2. Enrico del Carretto came from an important Genoese family, related and allied to the Fieschi. Bachelor in theology at Paris, he then became lector at the Franciscan studium in Bologna. Pope Boniface VIII appointed him bishop of Lucca in 1300 against the canons' choice. On account of political troubles in Lucca, he left the city for Avignon at the beginning of John XXII's pontificate. In 1308, Enrico had been in charge of composing the synodal statutes of his city. Interesting for our purposes is the fact that one of its chapters concerns the prohibition of incantations and divination, which strongly suggests that Enrico was convinced of the effective power of such practices. He died in 1324. See Boureau, , Le pape et les sorciers, xii–xiii.Google Scholar

4. The doctrinal tradition that views the sacrament as a contractual relation with God can be traced back to Augustine, especially his theory of relation as a noninherent accident, combined with his idea that the signification of signs depends on a freely willed convention between men, independently of the natural properties of the sign. Notable proponents of this view were William of Auvergne, bishop of Paris between 1228 and 1249, the Oxford theologian Richard Fishacre, Robert Grosseteste, and later followers include the Dominican Robert Kilwardby, Bonaventure, and Peter John Olivi.

9. Guido Terreni was of Catalan origin and had been the pupil of Godfrey of Fontaines at Paris. He was regent master there around 1312–16, when he taught John Baconthorpe and Sigebert of Bekke. He was regent at the Carmelite studium in Avignon, lector at the sacred palace in 1317–18, provincial prior of Provence (before its division between the provinces of Provence, Narbonne, and Catalonia), and general prior of the order in 1318–21. Shortly after the 1320 commission on witchcraft he was appointed bishop and inquisitor of Majorca (1321–32), and then of Elne from 1322 until his death in 1342.

12. As Alexander Murray has kindly made me aware, the practice of consulting canon lawyers grew considerably in the fourteenth century. Baldus de' Ubaldi (d. 1400) left over 2500 consilia, much studied by later lawyers. Clement V had consulted Oldradus de Ponte regarding the war of Robert of Naples and Henry VII. John's practice seems to echo this. See Riesenberg, P., “The Consilia Literature: A Prospectus,” Manuscripta 6 (1962): 3–22CrossRefGoogle Scholar; Baumgartner, I., ed., Consilia itn späten Mittelalter: Zum historischer Aussagewert einer Quellengattung (Sigmaringen: Thorbecke, 1995)Google Scholar. I am very grateful to Mr. Murray for his attentive reading and valuable comments on this paper. We later find the same Oldradus involved in the defense of one John of Partimach, accused of heresy by two Dominican inquisitors on account of his practicing sortilege. Oldradus's defense has come to us in the form of a small treatise on the question whether sortilege can be qualified as heresy. This treatise, which enjoyed great authority in later literature, explores the legal side of the relation between man and the devil, and the inquisition's judgment of practices associated with it. Oldradus bases his argument on the traditional definition of heresy as an intellectual error and concludes that simple sortilege, as the one involved in this case, is not tantamount to heresy but is only superstitious. Association with the devil is not considered heretical unless it involves reverence.

13. In the order in which they appear in the text, the members of the papal commission were: the Dominican Augustin Kazotic, bishop of Zagreb since 1303; John Wülfing von Güttingen, bishop of Brixen since 1306; the Franciscan Enrico del Carretto, bishop of Lucca; the Dominican James of Concotz, papal confessor and bishop of Lodève since 1318; Guido Terreni, general of the Carmelites; Alexander Fassitelli of St. Elpidio, general of the Augustinians since 1312; the Franciscan Arnaud Royard, master of theology in Paris; the Augustinian John of Rome, master of theology in Paris since 1319; the Augustinian Gregory of Lucca, master of theology in Paris until 1322, then bishop of Sorra in Sardinia; and finally, the Cistercian Jacques Fournier, bishop of Pamiers since 1317 and future pope Benedict XII.

14. The practice of consulting a body of experts was a feature of John XXII's pontificate and was to be repeatedly employed by him, notably on the question of apostolic poverty during the conflict with the Franciscans (1322–24), and later during the beatific vision controversy (1330s), although in this case the consultation was a result, rather than the occasion, of John's doctrinal blunder. Another case in which John consulted experts took place in early 1318, when he inquired whether a series of statements made by some Franciscan Spirituals about the relation between Church authority and the Franciscan vows were tantamount to heresy. The doctrine involved was derived from Peter John Olivi's teaching. Among the members of the commission were the Carmelite Guido Terreni and the Dominican Durandus of St. Pourçain.

