"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 Nicaea, 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 Coelestine, 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.
