The triumph of intolerance was inevitable when Christianity became the religion of the State, yet the slowness of its progress shows the difficulty of overcoming the incongruity between persecution and the gospel. Hardly had orthodoxy been defined by the Council of Nicæa when Constantine brought the power of the State to bear to enforce uniformity. All heretic and schismatic priests were deprived of the privileges and immunities bestowed on the clergy and were subjected to the burdens of the State; their meeting-places were confiscated for the benefit of the Church, and their assemblies, whether public or private, were prohibited. There is an instructive illustration of theological perversity in the watchful energy with which these provisions were enforced to the suppression of heresy while yet the pagan temples and ceremonies remained undisturbed. Yet while the churchmen might feel it to be a duty thus to obstruct the development and dissemination of teachings which they regarded as destructive to religion, they still shrank from pushing intolerance to extremity and enforcing uniformity with blood, although the Emperor Julian declared that he had found no wild beasts so cruel to men as most of the Christians were to each other. Constantine, it is true, commanded the surrender of all copies of the writings of Arius under penalty of death, but it does not appear that any executions actually took place in consequence; and at last, tired of the endless strife, he ordered Athanasius to admit all Christians to the churches without distinction. No effort of the sovereign, however, could soothe the bitterness of doctrinal strife, which grew fiercer and fiercer. In 370 Valens is said to have put to death eighty orthodox ecclesiastics who had complained to him of the violence of the Arians, but this was not a judicial execution, but in pursuance of a secret order to the Prefect Modestus, who decoyed them on board of a vessel and caused it to be burned at sea.[187]

It was in 385 that the first instance was given of judicial capital punishment for heresy, and the horror which it excited shows that it was regarded everywhere as a hideous innovation. The Gnostic and Manichæan speculations of Priscillian were looked upon with the peculiar detestation which that group of heresies ever called forth; but when he was tried by the tyrant Maximus, at Trèves, with the use of torture, and was put to death with six of his disciples, while others were banished to a barbarous island beyond Britain, there was a most righteous burst of indignation. Of the two prosecuting bishops, Ithacius and Idacius, one was expelled from the episcopate and the other resigned. The saintly Martin of Tours, who had done all in his power to prevent the atrocity, refused to join in communion with them, or with any who communed with them. If he finally yielded, in order to save the lives of some men for whom he had come to Maximus to beg mercy, and also to prevent the tyrant from persecuting the Priscillianists of Spain (where, like the subsequent Cathari, they were detected by their pallor), yet, in spite of the consoling visit of an angel, he was overcome with grief at what he had done, and he found that he had lost for some time the power to expel devils and heal the sick.[188]

If the Church thus still shrank from shedding blood, it had by this time reached the point of using all other means without scruple to enforce conformity. Early in the fifth century we find Chrysostom teaching that heresy must be suppressed, heretics silenced and prevented from ensnaring others, and their conventicles broken up, but that the death-penalty is unlawful. About the same time St. Augustin entreats the Prefect of Africa not to put any Donatists to death because, if he does so, no ecclesiastic can make complaint of them, for they will prefer to suffer death themselves rather than be the cause of it to others. Yet Augustin approved of the imperial laws which banished and fined them and deprived them of their churches and of testamentary power, and he consoled them by telling them that God did not wish them to perish in antagonism to Catholic unity. To constrain any one from evil to good, he argued, was not oppression, but charity; and when the unlucky schismatics urged that no one ought to be coerced in his faith, he freely admitted it as a general principle, but added that sin and infidelity must be punished.[189]

Step by step the inevitable progress was made, and men easily found specious arguments to justify the indulgence of their passions. The fiery Jerome, when his wrath was excited by Vigilantius forbidding the adoration of relics, expressed his wonder that the bishop of the hardy heretic had not destroyed him in the flesh for the benefit of his soul, and argued that piety and zeal for God could not be cruelty; rigor, in fact, he argues in another place, is the most genuine mercy, since temporal punishment may avert eternal perdition. It was only sixty-two years after the slaughter of Priscillian and his followers had excited so much horror, that Leo. I., when the heresy seemed to be reviving, in 447, not only justified the act, but declared that if the followers of heresy so damnable were allowed to live there would be an end of human and divine law. The final step had been taken, and the Church was definitely pledged to the suppression of heresy at whatever cost. It is impossible not to attribute to ecclesiastical influence the successive edicts by which, from the time of Theodosius the Great, persistence in heresy was punished with death.[190]

