The Pope wrote letters to the emperor, to the empress, to the count Justinian, especially to the bishop of Constantinople, recommending his legates, and exhorting the bishop to complete the work which was begun by condemning Acacius and his followers; also to the archdeacon Theodosius and the clergy of Constantinople.[104] He points out especially that he wants nothing new, or unusual, or improper, for Christian antiquity had ever avoided those who had associated with persons condemned; whoever teaches what Rome teaches, must also condemn what Rome condemns; whoever honours what the Pope honours, must likewise detest what he detests. A perfect peace admits of no division. The worship of one and the same God can only hold its truth in the unity of confession which embodies the belief.

The papal legates were received honourably on their journey, and found the bishops in general disposed to sign the formulary issued by the Pope. In March, 519, they came to Constantinople, where they found the greatest readiness. The patriarch John took the formulary, and gave it the form of a letter, which seemed to him more honourable than a formulary such as those who had fallen would sign. He prefixed to the document which the Pope required to be subscribed the following preface:

"Brother most dear in Christ, when I received the letters of your Holiness, by the noble count Gratus, and now by the bishops Germanus and John, the deacons Felix and Dioscorus, the priest Blandus, I rejoiced at the spiritual charity of your Holiness, in bringing back the unity of God's most sacred churches, according to the ancient tradition of the fathers, and in hastening to reject those who tear to pieces Christ's reasonable flock. Be then assured that, as I have written to you, I am in all things one with you in the truth. All those rejected by you as heretics I also reject for the love of peace. For I accept as one the most holy churches of God, yours of elder, and this of new Rome; yours the See of the Apostle Peter, and this of the imperial city, I define to be one. I assent to all the acts of the four holy councils—that is, of Nicæa, Constantinople, Ephesus, and Chalcedon—done for the confirmation of the faith and the state of the Church, and suffer nothing of their good judgments to be shaken; but I know that those who have endeavoured to disturb a single iota of their decrees have fallen from the holy, universal, and apostolical Church; and using plainly your own right words, I declare by this present writing,"[105] &c.

This is the preface given to his letter by the patriarch John; he then adds the formulary issued by the Pope from his council in Rome as the terms of restored communion between the East and West.

"The first condition of salvation is to maintain the rule of a right faith, and to deviate no whit from the tradition of the fathers; because the decree of our Lord Jesus Christ cannot be passed over, in which He says, 'Thou art Peter, and upon this rock I will build My Church '. These words are proved by their effect in deed, because the Catholic religion is ever kept inviolate in the Apostolic See. Desiring, therefore, not to fall from this faith, and following in all thing the constitutions of the fathers, we anathematise all heresies, but especially the heretic Nestorius, formerly bishop of Constantinople, condemned in the Council of Ephesus by Cœlestine, Pope of Rome, and the venerable Cyril, bishop of Alexandria; and together with him we anathematise Eutyches and Dioscorus, bishop of Alexandria, condemned in the holy Council of Chalcedon, which we follow and embrace with veneration, which followed the holy Nicene Council, and set forth the apostolic faith. To these we join Timotheus the parricide, surnamed Ailouros, and anathematise him, condemning in like manner Peter of Alexandria, his disciple and follower in all things; so also we anathematise Acacius, formerly bishop of Constantinople, who became their accomplice and follower, and those who persevere in communion and participation with them; for whoever embraces the communion of condemned persons shares their judgment. In like manner we condemn and anathematise Peter of Antioch, with all his followers. Hence we approve and embrace all the letters of St. Leo, Pope of Rome, which he wrote in the right faith. Therefore, as aforesaid, following in all things the Apostolic See, we preach all which it has decreed; and therefore I trust to be with you in that one communion which the Apostolic See proclaims, in which the solidity of the Christian religion rests entire and perfect,[106] promising that these who in future are severed from the communion of the Catholic Church, that is, who do not in all things agree with the Apostolic See, shall not have their names recited in the sacred mysteries. But if I attempt in aught to vary from this my profession, I declare that by my own condemnation I partake with those whom I have condemned. I have subscribed with my own hand to this profession, and directed it in writing to thee, Hormisdas, my holy and most blessed brother, and Pope of Great Rome, by the above-named venerable bishops, Germanus and John, the deacons Felix and Dioscorus, the priest Blandus."

The names of Acacius, Fravita, Euphemius, and Timotheus, four bishops of Constantinople, also of the emperors Zeno and Anastasius, who reigned from 474 to 518 (if we include a few months of Basiliscus), were erased from the diptychs in the presence of the legates. After that, at the instance of the emperor, the other bishops, the abbots, and the senate had signed the formulary, a solemn service was celebrated, to the great joy of the people, in the Cathedral on Easter eve, the 24th March, to mark the act of reconciliation, and not the least disturbance took place. The official narration[107] of the five legates to Pope Hormisdas records the enthusiasm with which they were received at Constantinople. "From the palace we went to the church with the vast crowd. No one can believe the exultation of the people, nor doubt that the Divine Hand was there, bestowing such unity on the world. We signify to you that in our presence the name of the anathematised prevaricator, Acacius, was struck out of the diptychs, as likewise that of the other bishops who followed him in communion. So also the names of Anastasius and Zeno. By your prayers peace was restored to the minds of Christians: there is one soul, one joy, in the whole Church; only the enemy of the human race, crushed by the power of your prayer, is in mourning."

The emperor Justin wrote to Pope Hormisdas:

"Most religious Father, know that what we have so long earnestly sought to effect is done. John, the bishop of New Rome, together with his clergy, agrees with you. The formulary which you ordered, which is in agreement with the council of the most holy Fathers, has been subscribed by him. In accordance with that formulary, the mention at the divine mysteries of the prevaricator Acacius, formerly bishop of this city, has been forbidden for the future, as well as of the other bishops who either first came against the apostolic constitutions, or became successors of their error, and remained unrepentant to death. And since all our realm is to be admonished to imitate the example of the imperial city, we have directed everywhere our princely commands, so great is our desire to restore the peace of the Catholic faith to our commonwealth, to gain for my subjects the divine protection. For those whom the same realm contains, the same worship enlightens, what greater blessing can they have than to venerate with one mind laws of no human origin, but proceeding from the Divine Spirit? Let your Holiness pray that the divine gift of unity, so long laboured for by us, may be perpetually preserved."[108]

Thus history tells us that, in the year 484, Acacius, bishop of Constantinople, being condemned by Pope Felix, answered by striking the name of Pope Felix out of the diptychs, and that, in the year 519, the name of Acacius was erased from the diptychs in his own church; that his own successor not only gave up his memory, but, together with 2500 bishops,[109] signed a formulary which attributes to the Roman See the words of our Lord to St. Peter, which declares "that the Catholic religion is ever kept inviolate in the Apostolic See," "in which the solidity of the Christian religion rests entire and perfect," and which lays down the rule that whoever does not live and die in the communion of the Roman See has no claim to commemoration in the Church.

Let us now shortly review the facts which have passed under our notice since St. Leo returned from his interview with the pirate Genseric in the year 455.
