For a few months, Leo made strenuous efforts to redeem the prestige of his See. We know, since 1882, that Flavian in turn appealed to Rome, but Leo needed no new incentive. He wrote repeatedly to the pious Pulcheria, to Theodosius, to his "vicar" in Thessalonica, and to the monks, priests, and people of Constantinople. He knew the situation well. Alexandria had defied Constantinople, but the case of Constantinople was weakened by the division of court-factions and the monkish support of Eutyches. It seemed an admirable occasion for Rome to adjudicate, and Leo pressed Theodosius and Pulcheria[64] to summon an Ecumenical Council at Rome. In the thick of the struggle (February, 450), Valentinian III. visited Rome with the court, and Leo, with tears in his eyes, besought the Empress Galla Placidia to work for the Roman Council. Galla Placidia knew no more than the monks about theology, and was more concerned about her wayward daughter Honoria, but she urged Pulcheria to ensure the holding of the Council at Rome. Presently there came from Constantinople the news that Theodosius was dead, Pulcheria was mistress of the court, the eunuch-godfather had been executed, the monk exiled, and the Archbishop Flavian restored to his See.
But the more agreeable aspect of this situation was soon darkened by a report that the people of Constantinople had compelled Pulcheria to contract a virginal marriage with Marcian, and the new Emperor had summoned an Ecumenical Council in the East. Leo, for reasons which we may understand presently, now made every effort to prevent the holding of a Council,[65] but the Emperor would not endanger his position by flouting the Eastern Church, and, on October 8th, some six hundred bishops gathered at Chalcedon. Four Legates represented Leo, and were awarded a kind of presidency of the Council. Leo's great doctrinal letter was received with thunders of applause, and, when it was speedily decided to condemn Dioscorus (who had gone the length of excommunicating Leo), it was one of the Papal Legates who pronounced the sonorous sentence. But all knew that these compliments were the prelude to a very serious struggle.
After the fourteenth session, the Papal Legates and imperial commissioners affected to believe that the business of the day was over. Later in the day, however, a fifteenth session was held, and the two hundred bishops present framed the famous twenty-eighth canon of the Council of Chalcedon. It runs:
As in all things we follow the ordinances of the holy fathers and know the recently read canon of the hundred and fifty bishops [of the Council of Constantinople], so do we decree the same in regard to the privileges of the most holy Church of Constantinople. Rightly have the fathers conceded to the See of Old Rome its privileges on account of its character as the Imperial City, and, moved by the same considerations, the one hundred and fifty bishops have awarded the like privileges to the most Holy See of New Rome.[66]
This drastic restriction of the Roman bishop to the West, and disdainful assurance that the prestige of the city of Rome was the only basis of his primacy, was read in the next session, and the Papal Legates were gravely disturbed. There can be very little doubt that, as Hefele says, the Legates had abstained from the fifteenth session because they knew that this canon would be discussed and passed. There was no secrecy about it, and there was much in previous sessions that led to it. Indeed, it is clear that Leo himself knew of the design, and this probably explains his resistance, which has puzzled many, to the holding of the Council. In the heat of the discussion, the Roman Legate, Boniface, produced this instruction from Leo: "If any, taking their stand on the importance of their cities, should endeavour to arrogate anything to themselves, resist them with all decision."[67] Bishop Eusebius of Dorylæum (the accuser of Eutyches) then said that he had read the third canon of Constantinople to Leo at Rome some time before the Council, and that Leo had assented to it. Leo afterwards denied this, but we must assume that he merely denied having consented, not the reading of the canon to him. It is quite clear that Leo prepared his Legates for this discussion.
