1. Chapter 1

To Flavian commonly called "the Tome."

I. Eutyches has been driven into his error by presumption and ignorance.

Having read your letter, beloved, at the late arrival of which we are surprised, and having perused the detailed account of the bishops' acts, we have at last found out what the scandal was which had arisen among you against the purity of the Faith: and what before seemed concealed has now been unlocked and laid open to our view: from which it is shown that Eutyches, who used to seem worthy of all respect in virtue of his priestly office, is very unwary and exceedingly ignorant, so that it is even of him that the prophet has said: "he refused to understand so as to do well: he thought upon iniquity in his bed." But what more iniquitous than to hold blasphemous opinions, and not to give way to those who are wiser and more learned than ourself. Now into this unwisdom fall they who, finding themselves hindered from knowing the truth by some obscurity, have recourse not to the prophets' utterances, not to the Apostles' letters, nor to the injunctions of the Gospel but to their own selves: and thus they stand out as masters of error because they were never disciples of truth. For what learning has he acquired about the pages of the New and Old Testament, who has not even grasped the rudiments of the Creed? And that which, throughout the world, is professed by the mouth of every one who is to be born again, is not yet taken in by the heart of this old man.

II. Concerning the twofold nativity and nature of Christ.

Not knowing, therefore, what he was bound to think concerning the incarnation of the Word of God, and not wishing to gain the light of knowledge by researches through the length and breadth of the Holy Scriptures, he might at least have listened attentively to that general and uniform confession, whereby the whole body of the faithful confess that they believe in God the Father Almighty, and in Jesus Christ, His only Son, our Lord, who was born of the Holy Spirit and the Virgin Mary. By which three statements the devices of almost all heretics are overthrown. For not only is God believed to be both Almighty and the Father, but the Son is shown to be co-eternal with Him, differing in nothing from the Father because He is God from God, Almighty from Almighty, and being born from the Eternal one is co-eternal with Him; not later in point of time, not lower in power, not unlike in glory, not divided in essence: but at the same time the only begotten of the eternal Father was born eternal of the Holy Spirit and the Virgin Mary. And this nativity which took place in time took nothing from, and added nothing to that divine and eternal birth, but expended itself wholly on the restoration of man who had been deceived: in order that he might both vanquish death and overthrow by his strength, the Devil who possessed the power of death. For we should not now be able to overcome the author of sin and death unless He took our nature on Him and