A powerful impulse to this development is to be found in the responsibility which grew upon the Church from its connection with the State. When it could influence the monarch and procure from him edicts condemning heretics to exile, deportation, to the mines, and even to death, it felt that God had put into its hands powers to be exercised and not to be neglected. At the same time, with natural human inconsistency, it could argue that it was not responsible for the execution of the laws, and that its own hands were unstained with blood. Even Ithacius, in the case of Priscillian, had shrunk from the function of prosecutor and had put forward a layman in his place. Similar devices, as we shall see, were practised by the Inquisition, and in either case they were transparently false. In the vast body of imperial edicts inflicting upon heretics every variety of disability and punishment, the most ardent churchmen might find conviction that the State recognized the preservation of the purity of the faith as its first duty. Yet whenever the State or any of its officials lagged in the enforcement of these laws, the churchman was at hand to goad them on. Thus the African Church repeatedly asked the intervention of the secular power to suppress the Donatists; Leo the Great insisted with the Empress Pulcheria that the destruction of the Eutychians should be her highest care; and Pelagius I., in urging Narses to suppress heresy by force, sought to quiet the scruples of the soldier by assuring him that to prevent or to punish evil was not persecution, but love. It became the general doctrine of the Church, as expressed by St. Isidor of Seville, that princes are bound not only to be orthodox themselves, but to preserve the purity of the faith by the fullest exercise of their power against heretics. How abundantly these assiduous teachings bore their bitter fruit is shown in the deplorable history of the Church during those centuries, consisting as it does of heresy after heresy relentlessly exterminated, until the Council of Constantinople, under the Patriarch Michael Oxista, introduced the penalty of burning alive as the punishment of the Bogomili. Nor were the heretics always behindhand, when they gained opportunity, in improving the lesson which had been taught them so effectually. The persecution of the Catholics by the Arian Vandals in Africa under Genseric was quite worthy of orthodoxy; and when Hunneric succeeded his father, and his proposition to the Emperor Zeno of mutual toleration was refused, his barbarous zeal was inflamed to pitiless wrath. Under King Euric the Wisigoth, also, there was a spasmodic persecution in Aquitaine. Yet, as a rule, the Arian Goths and Burgundians set an example of toleration worthy of imitation, and their conversion to Catholicism was attended with but little cruelty on either side, except a passing ebullition in Spain at the crisis under Leuvigild, about 585, followed by disturbances which were rather political than religious. Later Catholic monarchs, however, enacted laws punishing with exile and confiscation any deviations from orthodoxy, which are notable as the only examples of the kind under the Barbarians. The Catholic Merovingians in France seem never to have troubled their Arian subjects, who were numerous in Burgundy and Aquitaine. The conversion of these latter was gradual and apparently peaceful.[191]

The Latin Church through all this had taken little part in actual persecution, for the Western mind lacked the perverse ingenuity of the East in originating and adopting heresy. With the downfall of the Western Empire it commenced the great task which absorbed its energies and by which it earned the thanks of all succeeding generations—the conversion and civilization of the Barbarians. Its new converts were not likely to indulge in abstruse speculations; they accepted the faith which was taught them, acquiesced for the most part in the established discipline, and while oft unruly and turbulent, gave little trouble on the score of orthodoxy. Under these influences the persecuting spirit died out. Claudius of Turin, whose iconoclastic zeal destroyed all the images in his diocese, escaped without punishment. Felix of Urgel was forgiven his Adoptianism, and was welcomed back into the Church in spite of his repeated tergiversations, and though not restored to his see, his residence for fifteen or twenty years at Lyons does not seem to have been an imprisonment, for he secretly maintained his doctrines, and an heretical declaration was found among his papers after his death. No force is alluded to when Archbishop Leidrad converted twenty thousand of the Catalan followers of Felix, whose principal disciple, Elipandus, Archbishop of Toledo, retained his primatial seat although there is no evidence that he ever recanted his errors. In the case of the monk Gottschalc, who disseminated his predestinarian heresy in extensive wanderings throughout Italy, Dalmatia, Austria, and Bavaria, apparently without opposition, Rabanus of Mainz finally summoned a council which condemned his doctrine in the presence of Louis le Germanique. Yet it did not venture to punish him, but sent him to his prelate, Hincmar of Reims, who, with the authority of Charles le Chauve, declared him an incorrigible heretic in the Council of Chiersy in 849. So little disposition was there to inflict penalties for heresy, though his theories struck at the root of the mediatory power of the Church, that the scourging ordered for him was carefully stated to be merely the discipline provided by the Council of Agde for the infraction of the Benedictine rule prohibiting monks from travelling without commendatory letters from their bishops; and if he was imprisoned, we are told that this was simply to prevent him from continuing to contaminate others. The Carlovingian legislation was exceedingly moderate as to heretics, merely classing them with Pagans, Jews, and infamous persons, and subjecting them to certain disabilities.[192]

