In other parts of Italy, he had grave ecclesiastical abuses to correct, and some strange bishops are immortalized in his letters. In 599, he had to issue a circular letter,[96] forbidding bishops to have women in their houses, and ordering priests, deacons, and subdeacons to separate from their wives. Sicily, controlled by his agents, gave him little trouble, but his informers reported that in Sardinia and Corsica the clergy and monks were very corrupt, and the pagans, who were numerous, bribed the officials to overlook the practice of their cult. The metropolitan at Cagliari was an intemperate and avaricious man, and Gregory, after repeated warnings, summoned him to Rome; but there is a curious mixture of indulgence and sternness in the Pope's letters, and Januarius did not go to Rome or alter his wicked ways. As to the pagans, Gregory, at first, merely urged the Archbishop to raise the rents and taxes of those who would not abandon the gods.[97] When this proved insufficient, he ordered physical persecution. If they were slaves, they were to be punished with "blows and tortures"; if they were free tenants, they were to be imprisoned. "In order," he says, in entirely mediæval language, "that they who disdain to hear the saving words of health may at least be brought to the desired sanity of mind by torture of the body."[98]

With other provinces of the old Empire, his correspondence is mainly directed to the correction of grave abuses. His letters to Spain show that Papal authority was fully recognized there, and it is of interest to find a Spanish bishop bemoaning, when Gregory urges that only literate men shall be promoted to the priesthood, that they are too few in number. Africa virtually defied his efforts to reform the Church. The province had recovered a little under Byzantine rule, but its bishops and civic officials took bribes from the Donatists.[99] They refused to persecute the schismatics, when Gregory ordered them to do so, and they defeated his attempt to break up their system of local primacies.[100] He was compelled to leave them in their perverse ways. The same condition of simony and clerical laxity prevailed generally throughout the Roman-Teutonic world, and Gregory could do little more than press for the election of good men to vacant bishoprics.

The diplomatic side of his character appears in his relations with Gaul, where the fiery and wilful Brunichildis was his chief correspondent.[101] It is true that her graver crimes were committed after Gregory's death, but he was particularly well informed, and one cannot admire his references to her "devout mind" or appreciate his belief that she was "filled with the piety of heavenly grace." When, in 599, she asked the pallium for her obsequious Bishop Syagrius of Autun, Gregory granted it: on condition that Syagrius convoked a synod for the correction of abuses and that Brunichildis attacked paganism more vigorously. When, on the other hand, the learned and devout Bishop Desiderius of Vienne, who was hated by Brunichildis for his courage in rebuking her, asked the pallium, Gregory found that there was no precedent and refused. It is true that Brunichildis was generous to the clergy and, in her way, pious; but Gregory must have known the real character of the woman whose influence he sought to win. His sacrifice, moreover, was futile. A few synods were held, but there is no trace of any diminution of simony, drunkenness, and vice among the Frankish priests and monks.

His interest in the neighbouring island of Angle-land is well known. He began, early in his Pontificate, to buy Anglo-Saxon youths and train them for missionary work, but, in 596, he found a speedier way to convert the islanders. The all-powerful Ethelbert was married to the Christian Bertha, and Gregory's friendly relations with Gaul opened the way to his court. He sent the historic mission of monks under Augustine, and, in a few years, had the converted King transforming the pagan temples into churches and driving his people into them. It was Gregory who planned the first English hierarchy.

The monks, who ought to have been Gregory's firmest allies in the reform of Christendom, had already become an ignorant and sensual body, sustaining the ideal of Benedict only in a few isolated communities, and Gregory's efforts to improve them were not wholly judicious. He insisted that they should not undertake priestly or parochial work, and he forbade the bishops to interfere with their temporal concerns. There can be little doubt that this tendency to free them from episcopal control made for greater degeneration. Here again, also, we find a curious illustration of his diplomatic liberality. As a rule he was very severe with apostate monks, yet we find him maintaining through life a friendly correspondence with a renegade monk of Syracuse. Venantius had returned to his position of wealthy noble in the world, and had married a noble dame. Gregory, it is true, urged him to return to his monastery, but the amiability of his language is only explained by the position and influence of the man. The last phase of this part of Gregory's correspondence is singular. Venantius died, and left his daughters to the guardianship of the Pope; and we find Gregory assuring these children of sin that he will discharge "the debt we owe to the goodness of your parents."[102]