18. It is not surprising that Guillaume should have been assigned as spokesman of the pope in front of the inquisitors. Guillaume was born in Bayonne in 1260 and joined the Dominican house of Béziers fairly early, in 1279, before studying in several convents of the southwest and undertaking studies in theology at Montpellier. His university career began proper in 1306, after a period of teaching in Toulouse, when Clement V appointed Guillaume lector at the sacred palace. Clement then made him cardinal in 1312, at the same promotion that included Jacques Duèze, future John XXII. Guillaume enjoyed a good reputation and a rather broad experience, for he was at once a well-known theologian (his commentary on the Sentences, written towards 1300, was known as the “Lectura Thomasiana”), an active member of the Dominican order (general preacher of Narbonne in 1289, definitor of Cahors in 1298, provincial prior of Provence in 1301), and a curialist (appointed in 1309 by Clement V to look after the posthumous process against Boniface VIII). John XXII appreciated his merits, for he promoted Guillaume as cardinal-bishop of Sabina in 1317, and later appointed him as pontifical legate in Spain from 1320 to 1324. Guillaume's departure for Spain probably explains why he was absent at the consultation on witchcraft. Otherwise, it is unlikely that the pope would have overlooked his participation.

A previous case, known from a letter that the pope addressed in July 1319 to Jacques Fournier, bishop of Pamiers and future member of the 1320 commission, assimilates invocations of the devil to heresy. The pope commands the bishop to persecute the three persons involved—a cleric, a Carmelite, and a woman, whom he accused of fabricating wax images and consulting with the demons with harmful purposes (maleficium).

21. The canon Episcopi has been edited by Hansen, J.: Quellen, 38–39Google Scholar. The canon, dealing with “De mulieribus, quae cum daemonibus se dicunt nocturnis horis equitare,” probably originated in some Carolingian synodal statute. For an illustrative passage: “quaedam sceleratae mulieres retro post Satanam conversae daemonum illusionibus et phantasmatibus seductae, credunt se et profitentur nocturnis horis cum Diana paganorum dea…. Nam innumera multitudo hac falsa opinione decepta haec vera esse credit, et credendo a recta fide deviat et in errorem paganorum revolvitur, cum aliquid divinitatis aut numinis extra unum deum esse arbitratur. Quapropter sacerdotes per ecclesias sibi commissas populo omni instantia praedicare debent, ut noverint, haec omnimodis falsa esse, et non a divino sed a maligno spiritu talia phantasmata mentibus infidelium irrogari” (my emphasis).

The distinction between the absolute and ordained power of God rested on the fundamental perception that what God created or established did not exhaust divine capacity or the potentialities open to God. The twin formula de potentia absoluta and de potentia ordinata was introduced in the early thirteenth century and became commonplace scholastic terminology by midcentury. In its classic shape, the formula signified two ways of speaking about divine power. One way of speaking is to discuss power in the abstract, without regard for God's will and actions as revealed in the present order. The other way is to view divine power in terms of what God has in fact chosen to do. Thus, certain things that are theoretically possible to God de potentia absoluta are impossible to God in light of the chosen order, de potentia ordinata. For a thorough study of this distinction, see Courtenay, W.

29. Aquinas's theory of sacramental causality undergoes some changes between his early commentary on the Sentences and the later Summa. In his commentary he maintained that the sacrament is an “instrumental dispositive” cause of grace, in that it “disposes” the soul to receive grace by impressing the character in it. See Sent. 4.1.1.4. In the Summa he abandons the notion of dispositive cause in order to consider the sacrament simply as an instrumental cause of grace. God is the ultimate cause of both grace and the character, but by means of the action of the sacrament. See ST 3.62.1; also 3.62.4 and 6. See Rosier-Catach, , Parole éfficace, 135–39.Google Scholar

30. See Aquinas, , Sent 4Google Scholar.1.1.4; ST 3.62.1. On the same grounds, Aquinas will dismiss the example of the leaden coin as a valid illustration of sacramental causality: In Ethic. 5.9.978–91; in Polit. 1.7.111–21; ST 2a2ae.78.

