"And here the question might have been terminated, but for those incidents which induced the Emperor Theodosius the younger to call the Synod of Ephesus. He was the same who had appointed the First Council of Ephesus, under Cœlestine and Cyril.
"Of this Synod St. Leo writes to Theodosius, at first, 'that the matter was so evident, that for reasonable causes the calling of a Synod should be abstained from.' And Flavian likewise seemed to have been against this. But after the Emperor, with good intentions, had convoked the Synod, Leo gives his consent, and sends the letter to the Synod, in which he praises the Emperor for being willing to hold an assembly of Bishops, 'that by a fuller judgment all error may be done away with.' He mentions that he had sent Legates, who, says he, 'in my stead shall be present at the sacred assembly of your Brotherhood, and determine, by a joint sentence with you, what shall please the Lord.'
"Here are three points: first, that in questions of faith it is not always necessary for an Ecumenical Council to be assembled. Secondly, that Leo, great Pontiff as he was, did not decline a judgment, if the cause required it, after the matter had been judged by himself. Thirdly, that, if a Synod were held, it behoved that all error should be done away with by a fuller judgment, and the question be terminated by the Apostolic See, by a joint sentence with the Bishops, in which he acknowledges that full force of consent, so often mentioned by me.
"But after Dioscorus, Bishop of Alexandria, the protector of Eutyches, had done every thing with violence and crime, and not a Council, but an assembly of robbers downright, had been held at Ephesus, then, when the Episcopal order had been divided, and the whole Church thrown into confusion, under the name of the Second Ecumenical Council of Ephesus, Leo himself admits that a new general Council must be held, which should either remove or mitigate all offences, so that there should no longer be either any doubt as to faith, or division in charity. Therefore he perceived that schisms, and such a fluctuation of minds respecting the faith itself, could not be sufficiently removed by his own judgment. And the Pontiff, no less wise and good than resolute, demanded a fuller, firmer, greater judgment, by the authority of a General Council, by which, that is, all doubt might be removed.
"But the Emperor Theodosius would not hear of a new Council, so long as he thought that due order had been preserved at Ephesus. 'For the matter was settled at Ephesus by the deposition of those who deserved it; and a decision having been once passed, nothing else can be determined after it.' Here the difference between the judgments of Roman Pontiffs and of General Councils is very evident; the judgment of the Roman Pontiff being reconsidered in a Council, whereas after a Council, so long as it is held a lawful one, nothing can be reconsidered, nothing heard.
"But as Theodosius shortly afterwards died, the Emperor Marcian, upon understanding that the Ephesine assembly had used violence, and acted otherwise against the Canons, and was therefore refused the name and authority of an Ecumenical Council by most Bishops, but chiefly by the Roman Pontiff, could not deny the calling of a new Council to Leo's request. So the Council of Chalcedon took place, and all admitted that there were certain dissensions on matter of faith so grave, that they can only be settled by the authority of an Ecumenical Council.
"All know that more than six hundred Bishops assembled at Chalcedon. The Bishops Paschasinus and Lucentius presided over the holy Council in Leo's stead. Magistrates were assigned by the Emperor to direct the proceedings, and restrain disorder; but to leave the question of faith and all ecclesiastical matters to the power and judgment of the Council.
"But in this Council two things make for us: first, the deposition of Dioscorus; secondly, the sentence of the Council respecting the approval of Leo's letter.
"With Dioscorus they thus proceeded: when, upon being cited, he refused to present himself to judgment, and his crimes were notorious to all, Paschasinus, Legate of the Apostolic See, asks the Fathers,—'We desire to know what your Holiness determines:' the holy Synod replied, 'What the Canons order.' The Bishop Lucentius said, 'Certain proceedings took place in the holy Council of Ephesus by our most blessed Father Cyril; look into their form, and assign what form you determine on.' The Bishop Paschasinus said, 'Does your piety command us to use Ecclesiastical punishment? Do you consent?' The holy Council said, 'We all consent.' The Bishop Paschasinus said, 'Again I ask, what is the pleasure of your blessedness?' Maximus, Bishop of the great city of Antioch, said, 'We are conformable to whatever seems good to your Holiness.' Thus the initiative, and form, as it was called, was to be given by the Apostolic See. And so the Legates, after recounting the crimes of Dioscorus, thus pronounced: 'Wherefore, holy Leo, by us and this present Council, together with the most blessed Apostle Peter, who is the rock and ground of the Church, and the foundation of the right faith, hath declared him cut off from all sacerdotal power.' Anatolius, Bishop of Constantinople, said, 'As our most blessed Archbishop and Father Leo, so Anatolius.' The rest to the same effect: 'I agree; I am of the same mind; I agree to the condemnation made by the Council; I declare, I decree the same:' and the subscription, 'I, Paschasinus, declare and subscribe;' 'I, Anatolius, declare and subscribe;' and so the rest.
"Thus from Peter the head and source of Unity the sentence began, and then became of full force by common agreement of the Bishops, just as that first Council of the Apostles is always represented.
