To my holy and beloved brother in God, Hormisdas, John sends greetings in the Lord.

When God performs His wonders among His people, it is fitting to exclaim with the words of Scripture, which contain divine teachings: “Who shall declare the mighty acts of the Lord or make all His praises heard at all times?” (Psalm 105). Behold, He has raised up a pious prince for the Roman Empire, one whom both the world and the Catholic Church have long needed, and all of humanity desired to see. Therefore, the crown of grace from heaven has rested upon his head, and mercy has been abundantly poured upon him. Throughout his reign, with a loud voice, all glorified the God of all, for He has adorned such a head with such a crown by my hands.

This great emperor has shown the first victory of his battles by clearly defeating the enemy; according to the merit of his virtue, he has wisely established unity among the most holy Churches. His third good deed as ruler was to bring together what was scattered and wisely secure the peace of the world. Therefore, always giving thanks to the great God who wisely governs all things, I have announced to you, the son of peace, the peace that has been brought forth. You, who are beloved of God in all things, should rejoice with the same joy as David when he exulted in the restoration of the Ark of God according to the law (2 Samuel 6:12), and as the apostles truly rejoiced by grace.

Rejoice, therefore, in the Lord with a joy that is fitting for your holiness, and write what is pleasing to your gracious mind, O man of God. For what was once divided is now united, what was scattered is now gathered; those who were far apart are now drawn together. As I have previously written, I understand that both the Churches of Old and New Rome are clearly one, and rightly define their seat as one. I recognize the indivisible union and the harmonious confirmation of both of our Churches with the integrity of judgment.

Therefore, I pray to God that this unity may remain inseparable through the prayers of the holy apostles and your sanctity, through which we ask for the blessing of our most merciful and Christian prince Justin, and his most pious wife, our daughter Euphemia, for many years of peace. I also extend my gratitude for the presence of your most reverend bishops and clergy, for you have sent such peacemakers, worthy of your apostolic See, according to our request. They have maintained the rule of the Fathers without confusion and preserved the undivided faith. Embracing their minds in all things, we have done everything through them to satisfy your holiness. I also extend many greetings to all the brethren in Christ who are with your holiness.
