Damasus at once used his powers. He convoked a synod at Rome, and we may realize the enormous progress that the Church had made in fifty years when we learn that ninety-three Italian bishops responded to his summons. On a charge of favouring Arianism, which seems to cloak a real charge of favouring Ursicinus, the bishops of Parma and Puteoli were deposed by the synod, and they appealed in vain to the court. Henceforward bishops—under the presidency of the Bishop of Rome—were to judge bishops. The cultivated and courtly Auxentius of Milan was next condemned, but he was too secure in the favour of the Empress to do more than smile. Neither he nor his great successor, St. Ambrose, acknowledged any authority over them on the part of the Roman bishop.

From this synod, moreover, the bishops wrote to the Emperor to ask that secular officials should be instructed to enforce their jurisdiction and sentences, and we shall hardly be unjust if we suspect the direct or indirect suggestion of Damasus in their further requests. They asked that bishops might be tried either by the Bishop of Rome or by a council of fifteen bishops, and that the Bishop of Rome himself might, "if his case were not laid before an (episcopal) council," defend himself before the Imperial Council.[36] This bold attempt of the Roman bishop to judge all bishops, yet be judged by none, seems to have displeased the Emperor, who may have consulted the Bishop of Milan. We have, at least, no indication that the privilege was granted. But the other points were granted, and instructions were issued to the secular officers, in Gaul as well as in Italy, apprising them of the juridical autonomy of the Church and of their duty to enforce its decisions. Out of his troubles Damasus had won a most important step in the making of the Papacy.

Unfriendly critics might suggest that Damasus paid a price for these powers. A curious passage in the historian Socrates[37] tells us that, in the year 370, Valentinian decreed that every man might henceforward marry two wives. The statement is often rejected as preposterous, but we know that Valentinian had, shortly before, divorced his wife, Severa, in favour of the more comely Justina, and it is probable enough that he passed a law of divorce. The learned Tillemont blushes when he finds no ecclesiastical protest at the time against this flagrant return to pagan morals.

However that may be, Damasus, from his palace by the Lateran Basilica, continued to strengthen his new authority and to regulate the disordered Church. Rome still harboured numbers of rebels, and they seem to have caused him serious annoyance by a persistent charge that, in earlier years, he had sinned with a Roman matron. A converted and relapsed Jew was put forward as the chief witness to the charge, and, when the young Emperor Gratian had failed to impress Rome by his personal assurance that Damasus was innocent, a Roman synod of forty-four bishops professed to investigate and dismiss the accusation. Ursicinus was now, however, living at Milan, and it is not implausibly suggested that his insistence made some impression on the puritanical young Emperor. The case was submitted to the Council of Aquileia in 380, at which St. Ambrose presided, and the bishops declared the innocence of Damasus and demanded the secular punishment of his accusers, who were now scattered over Europe. The Roman rebels then masked their hostility by joining an eccentric, though orthodox, sect in the capital whose ascetic leader bore the name of Lucifer. On these Luciferians in turn the hand of Damasus fell with ruthless severity. Their renowned Macarius, the champion faster of the time outside the Egyptian desert, was physically dragged into court and banished, and the "police" pursued them from one secret meeting-place to another. It is at this time that Faustinus and Marcellinus, who had joined the rigorous sect, addressed their Libellus to the Emperors.

Over the remainder of Italy and over Gaul Damasus did not press the virtual primacy which he had won from the imperial authorities, and the later language of Leo and Gregory makes it advisable for us to grasp clearly the situation in the fourth century. There was no question of Papal supremacy. No important decision was reached by Damasus apart from a synod, and the See of Milan was not regarded as subordinate in authority to that of Rome; though St. Ambrose naturally expressed a peculiar respect for the doctrinal tradition of a church that had been founded by the great apostles. When the Spanish Priscillianists applied to Italy for aid, they appealed, says Sulpicius Severus, "to the two bishops who had the highest authority at that time." When the great struggle with the pagan senators over the statue of Victory took place in 382, it was Ambrose who championed Christianity, Damasus merely sending to him the Roman petition. But Damasus knew the theoretical strength of his position, and knew, as a rule, when to enforce it. In 378, the Emperors severed Illyricum (Greece, Epirus, Thessaly, and Macedonia) from the Western Empire. Damasus at once contrived that its bishops should look not to the Eastern churches but to himself for direction and support, and from that time onward the Bishop of Thessalonica became the "Vicar" of the Bishop of Rome.

We must leave this vague and imperfect primacy in the West, with its secular foundations, and turn to the more interesting and adventurous course of the diplomacy of Damasus in the East. The narrow limits within which each of these sketches must be confined forbid me to attempt to depict the extraordinary confusion of the Eastern Church. It must suffice to say, in few words, that the struggle against paganism was almost lost in the fiery struggle against heresy, and that the hand of the Arian Valens smote the orthodox as violently and persistently as the hand of any pagan emperor had done. The various refinements of the Arian heresy, the lingering traces of old heresies, and the vigorous beginnings of new heresies, rent each church into factions as violent as those of Rome, and made each important See the theatre of a truculent rivalry. Constantinople, or New Rome as it loved to call itself, was the natural centre of the Eastern religious world, but it was overshadowed by the Arian court and its growing pretensions were watched by the apostolic churches of Antioch and Alexandria almost as jealously as by Old Rome. The triumph over paganism had, before it was half completed, given place to a dark and sanguinary confusion, from the shores of the Euxine to the sands of the Thebaid.

