VI. The wrong and mischievous concession of Eutyches. The terms on which he may be restored to Communion. The sending of deputies to the east.
But when during your cross-examination Eutyches replied and said, “I confess that our Lord had two natures before the union but after the union I confess but one,” I am surprised that so absurd and mistaken a statement of his should not have been criticised and rebuked by his judges, and that an utterance which reaches the height of stupidity and blasphemy should be allowed to pass as if nothing offensive had been heard: for the impiety of saying that the Son of God was of two natures before His incarnation is only equalled by the iniquity of asserting that there was but one nature in Him after “the Word became flesh.” And to the end that Eutyches may not think this a right or defensible opinion because it was not contradicted by any expression of yourselves, we warn you beloved brother, to take anxious care that if ever through the inspiration of God's mercy the case is brought to a satisfactory conclusion, his ignorant mind be purged from this pernicious idea as well as others. He was, indeed, just beginning to beat a retreat from his erroneous conviction, as the order of proceedings shows, in so far as when hemmed in by your remonstrances he agreed to say what he had not said before and to acquiesce in that belief to which before he had been opposed. However, when he refused to give his consent to the anathematizing of his blasphemous dogma, you understood, brother, that he abode by his treachery and deserved to receive a verdict of condemnation. And yet, if he grieves over it faithfully and to good purpose, and, late though it be, acknowledges how rightly the bishops' authority has been set in motion; or if with his own mouth and hand in your presence he recants his wrong opinions, no mercy that is shown to him when penitent can be found fault with: because our Lord, that true and “good shepherd” who laid down His life for His sheep and who came to save not lose men's souls, wishes us to imitate His kindness; in order that while justice constrains us when we sin, mercy may prevent our rejection when we have returned. For then at last is the true Faith most profitably defended when a false belief is condemned even by the supporters of it.
Now for the loyal and faithful execution of the whole matter, we have appointed to represent us our brothers Julius Bishop and Renatus priest [of the Title of S. Clement], as well as my son Hilary, deacon. And with them we have associated Dulcitius our notary, whose faith is well approved: being sure that the Divine help will be given us, so that he who had erred may be saved when the wrongness of his view has been condemned. God keep you safe, beloved brother.
The 13 June, 449, in the consulship of the most illustrious Asturius and Protogenes.
