From the great and holy and universal Synod, assembled by the grace of God and the decree of our most pious and Christ-loving Emperors in the city of Chalcedon in the province of Bithynia: to the most holy and blessed Archbishop of Rome, Leo.

I. They congratulate Leo on taking the foremost part in upholding the faith

"Our mouths were filled with joy, and our tongues with exultation" (Psalm 126:2). This prophecy has been rightly fulfilled in us, for whom the security of the faith has been established. What is a greater incentive to joy than the faith? What better cause for exultation than the divine knowledge which the Savior Himself bestowed upon us from above for our salvation, saying: "Go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you" (Matthew 28:19-20)?

This golden chain, leading down from the Author of the command to us, you yourself have faithfully preserved, being appointed as the voice of the blessed Peter to all and imparting the blessing of his faith to all. Therefore we too, wisely taking you as our guide in all that is good, have made known to the children of the Church their inheritance of truth -- giving our instruction not individually and in private, but making our confession of faith in common, with one consent and one voice.

We all rejoiced, feasting as at a royal banquet on the spiritual nourishment that Christ supplied to us through your letter. We seemed to see the heavenly Bridegroom Himself present among us. For if He has said that where two or three are gathered in His name, He is in their midst (Matthew 18:20), how much more intimately must He have been present with five hundred and twenty bishops, who chose the spread of His knowledge above their homeland and their comfort? Of these you were the chief, as the head is to the members, representing your authority through those who stood in your place.

II. The definitions of the Council

Following your lead, we drove out the madness of Eutyches and confirmed the true faith. Just as night yields to day, so did error yield to the proclamation of truth when the voice of Peter spoke through the voice of Leo. We all joined as one in the hymn of the faith: two natures in one Christ, without confusion, without change, without division, without separation. We embraced the doctrine set forth in your letter to Flavian of blessed memory, recognizing it as the authentic teaching of the Apostle Peter through his successor.

The heresy of Nestorius, which divided Christ, and the heresy of Eutyches, which dissolved His true humanity, have both been condemned. The Council has defined the faith in terms that leave no room for ambiguity: our Lord Jesus Christ is truly God and truly man, consubstantial with the Father in His divinity and consubstantial with us in His humanity, born of the Virgin Mary as to His manhood -- one and the same Christ, Son, Lord, Only-begotten, made known in two natures without confusion, without change, without division, without separation. The distinction of the natures is in no way abolished by their union; rather, the character of each nature is preserved and comes together in one Person and one subsistence.

III. They request Leo's confirmation

We ask Your Holiness to confirm by your authority what has been decreed, so that as you led us in the faith through your letter, you may now set the seal upon the work of the whole Council. We also ask that you bestow due honor upon the see of Constantinople, which the Council, following ancient custom and the dignity of the imperial city, has determined should hold the second rank after the most holy see of Rome. We trust that Your Holiness will approve this arrangement, seeing that it was made with the reverence due to the Apostolic See and in accord with the wishes of the most pious emperor.

The grace of God and the prayers of Your Holiness will continue to sustain us.
