To my lord, in all things most holy and most blessed brother and co-minister Hormisdas, John, bishop, greetings in the Lord.

When the letters of Your Holiness were delivered to me, most beloved brother in Christ, through the most distinguished Count Gratus, and now through the most reverend bishops Germanus and John, the most holy deacons Felix and Dioscorus, and the presbyter Blandus, I rejoiced in the spiritual charity of Your Holiness, because you seek the unity of the most holy Churches of God according to the ancient tradition of the Fathers, and you hasten with zeal to repel (or drive out with love) the tearers-apart of the rational flock of Christ.

Know, therefore, with certainty, most holy one, that, as I have written to you, I am of one mind with you in the truth. I, too, reject all the heretics you have repudiated, loving peace. For I accept that the most holy Churches of God—that is, your supreme Church and this new Rome—are one; I affirm that the See of the Apostle Peter and this August city are one. I assent to all the acts of those four holy synods, namely Nicaea, Constantinople, Ephesus, and Chalcedon, concerning the confirmation of the faith and the state of the Church, and I permit no wavering from their well-judged decisions.

Moreover, I know that those who strive—or have striven—to disturb even a single point of their decrees have fallen from the holy, universal, and apostolic Church of God. Using your rightly spoken words clearly, I declare through this present writing: The first salvation is to guard the rule of the true faith and in no way to deviate from the tradition of the Fathers; for the saying of our Lord Jesus Christ cannot be overlooked, when He says, “You are Peter, and upon this rock I will build My Church” (Matthew 16:18). These words are proven by their effects in reality: for in the Apostolic See, the Catholic religion is always preserved inviolable.

Desiring, therefore, not to fall from this faith and following in all things the decrees of the Fathers, we anathematize all heresies, but especially the heretic Nestorius, who was once bishop of the city of Constantinople, condemned at the Council of Ephesus by the blessed Pope Celestine of the city of Rome and by the venerable Cyril, bishop of the city of Alexandria. Together with him, we anathematize Eutyches and Dioscorus, bishop of the city of Alexandria, condemned at the holy Synod of Chalcedon, which we venerate, follow, and embrace—a synod that, following the holy Synod of Nicaea, proclaimed the apostolic faith.

To these we join Timothy, the parricide surnamed Aelurus, whom we anathematize, along with his disciple and follower in all things, Peter of Alexandria, whom we likewise condemn. Similarly, we anathematize Acacius, once bishop of the city of Constantinople, an accomplice and follower of their errors, as well as those who persist in their communion and participation—for whoever embraces their communion incurs a similar judgment in condemnation. In like manner, we condemn Peter of Antioch, anathematizing him with his followers and all the aforementioned.

Whence we approve and embrace all the letters of the blessed Pope Leo of the city of Rome, which he wrote concerning the true faith. Wherefore, as we have said, following the Apostolic See in all things and proclaiming all that it has decreed, I hope that I will be in one communion with you, which the Apostolic See proclaims, in which lies the full and perfect solidity of the Christian religion.

We promise that in the future, those separated from the communion of the Catholic Church—that is, those who do not consent in all things to the Apostolic See—shall not have their names recited among the sacred mysteries. But if I should ever attempt to waver in any way from this my profession, I profess myself, by my own condemnation, to be a consort of those whom I have condemned. To this profession I have subscribed with my own hand and directed it through this writing to you, Hormisdas, holy and most blessed brother and pope of great Rome, through the above-mentioned venerable bishops Germanus and John, the deacons Felix and Dioscorus, and the presbyter Blandus.

And in another hand:
John, by the mercy of God, bishop of Constantinople, New Rome, consenting to this my profession and all the above, have subscribed in sound mind in the Lord. Given on the 27th (or 28th) day of March, in the twelfth indiction, during the consulship of our lord Emperor Justin Augustus and Eutharicus, most distinguished man (in the year of our Lord 519).
