitorial work took place in the Languedoc, a region that remained a "stronghold of heresy", in particular Catharism, despite the church's repeated efforts in the area throughout the thirteenth century (such as the Albigensian Crusade of 1209–1229).
In this capacity Gui travelled the region, meeting with local clergy and officials, publicly preaching about the danger of heretical teachings, and inviting those guilty of heretical sins to voluntarily confess in exchange for light penance. He then interrogated those who had been accused of heretical activity by penitents but failed to come forward voluntarily, with the secular authorities enlisted to apprehend and, if necessary, torture the accused. (A papal bull of 1252 permitted torture in cases in which there were "enough partial proofs to indicate that a full proof—a confession—was likely, and no other full proofs were available", although "a confession made after or under torture had to be freely repeated the next day without torture or it would have been considered invalid".)
The inquisitor would then hold a 'general sermon' (sermo generalis), assembling the local populace and publicly declaring the names of those judged guilty of the sin of heresy and their concomitant penances. Typical penalties included fasting, scourging, pilgrimage, the confiscation of property, or the wearing of large yellow crosses (with "the arms of the crosses [to be] two-and-a-half fingers in breadth, two-and-a-half palms in height, and two palms in width") on the front and back of outer clothing. As canon law prohibited the clergy from spilling blood, those who refused to repent or who had relapsed into heresy were handed over to the secular authorities for punishment, typically execution by burning at the stake.
During his tenure Gui held eleven such 'general sermons' in the cathedral of St Stephen in Toulouse and the cemetery of St John the Martyr in Pamiers, at which he judged 627 individuals guilty of heresy. A further nine individuals were also judged guilty at smaller events. In total, the tribunals headed by Gui convicted 636 individuals of 940 counts of heresy. In the nineteenth century the consensus among historians was that Gui had organised the burning of more than 600 individuals. However, more recent research has determined that no more than 45 of the individuals convicted by Gui (approximately 7% of the total) were executed, while 307 were imprisoned, 143 ordered to wear crosses, and nine sent on compulsory pilgrimages.
Janet Shirley states that Gui was "more interested in penitence than punishment" and generally sought to reconcile heretics to the Church. However, this interpretation has been challenged by James B. Given, who compares Gui's rates of execution unfavourably to those of secular courts in France, England, and Italy. Furthermore, based on a close reading of Gui's inquisitorial texts, Karen Sullivan has argued that he "rank[ed] among the more zealous of inquisitors" in his thought, if not actions, claiming that Gui was motivated more by a desire to safeguard the wider church community from heresy than a concern for the salvation of the individual accused heretic.
In the early fourteenth century inquisitorial activities were also characterised by increased attention to unconverted Jews, and in 1319 Gui arranged for copies of the Talmud to be publicly burnt in Toulouse, a tactic commonly used by Dominican inquisitors. Gui was also charged with investigating the lepers' plot of 1321, an alleged well poisoning conspiracy by French lepers, Jews, and Muslims; and provided an account of the event in the Flores chronicorum.
Gui was succeeded as chief inquisitor of Toulouse by Pierre Brun in July 1324.
Gui was one of the most prolific Latin authors of the Late Middle Ages, although he rarely wrote original works, preferring instead to compile and arrange existing texts, anecdotes, and records. He ordered the construction of a library at Limoges to accommodate over one hundred volumes; this was completed in 1306 and represented "one of the earliest efforts in the West to build a room devoted especially to the preservation of books".
The Dominican monastery at Limoges had been a "centre for historical study" for over a century, and Gui compiled numerous works of history (referred to by Gui as 'chronography'). These included the Flores chronicorum, a universal history from the birth of Christ to Gui's death in 1331, and various local histories, including accounts of the saints of Limousin (Traité sur les saints du Limousin), the abbey of Limoges (Traité sur l'histoire de l'abbaye de St. Augustin de Limoges), the priors of Grandmont (Chronique des prieurs de Grandmont) and L'Artige (Chronique des prieurs de l'Artige), and the bishops of Toulouse (Chronique des évêques de Toulouse) and Limoges (Catalogue des Évêques de Limoges). Additionally, he completed and significantly expanded the De Quator in quibus Deus Praedicatorum ordinem insignivit, a historical treatise on the Dominican Order begun in the 1270s by Stephen of Salanhac, and uncompleted at the time of the latter's death in 1291. This was largely completed by 1311, although Gui continued to make minor additions until his death.