It implies no reflection whatever on the character of Leo that he should instruct his Legates diplomatically to obstruct the passing of a canon which he regarded as contrary to a divine ordination. But the next act of his Legates is more serious. Bishop Paschasinus, the chief Legate, produced and read, in Latin, the sixth canon of the famous Council of Nicæa, and the Greeks were amazed to learn, when it was translated, that it awarded the primacy to Rome. There is now no doubt that this was a spurious or adulterated canon, and the feelings of the Greeks, when they consulted the genuine canon, can be imagined. The session closed in a weak compromise. The Legates were allowed to protest that the twenty-eighth canon was passed in their absence, and was injurious to the rights of their Bishop, "who presided over the whole Church." The Greeks politely registered their protest, endorsed the canon, and proceeded to indite a very Greek letter to the Roman Bishop. They express to Leo[68] their deep joy at the successful congress, their entire respect for "the voice of Peter," their loving gratitude that, through his Legates, he had presided over them "as the head over the members"; but they admit that one of their canons did not commend itself to his Legates and they trust that he will at once gratify their Emperor by endorsing it! Christendom was divided into two parts.
The sequel matters little. The Legates returned and declared that the signatures to the canon had been extorted (as Leo afterwards wrote), though this point had been raised in their presence by the imperial commissioners, and its falsity put beyond dispute. To Marcian, to Pulcheria, and to the new Bishop of Constantinople, Anatolius, Leo wrote acrid letters, denouncing the miserable vanity and ambition of Anatolius and the violation of the (spurious) canons of Nicæa. Marcian curtly requested him—almost ordered him[69]—to confirm the results of the Council without delay, and Leo signed the doctrinal decisions. There the matter ended. Rome affected to treat the famous canon as invalid, and the East genially ignored the absence of Leo's signature.[70]
In the midst of his feverish efforts to defeat this Eastern rebellion, Leo was summoned to meet the terrible King of the Huns, and the memory of his triumph, gathering volume from age to age, has completely obliterated his failure to dominate the Greeks. Italy, painfully enfeebled by the Goths, now saw "the scourge of God" slowly descend its northern slopes and prepare for a raid on the south. Leo and a group of Roman officials met Attila on the banks of the Mincio, and the ferocious King and his dreaded Huns meekly turned their backs on Italy and retired to the East. Pen and brush and legend have embellished that wonderful deliverance until it has become a mystery and a miracle, but it was neither mystery nor miracle to the men who first made a scanty record of it. Jornandes[71] following the older historian Priscus, says that Attila was hesitating whether to advance on Rome or no at the moment when Leo and his companions arrived; his officers were trying to dissuade him, and were appealing to his superstition with a reminder of the fate of Alaric after he had sacked Rome. Prosper merely says in his Chronicle that Leo was well received, and succeeded. Idatius, Bishop of Aquæ Flaviæ at the time, does not even mention Leo in his Chronicle. The Huns, he says, were severely stricken by war, by famine, and by some epidemic, and, "being in this plight, they made peace with the Romans and departed."[72] But Rome at the time knew nothing of these fortunate circumstances, and, in the delirious joy of its deliverance, imagined the savage Hun shrinking in awe before its venerable Bishop: kept on imagining, indeed, until some pious fancy of the eighth century believed that the holy apostles had appeared beside the Pope.
When, a few years later (455) a fresh invasion threatened Rome—when the vicious incompetence of the court amid all its desolation set afoot another feud and brought the Vandals from Africa—Leo went out once more to plead for the impoverished city. Genseric was not a savage; the Vandals are libelled by the grosser implication we associate with their name today. Yet he altered not one step of his onward course at the petitions or the threats of the venerable Pontiff. To say that he consented to refrain from slaying or torturing those who submitted, and from firing the city, is merely to say that Leo failed to wring any concession from the largely civilized Vandal. The aged Pontiff sadly returned with his clergy, and for a whole fortnight had to listen in the Lateran Palace to the shrieks of the women who were dragged from their homes, and to receive accounts of the plundering of his churches. The Church of St. Peter and, probably, the Lateran Church alone were spared. And when the Vandal ships had sailed away with their thousands of noble captives, including the Empress Eudoxia, and their mounds of silver, bronze, and marble, Leo had to melt down the larger vessels of the great basilicas to find the necessary chalices for his priests.
