The Inquisition of the Middle Ages

(1) Origin

During the first three decades of the thirteenth century the Inquisition, as the institution, did not exist. But eventually Christian Europe was so endangered by heresy, and penal legislation concerning Catharism had gone so far, that the Inquisition seemed to be a political necessity. That these sects were a menace to Christian society had been long recognized by the Byzantine rulers. As early as the tenth century Empress Theodora had put to death a multitude of Paulicians, and in 1118 Emperor Alexius Comnenus treated the Bogomili with equal severity, but this did not prevent them from pouring over all Western Europe. Moreover these sects were in the highest degree aggressive, hostile to Christianity itself, to the Mass, the sacraments, the ecclesiastical hierarchy and organization; hostile also to feudal government by their attitude towards oaths, which they declared under no circumstances allowable. Nor were their views less fatal to the continuance of human society, for on the one hand they forbade marriage and the propagation of the human race. and on the other hand they made a duty of suicide through the institution of the Endura (see CATHARI). It has been said that more perished through the Endura (the Catharist suicide code) than through the Inquisition. It was, therefore, natural enough for the custodians of the existing order in Europe, especially of the Christian religion, to adopt repressive measures against such revolutionary teachings.

In France Louis VIII decreed in 1226 that persons excommunicated by the diocesan bishop, or his delegate, should receive "meet punishment" (debita animadversio). In 1249 Louis IX ordered barons to deal with heretics according to the dictates of duty (de ipsis faciant quod debebant). A decree of the Council of Toulouse (1229) makes it appear probable that in France death at the stake was already comprehended as in keeping with the aforesaid debita animadversio. To seek to trace in these measures the influence of imperial or papal ordinances is vain, since the burning of heretics had already come to be regarded as prescriptive. It is said in the "Etablissements de St. Louis et coutumes de Beauvaisis", ch. cxiii (Ordonnances des Roys de France, I, 211): "Quand le juge [ecclésiastique] laurait examiné [le suspect] se il trouvait, quil feust bougres, si le devrait faire envoier à la justice laie, et la justice laie le dolt fere ardoir. "The "Coutumes de Beauvaisis" correspond to the German "Sachsenspiegel", or "Mirror of Saxon Laws", compiled about 1235, which also embodies as a law sanctioned by custom the execution of unbelievers at the stake (sal man uf der hurt burnen). In Italy Emperor Frederick II, as early as 22 November, 1220 (Mon. Germ., II, 243), issued a rescript against heretics, conceived, however quite in the spirit of Innocent III, and Honorius III commissioned his legates to see to the enforcement in Italian cities of both the canonical decrees of 1215 and the imperial legislation of 1220. From the foregoing it cannot be doubted that up to 1224 there was no imperial law ordering, or presupposing as legal, the burning of heretics. The rescript for Lombardy of 1224 (Mon. Germ., II, 252; cf. ibid., 288) is accordingly the first law in which death by fire is contemplated (cf. Ficker, op. cit., 196). That Honorius III was in any way concerned in the drafting of this ordinance cannot be maintained; indeed the emperor was all the less in need of papal inspiration as the burning of heretics in Germany was then no longer rare; his legists, moreover, would certainly have directed the emperors attention to the ancient Roman Law that punished high treason with death, and Manichaeism in particular with the stake. The imperial rescripts of 1220 and 1224 were adopted into ecclesiastical criminal law in 1231, and were soon applied at Rome. It was then that the Inquisition of the Middle Ages came into being.

What was the immediate provocation? Contemporary sources afford no positive answer. Bishop Douais, who perhaps commands the original contemporary material better than anyone, has attempted in his latest work (LInquisition. Ses Origines. Sa Procedure, Paris, 1906) to explain its appearance by a supposed anxiety of Gregory IX to forestall the encroachments of Frederick II in the strictly ecclesiastical province of doctrine. For this purpose it would seem necessary for the pope to establish a distinct and specifically ecclesiastical court. From this point of view, though the hypothesis cannot be fully proved, much is intelligible that otherwise remains obscure. There was doubtless reason to fear such imperial encroachments in an age yet filled with the angry contentions of the Imperium and the Sacerdotium. We need only recall the trickery of the emperor and his Pretended eagerness for the purity of the Faith, his Increasingly rigorous legislation against heretics, the numerous executions of his personal rivals on the pretext of heresy, the hereditary passion of the Hohenstaufen for supreme control over Church and State, their claim of God-given authority over both, of responsibility in both domains to God and God only etc. What was more natural than that the Church should strictly reserve to herself her own sphere, while at the same time endeavouring to avoid giving offence to the emperor? A purely spiritual or papal religious tribunal would secure ecclesiastical liberty and authority for this court could be confided to men of expert knowledge and blameless reputation, and above all to independent men in whose hands the Church could safely trust the decision as to the orthodoxy or heterodoxy of a given teaching. On the other hand, to meet the emperors wishes as far as allowable, the penal code of the empire could be taken over as it stood (cf. Audray, "Regist. de Grégoire IX", n. 535).
