Leo, bishop of the city of Rome, to Pulcheria Augusta [Empress Pulcheria — sister of Theodosius II and later wife of Emperor Marcian; a powerful champion of orthodox Christianity who helped convene the Council of Chalcedon].

I. He rejoices at Pulcheria's zeal against both Nestorius and Eutyches.

What we have always expected concerning your Grace's holy purposes, we have now proved fully true: that however varied the attacks of wicked men upon the Christian Faith, when you are present and prepared by the Lord for its defense, it cannot be overthrown. For God will not forsake either the mystery of His mercy or the merits of your labors, through which you long ago repelled the cunning enemy of our holy religion from the very heart of the Church. When the impiety of Nestorius failed to maintain his heresy, it was because it did not escape you — the handmaid and student of the Truth — how much poison was being injected into simple folk through the polished falsehoods of that glib man. And the sequel to that great struggle was that through your vigilance, the schemes the devil contrived through Eutyches also did not escape detection. Those who had chosen one side of the twofold heresy [Nestorianism on one extreme and Eutychianism on the other] were overthrown by the one and undivided power of the Catholic Faith. This, then, is your second victory over the destruction of Eutyches' error. If he had possessed any soundness of mind — that error having been long ago routed and put to shame in the person of its originators — he could easily have avoided trying to rekindle smoldering ashes, and thus only share the fate of those whose example he followed, most glorious Augusta. We therefore wish to rejoice and offer our prayers for your clemency's prosperity to God, who has already bestowed on you a double crown throughout all the regions of the world where the Lord's Gospel is proclaimed.

II. He thanks her for her aid to the Catholic cause and explains his wishes about restoring the fallen bishops.

Your clemency should therefore know that the whole church of Rome is deeply grateful for all your faithful deeds — whether that you have with pious zeal supported our representatives throughout and brought back the Catholic priests who had been expelled from their churches by an unjust sentence, or that you have arranged for the honorable restoration of the remains of that innocent and holy priest, Flavian, of blessed memory, to the church he led so well. In all of this your glory is abundantly increased, as long as you honor the saints according to their merits and work to remove the thorns and weeds from the Lord's field. But we learn both from the report of our delegates and from that of my brother and fellow bishop Anatolius [Patriarch of Constantinople] — whom you graciously recommend to me — that certain bishops are requesting reconciliation for those who appear to have given their consent to heretical proceedings, and desire Catholic communion for them. We grant this request on condition that the benefit of peace should not be extended to them until — with our delegates working alongside the aforementioned bishop — they are corrected, and with their own hand condemn their wrongdoing. For our Christian religion requires both that true justice constrain the obstinate, and that love not reject the penitent.

III. He commends certain bishops and churches to her care.

Because we know how much pious care your Grace devotes to Catholic priests, we have directed that you be informed that my brother and fellow bishop Eusebius is living with us and sharing our communion. We commend his church to you, for the man improperly claimed to have been elected in his place is said to be ravaging it. We also ask of your Grace — which we have no doubt you will do of your own accord — that you extend the favor that is due both to my brother and fellow bishop Julian and to the clergy of Constantinople who remained faithfully loyal to the holy Flavian. On all matters, we have given our delegates full instructions about what ought to be done and arranged. Dated April 13, in the consulship of the illustrious Adelfius (451).
