II. The heresy of Eutyches is to be condemned, though his full repentance may lead to his restitution.
But because the healing even of such men must not be neglected, and the most Christian Emperor has piously and devoutly desired a council of bishops to be held, that all error may be destroyed by a fuller judgment, I have sent our brothers Julius the bishop, Renatus the presbyter, and my son Hilary the deacon, and with them Dulcitius the notary, whose faith we have proved, to be present in my stead at your holy assembly, brethren, and settle in common with you what is in accordance with the Lord's will.
To wit, that the pestilential error may be first condemned, and then the restitution of him, who has so unwisely erred, discussed, but only if embracing the true doctrine he fully and openly with his own voice and signature condemns those heretical opinions in which his ignorance has been ensnared: for this he has promised in the appeal which he sent to us, pledging himself to follow our judgment in all things. On receiving our brother and fellow bishop Flavian's letter, we have replied to him at some length on the points which he seems to have referred to us: that when this error which seems to have arisen, has been destroyed, there may be one Faith and one and the same confession throughout the whole world to the praise and glory of God, and that “in the name of Jesus every knee should bow, of things in heaven, and things on earth, and things under the earth, and that every tongue should confess that the Lord Jesus Christ is in the glory of God the Father.”
Dated 13th June in the consulship of the illustrious Asturius and Protogenes (449).
