"And first, he approves of Cyril's letters and doctrine; for he writes to him thus: 'We perceive that you hold and maintain all that we hold and maintain:' and to Nestorius, 'We have approved, and do approve, the faith of the Prelate of the Church of Alexandria:' and he threatens him with extremities, "If you preach not that which Cyril preaches.' Nothing could be said more marked. Nor does he only approve Cyril's doctrine, but disapproves, too, the perverse dogma of Nestorius: 'We have seen,' he says, 'your letters containing open blasphemy;' and that distinctly, because he was unwilling to call the Blessed Virgin 'Mother of God:' and he decrees that he should be deprived of the episcopate and communion, unless, within ten days from the date of the announcing of the sentence, he openly rejects this faithless innovation, which endeavours to separate what Scripture joineth together, that is, the Person of Christ. Here is the doctrine of Nestorius expressly disapproved, and a sentence of the Roman Pontiff on a matter of faith most clearly pronounced under threat of deposition and excommunication: then, that nothing be wanting, the holy Pope commits his authority to Cyril to carry into execution that sentence, 'associating,' he saith to Cyril, 'the authority of our See, and using our person, place, and power:' so to Nestorius himself; so to the Clergy of Constantinople; so to John of Antioch, then the Bishop of the third or fourth Patriarchal See; so to Juvenal, Bishop of the Holy City, whom the Council of Nice had ordered to be especially honoured: so he writes to the other Bishops also, that the sentence given may be duly and in order made known to all. Cyril proceeds to execute his office, and performs all that he had been commanded. He promulgates and executes the decrees of Cœlestine; declares to Nestorius, that after the ten days prescribed and set forth by Cœlestine, he would have no portion, intercourse, or place with the Priesthood. Nothing evidently is wanting to the Apostolical authority being most fully exercised; but whether the sentence put forward with such authority, after a great dissension had arisen and mention been made of an Ecumenical Council, was held to be final, the succeeding acts will demonstrate.
"We have often said—we shall often say—that it is the constitution of the Church only in extraordinary cases and dissensions to recur, of necessity, to an Ecumenical Council. But in the usual order even the most important questions on the faith, when they arise, are terminated by the consent of the Church being added to the decree of the Roman Pontiff. This is clearly manifest from the cause of Nestorius. We confess plainly that the sentence of Cœlestine would have been sufficient, as Cyril hoped, to repress the new heresy, had not great commotions arisen, and the matter seemed of such a nature as to be referred to an Ecumenical Council. But Nestorius, Bishop of the royal city, possessed such influence, had deceived men's minds with such an appearance of piety, had gained so many Bishops, and enjoyed such favour with the younger Theodosius and the great men, that he could easily throw everything into commotion; and thus there was need of an Ecumenical Council, the question being most important, and the person of the highest dignity; because many Bishops, amongst these almost all of the East, that is, of the province of Antioch, and the Patriarch John himself, were ill disposed to Cyril, and seemed to favour Nestorius; because men's feelings were divided, and the whole empire of the East seemed to fluctuate between Cyril and Nestorius. Such was the need of an Ecumenical Council.
"To this must be added the prayers of the pious and orthodox; here were most pious monks, who had suffered much from Nestorius for the orthodox faith, and the expression, 'Mother of God,' supplicating the Emperor 'for a sacred and Ecumenical Council to assemble, by the presence of which he should unite the most holy Church, bring back the people to one, and restore to their place the Priests who preached the pure faith, before that impious doctrine (of Nestorius) crept wider.' And again, 'We have asked you to call together an Ecumenical Council, which can most fully consolidate and restore the tottering.' Here, after the judgment of the Roman Pontiff, a firm and complete settling of the tottering state of things is sought for by the pious in an Ecumenical Council.
"The Emperor, moved by these and other reasons, wrote to Cyril,—'It is our will that the holy doctrine be discussed and examined in a sacred Synod, and that be ratified which appeareth agreeable to the right faith, whether the wrong party be pardoned by the Fathers or no.'
"Here we see three things: first, after the judgment of St. Cœlestine, another is still required, that of the Council; secondly, that these two things would rest with the Fathers, to judge of doctrine and of persons; thirdly, that the judgment of the Council would be decisive and final."