34. In this respect, Alain Boureau has suggested that Enrico could have probably derived his explanation of the mode of presence of the devil from Olivi's commentary on the Apocalypse. Examining the possibility of making an image of the Antichrist talk (13, 15), Olivi reports on two interpretations, that of Joachim de Fiore and that of Richard of St. Victor. He rejects Joachim's and espouses Richard's opinion that the diabolic spirit “assists” the imitators of the Antichrist. Olivi adds to Richard's interpretation the verb assistere (to be present, to assist, to help), which for the advocates of contractual causality denotes precisely the mode of God's presence in the sacrament. Boureau speculates that Enrico could have become familiar with Olivi's terminology in the curia, where a number of theologians were working since 1318 on the censure against Olivi's commentary. Among the theologians commissioned with this work were Guido Terreni, also a member of the 1320 commission, and Pierre de la Palud.

Sacerdos enim ipsam consecrat cum invocatione trinitatis in aqua consacrata; que omnia divina sunt ordinata ad honorem instituentis rationem signi in ymagine….

Unde si esset aliqua ymago facta per artem humanam solum, non consacrata, sed solum esset ymago pura ex narura materie seu et modo sue factionis, et pungeretur sicut ymago sacrata ab aliquo, qui non crederet aliquam virtutem in ymaginis esse respectu maleficii quod intendit, sed credit dyabolum hoc posse vere et ad hoc pungit ymaginem, ut dyabolus pungat maleficiatum, sine omni pacto et fide et reverencia, tune esset supersticiosum solum et non hereticum.

For similar cases, see also Duvernoy, J., ed., Le registre de l'Inquisition de Jacques Fournier, 3 vols. (Paris: Mouton, 1978)CrossRefGoogle Scholar. Jacques Fournier was another member of the 1320 commission, and it is interesting to see the number of cases dealing with witchcraft and black magic that are recorded in his register around the same year. See 280–84, 309, 322, 350, 597, 675 (magic and superstition); 283 (witchcraft); 448, 987,1251 (sortilege).

44. I borrow Alain Boureau's term: Satan hérétique, 45–46.

45. “[Heresis] sit falsa et erronea opinio in intellectu, ut videlicet falso opinetur et contra veritatem senciat de aliquo. Et ratio huius est quia heresis est quedam species infidelitatis et ideo opponitur fidei. Fides autem est verus assensus in intellectu. Ergo, heresis erit assensus falsus contra veritatem fidei”: Boureau, , Le pape et les sorciers, 43Google Scholar (f. 18v). The entirety of Guido's opinion covers 43–85 (BAV Borghese 348, ff. 18v–37r).

46. The term “presumption of law” (praesumptio juris) generally signifies a reasonable conjecture concerning something doubtful, drawn from arguments and appearances, which by the force of circumstances can be accepted as a proof. Presumption has its place in canon law only when positive proofs are wanting, and yet the formulation of some judgment is necessary. It is never in itself an absolute proof, as it only presumes that something is true. See Taunton, E. L., The Law of the Church (New York: n.p., 1906)Google Scholar, s. v. “Presumption”; Ferraris, L., Bibliotheca canonica, juridica, moralis, theologica, ed. Migne, J.-P (Paris: Petit-Montrouge, 1861–1865)Google Scholar, s. v. “Praesumptio.”

47. “Cum judicium de re accipitur quoad ilia et respectu illorum que per se et ex natura sui conveniunt et non respectu eorum que per accidens, ex actu exteriori sumetur judicium de interiori quem significat ut causam per se et ex natura sui ipsum respicit, non interiori intentione operands. Quod probo: nam si ex actu exteriori deberet sumi judicum de interiori secundum intentionem operantis, nunquam de actu interiori posset haberi judicium humanum…. Dico igitur quod judicium humanum accipitur ex actu exteriori de interiori quem rescipit actus exterior ex sui natura tamquam causam et non de illo quem respicit ut causam non per se nec ex natura sui, sed per accidens ex relatione et intentione operantis”: Boureau, , Le pape et les sorciers, 62–63Google Scholar (f. 26v–27r).