The stupor of the tenth century was too profound for heresy, which presupposes a certain amount of healthy mental activity. The Church, ruling unquestioned over the slumbering consciences of men, laid aside the rusted weapons of persecution and forgot their use. When, about 1018, Bishop Burchard compiled his collection of canon law he made no reference to heretical opinions or their punishment save a couple of regulations exhumed from the forgotten Council of Elvira in 305, respecting the treatment of apostates to idolatry. Even the introduction of the doctrine of transubstantiation was received submissively until, two centuries after Gottschalc, Berenger of Tours called it in question; but he had not in him the stuff of martyrdom, and yielded to moderate pressure. The warmer faith of the Cathari, who commenced to disturb the stagnation of orthodoxy in the eleventh century, called for energetic measures, but even with those abhorred sectaries the Church was wonderfully slow to resort to extremities. It hesitated before the unaccustomed task; it shrank from contradicting its teachings of charity and was driven forward by popular fanaticism. The persecution of Orleans in 1017 was the work of King Robert the Pious; the burning at Milan soon after was done by the people against the will of the archbishop. So unfamiliar was the Church with its duty that when, about 1045, some Manichæans were discovered at Chalons, Bishop Roger applied to Bishop Wazo of Liége for advice as to what he should do with them, and whether he should hand them over to the secular arm for punishment; to which the good Wazo replied, urging that their lives should not be forfeited to the secular sword, as God, their Creator and Redeemer, showed them patience and mercy; and Canon Anselm, Wazo’s biographer, strongly condemns the executions under Henry III., at Goslar, in 1052, saying that if our Wazo had been there he would have acted as did St. Martin in the case of Priscillian. The same lenity was manifested by St. Anno of Cologne about 1060, when some of his flock refused, after repeated commands, to abandon the use of milk, eggs, and cheese during Lent, and the archbishop at length allowed them to have their own way, saying that those who were firm in the faith could not be much harmed by a difference in food. Even as late as 1144 the Church of Liége congratulated itself on having, by the mercy of God, saved the greater part of a number of confessed and convicted Cathari from the turbulent mob which strove to burn them. Those who were thus preserved were distributed among the religious houses while awaiting the response of Lucius II., to whom application was made for advice as to what should be done with them.[193]

It is not worth while to repeat in detail the cases related in a former chapter which show how uncertain was the position of the Church towards heresy at this period. There was no definite policy, no fixed rule, and heretics continued to be treated with rigor or with mercy according to the temper of the prelate concerned. Theodwin, Wazo’s successor in the see of Liége, writes in 1050 to King Henry I. of France, urging him to punish the followers of Berenger of Tours without even giving them a hearing. This uncertainty is well reflected by St. Bernard in his remarks on the occurrence at Cologne in 1145, when the zealous populace seized the Cathari and burned them despite the resistance of the ecclesiastical authorities. He argues that heretics should be won over by reason rather than by coercion, and if they will not be converted they are to be avoided; he approves the zeal of the people, but not of their action, for faith is to be spread by persuasion and not by force; yet he assumes the duty of the secular power to avenge the wrong done to God by heresy, and, blind to the danger of man’s assuming himself to be the minister of the wrath of God, he quotes St. Paul, “For he beareth not the sword in vain; for he is the minister of God, and revenger to execute wrath upon him that doeth evil” (Rom. XIII. 4). Alexander III. leaned decidedly to the side of mercy when, in 1162, he refused to pass judgment on the Cathari sent to him by the Archbishop of Reims, saying that it was better to pardon the guilty than to take the lives of the innocent. Even at the close of the century Peter Cantor dared to argue that the apostle ordered the heretic to be avoided, not slain, and he dwelt upon the inconsistency of the severity shown to the slightest deviation from faith, while the grossest sins and immoralities were allowed to go unpunished.[194]