"He adds, 'those who everywhere preside over the priesthood, and through whom we ourselves are and shall be professing the truth, must be judges of this matter; on whose faith we rest.' See in whose judgment is the final and irreversible authority.
"Both the Emperor affirmed, and the Bishops confessed, that this was done according to the Ecclesiastical Canons. And so all, and Cœlestine himself, prepared themselves for the Council. Cyril does no more, though named by Cœlestine to execute the pontifical decree. Nestorius remained in his original rank; the sentence of the universal Council is awaited; and the Emperor had expressly decreed, 'that before the assembling and common sentence of the most holy Council, no change should be made in any matter at all, on any private authority.' Rightly, and in order; for this was demanded by the majesty of an universal Council. Wherefore, both Cyril obeyed and the Bishops rested. And it was established, that although the sentence of the Roman Pontiff on matters of faith, and on persons judged for violation of the faith, had been passed and promulged, all was suspended, while the authority of the universal Council was awaited. This we have seen acted on by the Emperor, acquiesced in by the Bishops and the Pope himself. The succeeding acts will declare that it was approved in the Ecumenical Council itself.
"Having gone over what preceded the Council, we review the acts of the Council itself, and begin with the first course of proceeding. After, therefore, the Bishops and Nestorius himself were come to Ephesus, the universal Council began, Cyril being president, and representing Cœlestine, as being appointed by the Pontiff himself to execute his sentence. In the first course of proceeding this was done. First, the above-mentioned letter of the Emperor was read, that an Ecumenical Council should be held, and all proceedings in the mean time be suspended: this letter, I say, was read, and placed on the acts, and it was approved by the Fathers, that all the decrees of Cœlestine in the matter of Nestorius had been suspended until the holy Council should give its sentence. You will ask if it was the will of the Council merely that the Emperor should be allowed to prohibit, in the interim, effect being given to the sentence of the Apostolic See. Not so, according to the acts; but rather, by the intervention of a General Council's authority, (the convocation of which, according to the discipline of those times, was left to the Emperor,) the Council itself understood that all proceedings were of course suspended, and depended on the sentence of the Council. Wherefore, though the decree of the Pontiff had been promulged and notified, and the ten days had long been past, Nestorius was held by the Council itself to be a Bishop, and called by the name of Most Religious Bishop, and by that name, too, thrice cited and summoned to take his seat with the other Bishops in the holy Council; for this expression, to take his seat, is distinctly written; and it is added, in order to answer to what was charged against him. For it was their full purpose that he should recognise, in whatever way, the Ecumenical Council, as he would then afterwards be, beyond doubt, answerable to it; but he refused to come, and chose to have his doors besieged with an armed force, that no one might approach him.
"Thereupon, as the Emperor commanded, and the Canons required, the rule of faith was set forth, and the Nicene Creed read, as the standard to which all should be referred, and then the letters of Cyril and Nestorius were examined in order. The letter of Cyril was first brought before the judgment of the Council. That letter, I mean, concerning the faith, to Nestorius, so expressly approved by Pope Cœlestine, of which he had declared to Cyril, 'We see that you hold and maintain all that we hold and maintain;' which, by the decree against Nestorius, published to all churches, he had approved, and, wished to be considered as a canonical monition against Nestorius: that letter, I repeat, was examined, at the proposition of Cyril himself, in these words: 'I am persuaded that I have in nothing departed from the orthodox faith, or the Nicene Creed; wherefore I beseech your Holiness to set forth openly whether I have written this correctly, blamelessly, and in accordance with that holy Council.'
"And are there those who say that questions concerning the faith, once judged by the Roman Pontiff on his Apostolical authority, are examined in general Councils, in order to understand their contents, but not to decide on their substance, as being still a matter of question? Let them hear Cyril, the President of the Council; let them attend to what he proposes for the inquiry of the Council: and though he were conscious of no error in himself, yet, not to trust himself, he asked for the sentence of the Council in these words: 'whether he had written correctly and blamelessly, or not.' This Cyril, the chief of the Council, proposes for their consideration. Who ever even heard it whispered, that after a final and irreversible judgment of the Church on a matter of faith, any such inquiry or question was made? It was never so done, for that would be to doubt about the faith itself, when declared and discussed. But this was done after the judgment of Pope Cœlestine: neither Cyril, nor any one else, thought of any other course: that, therefore, was not a final and irreversible judgment.
