Leo, Bishop of Rome, to the clergy, dignitaries, and people residing at Constantinople.

I. He congratulates them on their forthright resistance to error

Though we are deeply grieved by what is reported to have taken place recently at the council of priests at Ephesus -- because, as consistent testimony and the results themselves demonstrate, neither proper moderation nor fidelity to the faith was observed there -- yet we rejoice in your devoted loyalty and in the acclamations of the holy people. The instances that have been brought to our attention have won our approval, showing the righteous convictions of you all. For there lives and abides in good children the proper affection for their worthy Father, and you do not allow the fullness of Catholic teaching to be corrupted in any respect.

As the Holy Spirit has revealed to you, those who deny that the only-begotten Son of God assumed our nature's true humanity and who maintain that all His bodily actions were merely the actions of a phantom are allied with the Manichaeans' error. Lest you give your assent in any way to this blasphemy, we have now sent you, beloved, through my son Epiphanius and Dionysius, notary of the Roman Church, letters of encouragement in which we have rendered you of our own initiative the assistance you sought. You may rest assured that we are bestowing upon you all the care of a father, and that we are laboring in every way, with the help of God's mercy, to destroy every stumbling block that ignorant and foolish men have raised.

Let no one dare to parade his priestly office if he can be shown to hold such detestably blasphemous opinions. For if ignorance is scarcely tolerable in the laity, how much less excusable or pardonable is it in those who govern -- especially when they even dare to defend their false and perverse views, persuading the wavering to agree with them through either intimidation or flattery.

II. Those who deny the truth of Christ's flesh must be rejected

Let such men be excluded by the holy members of Christ's body, and let Catholic liberty not submit to the yoke of unbelievers. For those who deny the nature of our flesh in Christ are to be counted outside the scope of divine grace and outside the mystery of human salvation. They oppose the Gospel and contradict the Creed, nor do they perceive that their blindness leads them into such an abyss that they undermine the truth of the Lord's suffering, the reality of His death, and the genuineness of His resurrection. For if Christ's flesh was not real, then His passion was not real; and if His death was not real, then neither is His resurrection. And if there was no true resurrection, then our faith is in vain and our hope is empty.

Every recipient of the Holy Eucharist refutes these heretics at the altar. When we receive the body and blood of Christ, we proclaim what we believe: that the flesh we receive is real flesh, and that the sacrifice offered for us was a true sacrifice. No mouth that receives this mystery should be permitted to deny the truth it confesses.

III. They should stand firm and await the remedy of a general council

We exhort you, therefore, beloved, to stand firm in the faith that you have so gloriously confessed. Do not be shaken by the violence that has been done, and do not suppose that the reckless proceedings at Ephesus represent the mind of the universal Church. We are laboring with all our strength to secure a remedy through a general council that will restore what has been overthrown and heal what has been wounded. The cause of the faith belongs to all, and with God's help, the truth that has been assaulted will prevail.

In the meantime, hold fast to the teaching of the Apostles and the Fathers. The faith that conquered the world cannot be overcome by the machinations of one bishop. Christ Himself, whose cause this is, will defend His own truth and vindicate those who confess it.
