To Marcian Augustus [Emperor Marcian, who ruled the Eastern Roman Empire 450-457 and convened the Council of Chalcedon].

I. After congratulating the Emperor on his noble conduct, he discourages further open-ended debates about the Faith.

Although I have already replied to your Grace through the Constantinopolitan clergy, upon receiving your clemency's communication through the illustrious city prefect, my son Tatian, I found even greater cause for congratulation. I have learned of your strong eagerness for the Church's peace. This holy desire rightly secures for your empire the same prosperity you seek for religion. For when the Spirit of God establishes harmony among Christian rulers, a twofold confidence spreads throughout the world: the growth of love and faith makes their military power unconquerable in every direction, because with God won over by one united confession of faith, both the falsity of heretics and the hostility of barbarians are simultaneously overcome, most glorious Emperor. With the hope of heavenly aid strengthened by the Emperor's friendship, I venture with all the greater confidence to appeal to your Grace on behalf of the mystery of human salvation: do not allow anyone, through empty and presumptuous cleverness, to treat as uncertain what must be believed as settled. Although we may not depart from the teaching of the Gospels and Apostles by a single word, nor hold any opinion on the Divine Scriptures different from what the blessed Apostles and our Fathers learned and taught, even now in these latter days, ignorant and blasphemous inquiries are being raised — the same ones the Holy Spirit long ago crushed through the disciples of the Truth, as soon as the devil first stirred them up in hearts suited to his purposes.

II. The only questions remaining are which of those who strayed shall be restored, and on what terms.

But it is completely counterproductive that through the foolishness of a few we should be dragged back into hazardous speculations and the warfare of pointless disputes — as if the debate needed to be reopened over whether Eutyches held blasphemous views, or whether Dioscorus [Patriarch of Alexandria who presided over the violent Robber Council of Ephesus in 449] gave a wrong judgment. Dioscorus, in condemning Flavian of holy memory, struck his own death blow and dragged simpler folk down with him. Now that many, as we have learned, have sought the path of repentance and beg forgiveness for their reckless mistakes, what we need to determine is not the content of the Faith — but whose petitions we shall accept, and on what terms. The deeply religious concern that you graciously show regarding the calling of a Synod [the Council of Chalcedon, 451] shall have fully and promptly laid before it everything I judge relevant to the needs of the case, through the delegates who will, God willing, reach your Grace with all speed. Dated April 23 in the consulship of the illustrious Adelfius (451).