48. “Quod aliquis ex actu hereticali judicetur hereticus, non intelligitur quod actus exterior dicatur hereticale sic quod heresis formaliter sit in actu exteriori. Hoc enim est impossibile cum formaliter heresis sit in intellectu, sed pro tanto dicitur actus exterior hereticalis quia significat in operante heresim, sicut effectus significat causam et signum suum significatum; et similiter verbum exterius dicitur hereticale non quod heresis sit formaliter in voce, sed quia significat in loquente heresim et quod habeat sic dicens errorem contra fidem in intellectu”: Boureau, , Le pape et les sorciers, 64Google Scholar (f. 27r–v).

49. In an interesting allusion to Lateran IV's decree Excommunicamus against rulers who aided heretics, Guido admits the possibility that the ruler could be prompted in his action not by a desire to encourage the heretic in his error, but by a compassionate intention. But whatever the case, Guido says that what is evident (constat) to the Church is the heretical act of perpetrating heresy. As such, the ruler should be judged heretical and excommunicated according to the Lateran decree: see Boureau, , Le pape et les sorciers, 70Google Scholar (f. 30r).

50. “Constat quod intentio qua operans operatur, puta qua intentione dat elemosinam non potest ab nomine sciri quia nemo novit que sunt hominis nisi spiritus hominis qui est in eo, ut Apostolus dicit [I Cor. 2, 11]…. Unde dans elemosinam inopi judicabitur compatiens et nisi ex actu intentionis qua dat nee etiam intentio illa per actum exteriorem pateret”: Boureau, , Le pape et les sorciers, 63Google Scholar (f. 26v–27r). Also 73–74 (f. 31v–32r): “Unde dicendum quod factum hereticale ex natura sui arguit per se causam heresim, quamvis per accidens ex intentione agentis possit ab alia causa fieri sicut ex natura sua dare indigenti arguit in dante compassionem tanquam per se causam, potest tamen ex intentione facientis in relatione ad aliam causam, puta inanem gloria fieri et quia judicium debet sumi ex hiis que per se, nisi aliud appareat, et non ex hiis que per accidens ut, nisi aliud appareat ex actu exteriori dandi elemosinam indigenti debet tanquam ex per se effecru judicari dans elemosinam habere compasionem et non id quod secundum intentionem dantis potest intendi.”

53. “Et confirmatur quia certum est quod de verbo exteriori confitens et negans trinitatem personarum in divinis judicatur hereticus quia judicium sumitur quod male sentiat de fide trinitatis ex verbo quod ex narura sui est expressivum talis erroris et proprium signum ejus…. Et similiter adorans hereticum judicatur hereticus quia talis adoratio signum est quod placeat sibi heretica doctrina quam in heretico veneratur et tamen certum est quod sic adorans potest alia intendere ut quod hoc faciat timore aut favore alicuius tyranni heretici magni. Ergo, judicium ecclesie erit ex actu exteriori de acti interiori quem de se respicit et ex sui natura tanquam per se causam, et non judicabitur per actum istum exteriorem de actu intentionis operantis…. Judicum autem ex signo fallibili non est omnino infallibile. Igitur judicium de actu interiori per actum exteriorem, puta ex facto hereticali accipitur iudicium quod aliquis est hereticus, tale judicium non est omnino infallibile”: Boureau, , Le pape et les sorders, 63–64 (f. 27r–v).Google Scholar

54. “Igitur, cum non dicatur factum hereticale nisi quia est effectus heresis et signum quo in faciente probatur heresis, dicere quod aliquis operetur factum hereticale et per hoc non judiceretur hereticus est se interimere… tunc cum actus exterior denominetur ab actu interiori sicut a sua causa, si non patet quod sit ab heresi, non debet dici actus hereticalis…. Item si sic, scilicet quia tale factum potest fieri absque heresi et absque hoc quod male sentiat baptizans de baprismo et potest in urramque causa reduci, non potest judicari ex hoc hereticus… et sic non poterit aliquis de heresi puniri, quod est inconveniens valde”: Boureau, , Le pape et les sorders, 73Google Scholar (f. 31v).

