Leo the bishop, to Theodosius Augustus [Emperor Theodosius II].

I. He praises the Emperor's piety and mentions Eutyches' appeal.

Your letter shows once again how much protection the Lord has granted His Church through your clemency and faith, giving us cause to rejoice that within you there is not only an imperial mind but also a priestly one. For beyond your public and imperial duties, you have the most devout concern for the Christian religion — determined that no schisms, heresies, or other offenses should take root among God's people. Your realm is in its best condition when people serve the eternal and unchangeable Trinity by confessing one God. As for the disturbance that occurred in the Church of Constantinople, and what could have so moved my brother and fellow bishop Flavian that he deprived Eutyches the presbyter of communion — I have not yet been able to understand the situation clearly. Although the said presbyter sent a written complaint about his troubles to the Apostolic See, he only touched briefly on a few points, insisting that he upheld the decrees of the Council of Nicaea and had been wrongly accused of holding unorthodox beliefs.

II. He finds fault with Flavian's silence.

But the statement of Bishop Eusebius [of Dorylaeum], his accuser — copies of which the said presbyter has sent us — contained nothing clear about his objections. Though he charged a presbyter with heresy, he did not state specifically what teaching he disapproved of, even as the bishop himself also professed adherence to the decrees of the Nicene council. For this reason, we had no way to learn anything more. Since the proper conduct of our Faith and the commendable concern shown by your piety require the facts of the case to be known, there must now be no room for deception. We must be informed of the specific points on which he considers him unsound, so that a right judgment may be made after full investigation. I have sent a letter to the aforementioned bishop, from which he will see that I am displeased at his continued silence on what has happened in so serious a matter — when he should have disclosed everything to us from the beginning. We believe that even after this reminder he will share the full details with us, so that when what now seems unclear has been brought into the open, judgment may be passed in accordance with the teaching of the Gospels and the Apostles. Dated February 18, in the consulship of the illustrious Asturius and Protogenes (449).