We have already seen that Gregory's relations with the eastern Emperor were painful, and another episode must be related before we approach Eastern affairs more closely. The Archbishop of Salona, who was one of the typical lax prelates of the age and who had smiled at Gregory's admonitions and threats, was removed by death, and the Pope endeavoured to secure the election of the archdeacon, a rigorous priest who had been the Pope's chief informer. Neither clergy nor laity, however, desired a change in the morals of the episcopal palace, and they secured from Constantinople an imperial order for the election of their own favourite. Gregory alleged bribery and excommunicated the new archbishop. When the Emperor ordered him to desist, he flatly refused, and a compromise had to be admitted. In another town of the same frontier province, Prima Justiniana, the Emperor proposed to replace an invalid bishop with a more vigorous man, and Gregory refused to consent.[103]

A graver conflict had arisen in the East. Constantinople, with its million citizens and its superb imperial palace, naturally regarded its archbishop as too elevated to submit to Rome, and its ruling prelate, John the Faster,—a priest who rivalled Gregory in virtue and austerity,—assumed the title of "Ecumenical Bishop." Gregory protested, but the Emperor Maurice, with his customary bluntness, ordered the Pope to be silent. A few years later, however, some aggrieved Eastern priests appealed to Rome, and Gregory wrote, in entirely Papal language, to ask John for a report on their case. When John lightly, or disdainfully, answered that he knew nothing about it, the Pope lost his temper. He told his ascetic brother that it would be a much less evil to eat meat than to tell lies: that he had better get rid of that licentious young secretary of his and attend to business: that he must at once take back the aggrieved priests: and that, although he seeks no quarrel, he will not flinch if it is forced on him.[104] John made a malicious retort, by inducing the Empress Constantina to make a request for relics which Gregory was bound to refuse.

The priests were eventually tried at Rome. Whether Gregory's sentence was ever carried out in the East, we do not know, but John took the revenge of styling himself "Ecumenical Bishop" in his correspondence with Gregory, and the Pope then tried to form a league with the patriarchs of the apostolic Sees of Antioch and Alexandria against the ambitious John. In his eagerness to defeat John, he went very near to sharing the Papacy with his allies. Peter, he said, had been at Antioch before Rome, and Mark was a disciple of Peter; therefore the three were in a sense "one See."[105] He added that Rome was so far from aspiring to the odious title that, although it had actually been offered to the Popes by the Council of Chalcedon, neither Leo nor any of his successors had used it.[106]

To John himself Gregory sent a withering rebuke of his pride. To the Emperor Maurice he described John as "a wolf in sheep's clothing," a man who claimed a "blasphemous title" which "ought to be far from the hearts of all Christians"! John may "stiffen his neck against the Almighty," he says, but "he will not bend mine even with swords."[107] He assured the Empress Constantina that John's ambition was a sure sign of the coming of Anti-Christ.[108]

Gregory's peculiar diplomacy only excited the disdain of the subtler Greeks. His position is, in fact, so false—repudiating as "blasphemous" a title which, the whole world knew, he himself claimed in substance—that it has been suggested that he thought the term "Ecumenical Bishop" meant "sole bishop." Such a suggestion implies extraordinary ignorance at Rome, but there is no need to entertain it. To his friends Anastasius of Antioch and Eulogius of Alexandria, Gregory complained that the phrase was an affront, not to all bishops, but merely to the leading patriarchs, and the whole correspondence shows that there was no misunderstanding. Gregory lacked self-control. Anastasius of Antioch, though very friendly, ignored his letters; Eulogius advised him to be quiet, and hinted that people might suggest envy; the Emperor treated him with silent disdain. John died, but his successor Cyriacus actually used the offensive title in telling Gregory of his appointment. There was another outburst, and Maurice impatiently begged the Pope not to make so much fuss about "an idle name." Eulogius of Alexandria, who had some sense of humour, addressed Gregory as "Universal Pope," saying gravely that he would obey his "commands" and not again call any man "Universal Bishop." Possibly Eulogius knew that Gregory had, a few years before, written to John of Syracuse: "As to the Church of Constantinople, who doubts that it is subject to the Apostolic See?"[109] Gregory protested in vain until the close of his life. The Greeks retained their "blasphemous" title: the Latins continued to assert their authority even over the Greek bishops.