58. “Secundum judicium ecclesie judicabitur aliquis hereticus ex verbo vel facto hereticali quod verbum vel factum arguit heresim in intellectu quantum est in se, nisi ibi sit mendacium verbi vel facti aut aliter excusetur per evidenciam. Unde oportet quod dicens vel faciens contra fidem probet facto evidenter quod mentiebatur aut quod ex ignorantia hoc fecit; aliter, nisi constet de opposito ecclesia judicabit eum hereticum. Et est simile: aliquis est manifestus peccator; moritur absque confessione et sacramento penitentie in puncto mortis, amissa loquela et omni expressione qua possit exterius confiteri aut ostendere se dolere de peccato; nichilominus interius conteritur; iste per ecclesiam judicabitur damnatus et secundum Deum erit salvus” (my emphasis): Boureau, , Le pape et les sorciers, 65Google Scholar (f. 27v–28r).

59. This is not to deny that Guido might have later developed his view along hard infallibility lines, especially in the context of later 1320s disputes over irreformability initiated by the Franciscans.

64. “Honor dulie non debetur dyabolo, immo contemptus et irreverencia ratione obstinate malicie et culpe, et oppositum credens est hereticus, sicut credens dyabolum esse in gratia aut in via ad gratiam. Unde cum dyabolus sit omnino adversus a Deo absque spe conversionis et dulie honor non debeat exhiberi nisi habentibus communicationem ad Deum per gratiam aliquo modo sive quia formaliter habeant gratiam aut possunt habere vel agunt ad gratiam vel subministrant. Ideo, credens quod dyabolo vel eis qui subserviunt sue maleficie operationi debeatur honor dulie, est hereticus quia hoc est credere quod dyabolo et sue male operationi debeatur honor. Ergo, credens quod ex virrute dyaboli verba Christi habeant efficaciam ad maleficium est male sentire de verbis Christi quod eis debeatur honor et non debeatur, quod est hereticum”: Boureau, , Le pape et les sorciers, 72–73Google Scholar (f. 31r). Curiously, in his famous Summa de haeresibus, composed around 1340 after he had been inquisitor of Majorca, Guido does not mention idolaters of the devil or authors of black magic within his catalog of heretics. Could this be understood as an implicit, posthumous criticism of the pope's doctrinal program of extending the meaning of heresy to include these practices?

65. Thus Guido, : “Debitum autem non est respectu impossibilium cum ad impossibile nulla sit obligatio. Ergo non potuerunt verba Christi sacramentalia esse misteria dyaboli, et oppositum senriens irreverenter sentit et male de verbis sacramentalibus Christi”: Boureau, Le pape et les sorciers, 73 (f. 31v).Google Scholar

66. “Invocatio cum adoratione qua invocatur demon est protestatio false fidei; hoc enim patet de invocatione cum adoratione latrie quia sic invocans ut sacrificans vel alio exteriori cultu latrie exhibens honorem divinum demoni protstatur se credere demonem esse a quo credit regi et salvari; protestatur etiam se credere in demonem tanquam Deum et ideo ex hoc actu exterioris latrie judicabitur se credere alium Deum quam verum et a demone consequi regimen et salutem, quod est contra fidem”: Boureau, Le pape et les sorciers, 83 (f. 36r). Also ibid: “Nihil enim adoratione dulie adoratur nisi propter ordinem quern habet ad Deum a quo ordine recessit et omnino aversus dyabolus propter maliciam obstinatam…. Ergo sic adorans hereticum judicatur hereticus, multo magis invocando adorans demonem debet judicari hereticus”: 84 (f. 36v): “unde et sic invocantes demonem ad effectus proprios Dei judicandi sunt heretici, quasi credant demonem posse sicut Deus… Si invocans crederet quod demon ilia que subsunt sue virtuti naturali demonis posset facere non permissus a Deo, talis invocans esset hereticus, male sentiens de Dei potentia contra scripturam.”

67. “Baptizare ymagines ad maleficium, etsi patenter sit sortilegium, nihilominus habet judicari per ecclesiam committere heresim. Unde non reducitur ad sortilegia quecumque sed ad sortilegia que manifeste sapiunt heresim, ut expresse notatur Extra, de hereticis, Libro Sexto, cap. Accusatus et Sane [Sexto, 5.2.8, CIC 2: col. 1071–1072]”: Boureau, Le pape et les sorciers, 74 (f. 32r).

