The first letter from Flavian, Bishop of Constantinople, to Pope Leo.

I. The devil's scheming has led Eutyches astray

To the most holy and God-loving father and fellow bishop Leo: Flavian sends greetings in the Lord.

Nothing can restrain the devil's wickedness -- that restless evil, full of deadly poison (James 3:8). "Above and below it prowls, seeking whom it may devour" (1 Peter 5:8). Therefore we must be watchful, sober in prayer, drawing near to God, shunning foolish controversies, and following the Fathers rather than transgressing the ancient boundaries. This we have learned from Holy Scripture. And so I set aside my overwhelming grief and bitter tears over the capture of one of the clergy under my charge, whom I could not save or snatch from the wolf, though I was ready to lay down my life for him. How was he caught? How did he leap away, hating the voice of the one who called him, turning his back on the memory of the Fathers, and thoroughly despising their ways? Let me now give my account.

II. The seductions of heretics ensnare the unwary

There are some who come "in sheep's clothing, but inwardly are ravenous wolves" (Matthew 7:15), whom we recognize by their fruit. These men seem at first to be of us, "but they are not of us; for if they had been of us, they would have continued with us" (1 John 2:19). But when they spew out their impiety, throwing off the disguise that concealed them, they seize upon the weaker and those whose understanding of divine truth is untrained, and drag them along to destruction -- twisting and abusing the Fathers' teaching, just as they distort the Holy Scriptures to their own ruin. We must be on our guard against them, lest some be misled by their wickedness and shaken in their firmness. For "they have sharpened their tongues like serpents; the poison of vipers is under their lips" (Psalm 140:3), as the prophet has cried out concerning them.

III. The heresy of Eutyches stated

Just such a man has now revealed himself among us: Eutyches, for many years a presbyter and archimandrite, who pretended to hold the same faith as ours and to have right belief within him. He resists the blasphemy of Nestorius and feigns a quarrel with him; but the creed composed by the 318 holy Fathers, and the letter that Cyril of holy memory wrote to Nestorius, and Cyril's further letter on the same subject to the Eastern bishops -- all writings to which the whole Church has given its assent -- Eutyches has attempted to overturn, reviving the old, wicked doctrines of the blasphemous Valentinus and Apollinaris. He has not feared the warning of the True King: "Whoever causes one of these little ones to stumble, it would be better for him that a millstone were hung around his neck and he were cast into the depths of the sea" (Matthew 18:6).

Casting aside all shame and throwing off the cloak that covered his error, he openly persisted before our holy synod in saying that our Lord Jesus Christ ought not to be understood as having two natures after the Incarnation, nor that the flesh of the Lord is of the same substance as ours. He confessed that the holy Virgin is of the same substance as ourselves, but asserted that the Lord did not take flesh of the same substance as ours from her, so that the Lord's body is not truly the body of a man -- though it appeared to men as a human body.

When Eutyches was asked to accept the creed of the 318 Fathers and the letters of Cyril, he refused. Accordingly, he was deposed by the synod and stripped of all priestly dignity for his estrangement from the true faith, as the acts of the synod, which we have sent to Your Holiness, will make clear. We have written this account so that what has been done here may be known to Your Holiness, and so that, since this matter concerns the faith of the whole Church, you may make known to us and to all what you decide, for the confirmation of what has been rightly done.