This hesitation and uncertainty extended to the punishment appropriate to heresy. We have seen numerous cases of burning alive interspersed with sentences of imprisonment, and it was long before a definite formula was reached. Even when Alexander III., at the Council of Tours, in 1163, sought to check the alarming progress of Manichæism in Languedoc, he only commanded the secular princes to imprison the heretics and confiscate their property; though in the same year the Cathari detected in Cologne were sentenced to be burned by judges appointed for the purpose. In 1157 the punishment inflicted by the Council of Reims was branding in the face; and the same expedient was resorted to by that of Oxford in 1166. Even as late as 1199, the first measures of Innocent III. against the Albigenses only threaten exile and confiscation; there is no allusion to any duty on the part of the secular power beyond enforcing these penalties, and their enforcement is rewarded by the same indulgences as those to be gained by pilgrimage to Rome or to Compostella. As the struggle increased in bitterness, we have seen how stronger measures were adopted; yet even Simon de Montfort, in the code promulgated at Pamiers, December 1, 1212, while stimulating persecution to the utmost, and rendering it the duty of every man, does not formally adjudge the heretic to the stake, although in this very year eighty heretics were burned in Strassburg. This form of punishment had been enacted for the first time in positive law, as already stated, by Pedro II. of Aragon, in his edict of 1197, but the example was not speedily followed. Otho IV., in his constitution of 1210, simply places heretics under the imperial ban, orders their property confiscated and their houses torn down. Frederic II., in his famous statute of November 22, 1220, which made the persecution of heresy a part of the public law of Europe, only threatened confiscation and outlawry, although this, it must be added, placed their lives at the mercy of the first comer. In his constitution of March, 1224, he went farther and decreed death by fire or loss of the tongue, at the discretion of the judge; and the contemporary practice in Germany left the penalty to be similarly decided. It was not until 1231, in the Sicilian Constitutions, that Frederic rendered the punishment by cremation absolute. This was in force merely in his Neapolitan dominions, and the edict of Ravenna, in March, 1232, while inflicting the death penalty does not prescribe the method; but that of Cremona, in May, 1238, embodied the Sicilian law and thus rendered the fagot and stake the recognized punishment for heresy throughout the empire, as we find it subsequently embodied in both the Sachsenspiegel and the Schwabenspiegel, or municipal laws of northern and southern Germany. In Venice, after 1249, the ducal oath of office contained a pledge to burn all heretics. In 1255 Alonso the Wise of Castile decreed the stake for all Christians who apostatized to Islam or to Judaism. In France the legislation adopted by both Louis IX. and Raymond of Toulouse, for carrying out the provisions of the settlement of 1229, is discreetly silent with regard to the penalty of heresy, though under it the use of the stake was universal, and it is not until Louis issued his Établissements, in 1270, that we find the heretic formally condemned to be burned alive, thus rendering it part of the recognized law of the land, although the terms in which Beaumanoir alludes to it show that it had long been a settled custom. England, which was free from heresy, was even later in adopting it, and it was not until the rise of the Lollards caused fear in both Church and State that the writ “de hæretico comburendo” was created by statute in 1401.[195]

The practice of burning the heretic alive was thus not the creature of positive law, but arose generally and spontaneously, and its adoption by the legislator was only the recognition of a popular custom. We have seen numerous instances of this in a former chapter, and even as late as 1219, at Troyes, an insane enthusiast who maintained that he was the Holy Ghost was seized by the people, placed in a wicker crate surrounded by combustibles, and promptly reduced to ashes. The origin of this punishment is not easily traced, unless it is to the pagan legislation of Diocletian, who decreed this penalty for Manichæism. The torturing deaths to which the martyrs were exposed in times of persecution seem to suggest, and in some sort to justify, a similar infliction on heretics; sorcerers were sometimes burned under the imperial jurisprudence, and Gregory the Great mentions a case in which one was thus put to death by the Christian zeal of the people. As heresy was regarded as the greatest of crimes, the desire which was felt alike by laity and clergy to render its punishment as severe and as impressive as possible found in the stake its appropriate instrument. With the system of exegesis then in vogue, it was not difficult to discover an emphatic command to this effect in John, XV. 6. “If a man abide not in me, he is cast forth as a branch and is withered; and men gather them and cast them into the fire and they are burned.” The literal interpretation of Scriptural metaphor has been too frequent a source of error for us to wonder at this application of the text. An authoritative commentary on the decree of Lucius III. in 1184, ordering heretics to be delivered to the secular arm for due punishment, quotes the text of John and the imperial jurisprudence, and thence triumphantly concludes that death by fire is the penalty due to heretics, not only by divine but also by human law and by universal custom. Nor was the heretic mercifully strangled in advance; the authorities of the Inquisition assure us that he must be burned alive before the people, nay, even a whole city may be burned if heretics dwell there.[196]
