Theodoret of Cyrrhus → deaconesses, daughters of Terentius

To the Deaconess Celarina,

The flames of the war against us have been lit again. After yielding for a time, the enemy of mankind has armed against us once more -- men nurtured on lies who openly slander me, claiming that I divide our one Lord Jesus Christ into two sons.

I, however, know the distinction between Godhead and manhood, and I confess one Son: God the Word made man. I affirm that he is God eternal, who became man at the end of days -- not through any change in the Godhead, but through the assumption of human nature.

There is no need to explain my views to your piety at length, for you have precise knowledge of what I preach and how I instruct the uninformed.

But I beg you: since these fabricators of lies have poured their insults on all the godly bishops of the East at once and overwhelmed the churches with a storm, show all possible zeal on behalf of the gospel teaching and the peace of the churches. The most devout bishops have left the churches in their care, braved the harshness of winter, and endured the hardships of a long journey in order to calm the tempest. I am confident that your pious excellency will receive them as champions of the faith and guardians of the churches.