In 371 St. Basil appealed to Damasus for assistance. He sent the deacon Dorotheus with a letter[38] asking the Italians to send to the East visitors who might report to them the condition of the churches. Damasus, not flattered by the lowliness of the embassy or by the smallness of the request, and still much occupied in the West, merely sent his deacon Sabinus. To a further impassioned appeal from Basil he gave no clearer promise of aid, and Basil indignantly observed that it was useless to appeal to "a proud and haughty man who sits on a lofty throne and cannot hear those who tell him the truth on the ground below."[39] Basil made further futile appeals to the West, though not to Damasus, and at length, in 381, the Eastern bishops met in the Council of Constantinople, discussed their own affairs, and, in a famous canon, awarded the See of Constantinople a primacy in the East. Shortly afterwards a synod was held in Italy, under Ambrose, and it sent to the Emperor Theodosius a letter in which the concern of the Italians was plainly expressed.[40] The bishops ask Theodosius to assist in convoking an Ecumenical Council at Rome, and say that "it seems not unworthy that they [the Eastern bishops] should submit to the Bishop of Rome and the other Italian bishops"; though they "do not claim any prerogative of judgment." It is interesting to note at this stage how the Bishop of Rome does not yet stand apart from the other Italian bishops or claim jurisdiction over the East. In a letter written by Damasus somewhere about this time to certain oriental bishops, there is question of "reverence for the Apostolic See" and of the foundation of that See by Peter, but such language is rare and premature, and is not implausibly ascribed to St. Jerome, who was then at Rome.[41] To the Eastern emperor and to the Eastern patriarchs it is not addressed.

Theodosius ignored the request, and sanctioned the holding of another Council at Constantinople. The Westerns had, in the meantime, announced an Ecumenical Council at Rome for the summer of 382, and invited their Eastern brethren. From one cause or other, the proceedings at Rome were delayed, and, while the Italians still anxiously awaited the response to their invitation, a letter came with the message that the Eastern bishops had settled the questions in dispute, and they regretted that they had not "the wings of a dove" in order that they might fly from "the great city of Constantinople" to "the great city of Rome." The letter is a model of polite and exquisite irony.[42] The statesmanship of Damasus had hopelessly miscarried, and the Eastern and Western branches of Christendom were farther than ever from uniting under his presidency.

A more intimate aspect of the character of Damasus is disclosed when we consider the condition of the Roman clergy during his Pontificate. It almost suffices to recall that an imperial rescript of the year 370 forbade priests and monks to visit the houses of widows and orphans, and declared that legacies to them were invalid. St. Jerome himself deplores that there were solid reasons for thus depriving the clergy of a privilege which every gladiator enjoyed, and that the law was shamefully frustrated by donations.[43] Indeed, in 372, the law was extended to nuns and bishops, and for nearly a hundred years the Roman clergy bore the stigma which was implied by such a prohibition.

Jerome's letters ruthlessly depict the condition of the Roman community. Fresh from his austerities in the desert of Chalcidia, the impulsive monk was as ready to denounce vice as to encourage virtue, and evidences of singular laxity mingle with heroic virtue in his vivid pages. On the one hand he directed, in the sobered palace of Marcella on the Aventine, a group of noble dames in the practice of the most rigorous piety and the cultivation of sacred letters. The populace even threatened to fling him into the river, when the lovely and high-born Blesilla terminated her austerities by a premature death, and even Christian writers fiercely contested this introduction into Rome of the ideals of the Egyptian desert. But, on the other hand, Jerome's directions to his pupils incidentally betray that, beyond his little school of virtue and learning, he saw nothing but sin and worldliness. In plain and crude speech he warns his pupils to shun their Christian neighbours and distrust the priests. Sombre as are many of the letters which Seneca wrote in the days of Nero, not one of them can compare with Jerome's lengthy letter to the gentle maiden Eustochium.[44] He fills her virgin mind with a comprehensive picture of frailty and frivolity, and tells her that she may regard, not as a Christian, but as a Manichæan, any austere-looking woman whom she may meet on the streets of Rome. He denounces "the new genus of concubines," the "spiritual brothers and sisters," who share the same house, even the same bed, and, if you protest, complain that you are evil-minded. Eustochium is to avoid gatherings of Christian women, and must never be alone with these clerics, who, exquisitely dressed, their hair curled and oiled, their fingers glittering with rings, spend the livelong day wheedling presents out of their wealthy admirers. I omit the graver details given in this and other letters of the outraged monk.