68. In November 1330, John XXII sent two letters, one addressed to the archbishop of Narbonne and the inquisitor of Carcassonne, the other to the archbishop of Toulouse and his inquisitor, containing a copy of a letter sent in 1320 by Guillaume de Peyre Godin to the inquisitors of Carcassonne and Toulouse, ordering its recipients to devote themselves with particular zeal to the persecution of cases of satanic invocations. The new letter included however an important corrective, whereby the inquisitors must seek to complete their task and assist the bishops, but abstain from opening new procedures without previous pontifical commission. For an edition of this letter, see Hansen, J., Quellen, 6–7Google Scholar. For John XXII's legal innovations and distrust of the inquisition, see Boureau, , Satan hérétique, 41–60.Google Scholar

69. A prime example of this is the trial of the Templars, in which the inquisition became subordinate to the royal power. See Cohn, , Europe's Inner Demons, 90–94Google Scholar. For other vivid examples, see also Murray, A., “The Inquisition and the Renaissance,” Raleigh Lecture on History, Proceedings of the British Academy 131 (2005): 91–126, esp. 109–10, 112–14, 124–25Google Scholar; and “Beware of the Universities: A Cautionary Tale from Paris, 1380–1381,” in Medieval Paradigms: Essays in Honor of Jeremy Duquesnay Adams, ed.

Vrin, 1960)Google Scholar. Indeed, after ca. 1300, the inquisition underwent new developments. It had the most streamlined, up-to-date procedure of any court, and one supremely open to use by authority. Hence the tendency to enlarge the concept of “heresy.” That the notion of heresy extended under John XXII to black magic is just one instance of this general expansion, occasioned by the configuration of pressures created by the new court. I thank Alexander Murray for his enlightening comments on this issue.

72. The Church's attitude towards these practices was ambivalent until well into the 1270s, since, as we know, popes in search of the elixir of life tended to protect the study of alchemy. See Bagliani, A. Paravicini, II corpo del papa (Turin: Einaudi, 1994)Google Scholar. After the condemnations, however, this science began to be regarded with more suspicion. Indeed, bishop Tempier's syllabus of 1277 was preceded by a prologue that condemned those “books which either dealt with black magic or registered cases of witchcraft, invocations of the devil, or other practices which could put the soul in danger.” In response, we see Cardinal Francesco Orsini ordering, in his will of 1304, the burning of all his books of alchemy.

74. For an edition of John's bull, see Hansen, J., Quellen, 5–6Google Scholar. John's bull does not appear in the two canonical collections that completed the Corpus iuris canonici and that included John's Extravagantes. The first collection of John XXII's bulls was composed in 1325 by Jesselin de Cassagnes, who did not have the time to complete it before his death. A second collection had to wait until the beginning of the sixteenth century, at a time when John's doctrine on witchcraft had become banal. The only mentions of the bull are found in the manual of Nicholas Eymerich in 1376, in Rinaldi's Annales ecclésiastiques, and in a Roman eighteenth-century collection of bulls. It is in fact remarkable that there should be no traces of John's bull in the papal registers: see Boureau, , Satan hérétique, 20–25.Google Scholar

76. Thus, an anonymous commentary of about 1330 on John XXII's constitution draws precisely on the idea of “pact” in order to prove the “heretical fact” in black magic: “Adorare daemonem, baptizare imagines et talia sunt valde gravia peccata et modernis temporibus multum incipiunt pullulare. Valde rartionabiliter posset ecclesia statuere, quod talia facientes, etsi non haberent errorem fidei in intellectu, si facerent hoc praecise propter aliquid pactum demone habitum, velut heretici punirentur, et forsitan expediret, ut propter gravitatem pene homines a talibus arcerentur. Utrum autem hoc sit iam statutum per aliqua iura, plenius noverint iuriste”: Vat. Lat. MS 4869, f. 79. See Hansen, J., Zauberwahn, 267–68Google Scholar. Likewise, Zanchinus Ugolini's treatise De hereticis, composed around 1330, mentions the central importance of a “pact” with the devil in the definition of heresy. The author belonged to the circle of inquisitors of the Romagna of around 1302–40. The treatise, highly influential in the sixteenth and seventeenth centuries, was written as a manual for the inquisitor Donatus St. Agatha O.F.M. See Hansen, J., Zauberwahn, 268–70.Google Scholar
